An uphill battle?
Doing nothing a sure path to disaster
By Kevin Trenberth
Sunday, June 30, 2002 - The Bush administration has opted out of the
Kyoto Protocol, with its binding targets for emissions, on the grounds
that it would hurt the economy. It is not so clear that this has to be
so, provided that actions are implemented in the right way and, in
particular, in the right time. However, none of the arguments take
into account the very real costs of not doing anything.
Global warming is happening. That is the scientific judgment of the
Intergovernmental Panel on Climate Change, backed up by a special
report from the National Academy of Sciences. What this means is that
the observed changes in the composition of the atmosphere due to human
activities are now well enough established to have recently caused the
global climate to change outside the realm of natural variability of
the past 10,000 years.
In terms of the observed increase in global mean temperatures of 1.2 F
over the past 100 years, about 0.8 F - and probably by 0.7 F just
since 1970 - is likely caused by increases in greenhouse gases in the
atmosphere. Changes in the sun are thought to have contributed to
modest warming in the first half of the 20th century.
There is no longer any argument about whether human activities are
causing global climate change. Instead, it is now about the details,
how much it will amount to in the future, and the impacts and costs.
But many of these arguments seem academic and, of course, they will
remain so until there are proven effects of global warming.
But there is the rub. It is almost impossible to prove that any event
is a consequence of global warming, because climate is made up of the
sum total of weather events. There is always a finite, albeit small,
chance that something weird will happen in the infinite variety of
weather. But, with global warming, the odds of certain kinds of
behavior change.
Global warming arises from increases in greenhouse gases in the
atmosphere. The main source of the problem is the observed buildup in
carbon dioxide primarily from the burning of fossil fuels, and so it
is related to our energy usage. Since carbon dioxide has a lifetime of
more than a century in the atmosphere, emissions accumulate and are
spread around the world.
It is truly a global problem. So far, amounts of carbon dioxide in the
atmosphere have increased by more than 30 percent, mostly since World
War II. The United States contributes about a quarter of the
emissions, much more than any other country.
Because carbon dioxide is a greenhouse gas, it traps the Earth's
radiation and therefore blankets the Earth, causing global heating (or
warming). This causes average global surface temperatures to rise. But
most of the heat at the surface actually goes into evaporating
moisture, creating drying. And once the ground is dry, the temperature
goes up.
And so global warming promotes drying and droughts. And then the
droughts promote heat waves and wildfires. But the moisture that goes
into the atmosphere does not disappear. It gets carried away by winds,
and gathered into storms often hundreds of miles away.
The additional moisture forms fuel for storms, both individual
thunderstorms and major cyclones, with their warm and cold fronts.
Storms are invigorated, and precipitation is heavier than it otherwise
would be, both because the storm is more severe and because there is
more moisture. So the risk of flooding increases. .... (cont)

cheap fossil fuels is going to dry up (or at least make their use
prohibitively expensive for things like coal fired power plants and
automobiles). So what is the difference if we cut back on burning fossil
fuels now (thus extending their use over a longer time period), or we let
the free market decide on when they run out (thus resulting in them being
depleted sooner). Either way we are going to use them all up at some point
and put all that CO2 into the atmosphere. Either way some alternative is
going to have to be found. Either way, pollution control technology will
continue to improve. Is it more harmful to the earth if they are all used
up sooner or if it takes a few hundred extra years to burn through them?
I for one am very glad Bush isn't over reacting to all the hype about global

REAL LIFE, PERSONALLY EXPERIENCED GLOBAL WARMING
Monday, 17 Jun 2002
In Alaska, some 4,000 miles from Capitol Hill, global warming is neither an
abstraction nor up for debate. It's simply a reality -- and not, generally
speaking, a pleasant one. High water is eating away houses and buildings,
mosquitoes are invading where once they were unheard of, hunters are getting
trapped on breakaway ice, permafrost is no longer permanent (meaning building
foundations are slouching and buckling), and on the Kenai Peninsula, a 4 million
acre spruce forest has been killed by hot-weather-happy beetles in the largest
forest loss ever recorded in North America. Sen. Ted Stevens, a Republican, can
hardly take the party line on climate change when he's witnessed the sagging
roads, crumbling towns, dead forests, and catastrophic fires that are
devastating his home state. Mean temperatures in Alaska have risen by 5 degrees
in summer and 10 degrees in winter since the 1970's, federal officials say, and
climate models predict that temperatures will continue to increase over this
century, by up to 18 degrees.
Editor’s notes: In Antarctica and Greenland evidence continues to mount over
melting glaciers. People in Siberia are experiencing similar overwhelming
problems as in Alaska. Islands in the pacific are “sinking”. Another heat-wave
is ravaging southern Europe… And so on.
Incidents written off as hysteria merely three years ago have become
commonplace.

I think 6 degrees is unsupportable even with the lack of good reduction
strategies. However, that is not the point anyway, IMO.
Two statements are made. Are they true?
1: "...There is no longer any argument about whether human activities are
causing global climate change...."
Answer: Untrue as yet. There is no argument about GW occurring and being
primarily due to anthropogenic GHG emissions.
But climate change?? There are huge debates about every new climate
phenomenon, and as yet no clear consensus of what causes them, much less if
that cause is specifically GW.
2: "... It is almost impossible to prove that any event is a consequence of
global warming...."
What level of 'proof' is needed is the first thing that comes to mind. To be
absolutely certain beyond a shadow of a doubt that there is a direct link,
meaning that a warming of X degrees will result in a climate event Y?
No. We are not that definitive about any climate event.
Now, a true and a false statement mean? Nothing. There is no argument here
based on them.
The point is not whether Tropical Storm Alice was due to GW or not. The
question is whether there will be a worsening of climate as a result of a
higher planetary temperature. The answer to THIS question is yes, beyond
ordinaay doubt, mostly due to changes in the hydrological cycle in a warmer
atmposphere.
3: "Then how do we know the solution is reducing our GNP by 7%?"
There is no basis for this statement. Nobody has said that reducing GNP will
reduce GW. It may increase it, if lower cost fuels are substituted for
higher priced natural gas or hydro power, etc. The question is so silly as
to merit a serious sneer in response.
Now, the real question is, given uncertainties in the cost/benefit ratio of
trying to fight a fire, do you fight fires? Why? You cannot predict the
outcome with certainty. You may not even be able to bring the fire into
control, and waste the entire cost. The cost of water, equipment, time, etc
may exceed the value burned. Lives may be lost. All because of a small fire
that may not really exist and if it does may not burn much and if it does
burn a lot, may become too hard to fight, and there may be nothing you can
do about it, so why waste money?

Excuse me, but what did you just say...
The usual generalities and attempts at diversions, I presume.
You're evidently concerned about taxes.
But a lot of us see the problem in more definite, drastic terms.
The first step towards solving a problem, a threat is to realize its existence.
Many people, including you keep insisting it isn't any or you're coming with
your diversions.
Alaska, you see is just one example of many.
The permafrost is melting in Siberia. CO2 is literally rising from the ground.
WAIS (the west Antarctic Ice Shelf to you unenlightened out there) is melting
fast.
The ice at the top of Mount Everest, the highest elevation in the world is
melting.
Animals are found further north than they've ever been.
The growth season in both Canada and Northern have been increased with at
leaast 11 days (conservative estimate two years ago).
These are merely a few out of thousands upon thousands of alarming news, a

WARMING WORLD ON THIN ICE
Rapidly melting glaciers threaten death to millions by making huge areas
uninhabitable
Joanna Walters
Sunday June 9, 2002
The Observer
Ian McNaught-Davis has spent a long time in the mountains. Stocky and affable,
the president of mountaineering's international association, the UIAA, is not
easily fazed. But when he hiked into the glaciers
surrounding the world's highest mountains on a UIAA mission funded by the United
Nations Environment Programme, he was profoundly shocked. For generations of
explorers, environmentalists and local people, these
cold Himalayan valleys, with glaciers that stretch for miles, seemed to
symbolise a kind of cold, brutal permanence. After hiking through zero
visibility and atrocious weather for five days, McNaught-Davis emerged into a
sherpa village surrounded by breathtaking scenery. There he was confronted with
a shocking truth: the glaciers on Everest were melting alarmingly quickly.
McNaught-Davis listened as kinsmen of Nepalese sherpa Tenzing Norgay, who
conquered Everest with Sir Edmund Hillary in 1953, reported a rapid retreat of
the Khumbu glacier from which the two pioneers set out. Sherpas and Buddhist
lamas told him the glacier no longer reached to where Hillary's base camp tents
were pitched: it had melted three miles up the valley. To check their accounts,
McNaught-Davis climbed up to a glacial meltpool at 5,000 metres that 20 years
ago was marked on maps as a series of small ponds.
He found that the ponds had merged into a vast lake more than a mile long. 'It
was huge. I was completely amazed,' he said. 'Further up the glacier you can see
more ponds forming.' And it is happening so quickly
that map makers cannot keep up. Locally, the prospect of these glacial lakes
bursting their banks and obliterating whole villages is frightening. Globally,
McNaught-Davis believes what mountaineers are seeing first is a bellwether for
the climate change affecting us all.
'It is a harbinger, a clue that something terrible is happening. Some
scientists say "It must be other factors", but when you talk to people who have
lived and climbed in these mountains for 60 years they say it
is getting warmer, and the glaciers are shrinking at a sprint.'
Closer to home in the Alps, mountaineers report that rock pillars held on to
their crags by ice for thousands of years are simply crumbling away as the ice
melts. The climbing and skiing resort of Chamonix is under threat in the
longterm, as the peaks around Mont Blanc begin to lose their ice and become more
prone to avalanches.
McNaught-Davis said a recent visit to the Eiger in Switzerland was a shock
too. 'The north face used to have three massive ice fields. The last time I was
there, there was one left, and it was almost gone.'
Glaciers on the African peaks of Kilimanjaro and Mount Kenya are receding
rapidly, and the same is happening in the South American Andes.
It is not only the mountain glaciers that are melting. American Nasa
scientists say the rate at which the huge Greenland ice sheet is melting has
increased by a fifth in the last two decades. This is because more meltwater is
trickling down from the surface of the sheet to the bedrock 1,200 metres below.
The water 'lubricates' the path of the whole sheet, causing it to slip faster
towards the sea. Team member Jay Zwally said such a process had never before
been detected in large ice sheets.
Nasa believes global warming could be to blame - and it is the first time the
scientists (at NASA - editor’s note) have suggested such a link. This pattern is
repeated in all the world's coldest places. Antarctica has been the scene of
huge collapses of ice shelves. In the Arctic, seasonal melting around the North
Pole has led to a suggestion that soon shipping will be able to navigate the
North West Passage from the Atlantic to the Pacific.
All this comes as the world's environment Ministers failed at a meeting in
Bali last week to agree tough action to halt global warming and wipe out
poverty. They now approach the Earth Summit in Johannesburg in August in
disarray and facing accusations of betrayal from environmental groups.
Kate Hampton, international climate campaigner for Friends of the Earth, sees
a direct link between disagreement among Western nations about how to tackle
pollution and the reports of vanishing ice sheets. 'Glaciers are the water
towers of the world - vital for storage. If they are melting fast this has grave
implications for the people who live locally but is also a sign of global
warming.
'Water supplies everywhere are under threat from climate change,' she said.
Water is a vital bargaining chip in any Middle East peace talks. While politics
and religion grab the headlines, shrinking water resources in this dry region
are always a major factor when negotiators draw lines on maps.
Hampton warned that without serious strategies to reverse global warming, the
next few decades would see tens of millions of 'climate refugees' fleeing
regions in Africa and Asia, where extreme drought and floods become the norm.
'What will happen when millions of Bangladeshis from the flood plains are
literally washed out, and end up spilling into poor parts of India?' she said.
In the US scientists are warning that the 'sunshine state' of California could
become the 'desert state'.
The Intergovernmental Conference on Climate Change has already established
that the average temperature on Earth rose by 0.6 C in the twentieth century.
They predict it will be between 1.4 C and 5.8 C warmer by 2100 than it was in
1990. The sea could rise by between nine and 88cms. The higher end of these
forecasts spells an environmental apocalypse. Today it means a few disappointed
ice climbers, but by the end of the century it could mean death for tens of
millions. In Britain the winters are already becoming warmer, with violent
storms and flash floods more frequent. Hampton said the reports of disappearing
Himalayan glaciers confirmed what many scientists and environmentalists had been
saying for a decade.
'This is a serious issue in areas where the people who live there are the
least responsible for causing the problem - industrialised nations are not
getting to grips with this in the face of the most overwhelming evidence,' she
said.
The Kyoto protocol was meant to make the climate targets reached at the Rio
Earth Summit 10 years ago more enforceable. But while the European Union is
preparing to sign up to the protocol this year the US first watered it down,
then walked away from it - holding the world's climate hostage, said Hampton.
Campaigners are worried that what should in effect be an emergency summit to
save the planet in Johannesburg will be at best a farce and at worst a
confirmation of the power of corporate America over the environment - with
President George W. Bush presiding as polluter-in-chief.
Ian McNaught-Davis believes every car-driving Westerner munching fruit flown
in from halfway around the globe must take a share of responsibility for pumping
climate-warming carbon dioxide into the atmosphere.
'It's about time we slowed this whole thing down and stopped it. If the US
would get off their arses, maybe someone would sit up and take notice,' he
added.
Editor’s comment: Japanese scientists has already predicted that the
temperature will rise at least 10 degrees Celsius within the next thirty years,
stating that the IPCC numbers are far too conservative, that they fail totally
to take the acceleration process inherit in the system into account, and that
between 70 to 80 percent of all ice on Earth will melt within the mentioned 30
year period.
This will result in at the very least a 50 meter searise.

nothing to do with GW.
What is known for sure is that the earth's climate will undergo changes all
by itself and mankind cannot stop that from occurring. Even if greenhouse

like it always has in the past. So what is the point of sending the economy

chance that it is broken, no amount of money may be able to fix it. All I
ask is for the decision makers to use common sense and listen to science,
not doomsayers....and I think that's what the Bush administration has done.
If there was a good consensus in the scientific community that found global
warming is a serious problem and needs to be immediately addressed by
spending billions of dollars, I would be on board, and Bush probably would

The permafrost is melting.....OK, we´ll assume this is true. How does

Organic matter trapped in the permafrost can decay much
faster when the icy matrix in which it is trapped melts.
However, the bad scenerio is that vast amounts of
methane will be released if the ground above them
warms.
I think we've discussed the methane hydrate part since
you came in, but the organic decay part is often treated
implicitly.

Perhaps (although there's more and more evidence the earth hasn't been
as hot as it's going to get in 100 years or so, for hundreds of
thousands of years), but the time frame will be drastically different.

Good idea...this is direct from NASA website
(http://earthobservatory.nasa.gov/Library/GlobalWarming/):
"On the other hand, there are those, some of whom are scientists, who
believe that global warming will result in little more than warmer winters
and increased plant growth. They point to the flaws in scientists'
measurements, the complexity of the climate, and the uncertainty in the
climate models used to predict climate change. They claim that attempting to
lower greenhouse emissions may do more damage to the world economy and human
society than any amount of global warming. In truth, the future probably
fits somewhere between these two scenarios. But to gain an understanding of
global warming, it is necessary to get to know the science behind the
issue."
"While the general consensus among scientists is that global warming is real
and its overall effects are detrimental, there are still some prominent
scientists who feel that the threat of global warming has been greatly
exaggerated."
This is almost exactly what I had said in my original post....that there are
reputable scientists on both sides of the issue. Is it 50/50, 70/30 or
30/70 doesn't really matter....it certainly isn't 90% to 10% one way or the
other. If the scientists can't come to a concensus, who am I (or you) to
think we know more than they by discounting one entire side of the
arguement. I'm not trying to say GW isn't occuring...I just don't think
there is enough evidence to show drastic policy changes need to be made
right now.
> That "petition" is a lie and a fraud.
>
Yes I've seen the arguement that the signers were duped into signing
something they didn't understand or they based their entire opinion on one
article included with the mailer. A little difficult for me to believe that
one. The other arguement I found was that the names were all made
up.....also a little difficult to believe. If you have any other good
sources of information that show that petition to be a fraud, I'd like to
check them out. Believe it or not I want to know the truth.

We don't know. Anything we can prove is still subject to an unknown, such as
THC shutdown, methane hydride release, collapse of greenland icesheet (7
meter sea rise ) or WAIS ice sheet collapse (5 meter sea rise), a variable
climate similar to the oscillation we now get between the polar vortexes
causing wild changes in weather over periods of a few weeks, etc, etc. We
only know a few likely scenarios to be certain. No matter what we imagine,
there may be another problem that we haven't even suspected.

These kind of changes would cause crops to fail, and farmlands to be
flooded. The ensuing famine and large scale migrations destabilizes
the global political scene and lead to a new world war where nations
deliberately try to wipe out as many people as possible to get new
space to live, or to avoid beeing flooded by refugees. Using the
doomsday weapons available in 50 years humanity would then proceed to
wipe itself out in an orgy of nuclear and biological warfare.

Correct, it's more like 98% to 2%. And yes, percentages do matter.
There are still scientists who deny the theory of evolution, still

Yet from the very section you quote we read the following....
"While the general consensus among scientists is that global warming is
real and its overall effects are detrimental, there are still some
prominent scientists who feel that the threat of global warming has been
greatly exaggerated."
So is there consensus? Clearly your own quote that you use to try to claim
that there is no consensus, explicitly states that there is.
But denialists do have a habit of ignoring evidence that doesn't confirm
their perverse view of the world.

Drastic policy changes are not being proposed right now. Only a minor
policy change of reducing emissions to the rates of he early 90's.
But drastic policy changes will be made, and made soon. And they will hurt
more than they need to because they were postponed from earlier dates.

Different petition. Then please explain why many of the signatories can
not be found? Explain how some were found to be simply fraudulent?
Explain how the signatories were passed off as scientists when in fact the
list contains political flunkies, politicians, industry shills, weather
jockies, and truck drivers.

Sea level rises several meters. Billions of people are displaced.
Climate changes -- agricultural regions become too dry, or too hot.
Other areas may become warmer, but a lot don't have the soil or the
infrastructure to take up the slack. Hurricanes and other storms
become more numerous and more violent. Tropical diseases move into
other climates. Wetlands become salty, and we not only lose them as
ecosystems but as purifiers of water. Ecosystems and species of plants
and animals are wiped out, as 100 years is too soon for them to adapt.
Glaciers melt, there's less snowfall, and lots of places (like Los
Angeles) depend on snow for their drinking water.

It is, more like 999 to 1, that (1) global warming is occurring and (2)
it's due to human activities.
The debate is over how much, how soon.

Well, if you take away all those who work for(or are funded by, or
have interest in, etc) polluting companies or the politicians who
support them then the scientific community is well above 90% in favour
of global warming being a serious problem that is caused by humans.

Norton is asking what difference would there be if the rate of carbon
entering the atmosphere is lowered.
The difference is clear. When the rate of carbon entering the atmosphere
is lowered below the rate of accumulation then the temperature rise
attributable to the addiitonal CO2 will stop.
It's as simple as that. But apparently simple concepts confuse simple or
dishonest minds.

Exactly correct. When the average global temperature shows no increase it
can't be stated that the globe is warming.
However the global average temperature is observed to be increasing, and
attributed mostly to the gigatonnes of carbon man is pumping into the
atmosphere.

The permafrost is frozen bog. It has a high organic content composed of

fraud. I've looked around on the internet and found a few websites that
claimed the names on the petition were all made up, or that the researchers
were tricked into signing something they didn't understand but that doesn't
seem very plausible. If it were a fraud I would think there would be a
pretty detailed examination of the petion somewhere explaining exactly why
it is a fraud. I've also seen claims that the 2,600 signers of the other
petition included just one climatoligist. So it seems to go both ways.
Then there are statments such as:
"Over one hundred climate scientists signed the 1996 Leipzig Declaration,
which stated in part, "there does not exist today a general scientific
consensus about the importance of greenhouse warming from rising levels of
carbon dioxide. On the contrary, most scientists now accept the fact that
actual observations from earth satellites show no climate warming
whatsoever."
Or
"A survey of 36 state climatologists--scientists retained by state
governments to monitor and research climate issues-- conducted in 1997 found
that 58 percent disagreed with the statement, "global warming is for real,"
while only 36 percent agreed. A remarkable 89 percent agreed that "current
science is unable to isolate and measure variations in global temperatures
caused only by man-made factors."
Believe it or not I am trying to look at both side of this issue with an
open mind....I am just a very skeptical person. But I would like to find
out what the real story behind these two petitions is.

scientific papers indexed by the key phrase "Global Warming,"
as I have, you will find that about 5 years ago the
scientific consensus switched in favor of anthropogenic global
warming. Today, less than 1 in a hundred peer-reviewed
published scientific papers challenge anthropogenic global
warming. Most of the research now deals with the magnitude
of, or the effects of, the problem, not whether the problem
exists.

Google is wonderful, you don't have to write things twice
and you can look stuff up... from an old post of mine:
***********************
Interesting. If you cross-correlate the two lists of signers you find that
of the 80 scientists who signed the Leipzig Declaration, only 19 signed the
OISM petition. Since it appears that the OISM petition was only circulated
in North America, that is 19/53 North Americans signed both documents. or
aqbout 36%.
A real strong endorsement....\

btw, this explains the difference between the 80 listed
above as the number of signers and the over a hundred in
your letter

Well, it turns out that might have been a bit prematures. I
had looked at the list of signatures, but had not done a semi-

Reply To: c...@dmi.min.dk

Subject: Fred Singer's comment on Trenberth's article
How many climate researchers support the
"Leipzig Declaration"?
SNIP....
it prompts scrutiny of the list of over 100
"bone-fide experts" who Singer claims have
signed his so-called Leipzig Declaration
SNIP....
Such an examination has been undertaken by
Danish Broadcasting Company (DR1) journalist,
Xjvind Hesselager (2). In late 1997 he
attempted to contact every signatory (82 at
the time) to the "Leipzig Declaration."
Of 33 European signatories:
there were four he was unable to locate
twelve denied having signed, and of these,
some had not even heard of the "Leipzig Declaration"
many signatories were not qualified in fields
even remotely related to climate research.
They included medical doctors, e.g., H. Metzner;
nuclear scientists, e.g., M.J. Higatsberger; and
one expert on flying insects, i.e., V. Svidersky
some signatories had financial ties to the German
coal industry or the Government of Kuwait (R. Balling and P.
Michaels).
These are hardly reliable authorities on climate research.
Confronted with these facts, Singer removed many from
the list, although not the five mentioned by name above
(Dr. Metzner apparently played a central role in compiling
the list of signatories). Other names were then added to
make a total, today, of more than 100.
Of the present signatories:
twenty-five are TV-meteorologists (here in Denmark,
being a TV-meteorologist does not imply any in-depth
knowledge of climate research)
nine do not appear, from the information provided
in the published list (2), to be involved in relevant
research
fourteen claim the title "Professor," but the list
gives no indication of their academic speciality or
institutional affiliation
forty-two are listed either as an oceanographer,
meteorologist, climatologist, or geophysicist or
as the employee of an institution involved with
climate research. However, in only a minority of cases
is it indicated by the list as currently published
(1) whether these individuals are actually doing
climate research.

> 58 percent disagreed with the statement "global warming is for real,"
Matt, you need to learn how to evaluate your sources.
I found your reference in an on line magazine called Capitalism.com
The article containing the text is entitled
Special Report: Seven Facts About Global Warming - Joseph Bast.
At the end of the article we find the following...
Adapted from The Questionable Science Behind the Global Warming Scare by
Joseph Bast, Heartland Policy Study No. 89 October 30, 1998.
http://www.heartland.org/
Under that I see an anvertisement fot the Ayn Rand Institute, hardly
surprising because the publication Capitalism.com is a publication of the
Ayn Rand Institute.
---
Both the Heartland Institute and the Ayn Rand Institute are funded by
organizations Exxon and Enron whose motivation is to extract the
maximum amount of money from your pocket without conscience and without
care for you or your progeny.
These two organizations are two among several hundred others, like the
Competitive Enterprise Institute, the CATO institute, the Progress in
Freedom Foundation, the Scaif Foundation, the Liberty Institute, etc.
You will find the same cabal of authors regurgitating the same long
disproven propaganda over and over again in the publications of these
criminally deceitful organizations.
These are political organizations, that exist to sponsor a political agenda
rather than promote scientific truth. In fact, these organizations hold
that scientific truth must be oppressed when it doesn't support their tired
political rhetoric.
Consider that the Heritage Foundation wrote glowingly about Enron,
defending the company, claiming that it was acting in the best interest of
the people of California, all the while Enron was breaking the law,
illegally manipulating power prices, and stealing billions from the
California public.
Consider the Competitive Enterprise Institute (CEI) who joined in the game
by regurgitating a claim made by the Greening Earth Society (another
propagand machine funded by the carbon industry) claiming that the reason
for the blackouts in California was not artificial shortages (as was stated
to be the case at the time, and as we now know to be the case), but the
expansion of the internet.
The CEI and the GES were later exposed as liars by scientists from the
Berkely national Science Lab who's opening paragraphs in their response
were as follows....
"In the past year and a half, I have been witness to an extraordinary
event: an analysis based on demonstrably incorrect data and flawed logic
has achieved the status of conventional wisdom, in spite of my and my
colleagues’ best efforts to refute its assertions. The results continue to
be cited by an unsuspecting press, and even by people who ought to know
better.
In May 1999, Mark P. Mills published a report for the Greening Earth
Society (summarized in an article in Forbes Magazine) that attempted to
calculate the "Internet related" portion of electricity use. This report
claimed that electricity use associated with the Internet totaled about 8
percent of all U.S. electricity use in 1998, that the entire “digital
economy” accounted for 13 percent, and that this sector would grow to
consume half of all electricity in the next two decades. Subsequent to the
publication of this report, there was an exchange of technical emails
between Amory Lovins, Joe Romm, Mark Mills, and others
(http://www.rmi.org/images/other/E-MMABLInternet.pdf).
My colleagues and I at Lawrence Berkeley National Laboratory examined
Mills' calculations of Internet-related electricity use in a technical memo
dated December 9, 1999 (Koomey et al. 1999). We found that Mills
significantly overestimated electricity use, in some cases by more than an
order of magnitude. We adjusted his estimates to reflect measured data and
more accurate assumptions, bringing Mills' overall estimate of
total Internet-related electricity use down by about a factor of eight.
..."
In this very newsgroup we have a member posting here by the name of Andrew
Langer, who was one of the propagand officers for the CEI. Several years
ago, he was caught positing CEI disinformation in this newsgroup in clearly
what was an attempt to dishonestly influence those who come here.
In a nutshell Matt, these organizations exist to lie to you and to the
american public. They are funded by corporate interets who see reduced
government oversite as a means of raping the american people.
You have to ask yourself. Who knows more about science? Dishonest
political propagandists from these right wing propaganda organizations? Or
the worlds scientific community?
It is actually very easy to find out what the scientific community is
thinking on this and other issues. Read the science journals, or in lue of
that read the synopsis of the articles as found on reputable science sites.

So which is it Matt? You going to believe the paid political propagandists
or the scientific community?

There's enough known coal in reserve to take the atmospheric CO2
level to at least 12 times the preindustrial. 'at some point' could

Chambers and Brain, of the Centre for Environmental Change and
Quaternary Research at the University of Gloucestershire recently
published a paper describing their research into the shifts in climate
journal publications and what those shifts mean [Paradigm shifts in
late-Holocene climatology? The Holocene 12(2):239-249, 1 March 2002].
They come to conclusions that seem quite contrary to yours. Here's the
abstract:
The climatic consequences of major increases in the concentration of
atmospheric carbon dioxide were calculated over 100 years ago, but
only during the last two decades have the effects of human-induced
increases in various atmospheric gas concentrations become a concern
of a wide range of scientists. The near-century delay between the
propounding of the theory and the widespread recognition of the
consequences for climate of continuing human activities implies a
recent shift in either the perspectives or in the interests of
researchers. Here we use citation indices to discern a major shift in
the focus of research into climatic change. Scientific findings in the
1970s and early 1980s are identified as a trigger to the development
of wider scientific concern over human-induced climatic warming, while
the period from 1988 to 1991 at first sight appears to represent a
major paradigm shift. However, it is suggested here that an inferred
change in scientific emphasis was caused primarily by a combination of
(1) new evidence from ocean and ice cores, particularly concerning the
relationship between past atmospheric gas concentrations and climatic
change; (2) the availability and application of new tools, notably a
new generation of General Circulation Models (GCMs); (3) attribution
of human causation for other environmental problems; (4) a changing
science research agenda, driven by political and funding
considerations; and (5) the contemporary recording of apparently
increased 'global' temperatures, which reversed a previously recorded
cooling trend. We caution that the pre-eminence and longevity of the
'global warming' thesis is vulnerable either to meteorological data
that do not fit with model scenarios, or to the rise or resurrection
of other notions on the primary forcing factors in climatic change. To
obtain a clear perspective on late-Holocene climatic change, it will
be necessary to evaluate palaeoclimate data that derive from a wide
range of complementary sources - sedimentological, biological,
archaeological and documentary - and to compare the magnitude, rate
and frequency of past climatic changes implied in those data with
recorded twentieth-century 'global' changes and projected
twenty-first-century scenarios.

So the basic idea of CO2 or other GHGs increasing global temperatures has
been around a long time
OTOH, there was no indication that CO2 was not fully sequestered until
measurements were made that indicated a progressive rise and the question
became. If CO2 increase can cause warming, and CO2 levels are increasing, is
there a consequent change in the global temperaure?
Note: Climate consequences? Why are the authors including predictions of
ACC, where Arehennius only calculated the GW?? Why is this given this way?
The issues of GW are totally separate form issues of consequent climate
change.

No. Arhennius only predicted what IS EXPECTED TO occur in a higher CO2
environment, based on thermodynamics. Interest was spurred by the discovery
that the CO2 levels WERE increasing. Something of a duh... not impressed by
this 'analysis'.
Note: Again emphasising the Arhennius theory in relationship to
'consequences for climate', which have nothing to do with his calculations
of thernal equilibrium.

The shift was from one of expecting but being unable to completely confirm
GW to one where the 'signal' was temtatively found, but the attribution ot
GHG emissions was being challenged. This led to later analysis for solar,
aerosol, and other forces. It was the slow process of weeding out the
irrelevant ideas and determining the extent of the effect of the relevant
ones that took time.

I fail to see what his 'suggestion' is pointing to. I DO note that this is
'opinion'..
Number 1 is of course just part of the puzzle. There was no direct link
between CO2 levels and temperature in the record, nor could the cause of the
CO2 increase be industrial so it begs the question, which came first, the
temperature change or the CO2 level changes. This is still somewhat
irrelevant to the GW issue.
Number 2: is correct, to the degree that GCMs gave us a tool to study the
one factor, how much warming to expect. The other use of GCMs was to try to
find common and consistent patterns in responses to GW on climate This last,
however, wasn't part of establishing GW.
Number 3: Huh? That change happened in the 60's and 70's with the rise of
the environmental movement and the cities choking in their own smog.
Number 4: The usual complete whooeyy.. More funds were allocated to the
study due to more interest in the consequences and the setting up of
intergovernmental bodies to study the situation. The ideas that it was
*driven* by politics instead of politics being *driven* by concern is the
usual ass backwards logic of the anti-science crowd.
Number 5 is, of course correct, as previously noted. There would be very
little work done on the GW issue if they had *failed* to find a warming.
"the most convincing place for a lie is between two truths". I see that this
has been expanded to include spin doctoring and whooey.

Science is always vulnerable to new evidence. The lack of such evidence
under intense and well funded scrutiny by some fairly competent scientists
means that a major change in the analysis is only 'theoretical'. Expect it
right after you see a brick building falling upstairs.

Now that is crap. The relevance of paleoclimatology to CO2 driven GW is
non-existent. Nor is the climate of the 55 milllion years ago relevant to an
earth with continents drifted into different positions, ice caps ( a recent
phenomenon ) and continents which break up equatorial currents ( closing of
the gap between North and South America for example. There is not comparable
*recent* change in CO2 levels is there? By recent I am talking about since
the closing of the continents and the buildup of the icecap, i.e. similar
geography to today.
Steve? How many times are you going to post this crap? Should I save this to
cut and paste a response?
Note: They make suggestions, but do not really have a leg to stand on in
science terms. The opinion is generally that the consensus started about
1992, showed up in the 1995 IPCC report and was stregthened by the 2000 IPCC
report which included endorsements from all major science academies, some in
defiance of their own government. As far as I can see, this 'op-ed' piece
has no solid basis in science and what they did include ( Arhennius )
confused his thermodynamics ( GW ) with 'climate change'. Very not
impressive.
DR. LAWRENCE PIERCE
Questions for global warming "experts":
1. Why should we base everything on data collected only in the
past 100 years? Wouldn't it be wiser to examine the data
collected from the ice layers in Greenland, which cover
THOUSANDS of years?
2. Some of this data is faulty, being collected from "heat
island" sources surrounded by cities of concrete and hot black
asphalt. IE, Los Angeles, Phoenix, Tucson, Dallas, etc. Such
places skew the data to fit the expectations of those whose
minds are already made up.
3. What are the ulterior motives behind this global warming
scare? Are these "scientists" being paid to promote this hype
for the chemical companies whose patents on certain products
are about to expire? Is it to paralyze the US economy so the
rest of the world can catch up? The fact is that most of the
world's worst pollution is coming from third world countries.
Mexico City has the worst air pollution of any city in the
world. China spews out hydrocarbons from its coal-fired
generators, without any pollution control devices affixed.
4. The biggest question concerns the proof of global warming,
I mean the actual physical effects which everyone can see.
Someone said that if only the ice in Greenland melted away,
the oceans of the world would rise 20 feet. Surely if global
warming was true and the glaciers were melting around the
world, this effect would be multiplied and we would see the
oceans rising all over the earth. But this is not happening.
The US Geological Survey crews still measure things as so
many feet above sea level, and that standard has not changed
at all in the past 200 years. And until it changes by at
least one foot, I'm not going to lose any sleep with any
"cry wolf" worries about climate change.

I got the information directly from www.heartland.org, not capitalism.com.
Heartland.org is very up front about where their funding comes from and they
claim about 1/3 is from corporate sponsers. In fact they publish a list of
their corporate sponsers on their website (which does include Exxon, but not
Enron). I don't want to get into a big arguement over which foundation is
spreading the truth and which is spreading propaganda....let's just say they
all have their own opinions. I think we can assume there are propaganda
machines on both sides of the issue. I'm hesitant to believe any of them
entirely, but I must admit to having a predisposition for not believing
doomsayers. I do work in the environmental field and hear exaggerations all
the time on from people speaking on environmental issues they really don't
understand (for example, everyone thinks asbestos is banned)
Nevertheless, I'm still stuck on the petition by the Oregon Institue of
Science and Medicine. They have broken their petition down into a sub-list
of 2,660 Physicist, Geophysicist, Climatologists, Meteorologist,
Oceanographser and Environmental Scientists
(http://www.oism.org/pproject/a_sci.htm) and another sub-list of over 5,000
Chemistry, Biology and Life Sciencers
(http://www.oism.org/pproject/b_sci.htm). Plus another 10,000 or so
"scientists". There has been several comments in this thread that this
petition is a fraud but no one has shown me why it is a fraud. Someone said
Scientific American did an expose on it, but I searched the Scientific
American website for past articles on Global Warming and couldn't find
anything specific to the petition. OISM also claims to have verified over
95% of the signatures and that the cost of the petition was paid for
entirely by private dontations and did not include any funding from sources
from within the coal, oil, natural gas or related fields
(http://www.oism.org/pproject/s33p357.htm). If this is all a big lie, I
would think the the pro-GW side would have a detailed examination of the lie
on a website somewhere. I would also think the people whose names appear on
the petition would stand up and speak the truth if they were somehow tricked
into signing it or the petition didn't represent their true opinion on the
subject.
I'm not trying to say GW isn't occuring as I'm no where near qualified to
make such a judgement. What I am trying to find out if there really is a
consesus in the scientific community that the the effects of GW, if left
unchecked, are going to lead to climatalogical disasters on a planetary
scale. The OISM petition would seem to dispute that claim.

Do you have any idea of how many people who might label themself
"scientists"? You could easily get this number of names on a petition
for example denying evolution, if you just wanted to spend enough
money on it.
Try to take a random sample in the list. Pick some people with unusual
names and search for them on the web. If they are scientists they should
almost certainly be found, together with some indication of their field
of expertise. That way you can decide for yourself how relevant they
are.
Even better. Go to a library and look in some scientific journals
such as Nature and Science and see what kind of articles they publish.
The truth in science is not determined by polls, but who has enough
facts to get his ideas published. It didn't matter that lots of
scientists didn't believe Einstein was right at first. He could show
how his theory made sense, they couldn't disprove it.
> There has been several comments in this thread that this

Call it a fraud or not, but it was clearly made to collect as many
signatories using whatever dirty tricks required. It was sent to
_a lot_ of people, by a former president of the NSA including an
article that was formatted to look as if it had been published in
their journal while in reality it is propagandistic junk, not fit
to publish anywhere. (Although supposedly it was eventually published
in the "journal of borderline science".
Of course you will get some people to sign just because they don't
know anything about the subject, but assume that Sietz does and
that the supposed review article gives a fair account of the science.
You will get another bunch to sign because they dislike the Kyoto
treaty for political reasons, regardless of what they think about
the science.

Scientists doesn't agree on _anything_. They make a living out of
questioning established truths. You want to find people who claim
gravity is a repulsive force, sure, I've met a couple. Does that
mean we don't have consensus on gravity being attractive? If you
want to be strict, we haven't, but usually the term is used to
indicate a large majority.

Big surprise. They admit it is a science, and like all scientific

fit.

"Hey, we want some of the money that goes to climate research too"
Well, they can have it. They are correct that understanding past
climate change is important to understand the present change. The
more climate data we have, the better we will be able to calibrate
our models of the climate.
This paper of yours does in no way contradict Roger's statement,
although some paleoclimatologists do seem unwilling to admit that
humans can change climate, or even study the subject well. It's
lika a historian who thinks everything that happened after the
fall of Rome (or whetever his subject) is irrelevant.

fraud. Again, all I'm trying to figure out is if there really truely is

I have a feeling that this has already been attempted by the opponents of
the petition. If the signers weren't reputable I'm sure it would be
plastered all over a pro GW web site somewhere. Especially since there have
been claims made against the expertise of the signers of the pro-GW
petition.

So they were all tricked into signing it. Ya, because those people with PHD
behind their name have a real problem with their reading comprehension
skills. The letter probably went something like this: "Hi Dr. So and So,
please read this article and then discard everything you already know about
GW and put your name and professional reputation on the line by making an

Maybe you're right and that is how it happened.

It is a fraud both in the 'junk-science' attached and in presenting the

Why? There is a consensus on GW. Read the www.ipcc.ch report. After that it
gets hairy.
There is some concensus on some of the risks based on GCM modelling in the
IPCC.
-Observed- <=> Confidence in Observed Changes:
-Projected- <=> Confidence in Projected changes:(a)
1: Higher maximum temperatures and more Very hot days over nearly all land
areas
-Observed-: Likely
-Projected-: Very likely
2: Higher minimum temperatures, fewer Very cold days and frost days over
nearly all land areas
-Observed-: Very likely
-Projected-: Very likely
3: Reduced diurnal temperature range over most land areas
-Observed-: Very likely
-Projected-: Very likely
4: Increase of heat index over land areas.
-Observed-: Likely over many areas
-Projected-: Very likely over most areas
5: More intense precipitation events.(b)
-Observed-: Likely over many N.A. mid-high latitude land areas.
-Projected-: Very likely over many areas.
6: Increased summer continental drying and associated risk of drought.
-Observed-: Likely in a few areas
-Projected-: Likely over most mid-latitude continental interiors. Possible
elsewhere.
7: Increase in tropical cyclone peak wind intensities.(c)
-Observed-: Not observed
-Projected-: Likely over some areas.
8: Increase in tropical cyclone mean and peak precipitation intensities.(c)
-Observed-: N/A
-Projected-: Likely over some areas.
a) For more details see Chapter 2 (observations) and Chapter 9, 10
(projections).
b) For other areas, there are either insufficient data or conflicting
analyses.
c) Past and future changes in tropical cyclone location and frequency are
uncertain.
And there is a general unease about the risk of triggering a major climate
event such as shutdown of the THC ( leading to a severe climate in Europe )
flooding from melting ice sheets ( Greenland ), severe storms, etc.
What level of damage do you require for 'disaster'?
> If there is a consensus then

Consensus comes with time. The climate scientists reached a consensus back
around 1992. There is no consensus among meteorologists, geologists,
dentists, or the general public. As pointed out, many of those whoi are said
to have signed it when it came out would not sign it now (having joined the
consensus), didn't sign it then, or signed it based on political
convictions, not science.
It remains a fraud in terms of illustrating a lack of consensus among
climate scientists. If you want to establish that consensus, take a survey
of published and peer reviewed literature and see how much takes GW as a
fact vs how many dispute it. No amount of politcial voting will establish an
'anti-consensus' on the science. To establish that you need to find data
which is inconsistent with the theory. Only one active scientist with
credentials and respect in the climate sciences is doing this, and Lindzen
has not come out with anything substantial yet.

So, exactly what scientific peer review was made and what science journal
was it published in? None??? I guess they didn't risk their scientific
reputation after all! That is based on published works and most ( amost
all?) of these people don't publish climate research anyway. Many that are
in the climate research field aren't pbulishing much now.

What 'pro GW petition'?? I know of none. The GW science is established by
thousands of individual researchers with peer reviewed articles, the work of
which was summarized in the IPCC reports.There was never any 'petition' is
establishing GW. There was science, not politics.

I can guarantee that there are at least 2660 PHd scientists in the world
that have very poor reading skills either due to senility, mental health
problems, or a lack of understanding of the climate field combined with a
strong political conviction leading to a opinionated blindness. The point is
that it was a political, not a peer reviewed science statement.

Nah, it really went.
"GW is utter bunkum and will cost you billions, ripped out of your
pocketbook by incompetent climate scientists and government tax grabbers
that jsut want to bankrupt America. Please stop this blatant attack on our

Double points if you work for coal, oil or gas companies... They employ a
lot of scientists of various field, few in climatology of course, but then
the petititon doesn't ask them to examine the established climate science
first, but presents a whole lot of distorions that may convince those not
familiar with the field.

I know enough to convince me that it is irrelevant. Obviously you are

You are right, it has been done. The result was a list of nobodys.
You can do a search on old messages in sci.environment to find that
and a lot of other discussions about this petition that has been
chopped to pieces on numerous occasions, but I figured it might
be more illuminating for you to do it yourself. After all, if someone
else picked names you can't really know if they were random or not,
can you?
Here is a link to another site with info about the OISM petition:

Most PhD:s don't know anything about climate science and we don't even
know how many of the people who signed have the claimed title anyway.
Just because you have a fancy title doesn't mean you are any less gullible
than anyone else, and only a small fraction of all that received this
petition signed it.
Now, some of the people did know what they signed, and my opinion of for
exemple Richard Lindzen dropped a lot when his name was found there.
Being critical of the common view on climate science is one thing, signing
a petition that argues that more CO2 is good for us something quite different.

So, if I understand your assertions we have two falsifiable
hypothesis:
#1. The Rise in the accumulation of CO2 in the atmosphere is due
primarily to human activities - principally burning fossil fuels.
#2. The apparent rise in the average temperature of the Earth is due
to rising CO2 levels.
--
#1 is falsifiable because a measured leveling off or decrease in CO2
levels not simultaneous with decreasing relevant human activities
would be a contradiction.
#2 is falsifiable because a subsequent cooling off not tied to
decreasing CO2 levels would be a contradiction.
--
These resilience of these hypothesis is what will eventually settle
the matter. For now, the skeptic in me is still skeptical about most
environmentalist claims.
A bit of "glass-house" advice: the rhetoric about simple or dishonest
minds does nothing to buttress your argument, nor to make an
unconvinced audience sympathetic to your viewpoints, nor does it
contribute to your personal credibility. It's a luxury that can be
dispensed with.

It is also shown to be true by using isotope analysis of the atmoshpere,
which shows that the apparent age of the carbon has increased (less
C14). This is to be expected as we add a lot of old carbon from fossil
fuels.
#1 is also obvious. Just measure the amount of CO2 emitted and the
amount of CO2 accumulating in the atmoshpere. You will find that the
problem that needs solving is why at the moment not all of the CO2 we
emit stays in the atmosphere.
> #2 is falsifiable because a subsequent cooling off not tied to

So how long does the warming have to go on before you are convinced?
That the theory hasn't yet been falsified doesn't prove it is
correct, and that will be true no matter how much climate change we
see.
Considering whether a theory is falsifiable is a good criterium
to decide whether or not it is science, but it doesn't say much
about whether it is a good description of reality. To do that one
has to look at all different theories that claims to describe
reality and chose the one that fits best and does so with the
least amount of special assumptions.
#1 would then have to be considered true simply because there is
no competing explanation with any shred of credibility. #2 would
have to be considered very likely because it is based on other
well established scientific theories and that there is no competing
theory that can explain the warming as well.

Being a sceptic is fine, but in situations with limited information
and where our actions have consequences we often can't wait until
all the evidence is in. Waiting is an action that has consequences
too.
The general who gets a report that the enemy is approaching may be
sceptical that the report is true, but he ignores it at his own
risk.

Which is proven by the study of the isotopic concentration of Carbon and

A fact which is accepted by the consensus of the worlds scientists.
But to be more clear. The consensus holds that at least the majority of
he observed warming of the earth is caused by the increase in CO2 levels.

All other things being equal.

Not necessarily. All other factors have to be accounted for.
It is a basic consequence of radiative physics that if you add an
insulating layer to a surface that is being heated, the surface will
increae it's temperature.

Then you are skeptical about most scientific claims as well. Even when
they are claimed by the consensus of the worlds scientists.
Quite pathetic.

Again, googling (we should just put the damn responses in

Really? I DID check the list out...I started with the As..and believe me
the number of those with any kind of qualifications in the field was almost
negative (exaggeration for effect). I have attached my first and last
post on the subject. I actually got up above 200, but the nature
of the results did not change.
\: Over 2600 of the signers are "physicists, geophysicists, climatologists,
: meteorologists, oceanographers, and environmental scientists who are
: especially well qualified to evaluate the effects of carbon dioxide on the
: Earth's atmosphere and climate." See http://www.oism.org/pproject/a_sci.htm
: for their signatures.
Andy, I looked at that list also. There were again, very few who
had any relevant qualifications. There were a lot of physicists
(easy to check via the APS membership book), nuclear, solid
state types etc. The number of people working in atmospheric
science or related fields was still very small. Couple of rock
hunters, etc.
Let me ask you. Pick any letter in the alphabet, pick any of the
lists (general, physicists, chemists, etc....) Tell us how many
of any contiguous number of signatures above 50 are experts in
any relevant area listing the area BTW, tell us also the name
of the list, and the name that you started at.

jh: Gee, when did you stop beating your wife. The argument above is
neither. It is no big surprise that in a large group (scientists) you
will find some who are guillible or adherents of any particular position,
no matter how far from the facts it is. Please note this is not a blind
adherence to any environmentalisht dogma, but a judgement on the
dogmatic and incorrect "paper" that accompanied the OISM petition.
The OISM petition was a scam. It strategy was the typical card forcing
strategy beloved by push pollers everywhere. It was organized by a
claque of partisans. The National Academy explicitly accused the
perpetrators of trying to mislead by formatting their "publication"
so that it gave the appearance of coming from the NAS. The ones
who fell for it were those not well informed about atmospheric
and climate science.
When the OISM list came out I traced about the first 200 names on the list
and the first 100 or so on the seperate list that claimed to be from
atmospheric scientists. The percentage of such was small, even on
the "specialists list" Someone suggested that I look at a number
of atmospheric scientists who had signed an earlier petition
(The Heidelberg Declaration I believe). Most had not signed
this one. Maybe they knew something you don't Here are the
first 50 names from the Heidelberg Declaration and whether they
signed the OISM petition or not.

Station, Antarctica. It is 420,000 years old. Mankind
has pushed CO2 levels to over 370 PPM, well beyond any
value found in this long period. See:
http://www.nature.com/cgi-taf/DynaPage.taf?file=/nature/journal/v399/n6735/full/399429a0_r.html&filetype=
The extremes to which we have pushed CO2 levels may have
created a whole new climate paradigm; the past may not be
a guide to the future climate.

Correction for the "heat island" effect is an old story:
1) It doesn't make much a difference in global temperature means.
2) It has been an excuse by denialists to exclude data points
that show warming.
3) Most of the reported warming occurs in high latitude
wilderness locations.
At this site you can create global temperature maps that correct
for or do not correct for the "heat island" effect:
http://www.giss.nasa.gov/data/update/gistemp/maps/
Start with these parameters to look at all the data,
correcting for any "urban heat island" effect:
GISS 2001 analysis, Hadl/Reyn_v2, trends, Annual (Jan-Dec),
1880, 2001, 1951, 1980, 1200 km.
Note the higher the northern latitude, the faster the warming.
Also note the lack of data in the southern hemisphere and the
Antarctic, in particular.
You should see that whether or not you correct for "heat island"
effect, the maps show a definite rise in global mean temperatures.

As I have said, "There is a lot more to global warming than
just rising sea levels." Sea level rise will be one of the
last global warming effects that we observe. The projected
sea level rise for the next 100 years is just 1 to 2 feet.
We will see other effects first: increased crop failures;
tropical diseases at higher latitudes; plant ecosystem die
offs; seasonal molds, fungi, and insect pests operating
year around; tropical weather systems, including hurricanes,
moving to higher latitudes; increased mortality from heat
stroke; . . .
Many of these things we have already seen. Alaskan forests
are being destroyed by beetles that survive the milder
winters in greater numbers, for example.

Conventional wisdom wasn't too concerned even well after the rising
trend was quantified. In that infamous 1970s-vintage peer-reviewed
particulate cooling article that young Stanford professor Stephan
Schneider and colleague published in Science, the authors asserted
pretty low maximum warming expected from doubled CO2 or somesuch. It
passed peer review without even a reference or other footnote on this
point.

Easy for you to say. Based on the experience of researchers like MIT
meteorologist Reginald Newell, these authors may have a hard time
avoiding retaliation from proposal reviewers with now long-vested
interest in the so-called "consensus" view. Dr. Newell's NSF funds
were cut back in 1989. His project, which involved analysis of sea
surface temperature data, was (according to Dr. Lindzen) not finding
any net warming trend for the last hundred years. "Reviewers suggested
that his results were dangerous to humanity", Lindzen reports.

Sure it contradicts Roger. Roger looks at abstracts and perceives a
shift. He draws a conclusion from this about what the shift means. The
abstract I posted indicates that the authors also perceive a shift.
Their abstract indicates that they draw quite different conclusions
about what the shift means. Roger has referred to his conclusions in
several posts besides this one. To the best of my recollection, he
believes that the shift represents quite a vindication of his alarm,
and quite a repudiation of those who do not share it.
> ... although some paleoclimatologists do seem unwilling to admit that
Steve Schulin
Historian Tom Fleming places significance on much different side of
the story: "Throughout the first half of the twentieth century, most
scientists did not think that increased carbon dioxide levels would
result in climate warming. Spectroscopic work by Knut Ångström,
Clemens Schaefer, and others led meteorologists to believe that water
vapor was controlling the infra-red heat budget and that doubling or
halving the amount of CO2 in the atmosphere would not appreciably
affect the amount of radiation actually absorbed by it."

I respectfully disagree. No major change is needed to cause the fad to

It sounds quite similar to what IPCC has said: "... a better

Roger Coppock
I have read the Chambers and Brain article. We do not disagree.
They report the beginning of the debate in 1988-1991 when the ratio of
papers crossed 50-50; I report the end in 1996-1997, when global warming
theory has an overwhelming 100 to 1 majority.

Proven? That's quite a strong word. "Indicated" or "strongly
indicated" I might accept. At least I would take the claim seriously.
Good scientific writing is also careful writing. But to call it
proven is to go beyond the certainty of the available evidence. The
Earth's climate has undergone warming before - even in historical
times. Given that these were also pre-industrial times and that their
causes are still not identified, more caution is called for. After
all - history could be repeating itself.

How good are these estimates? Of all of the proposals for CO2
reduction presently before us, how much would the CO2 levels be
reduced? Within what confidence limits? The answers I have heard
have varied wildly except that most agree that the present proposals
would barely make a dent in it.

What are you calling a fact? The historically recent rise in average
temperature of the Earth? (I agree - this fact is established beyond
reasonable doubt though there is some disagreement on its exact
magnitude.) Or that it is principally due to rising CO2 levels. (This
claim is plausible but not certain enough to be a fact.) Remember
that the Earth has experienced warming episodes in the historically
recent past that certainly are not due to industrial activities. Nor
has it to my knowledge been shown that CO2 levels rose at that time
due to some other circumstance.

I do not dispute that a body of opinion holds this to be true. It may
even be a "consensus" depending on how one scores that determination.
It is however the facts that must ultimately govern the outcome. I
have a problem with the claim that the number of scientists who
advocate this viewpoint, and moreover who believe the environmental
catastrophism so often advanced, is as overwhelming as portrayed.

All other things are NEVER truly equal. If caution is not to be
employed in making claims (what is proved vs. indicated; catastrophic
environmental consequences; etc.) then it should not be used in
formulating the falsifiable hypothesis.

Once again, selectively cautious language makes me suspicious. If the
appropriate level of caution is to be used is stating the falsifiable
part of the theory, a comparable level of caution should be used in
the claimed consequences.
Or to put it another way, if it is acknowledged that there are other
factors that are at least as important as the CO2 concentration (the
radiative output of the Sun for example), then it must also be
admitted that the concern over this one factor may be overblown and it
may not be the leading factor in rising temperatures.

But as you pointed out: "All other things being equal."
How good are out current models tracking increasing CO2 atmospheric
concentration to retained heat from the Sun? How much variance is
there between different models? I do not have a great deal of
confidence in the current predictive models. Is there any reason I
should?

I see GW as a firmly established scientific fact. So, the question is, can
warming of the atmosphere have effects on climate? The answer I think you
would get from a majority of relevant researchers is yes, in terms that the
hydrological cycle will be affected and the sea surface temperatures will
drive increased storm activity.
Now, The problem is not whether there will be changes. There are natural
changes as well. The question is how bad the additional changes are, where
they are, and if these simple changes are all of the story. I don't think
you will get much concensus on these questions.
The risks are there. We already have some ecological effects due to warmer
cool temperatures and lower winter die off of some pest species. The
question only becomes one of relative costs and since those are unknown, a
caution to minimize changes until we are sure of the science. Fools rush in
where angels fear to tread comes to mind. Are we fools?

Yup. It is a possible that we can data mine some helpful hints, but I don't
see it as all that applicable to generating predictions of climate change.
Too many details aren't the same today. Too many details with too much
uncertainty. Proxies are not the same as instrument data.
I'm not yet convinced that we can ever(in my lifetime at least) get a
detailed climate change prediction. No more than we can get a five day
forcast with 20% accuracy for the fifth day. What we can do is get some idea
of the general trends, and that will come from studying and improving GCMs,
and doing statistical analysis of trends from a better instrumented planet.
I'd call for something equivalent to the IGY, focussed on climatology and
meteorology, especially finding ways to 'fill in' the southern hemisphere a

Yes, Schneider did assume a very low value for the CO2 forcing. This
was pointed out to him right after the article was published and the
result was therefore considered not valid. The reason the paper is
infamous is that it is more or less unique, so that greenhouse sceptics
has to go back to this single flawed article over and over again.

Unlike the fact that the shift happened, what it "means" is just
speculation. They may speculate as much as they want and it won't
change the basic facts.

Throughout the first half of the century people besed their speculations
on limited spectroscopic data done in low pressure by physicists more
interested in determining the position of absorbtion lines than their
intensity. This made them ignore important phenomena such as pressure
broadening of absorbtion lines. At the same time people assumed, with
no real basis, that all extra CO2 would be sequestered.
Thus it seemed CO2 was unimportant for climate change and the field
was more or less ignored for a long time. Not until we got some data
indicating that there might be a problem, i.e., the CO2 concentration
was rising rapidly, did people start to study the subject in earnest,
and then it took some time to make reasonably sure what the warming
would be.
This may be interesting from a historical viewpoint, but it doesn't
say anything about whether the far more developed theories of today
are right or wrong.

In part that is recognized by everyone. But the basic laws of physics
are such that adding CO2 can only produce greater warming. The science
tells us that at the very least, most of the observed warming is due to
increasing levels of CO2. Some minor component could be natural. The IPCC
lists and quantifies those components.
Now since your claim is that all of the warming could be natural, and not
a result of higher levels of CO2, which laws of physics are you proposing
that science alter to make this possible?
I have asked denialists such as yourself this question literally dozens
of times, without answer.
Why do you think that is Ken?

Nearly perfect. Oil production is tracked to the barrel, and coal

Since proposals can be generated to match any expectaion your question
has no reasonable answer.
What can be said however, is that kyoto would not reduce Co2 levels.
Only the rate of Co2 emissions. And only reduce those to a level where
they still exceed the Biosphere's ability to absorb the Co2 being emitted.
This tells us that Kyoto is not only not draconian as denialists would
have us believe, but is positively benign compared to the actions that are
needed.
Denialists often childishly argue therefore that Kyoto should not be
considered because it is not a solution.
This is equivalent to arguing that one must never travel because the
first step is inadequate to complete the journey.

The facts are that CO2 levels are rising, and the globe is observed to be
warming. THis is what is expected as Co2 is added to the atmosphere. No
other credible explanations for the observed warming exist although some
minor component of the observed warming may be the result of factors other
than CO2.
The fact is that the laws of physics tell us that by adding Co2 to the
atmosphere, the atmosphere must warm.
Now which law/laws of physics are you suggesting we modify such that
additional CO2 has no such effect?

As to the the Environmentalist view being the consensus scientific
viewpoint, it is easily verified to be the case by simply visiting your
local university library and counting the number of pro and anti global
warming articles in the journals there.
You will be hard pressed to find any articles denying the reality of
global warming, or it's cause in scientific journals.
Why do you think that is Ken?
As for catastrophism, you won't find much of that in the journals either.
If you believe there is, then you have been flim flammed by the carbon
industry and it's paid shills.

Caution is not only employed by strongly indicated as a policy. The
caution is the no regrets emission reduction strategy that reduces
emissions, but does so in a manner that has alternate benefits not strictly
limited to Co2 reduction.
This is the policy that the Environmentalist and Scientific community
have been pressing for over the last decade or so.

As stated several times, there are no other factors that are at least as
important. CO2 is the greenhouse gas driving the show and it is the most
important.
Who has suggested otherwise? And on what scientific basis?

No, not in this case. Increasing levels of CO2 will always cause the
surface temperature to rise.
Other factors may also cause the earths surface temperature to rise or
fall as well. But as I have stated, all major factors are known,
estimated, and combined are a smaller role in the observed temperature
increase than Co2.

Your question is unclear. If you have seen the keeling curve you would
know that a simple linear model is sufficient to predict atmospheric Co2
levels for the next few decades since the trendline is very close to
linear, although superlinear.

On what scietific basis do you base your lack of confidence? Certainly if
you are to make any objective estimate on which you can set a confidence
level, you must have considered the models in detail and have a legitimate
complaint about their performance.
Can you tell us what analysis you have done, and what your complaints are
specifically?
Or is your lack of confidence coming from some other direction? Faith
perhaps? The consumption of propaganda? Psychic Vibrations?
Is there a reason why you should have faith in the existing models? Yes,
clearly. They all produce essentially the same general result.
Ken can you tell me of a single model that shows cooling as CO2 is added to
the atmosphere?

Well then, lets be very clear. The group in question is the set of world
scientists. There is general agreement, group solidarity, sentiment,
belief that the observed warming globe is a result of increased levels of
Co2 in the atmosphere.
I offer the following definition of the word "consensus" to guide you in
the comprehension of the above sentence.

Etymology: Latin, from consentire

2 : group solidarity in sentiment and belief
usage The phrase consensus of opinion, which is not actually redundant (see
sense 1a; the sense that takes the phrase is slightly older), has been so
often claimed to be a redundancy that many writers avoid it. You are safe
in using consensus alone when it is clear you mean consensus of opinion,
and most writers in fact do so.

Actually, it was pointed out to him before the paper was
published and acknowledged in a long footnote. Probably
by the referee. I think, if I were the editor, I would
have let it be published anyhow, with the footnote,
because of the importance of sulphate aerosol cooling
as a negative forcing. All in all a good example of
how the refereeing process should work, and that no
good dead goes unpunished.

How about established or proven beyond a reasonable doubt.
We are used to seeing all sorts of unreasonable ones, but
what the hey. A good place to start is
http://www.radix.net/~bobg/faqs/scq.CO2rise.html
and
http://www.radix.net/~bobg/faqs/scq.basics.html
which, although somewhat old are well written, available
to the layperson, and can give you the background you
need to participate in a discussion on climate change.
AFAIK, and I do follow the literature somewhat, no one
has usefully challenged the underlying research, although
in the meantime, it has been improved. The principal
advance has been a better understanding of CO2 sinks
which have held the increase down by a factor of two.
An interesting question is whether we are near saturating
any of those sinks.

Not really, although you might have to better acquaint

Now you are shifting the argument. The original argument was
about whether the observed (would you prefer proved?) rise
in CO2 in the atmosphere was due to human activities. Now
you are talking about warming of the climate. That is another
question due to anthropic activities. There the evidence
is weaker, but increasingly strong. This is quite a
normal tactic here, so join the crowd.

Well, do a google search on "carbon cycle". The answer is
that the estimates are improving. As to the second question,
that depends on how well you can predict future emission
scenerios. For example, the claim that the present proposal
(Kyoto) would bearly make a dent in CO2 levels rests on two
related supports. The first is that the developing nations
(principally India and China) would not join the control
regime in the future. Although that is a political question,
(they could elect Bush), given their behavior wrt the Montreal
Protocols to control CFC emissions, the presumption has to
be that they would join. The second is that their emissions
would grow strongly. Recent evidence of a significant decline
in Chinese CFC emissions puts strong doubts to that one. Both
China and India have an enormous amount of room in which to
improve the efficiency of their household and industrial
use of energy, and appear to be doing so. All in all, I
would question your assertion.

From the FAQ:
>From its preindustrial level of about 280 ppmv (parts per million
by volume) around the year 1800, atmospheric carbon dioxide rose to
315 ppmv in 1958 and to about 358 ppmv in 1994 [Battle] [C.Keeling]
[Schimel 94, p 43-44]. All the signs are that the CO2 rise is
human-made:
* Ice cores show that during the past 1000 years until about the year
1800, atmospheric CO2 was fairly stable at levels between 270 and
290 ppmv. The 1994 value of 358 ppmv is higher than any CO2 level
observed over the past 220,000 years. In the Vostok and Byrd ice
cores, CO2 does not exceed 300 ppmv. A more detailed record from
peat suggests a temporary peak of ~315 ppmv about 4,700 years ago,
but this needs further confirmation. [Figge, figure 3] [Schimel 94,
p 44-45] [White]
* The rise of atmospheric CO2 closely parallels the emissions history
from fossil fuels and land use changes [Schimel 94, p 46-47].
* The rise of airborne CO2 falls short of the human-made CO2 emissions.
Taken together, the ocean and the terrestrial vegetation and soils
must currently be a net sink of CO2 rather than a source [Melillo,
p 454] [Schimel 94, p 47, 55] [Schimel 95, p 79] [Siegenthaler].
* Most "new" CO2 comes from the Northern Hemisphere. Measurements
in Antarctica show that Southern Hemisphere CO2 level lags behind
by 1 to 2 years, which reflects the interhemispheric mixing time.
The ppmv-amount of the lag at a given time has increased according
to increasing anthropogenic CO2 emissions. [Schimel 94, p 43]
[Siegenthaler]
* Fossil fuels contain practically no carbon 14 (14C) and less carbon
13 (13C) than air. CO2 coming from fossil fuels should show up in
the trends of 13C and 14C. Indeed, the observed isotopic trends
fit CO2 emissions from fossil fuels. The trends are not compatible
with a dominant CO2 source in the terrestrial biosphere or in the
ocean. If you shun details, please skip the next two paragraphs.
* The unstable carbon isotope 14C or radiocarbon makes up for roughly
1 in 10**12 carbon atoms in earth's atmosphere. 14C has a half-life
of about 5700 years. The stock is replenished in the upper atmosphere
by a nuclear reaction involving cosmic rays and 14N [Butcher,
p 240-241]. Fossil fuels contain no 14C, as it decayed long ago.
Burning fossil fuels should lower the atmospheric 14C fraction (the
`Suess effect'). Indeed, atmospheric 14C, measured on tree rings,
dropped by 2 to 2.5 % from about 1850 to 1954, when nuclear bomb
tests started to inject 14C into the atmosphere [Butcher, p 256-257]
[Schimel 95, p 82]. This 14C decline cannot be explained by a CO2
source in the terrestrial vegetation or soils.
* The stable isotope 13C amounts to a bit over 1 % of earth's carbon,
almost 99 % is ordinary 12C [Butcher, p 240]. Fossil fuels contain
less 13C than air, because plants, which once produced the precursors
of the fossilized organic carbon compounds, prefer 12C over 13C in
photosynthesis (rather, they prefer CO2 which contains a 12C atom)
[Butcher, p 86]. Indeed, the 13C fractions in the atmosphere and
ocean surface waters declined over the past decades [Butcher, p 257]
[C.Keeling] [Quay] [Schimel 94, p 42]. This fits a fossil fuel CO2
source and argues against a dominant oceanic CO2 source. Oceanic
carbon has a trifle more 13C than atmospheric carbon, but 13CO2 is
heavier and less volatile than 12CO2, thus CO2 degassed from the
ocean has a 13C fraction close to that of atmospheric CO2 [Butcher,
p 86] [Heimann]. How then should an oceanic CO2 source cause
a simultaneous drop of 13C in both the atmosphere and ocean ?
Overall, a natural disturbance causing the recent CO2 rise is
extremely unlikely.

I don't think he was claiming ALL the warming was necessarily from natural
causes. I also don't think you would conclude that it is definately ALL
from human activity. So let's assume GW is occuring due in some part from
natural causes or natural fluctuations and also some part from human
actions. If we can agree on that assumption then several important
questions could be asked.
For instance...at what ratio (natual vs. human caused warming) would it make
political and financial sense to even bother trying to alter human
activities to stop the warming? Also, with what scientific certaintity can
the ratio be determined? Also, with what scientific certainty can the
results of the warming be determined? Also, what percentage of the GDP
should be used to try and correct the situation?
For example (just throwing these numbers out there), let's just say we agree
that 50% of the warming is caused by human activity and 50% is from natural
fluctuations, lets also say we're 25% certain of that ratio and 25% certain
that there will be catastrophic results from the warming. There are still
going to be disagreements on how much money, if any, should be spent to
change human activities.
Just out of curiosity, what would everyone's estimates be for A) ratio of
warming caused by humans vs. natural causes; B) How certain are you of that
ratio; and C) How certain are you that there will be catastrophic results
if the warming continues at the current rate? D) What percentage of the
GDP should be used (assuming that this will cost money)? Wondering if
anyone would answer 100% to all three.

My problem is that unlike theories about the Universe's expansion or
the mass of neutrinos - this one is being used as a basis for
substantial policy proposals that carry consequence.
All of the proposals being made for "solving the problem" either make
too small a dent in the CO2 levels to matter (even assuming the
underlying models are accurate) or they carry such dire economic
consequences (or both) that I believe that we had better be damn sure
we know what we are doing.
The Earth has undergone warming (and subsequent cooling) in the
historic past unconnected with industrial activity. (Greenland once
warmed for a few centuries long enough to be briefly settled by
Vikings before the climate turned cold again.) Given this knowledge -
that climate changes happen naturally for reasons not well understood
- it would behoove us to be careful.
After all major surprises in a relatively new field is nothing
unexpected. For example, we've just learned that the rate of the
universe's expansion is INCREASING. Since Newton we have assumed that
gravity is the dominant force on the largest scales and since Hubble
we have known that the Universe is expanding. It was always believed
however that the expansion was slowing down due to mutual
gravitational attraction. Apparently, it isn't. Fortunately, this
has no public policy implications.
The large scale study of the Earth's environment is also a new field.

Agreed. But we also bear in mind that there is always a "none of the
above" possibility, especially in a new field. There is no guarantee
that we have thought of everything or even the most important things.
There is also no guarantee that the metrics that are being used are
not faulty. They should improve with time provided open inquiry is
being aggressively pursued. With the politicization of this issue, I
have my doubts.

I disagree. (See above.) To establish that #1 is true it is also
necessary to show that no competing explanation is likely possible –
and that alternative factors are not significant. For example, if
some natural or human-induced variation has occurred in the rate at
which atmospheric CO2 is absorbed and removed from the atmosphere,
this could be the principal cause of elevated CO2 levels. That could
implicate everything from deforestation to wildfires. In this case,
while the presence of isotopic C14 levels could be adequately
explained by industrial activity, its level in the atmosphere might
owe more to its tardy removal or premature reintroduction than to its
overproduction.

Doing the wrong thing – or placing a new scientific discipline in
disrepute because it is used to issue premature and alarmist
recommendations – also carries consequences.
To date, all public proposals that have been advanced to deal with CO2
barely make a dent in the CO2 level even assuming they are strictly
followed (a doubtful proposition at best). When the formulation of
public policy comes into play, the endeavor becomes more than
scientific in nature. It becomes more of an exercise in engineering
and persuasion.
As an exercise in engineering – economic analysis is at least as
important as the underlying environmental science. It may well be
that the economic costs are simply too great even if the problem is
real. In that case, attempts at CO2 reduction may be doomed to
failure and may impoverish the world's economies to the point of
making them less able to deal with the consequences when they do
happen.
As I see it, the question is: What makes more economic sense –
avoiding the consequences or dealing with them when they occur? I do
not pretend to know. At the present time environmentalists shouldn't
either.
At present we do not have enough information to make an informed
decision on this question. And making the WRONG decision (either way)
definitely carries consequences.

He also dispatches his entire force into ambushes at even greater
risk. I am not advocating that environmental concerns be ignored. I
am not even advocating that they be studied ad-nauseam so as to induce
analysis paralysis.
I am however pointing out that nothing we know how to or are likely to
do over the next decade is going to make much of a dent in the
atmospheric CO2 levels. That is about how long I estimate it will
take for responsible, aggressive scientific investigation to shed
enough light on the issues I raised earlier so as to permit rational
and effective policy decisions to be made. It may turn out that doing
nothing is indeed the best course.
In his autobiography, "Failure is not an Option" Gene Krantz wrote
about his early days at NASA under Chris Kraft. One day, a failed
rocket launch had left a fully fueled booster sitting precariously on
the launch pad, locks disengaged, umbilicals unplugged, and the
parachute unhelpfully deployed. A good gust of wind would be all it
would take to knock the rocket over and trigger a destructive
explosion. In the immediate frantic minutes after the near disaster,
flight controllers and engineers were excitedly debating what to do –
in particular how could this rocket be safely defueled. A number of
suggestions were made that Krantz wrote didn't even sound like a good
idea to a new kid like him on the block like him. (e.g. shooting
holes in the side rocket so that the propellant could evaporate.) The
situation was too precarious to allow any support staff near the
rocket while it was still fueled.
Finally after the staff settled down, a calm voice arose from the
group and recommended that they allow the onboard battery to discharge
(something it would do on its own). This would cause the fueling
valves to revert to their open, inactive position. This would allow
the fuel to evaporate away at ambient temperature. A few quick back
of the envelope calculations indicated that this would take the
remainder of the day and that by the next morning, it would be safe to
approach the rocket.
Krantz wrote: I learned my first rule of flight control – when you
don't know what to do, then do NOTHING. Acting in the dark he
reasoned was more likely to make things worse, not better.
We would be likewise well advised. Otherwise we may be wasting
substantial resources on a diversionary attack.

There will be consequences to unchecked GW and ACC, so it is not a choice
between no problem and taking action.
Beyond the known consequences ( mostly in hydrological cycles, causing
drought or flood ) there are the possibility of critical events causing
disasterous changes, such as shutdown of the THC or melting of the Greenland
Ice Sheet, or X( the unknown big surprise).
The consequences of climate change due to GW are fairly well established.
The consequences of CO2 emission reductions are very hard to calculate since
some initiatives will have net benefit and others will be complete frauds.
The proper course of action is to take measured steps with due dilligence to
promote the best of these initiatives and develop the basis for new
inititiatives under careful scrutiny.
If this is an objection to Kyoto, remember that Kyoto just sets *targets*.
It does not restrict methods.

Yes, it has consequences, but it has consequences either way. You
seem to think that it is safe to wait and do nothing until we have
more data. Nothing is further from the truth. Doing nothing in this
case continuing to emit large amounts of gasses that is very likely
to have large consequences for the climate for many centuries ahead.

While I'd say we had better be damn sure what we are doing before
we continue to emit gasses with undersirable properties. Even doing
a little, which can even be done at negative cost, will buy us some
more time to get more data, and it will pave the ground for more
drastic cuts further ahead.

You are right that we should be careful, but not the way you think.
The natural fluctuations show that the climate is not as stable as
we would wish, and thus that any perturbation we make may interact
and be amplified. The potential halting of the Gulf stream is an
example of such an amplification.

I wouldn't bet on it. This value has been bouncing up and down
a long time, and I'm far from sure that the current data will
survive the test of time.

Just remember that errors can go both ways. The current estimates
are the best we can do at the moment and it is just as likely
they are too optimistic as too pessimistic. I'd even say it is
more likely they are too optimistic. Since just about any climate
change is for the worse there is only one state we want and a
large number of undesirable ones. It is unlikely that errors
will conspire to ensure that the climate remains constant. It is
much more likely that they will just mean that they will cause
the climate to change some other way than predicted. Ending up
in a desert isn't that much better than being flooded.

Why do you call them environmental scientists rather than climatologists
or any other more neutral term? You seem to think they all have the same
political agenda. If you consider people like Lindzen, Christy, Singer,
Seitz etc they have been looking very hard for any kind of evidence that
the warming is not anthropogenic, but so far their results haven't been
that impressive.

Not warning for a threat that turns out to be true also carries
consequences. Not only will we have changed the climate of Earth,
but the trust in science and technology will have taken another
hit, and we are likely to see a significant backlash.
You have to compare the probability and the risks of erring in
either direction. As far as I see it erring on the side of caution
carries a lot less risks.

It is possible to reduce emissions as seen from where I live:
http://cdiac.esd.ornl.gov/trends/emis/swe.htm
We switched from oil to nuclear power and also made efforts to reduce
energy consumption. This was a huge reduction compared to what is so
controverial in Kyoto. Admittedly we will find it slightly harder to
continue downwards, but that is because we are already far below most
other industrialized countries and because of a political resistance
to nuclear power.

Just add a tax to carbon emissions and let people scream. They'll
soon tire and start inventing ways of reducing their now expensive
emissions.

That kind of analysis has been done and shows that considerable
reductions can be done with negligible cost. You just have to step
on some toes, because some people profit a lot from the current
situation where you can pollute for free.

You may pretend that you don't make a decision, but that is in
itself a decision. If you wake up in the middle of the night
and smell smoke, it may be coming from some distant fire, but it
may also come from your own house. If you remain in bed waiting
for further evidence it may very well be too late to get out if
it was your house that was on fire.

No matter when we start, nothing much will happen the first several
years. It takes time to change the course of a supertanker. If
we don't do anything now it will just be that much harder to do
something in a decade, not to mention that there will still be
people who claim that in another decade there will be even more
evidence available so you can make an even better plan.
Doing a little today may mean that we don't build a new coal plant.
Delaying the decision may mean that we first build the plant and
then have to close it and crash build something else instead. Which
do you think is cheapest?

This is sometimes a good idea. On the other hand as I've already
pointed out, releasing lots of CO2 in the atmosphere isn't really
doing nothing. We also already have a lot of information, you are
just too much of a perfectionist. We will _never_ have access to
perfect information.

I know this is kinda of beside the point, but in 10 or 20 years
environmentalists will still have the exact same complaints about 1.6 metric
tons of carbon per capita as they did 20 years ago when it was 3
tons/capita. Lets say that in 50 years you get it down to 0.2 tons per
capita. Hey wouldn't that be wonderful? Nope, environmentalists will STILL
make the same arguements that it is way to much and the world is going to
end if nothing is done about it. It never ends.

There is a trade-off between human consumption and room for other creatures,
and there will always be some people who claim that we are grabbing too much
for ourselves. What will change is that the number of people who wants
further reductions will decrease as the perceived damage goes down.
Note that here I'm talking about people wanting to protect the environment
as opposed to just protecting humans, because those are who I would call
environmentalists. At the moment you don't have to be an environmentalist
to want to reduce CO2 emissions, being a humanitarian is just as fine.
Come back with your complaint when we have reduced our emissions to a
point where it is a matter of protecting the environment rather than
ourselvelves. Then we can discuss it further.

It isn't a choice between natural change and anthropogenic change. The
science has established that it is a combination. However, the other factors
are not cummulative, so the result is that GHG forcing will dominate the
future.
Of course, defending the science is not a matter of 'advocacy'.

Rogers motive seems to be to defend the science from the attacks of those
who are ignorant or do not wish to know the facts.

Since Roger stops after defending the science, there is no evidence of an
*ulterior* motive.

Nothing was said about advocacy for the children or grandchildren. Can you
not distinguish between science and your own agenda?

doing

Then you agree that the science establishes a reason for alarm? Would it be
less alarming if it *were* natural? Man sometimes has to fight nature for
his own purposes. Would the reasoning change if GW was natural and we were
headed for a venuslike atmosphere? Nothing really says that 'natural' is
beneficial. Many natural things are not beneficial and we spend billions
combating them. The whole 'natural' bushwah is an attempt to say we are not
responsible. Nobody is holding us responsible. There is no court of last
appeal for climate change. It just is. The question is only whether we are
happy with the change ( whether manmade or natural ) and are prepared to do
anything about it ( whether manmade or natural ).

You suspicions about conspiracies does not change the science. No more than

old to be involved in the 1897 Indiana bill, I hope ) The science has been
given very careful scrutiny and no flaws have been found. Let us know when
you find a link between the Republican Party and the law of gravity... At
that time, the effect of politics on scientific reality will have to be
re-examined.

If we all reduced to the 1990 levels of CO2 emissions, and cut methane,
nitrogen oxides, CFCs, etc., even more drastically, we could make a
good dent.
Or it may be underestimated. The current estimate is the best science
can do, and it's alarming.

As little as 5 years ago, so was I. But the data keeps coming in, and
it's all supporting warming occurring, mostly due to human activities.

Heck, we can't "estimate" what a single electron is going to do, but we
use quantum theory in everything from fusion (the sun) to computers.
You don't have to have 100% certainty in science to take action, you
know. (In fact, with quantum mechanics at one end and chaos theory at
the other, you'll seldom have it.)

But not chemistry. CO2 absorbs heat just as it has been known to do
for some time. Absorbed heat raised temperatures, just as it has been
known to do for some time (even back when it was called "caloric").

So how do you explain every combustion, producing CO2, yet this not
increasing the atmospheric CO2? Is the added CO2 being converted to
gold or something?
That's what the nay-sayers and industry shills said about CFCs.

The saturation of the 15-micrometer absorption band was key to their
calculations. The main difference between their estimate and best
previous estimate was, as best I can tell, their updated absorption
coefficients. I've searched the Science archives and seen
near-contemporaneous criticisms of the particulate cooling part of the
paper, and I would attempt to find and read with interest any accounts
that refer to the invalidating criticisms you mention regarding the
CO2 sensitivity, and would very much appreciate any recollection folks
may have to help track down any such references.

The paper is very interesting in many ways. You don't see too many
exclamation marks in journal articles, so lines like "If sustained
over a period of several years, such a temperature decrease could be
sufficient to trigger an ice age!" are pretty memorable. The fact that
Dr. Schneider was so (!) in warning about particulate-induced cooling
makes for quite reasonable comparison with his more recent warnings
about enhanced greenhouse warming.

I don't think most would say that either, but that's what I keep getting
attacked for claiming. The question of whether or not GW is occuring is
different from the question of how bad are the consequences.
Here is what the petition states "There is no convincing scientific evidence
that human release of carbon dioxide, methane, or other greenhouse gasses is
causing or will, in the foreseeable future, cause catastrophic heating of
the Earth's atmosphere and disruption of the Earth's climate." Notice the
word catastrophic because I think that is important. Take out the work
catastrophic and you probably lose 75% of the signers.

Yes, I found a only a reference to a couple of obviously faked names on the
petition, which OISM also openly admits to and having removed them. Again,
I haven't see the Scientific American study, may have to try some more to
find it.
I'm taking the information at OISM at face value. I guess it is possible
OISM is just making the whole thing up, but they claim to have confirmed 95%
of the names, including what scientific field they are in. The list is
divided into the different expertise levels. For example they specifically
list out 2,660 physicists, geophysicists, climatologists, meteorologists,
oceanographers, and environmental scientists as well as another 5,017
scientists whose fields of specialization in chemistry, biochemistry,
biology, and other life sciences. http://www.oism.org/pproject/a_sci.htm or

Google still has it cached at:

The relevant excerpt is:
"Scientific American took a random sample of 30 of the 1,400 signatories
claiming to hold a Ph.D. in a climate-related science. Of the 26 we were
able to identify in various databases, 11 said they still agreed with the
petition--one was an active climate researcher, two others had relevant
expertise, and eight signed based on an informal evaluation. Six said
they would not sign the petition today, three did not remember any such
petition, one had died, and five did not answer repeated messages. Crudely
extrapolating, the petition supporters include a core of about 200 climate
researchers--a respectable number, though rather a small fraction of
the climatological community."

As pointed out by Connolley and Halpern, the fact that it was a
low estimate was mentioned in a footnote to the paper, so I was
wrong. (Reminds me of an old book by Eddington I came upon where
he discussed the age of the universe and there was a footnote
that there was this chap Hubble who had a completely different
view than everyone else)

You don't know if if was Rasool or Schneider who put in the exclamation
mark. Rasool was the first author and thus primarily responsible for
the paper.
Anyway, all it would indicate is that Scheider unlike the "ivory tower"
scientist was concerned about the importance of his research to society
even at this point. Hardly surprising given his later performance.
The authors did exactly what responsible scientists should do: they
found a potential problem so they published an article in the scientific
press to see if the result could be confirmed. It turned it it wasn't,
and for other reasons the amount of aerosols emitted never reached the
feared values so this particular problem was written off.
I fear that in the current politicised environment such a paper might
not be published out of fear that it could come back and haunt the
authors. Scientists are supposed to be allowed to publish results
that are wrong occasionally without someone digging them up decades
after the fact and using them in a smear campaign!

You folks are absolutely correct that footnote 12 discusses the
authors' statement that "From our calculation, a doubling of CO2
produces a tropospheric temperature change of 0.8 degrees K." And it's
true that my recollection of the article could have been better. But
my comments were honestly offered, and my use of the phrase "doubled
CO2 or somesuch" was an expression of my awareness that my
recollection was not precise. Looking at the paper again, I think
Connolley's comment that it's "clear" that I hadn't even read the
paper is quite unjustified. Where's the reference or note related to
such statements as "...as more CO2 is added to the atmosphere, the
_rate_ of temperature increase is proportionally less and less, and
the increase eventually levels off. Even for an increase in CO2 by a
factor of 10, the temperature increase does not exceed 2.5K.
Therefore, the runaway greenhouse effect does not occur because the
15-micrometer CO2 band, which is the main source of absorption,
'saturates,' and the addition of more CO2 does not substantially
increase the infrared opacity of the atmosphere..."? That's the
"somesuch" to which I referred when I wrote:
"Conventional wisdom wasn't too concerned even well after the rising
trend was quantified. In that infamous 1970s-vintage peer-reviewed
particulate cooling article that young Stanford professor Stephan
Schneider and colleague published in Science, the authors asserted
pretty low maximum warming expected from doubled CO2 or somesuch. It
passed peer review without even a reference or other footnote on this
point."
I was not castigating the authors, nor the peer reviewers. I was
noting that it was not the ability to measure CO2 increase that likely
sparked concern, as a previous poster had suggested.

A letter from Paul Gast of Argonne Lab was published a couple of
months later (Science 173:982-983, Septembe 16, 1971). He points to an
error in the particulate cooling analysis that reduces the 3.5 C
cooling estimate to 1.0 C. I've not seen reply to this criticism,
although there may have been one that my search of Science archives
did not reveal. A few months later, in response to criticism in letter
by Charlson, Harrison and Witt (Science 175:95-96, January 7, 1972),
Rasool and Schneider emphasize the major weakness associated with
trying to represent dynamic atmosphere with static model. There's no
hint of their original (!) in the tone of their quite reasonable
discussion here of their "instructive and necessary first step".

I don't think the Brain and Chambers recommendation to obtain a clear
perspective, nor the IPCC recommendation to reliably estimate past and
future trends, are so preposterous. In fact, in sounds downright
reasonable compared to demands that CO2 emissions and many related
activities be controlled by international planners. There are
significant uncertainties related to virtually every scientific and
policy aspect of the climate change debate, and that includes the
subject of whether enhanced greenhouse effect will be harmful or
beneficial.

What makes you think there is a fixed line?
Fuel economy is a function of environmental impact. If there were
1/100th the cars on the road that there are today, fuel efficiency
standards for cars could be far lower.
Ultimately what matters is the total impact on the environment.
It's rather shocking that you wouldn't understand such an obvious thing.

Actually, ultimately what matters is the PERCEIVED impact to the environment
and/or human health. If there were 1/100th of the cars on the road with the
current emission standards there would STILL be just as many
environmentalists complaining. They would just be complaining about a 0.001
% increase in the rates of lung cancer instead of a 0.1% increase in the
rate of lung cancer. The newspaper headlines would still read "Auto
Emissions Result In Increase Risk of Lung Cancer!!". The environmentalists
would STILL get in their gas guzzeling vans to drive halfway across the
state to protest somewhere, because that is what they do.

It must have been the other way. Scheider graduated from
Columbia in 1971, and his work was done at GISS (which
makes sense, even for a mechanical engineer). In other
words, Schneider is probably the junior author. Rasool in
his own right is a well known and respected scientist.
Moreover Schneider joined Stanford in the early 90s. Now
ordinarily all this would make little difference, but there
is a concentrated effort to distort this paper and describe
it from secondary sources. In short there is a track record
here.

Global Warming Coming to Bay Area, Scientists Say
By Sue Kwon
If you think it's hot now, scientists expect global warming (news -
web sites) to bring average temperatures in the Bay Area up by four
degrees in the next 50 years.
Researchers at Lawrence Livermore Laboratory have pictures to prove
it. The images look a lot like satellite maps, but they are new
climate simulations created by a supercomputer. The models tell
researchers that the global and Bay Area climate is changing.
"We can predict the future weather within three to four days," said
Dr. David Nowak, with the Atmospheric Science Division. "With the
global climate, we can predict the climate in 10, 20, 50 years into
the future."
Research shows global warming will push average temperatures up by
about four degrees over the next 50 years, and there's another future
change in the weather. Scientists at the labs say we will see a
significant change in precipitation in the next 50 to 100 years --
with more rain, and less snow, because of higher temperatures.
"A significant impact on the snow pack has an effect, because water
resource managers use snow pack as a reservoir," said Dr. Philip
Duffy.
The lab has turned this information over to state water officials,
while the scientists continue to create more long-range models using
the world's fastest computer.
"If you think of it as laptops, it's taking 8000 laptops and packing
them together in one room, and making them run on the same format at
the same time," Nowak said.
It's normally used to simulate nuclear weapons tests. But it can also
take weather data from around the globe and crunch 12 trillion numbers
per second to calculate and create the most detailed global climate
simulations available. That means that images now have six times the
resolution that they did before, helping scientists see the future of
our climate more clearly.

do you always convict without evidence on the basis of personal expection
and ideological stereotyping?
Of couse you do. Who needs justice when racism will do.
Forkboy2
more stringent than 30 years ago, the environmentalists still have many of
the exact same complaints as then and then some? All I'm saying is that in
30 more years the regulations will be that much more stringent and, BASED ON
PAST HISTORY, the environmentalists will have the same complaints.
And what exactly does racism have to do with any of this?

I can't quite see why you've repeated your fundamental error here. The
fact is that it *was* commented on (ie the low max warming) in a
footnote, in direct contradiction to what you posted.

I think that R+S were remiss in not commenting on the weaknesses of their
model in the original article. In fact they do this in footnote 14
to some extent, but also make the bizarre statement "...it is reasonable
to use these methods to investigate the effect of small changes in a
single variable..." - which is very odd, since doubling (let alone
8-iplying) a variable hardly counts as a small change.

If you're drowning in a shark-infested sea, you probably aren't too
concerned with a toothache. Once you're out of the sea, you view the
toothache as something to complain about.

Of course the key here is that they are talking about the
RATE of temperature change, not the temperature change, and
you forgot to point out that this entire discussion
(and the footnote) starts by pointing to Figure 1, which
shows NOT that the temperature does not change as pCO2
increases, but that the variation is logarithmic. Therefore,
anyone who was reading the paper and not quoting it out of
context, would realize that what R&S meant was that the
tropospheric temperature change would be sublinear with pCO2,
WHICH WAS THE PREDICTION OF THEIR MODEL, and yes, a scaling
factor of 3 for CO2 sensitivity is important.
SNIP....

The authors' affiliation was GISS in the Science paper and
Schneider was too young to be a professor. He had a NAS-NRS
resident research associate during the period in which the
work was done. He also got his Ph.D. from Columbia in 71.
See the last footnote. Rasool was probably staff then,
and they thank Jim Hansen for help. Read the paper..

Gee, that was flat out WRONG.

There certainly were a number of papers at that time on the
issue of pCO2 increase including some that were referenced in
R&S. Without asking the authors, this can not really
be answered, but as I recall there was a general awareness
that pCO2 was substantially increasing even in the early
1970s. Keeling's work at Mauna Loa was not a secret.

Boy, wonderful dissembling here Steve. Gast did not criticize
the calculation of climate sensitivity to aerosols, he said
that R&S had overestimated the probable change in aerosol
loading by a factor of two, thus the difference. In a
letter appearing directly below Gast's Barrett reports
a similar calculation to R&S which found that an increase
of aerosol loading by a factor of 5 would change the surface
temp by -3 C (as opposed to R&S's -3.5C for a factor of 4).
Barrett says that his results are in good agreement with R&S.
As to Gast's point, sulphate aerosol loading did only
increase by a factor of two, but neither Gast or R&S
considered indirect aerosol forcings which amplify
the direct forcing, or the subsequent successful
limitation of sulphate aerosol emissions in response
to the acid rain phenominon.

Again, you leave omit the major point. As R&S state:
"As with all models it is clear that the conclusions drawn
from the model of R&S are critically dependent upon the
assumptions in the model. The problem, therefore, is
how closely the model represents the reality.
One of the basic assumption in our model questioned by
Charlson, et al., is that the aerosol layer is
concentrated primarily below the average cloud layer
(3) and that therefore, its presence affects only the
albedo of the cloudless part of the earth., .......
Charlson, et al. will be making a valid point if they
can show quantitatively that the small amount of aerosol
ABOVE the cloudy part of the atmosphere could DECREASE
the aldebo of the cloudy half of the earth so as to
offset the increase in the aldebo of the cloudless
half. In the absence of such a quantitative estimate of
this effect, no comments can be made on their criticism
of our assuptions.
(3) This assumption is based on Fig 2 from L. Elterman, in
which an exponential scale height of 1.2 km is given for
the variation in the number of aerosol particles with
altitude in the atmosphere. For this reason and also
because most man made sources of particles are located
near the earth's surface, we felt that it was necessary
to assume that atmospheric aerosols (and especially
increases in aerosol concentrations related to man's
activities) were primarily concentrated below the
average cloud top levels."
They go on to point out that they had specifically
commented on the issue of static models in footnote
14 of the original paper. So much for changing tone.

Exactly, and when when the toothache goes away, you complain about something
else. The difference with extreme environmentalism is that they would say
"There's sharks in the water, if we don't do something about it the world is
going to end (or some other dire consequece)". Then when the sharks are
gone, they would say "We all have a toothaches, if we don't do something
about it something very bad is going to happen to all of us". Then when the
toothache goes away they would find something else.

>Bogus,
Do not dismiss my information from the public with your false accusation.
I report on the subject of invisible personnel and life control surveillance
station/system, which includes mind control technology, invisibility technology
& illness/death inducing technology.
My reports are written to the best of my knowledge based on facts found in:
*de-classified CIA documents
*technical papers written by mind control researchers
*United States Patent 3,951,134 - an EM mind machine (Apparatus and method
for remotely monitoring and altering brain waves)
*United States Patent 4,877,027 - a microwave voice device (Hearing system)
*reports from government think tanks
*books authored by civilian scientists,
*news articles
*reported victims cases
*Invisible personnel information originally came from former Taiwan President
Chiang Kai-Shek.
The CIA's death inducing research (induced heart-attack & cancer) in 1950s
(Washington Post report on 4/2/1979) and the classified cerebral hemorrhage
inducing techniques research (code-name operation Pandora from 1965-70) of
Defense Advanced Projects Research Agency are the solid evidences to prove
that the involved officers have developed illness/death inducing techniques.
Also, both declassified research prove that invisible personnel exist and
secretly used to induce illness/death on their targets since 1950s.
Why?
As an insider's note in the CIA death inducing research in 1950s, it
indicated his concern about the vulnerability of US leaders to
assassination by "natural causes." The note proves only invisible personnel
can use the illness/death techniques to induce a target to have heart-attack,
or cerebral hemorrhage anytime, anywhere and APPEAR as natural causes
Why? Because by using psy (nonlethal) weapon, these invisible personnel's
murders always leave no evidence of an intruder, a struggle and no signs of
external injury on victims' bodies.
Where are the invisible personnel from?
According to inside information from former Taiwan President Chiang Kai-Shek,
the invisibility technology of Philadelphia Experiment tested in WWII has been
developed successfully to use on human after WWII by US Navy. After using
invisibility technology on the personnel and their equipment, they will become
invisible, tiny and can levitate. Since the invisible personnel & equipment will
become tiny (like small ant size), the invisibility technology cannot be used in
military for combat. Thus, it has been changed to use in surveillance system. In
1950s, this invisibility technology has been transferred to Taiwan's surveillance
system. Based on the characteristic of levitation of invisibility technology and
wearing a propulsion device on back, every invisible personnel can move as a
small flying ant /(with carried equipment such as weapons & mind machine).
Thus, the tiny invisible personnel can gently fly onto people's head to control
people's brain/bodily functions and land on a target's body (near any organ) to
induce illness/death without most victims' knowledge ((But so far, they still
cannot explain why humans become tiny in the invisible electromagnetic field
-invisibility technology see details on Part II-A1 of my website). Since their
chief goal was to hasten Chiang Ching-Kuo's rise to power, Taiwan invisible
personnel kept all important persons (including the President Chiang Kai-Shek)
under surveillance and unlawful life control. Taiwan's invisible personnel of
surveillance station/system also secretly induce illness/death on some victims who
opposed Chiang Ching-Kuo for succeeding Chiang Kai-Shek as President from victims'
homes/offices, cars, etc. (e.g. former Vice President Chang Chen -see details on
Part II-F1 of my website).
The deaths of invisible personnel's victims will always appear as the result of
natural causes. Why? and how can these murder victims be mistakenly
believed to have died of natural causes? It happened because following three
reasons:
(a). Invisible personnel's murders always leave no evidence of an intruder:
Because tiny invisible personnel can secretly enter a target's home/office,
vehicle, etc. through electric system and leave no evidence of an intruder.
(b). Invisible personnel's murders always leave no external signs of injury
on victim's body: Because the Psy (e.g. radio-frequency weapon, infrasound)
weapons can be used to kill a target and leave no external signs of injury
on victim's body (c). Invisible personnel's murders always leave no evidence
of a struggle: Since unknowing target will not know his pain is caused by
invisible personnel's attack, he will not resist and leave no evidence of a
struggle.
Based on above three reasons, a coroner unaware of these technologies
would only conclude that the victim died of natural causes, even though
the cause of death is obvious inconsistent with the victim's overall health.
By using invisibility technology, illness/death inducing techniques, combined
with materialism & atheism, Chiang Ching-Kuo established the unlawful life control
system in Taiwan. He could achieve it because he controlled all intelligence &
surveillance system and was a communist (when he lived in
the Soviet Union).
To cause Chiang Ching-Kuo obtaining more power from his father earlier,
Taiwan's invisible personnel had used illness inducing techniques (with
acupuncture medical knowledge) to injure former President Chiang Kai-Shek's
knee to become weakness in 1960s.
After Taiwan President Chiang Kai-Shek's knee had been injured and became
weakness. Consequently, he spent most of his times in the Presidential
Mansion/Office and delegated many of his duties to his son, Chiang Ching-Kuo. On
surface, this is very similar as current King Fahd of Saudi Arabia who also
has bad knee condition and transfer more power to Crown Prince Abdullah bin Abdul
Aziz. (However, I didn't claim that King Fahd's bad knee must have been secretly
injured by Saudi Arabia's invisible personnel to force him transferring
his power. Because I have no information on Saudi Arabia. Also, Crown
Prince Abdullah bin Abdul Aziz is not the head of invisible personnel in his
country because he didn't charge intelligence agency).
Also, when seeking a special interests, they even eliminate a loyal deputy to
achieve it. For example, Taiwan invisible personnel induced cerebral hemorrhage
on Premier Yun-Chuan Sun (who was a Mainlander and President Chiang
Ching-Kuo's loyal deputy) in 1984. Why? Because Chiang Ching-Kuo's vice
President Shie (a Taiwanese politician) was injured and need to retire. Chiang
Ching-Kuo wanted to promote another Taiwanese person (whose rank is much
lower than Premier Sun) to become his next vice President. To avoid public's
question on such unusual promotion, Premier Sun was eliminated by Taiwan
invisible personnel with cerebral hemorrhage inducing technique (see details on
Part II-F2 of my website). Chiang Ching-Kuo also kept the invisibility technology
and unlawful life control a top secret without his brother's (Chiang Wei-kuo)
knowledge. Thus, Chiang Wei-Kuo ultimately became a victim of invisible
personnel. In early 1990s, Taiwan invisible personnel used chronal gun to
induce Chiang Wei-Kuo to have bad knee as his father and induced his heart's
capillaries to burst in 1996 (see details on Part II-A of my website). After
Taiwan government allowed Taiwan's citizens to visit their relatives in Mainland,
Taiwan's invisible personnel also have been arranged to enter Mainland to secretly
cooperate with China's invisible personnel for unlawful life control (Vice versa).
Why can this secret cooperation on life control between China's and Taiwan's
invisible personnel be easily achieved? Because they have secretly cooperated in
US for unlawful life control over decades under US invisible personnel's
arrangement. This kind of secret cooperation with foreign invisible personnel on
unlawful life control are mostly under US local police chief's arrangement or
supervision. Because local police have used invisibility technology, mind
control device and psy (nonlethal) weapons. So, local police station is mind
control basic unit and involved police secretly use illness/death inducing
techniques to unlawfully control local Americans' lives. Under such kind of
secret cooperation, US local police station become intelligence information
exchange center of foreign invisible personnel.
The secret cooperation on life control between Taiwan & China's invisible
personnel also led Chiang Ching-Kuo's illegitimate son Dr. Winston (Xiao-Ci) Zhang
to be murdered with cerebral hemorrhage inducing technique by Taiwan's invisible
personnel in 11/14/1994 during he visited Beijing, China for academic exchange.
Why?
Winston (Xiao-Ci) Zhang and his twin brother John (Xiao-Yan) Zhang are widely
recognized as the twin sons born out of wedlock to former President Chiang
Ching-kuo. In 1993, Dr. Winston Zhang was the President of Doung-Wu
University in Taiwan. His twin brother John Zhang was the foreign Minister of
Taiwan. Their mother was Ya-Ruo Zhang who was Chiang Ching-Kuo's personal
secretary and girl friend from late 1930s-1941 in mainland. After she had twin
sons with Chiang Ching-Kuo, she was murdered and buried in Gre-Lin, Guang-Xi
Province. To prevent these twins brothers' identities from leaking, their names
have been secretly changed. Thus, in official records, the parents of John Zhang
and his twin brother, Winston Zhang, are their mother's brother and sister-in
-law.
In 1949, Chiang Ching-Kuo's illegitimate twin sons and their maternal grandmother
were sent to Taiwan to live.
In November/1993, one of Chiang Ching-Kuo's illegitimate twin sons, Dr. Winston
(Xiao-Ci) Zhang visited his mother's tomb in Gre-Lin after he was invited to China
for academic exchange. He was told about his mother's murder then vowed to
expose the truth. However, at that time, Chiang Ching-Kuo's third son
Xiao-Yung Chiang, was a local head of Taiwan invisible personnel in US. He
knew and disliked Winston Zhang's intention then wanted to stop him. Thus,
Taiwan's invisible personnel suddenly induced Winston Zhang to have cerebral
hemorrhage on 11/14/1994 during he was invited to Beijing University for
academic exchange. Dr. Winston (Xiao-Ci) Zhang appears to be a thin person.
Such kind of person should have no serious problem on blood vessel and has
remote chance to get a stroke. Also, he didn't have warning signs of stroke and
was only 53 years old when he died of cerebral hemorrhage. It proves that his
cerebral hemorrhage must have been induced by Taiwan's invisible personnel (see
details on Part II-C3 or Part V-B2 of my website) with chronal gun (or acoustic
bullets).
The above facts prove that unlawful life control surveillance system is mainly
used to seek unlawful interests and power for invisible personnel and their head
(who has experience of using invisibility technology) of surveillance
station/system
but not for the nation's interests. These invisible personnel have no ethics,
moral
and can induce illness/death on his blood relatives. Since they even can betray
their parents, blood relatives and family, they can also easily betray their own
country to pursue their unlawful interests. Taiwan's examples prove that Taiwan
invisible personnel's not only secretly cooperate with US invisible personnel for
unlawful life control, but they also secret cooperate with China's invisible
personnel for unlawful life control. It proves unlawful life control is an
international conspiracy between every country's invisible personnel. These
invisible personnel will secretly cooperate in US, Taiwan, China, UK and any
country - no matter their own country is Capitalism, or Communism. Also, their
secret cooperation on unlawful life control will disregard that their country's
relationship is an enemy or ally. As same as Taiwan's invisible personnel, US
invisible personnel also secretly cooperate with most foreign countries' invisible
personnel for unlawful life control (e.g. Taiwan, China, Soviet Unions, UK,
France, Israel, Korea, etc.). That's why there is no national border
between invisible personnel of every country (see details on Part III-A1 of my
website). It means that any country's involved agents and police of surveillance
station/system could also use invisibility technology and illness/death inducing
techniques to secretly eliminate anyone (even betray their own country's
interests) to seek unlawful interests and power (see reported cases on Part
III-A1 of my website).
The following message of Col. Alexander proves two important things: (a). The
so-called nonlethal (psy) weapons is lethal, soft killing weapons because they can
be silently induced illness/death with no apparent reason- murder with
premeditation. (b). These so-called nonlethal (psy) weapon users (involved
agents, police & recruited civilian operatives) also use invisibility technology.
So, they can secretly deliver "microwave voice" and use microwave (or Radio
wave) weapon on American people without being seen by victims.
How can we know the so-called nonlethal (psy) weapon is lethal?
Col. John Alexander is an US scientist who has learned death science.
Col. Alexander has directed to develop the mind control technology, psychotronic
weapons (so-called Nonlethal weapons) for involved law enforcement (federal
agents, State & local police) of surveillance station/system. That's because he
know the LETHAL nature of the so-called "non-lethal (psy)" weapons. These
facts can be learned from his 1980's article in MILITARY REVIEW.
"In a notorious 1980 article, 'The New Mental Battlefield' in Military Review (an
US Army journal), when discussing Soviet research on psychotronic weapon,
John Alexander stated that "The ability to ... CAUSE DEATH can be transmitted
over distances, thus inducing illness or death for no apparent reason. When
discussing American research, Col. Alexander stated that "The use of psychotronic
weapons ...would be able to induce illness or death at little or no risk to the
operator. Range may be a present problem, but this will probably be overcome if it
has not been already. Inventor Robert Pavlita claims that no special psychic
ability
is necessary to charge the generator. The psychotronic weapon would be silent,
difficult to detect and would require only a human operator as a power source."
(see details on MILITARY REVIEW ENGLISH EDITION- DECEMBER 1980 - THE NEW MENTAL
BATTLEFIELD).
How can we know that nonlethal (psy) weapon users (involved agents & police)
also use invisibility technology?
The above messages prove that when using these weapons, the human operators
must need in scene to power the weapon as power source. Thus, when the
victims heard "microwave voices", or are attacked by so-called nonlethal weapons
(e.g. microwave weapon, infrasound weapon, radio-frequency weapon), there
must be some human operators ("at crime scene") around the victims to power
their microwave voice device and weapons. However, according to victims'
reports (see details on following source), all victims who complained of being
"zapped by radio waves" or heard "voices" never saw anybody use microwave
voice device, or weapons against them where they were victimized.

=====
When elderly parents and young children in the family become targets for
apparent purposes of intimidation. This situation has been reported in eight of
our cases, to date.
Another individual, during a telephone conversation, was told by an employee of
a local power company that, if she valued the lives of her children, she would
drop her public opposition to the company's installation of high power lines.
Since receiving that threat, the individual's 11-year-old daughter has been
reduced to extremes of pain, resulting in her recurrent hospitalization for
treatment of illnesses which cannot be diagnosed. It is also apparent to this
individual that her three-year-old son is on the receiving end of
externally-induced
auditory ("hearing" microwave voices - Alan Yu note) input.
FBI spokesmen do acknowledge that they have received a large number of
requests for assistance from "mentally disturbed persons" who believe that they
are being "zapped by radio waves" and/or "are hearing voices..."
Refusal and/or inability of local police to intervene. The tendency of local
police
is to dismiss an individual's complaints of government harassment as the
ravings of a "fruitcake." In one case, discussed above, it is apparent that one
police officer is actively cooperating in the harassment."
=====
Why the above victims didn't see any human operator who used microwave (or
radio-frequency) weapon to zap them, or used microwave voice device to deliver
voice to them (then cause them hearing voices)?
Because these human operators and weapons have used invisibility technology to
become invisible and tiny. Thus, although many victims had been attacked by
these weapons, they could not see these invisible personnel and their weapons.
Thus, combined with John Alexander's messages and these victims' experiences,
it does proves that invisibility technology has been used by local law enforcement
officers (involved FBI & police of local surveillance station/system) and their
recruited operatives to make them and their weapons become invisible. Thus,
those personnel can use their weapons (or microwave voice device) on their
targets without being seen by these targets. The above facts prove that
invisibility
technology has been used in US surveillance station/system and used by involved
local law enforcement officers. However, to prevent the invisibility technology
from leaking to society, these victims had been falsely accused as "mentally
disturbed" (see details on above source).
The following information confirm that John Alexander developed technologies
(including mind reading technology and weapons) for invisible personnel/invisible
warriors (the reality of nonlethal weapons - please see details on Part IV-A3 of
my
website).
(Source) "Some Aspects of Anti-Personnel Electromagnetic Weapons" by
David G. Guyatt on 3/8/96 prepare for Red Cross
==========
Alexander wrote a book an article (and later co-authored a book entitled The
Warrior's Edge) published in Military Review in which he outlined a number of
hitherto "fringe" subjects --including telepathy - - that should be brought in to
the
battery of future weapons. Alexander is dedicated to the development of a
super-human soldier with enhanced abilities leading to an "invisible warrior."
==========
The above information further support that the inside information from Taiwan
(about invisible personnel who induce illness/death on citizens) is completely
true.
Also, the above information also proves that US invisible personnel/invisible
warriors have used advanced technology (e.g. mind machine and new weapons
so-called nonlethal weapon ) in surveillance system to mind control or unlawfully
induce illness/death on their targets (evidences of using invisibility technology
in
US- please see details on Part II-A1 of my website).
Thus, US invisible personnel secretly spy on all important persons (from the
President, Secretaries, Congressmen, Governor, to civilians, etc.) who can
affect their interests to protect their unlawful interests.
The following two facts prove the above conclusion is true.
According to Congressional Record on 4/22/1971, House Majority Leader Boggs
said:"Today, as we in the Congress undertake to recover and restore the
people's liberty, we find that it is ourselves who are called to account,
ourselves who are under surveillance, ourselves who are prisoners of the power
which our
silence permitted to come into being. Mr. Speaker, 1984 is closer than
we think" (see details on Congress Record on 4/22/1971
Furthermore, only the invisible personnel of surveillance station/system could
secretly enter anyone's home/office to monitor every important person's activities
and private secret. Therefore, former FBI Director Hoover could embarrass an
opponent by exposing the opponent's most personal secret at a critical time.
However, the involved agents, police & operatives of surveillance station/system
will never admit it in order to keep the invisibility technology a top secret.
Thus,
invisible personnel can continuously enter American people's' homes/offices,
vehicles, to secretly spy on important persons and unlawfully control their lives
forever.
Also, in a interview, the former Russian President tells Giles Whittell (The
times' reporter on Oct. 2000) that "he knew the truth about the Monica
Lewinsky affair in 1996 long before the world did. It proves that invisible
personnel secretly spy on US President in White House (see details on Part
II-A6 of my website).
Therefore, no one can simply deny my reports without counter evidences.
Those persons who deny my reports without counter evidences or who falsely
accuse me as insane must be involved LEO & operatives of surveillance
station/system (or their collaborators).
>unprovable nonsense
Please see following report on my website:
Part II-A1: Nineteen evidences prove that inside information about US
invisibility technology from former Taiwan President Chiang Kai-Shek is
completely true.
==-=
Alan Yu
Why would I make these reports?
Because the first civil right people should have is the right to stay alive.
With God as my witness, I am positive that invisible personnel's size in
electromagnetic field are tiny as small ants (or small mosquito). They use
the tiny size with illness/death inducing techniques to easily commit
crimes because most people do not believe that the tiny invisible
personnel are existence (So far, even they cannot explain that why human
can become tiny in the invisible electromagnetic field). Anyone who does
not believe this fact can be easily murdered by the tiny invisible personnel
with non-lethal weapons & illness/death inducing techniques. My words will
be proven to be true in the future by facts that will eventually emerge.
If any citizen does not believe the invisibility technology existence, he
can write to US Congressmen of his State to question the Director of CIA, or
FBI. Also, he can write to State, County/city representatives to ask it
to police chief. However, they would only admit it in closed hearing.
Now, I would use some victims' reports to further prove that after using
invisibility technology, the personnel, equipment and their weapons will
become invisible and tiny.
Based on victims' reports and my personal experience, some victims (just
like me) have the experiences of losing some of their teeth due to attacks
by tiny invisible personnel with infrasound weapon. However, under normal
situation, infrasound weapon cannot be used to attack a target with extremely
narrow beam. But the facts is that when a victim's tooth is attacked, the
infrasound will not attack the victim's whole teeth, or damage another tooth
which is on the left, or right side of the targeted tooth.
How could such kind of crime be committed without most victims' knowledge
and why can infrasound waves be used so narrow beam to attack a single tooth
on surface?
The reality is that when these criminals are using invisibility technology, they
and
their weapons become as tiny as ants and invisible. And when the infrasound
weapon have become tiny, the side-to-side area of the infrasound weapon's
affected range becomes narrower (when compared with regular size weapon).
This allows the infrasound weapon to attack a narrow area and allows the invisible
personnel the precision to attack an individual tooth without affecting the
surrounding teeth. We know that the infrasound weapon attacks in a straight
line. If the invisible personnel is on a victim's right cheek and attacks a tooth
from there, the infrasound weapon will attack the targeted tooth in the right side
of the mouth (where the infrasound enters the mouth) and also attack another
tooth on the left side of the mouth (where the infrasound exits) - see other
illness/death inducing techniques in details on Part V-C of my website.
Now, I would further explain it in details.
The tiny invisible personnel (who enter people's home and keep the victim under
close surveillance & control) can loosen the victim's teeth while he is sleeping
by
gently landing on the area between the victim's upper lip and nose and attacking
his gums with infrasound weapon. The tiny invisible personnel can also land on
the area between low lip and chin to attack a target's gum to damage the tooth.
The goal is to cause the unknowing victim to lose his teeth as if the result of
natural causes. By using infrasound to attack the gums of the teeth, the
invisible
personnel can loosen the victim's teeth and cause them drop out. This kind of
tooth loss will be different from natural tooth loss.
Natural tooth loss will always have cavity on the tooth and will usually occur
individually. However, there is no cavity on the teeth loosened by invisible
personnel (with infrasound). This kind of tooth loss will also cause at least two
teeth to loosen or fall out when the attack is from the cheek. That's because the
infrasound attacks a target's teeth by entering through one side of the mouth and
exiting at the other side. Thus, it will not only damage the targeted tooth, but
it
will also damage tooth on the other side of the mouth where the infrasound exits.
Beside other victims' reports, I personally have same experiences of such kinds of
losing teeth by tiny invisible personnel with infrasound. My son also have
experiences of being attacked on his tooth. Because he feels a little tooth sore
or
ache. Since I have same experience on this technique, I know it is caused by tiny
invisible personnel's attack on his tooth with infrasound. So, I tell him to
attack
the tiny invisible personnel who must be on his lip or cheek to attack his tooth.
Thus, he can finally avoid losing his tooth.
It is their tactic to damage one's health and make a target's life more
difficult. Also, to stop me exposing their murders and crimes on internet,
sometime, the tiny invisible personnel would secretly land on my eye-lash and
attack my eyes with microwave weapon in order to blind me.
The above facts prove that after using invisibility technology, the personnel ,
equipment and their weapons will become invisible and tiny (as the size of small
ant). Also, the above facts prove that the invisible personnel
can use invisibility technology to steal other's document, cash, or bio-weapon
etc.
and even abduct a person. Because they can easily take the targeted objects
or abduct a person away, after using invisibility technology on a targeted person
,
or on a target's document, money, and bio-weapon, etc. to make them becoming
invisible and tiny.

When you say scaling factor, I'm not sure what you're referring to in
this paper. The authors mention that their estimate of temperature
change from doubled CO2 is less than a third of Manabe and
Wetherald's. Is that difference in the results of their computations
what you're refering to as scaling factor?

I don't disagree with a word you say. Nor do I think it tends to
support the previous poster's notion that it was the ability to
measure atmospheric CO2 concentrations that caused the shift in the
literature cited by Chambers and Brain, which is where this flurry
began.

I thought I was being helpful. And I had no idea that there was some
reason to limit my comments to the topic you now suggest. And BTW,
your description of Gast's criticism seems to avoid mentioning the
really stanky cause of the overestimation. I'd say it is you who is
closer to dissembling than me in thi example.

I see that you included this in the paragraph that started off with

There's lots of things not considered in those published pieces, and
you have indeed noted one. And I'm heartened to see you make a correct
statement about indirect effects, after the awful time you had last

I thought all the US SOx emission standards are human health-based.
But yes indeed, we have sure tightened down on powerplant SOx since
that first federal Clean Air Act of 1970.

That's very nice of you to transcribe this. I happily admit to
omitting much in my two sentences. But it's puzling that you say I
"omit the major point" when I expressly refer to what R&S describe as
"the major weakness of our model".

Because I looked at Figure 1, dummy and I looked at
Footnote 12, dummy. And Figure 1 shows that the
temperature increases logarithmically with pCO2
and Footnote 12 says multiply the y-axis on Figure
1 by 3. And, gee, even if you read the darn thing
in braille, at 10x CO2, why yeah, temperature is
still increasing, just more slowly. And wow man,
if you look at the figure caption it says:"Note that
the rate of temperature increase diminishes with
increasing CO2 in the atmosphere". Maybe that's why?

Yeah, gee, it's not hard now is it? If temperature goes as
ln pCO2 then the excess temperature rise between 2x and 10x
CO2 will be only a couple of degrees assuming no indirect
effects. Any dummy with EXCEL could figure that out.

Gracious has nothing to do with it and if I was gracious
I apologize. When you made it your mission to diss
Schneider you assumed a set of risks. You tried
to manipulate his record, excised Rasool from the
discussion and conveniently forgot about the footnote
referring to Mananabe and Co.s calcuation in order
to give a false impression and more. For purveyors
of agitprop such as yourself, it is most often true
that no one will go and look up the facts and that
even if they do your twisted facts will be what is
seen and not the corrections. For discussions of
complex material the latter is especially true, because
the truth is more complicated than the lie, and many
people's eyes glaze over the corrections.

Ah yes, the dog ate your homework, accounting rules are
not black and white, you can't prove it and more. But
I can prove that you knew about this at one time (I forgot,
I forgot, who remembers?)

If you HAD read the paper, and papers that were referenced you
would have realized that CO2 sensitivity WAS an issue at the
time. You would also have realized that there was already
a big time Study of Man's Impact on Climater: Inadertant
Climate Modification (1970) from the MIT Press, AND TOO

S.F. Singer, Ed. (1970)

The flurry began in the early 50s, when people began to measure
stuff like ice cores and Keeling got money to set up the
Mauna Loa measurements. I think he was not far off. One
of the things that makes measuring CO2 simple are electronic
detectors. They were not much available before then, lots
of spectroscopy, very little spectrophotometry. I think
the original point was not so bad.
