In another thread on this NG Eric Swanson, to his credit, asked the
following questions (which I will paraphrase): 'You (Jim McGinn) have
repeatedly annoyed us with the questions about the, "level of confidence,"
that, "should," have been included with the results of the computer models.
What sort of answer do you expect from this line of inquiry? Why "should"
there be any such "level"?'
My response:
Firstly I'd like to, once again, thank Eric for asking such an intelligent
question. I'm going to do some research on the internet (using keyword
searches eg. confidence, statistics, verification of computer models etc.)
to see if I can formulate an intelligent response. In the meantime I
thought I'd open the floor to anybody else that might like to address this
important issue. Anybody?
You suddenly appeared quoting the ORGANIZED CRIME RING CATO INSTITUTE
OF FELONY FRAUDS. What is your relationship to them?
You next quoted CATO FELLOW FRED SINGER, a notorious whore and science
hoaxer who is outcast from science for life because of crimes more
shameful than the Korea Stem Cell Hoax. What is your relationship to
the Whore Fred Singer?
Following immediately, you posted a quote from the CATO Whore FRED
SINGER's website SEPPtic Tank, which for a long time shared offices
with CATO co-founder Charles G. Koch Summer Fellows Program that steers
gullible interns into spamming usenet for minimum wage.
Are you getting minimum wage for spamming usenet from a windowless
boiler room next to the trash dumpster in CATO's basement, or are you
getting less. [Hint: for a big pay increase cop some of the
confidential papers from the shredder bag and blackmail them to get out

"The climate system is too complex," Mosley-Thompson said. "Even the most
complex climate model doesn't get it right. And why is that? Because who

particular phenomenon, then how can you incorporate it into a climate
model?"
The fact that different computer models often produce different forecasts
doesn't offer much reassurance. For example, one model predicted that the
Southeastern U.S. would become more jungle-like in the next century, while
another model predicted the same region would become a dried-out savanna,
according to Dr. John Christy, a professor of atmospheric science at the
University of Alabama in Huntsville.
" . . . taking polls on the opinion of people who's income is tied to the

is often the case."
"Climate science is often reported as if a 'run' of a computer model is an

'Supporters will further say, "Many of these scientists are established,
world-renowned, tenured professors who do research in numerous areas and

trained to look at numbers trends and graphs and form conclusions about the
probability of future events. They know that seeing patterns in data can be
the playground of fools (are there any fool-proof computer programs that
accurately predict the stock market?) More importantly, a meteorologist's
experience will have taught them to be very careful about making claims
about the future with limited data. Perhaps this experience has given them a
better feel for what is knowable than the global climate researchers? The
"science of climate change" has been quite wrong before when they were
predicting a "new Ice age". Real science requires something that is beyond

The great computer models used to predict the dire consequences don't have

Water vapor tends to condense into water droplets at nucleation sites. These

and even agitation of air. Nuetrenos and cosmic rays are not constant, they
vary with solar storms and the position of solar storms on the sun. They
are also non linear. The lack of clouds in the model reduces this to a
political campaign - one I would tend to support - but not at the expense of

So many errors, so little time.
Modern meteorologists use models every day. Besides, weather is not climate.

Pure bullshit. The notion that "cosmic rays" influence cluds is an unproven
hypothesis, if that. The rest is pure crap, as the models do include clouds
and the hydrological cycle. They have also been forced with solar variability
and volcanic effects, the latter which the Soon & Baliunas graph ignores.

Yes, and they are humbled by the limitations of their model's predictive
power on a daily basis. Climatologists don't have this. The lack of
testability of their longer term models inspires arrogance.

Would you agree, however, that confidence estimates of model predictions
should be published with the results?
Jim
> Would you agree, however, that confidence estimates of model predictions
> should be published with the results?
There is indeed a lot of uncertainty in what the future will be, but this is
not all because of an imperfect understanding of how the climate works. A
large part of it is simply not knowing how the human race will react to this
danger and/or how the world economy will develope. Since these factors
control what emissions of CO2 will accumulate in the atmosphere, which in
turn influences the temperature, there is really no way for a climate model
to predict what the future will be.
What modelers can do, however, is talk about and estimate the climate's
sensitivity to CO2, usually in terms of how high the temperature will rise
given a doubling of CO2. See the Real Climate glossary entry for climate
sensitivity.
http://www.realclimate.org/index.php/archives/2004/11/climate-sensitivity/
So how much certainty is there? This varies from model to model but
typically a projection is given as a most likely temperature together with a
range that encompasses all the likely values. In the IPCC report "likely" is
defined as a 70% probability. If you want a specific number and range, you
must chose a specific scenario of emissions over time and a specific model.
The IPCC does note that:
"The globally averaged surface temperature is projected to increase by 1.4
to 5.8°C over the period 1990 to 2100. These results are for the full range
of 35 SRES scenarios, based on a number of climate models."
http://www.grida.no/climate/ipcc_tar/wg1/008.htm
But what about the certainty of this summary of model predictions? Well, a
recent paper by James Annan et al. (
http://www.jamstec.go.jp/frcgc/research/d5/jdannan/GRL_sensitivity.pdf ) has
attempted to clarify this question by statistically combining the
certainties of a wide variety of models in a variety of situations. Focusing
on climate sensitivity, they conclude that in terms of the climate's
response to a doubling of CO2, the model's say:
"The resulting distribution can be represented by (1.7,2.9,4.9) in the
format used throughout this paper. That is to say, it has a maximum
likelihood value of 2.9oC, and, using the IPCC terminology for confidence
levels, we find a likely range of 2.2-3.9oC (70% confidence) and a very
likely range of 1.7-4.9oC (95%). We can also state that climate sensitivity
is very likely to lie below 4.5oC(95%). These results represent a
substantial decrease in uncertainty over those originally presented in NAS
[1979] and in subsequent research. They also imply that the sensitivity
range of modern GCMs (2.1-4.4oC) is likely to include the correct value
(with greater than 80% confidence)"
So, most likely value is 2.9oC with a 95% probability of falling between
1.7oC and 4.9oC.
There is a summary and discussion of this paper at Real Climate.

This is the soft underbelly vulnerable to attack. Never mind the fact
that computers need not exist anywhere on the planet and there are
still six independent trails of evidence confirming without shadow of
doubt that Global Warming is Real, it is happening NOW (not in a
century from now), and it is a serious threat.
The enemies of humanity keep turning the entire Global Warming thing
into an argument over climate models on computers. By the time you ever
win that argument the rest of us will all be dead already from severe
inhospitable climate change.
Don't argue on their turf. When you know you have a troll, arguments
serve only to "create an illusion of an ongoing controversy", go to the
indisputable evidence that the trolls are not equipped to deal with.

Actually, there is a considerable truth in Inhofe's speech. That's the
problem, as the "truthiness" makes it seem his conclusions are correct.
Sure, there are some areas where the models are weak. That doesn't mean
that all model results may thus be ignored.

I agree. Or, at least, not with 100% accuracy. The question is how much
confidence should we attribute the models.

This is kind of an underhanded (intentionally deceptive) way of pretending
to claim that the confidence associated with these models is 70%. The
"likely" in the IPCC report applies to the various scenarios of consequences
*if* AGW projections are true (and even then it focusses on the most
dramatic).

You are confusing confidence with range.

This (95%) is not the confidence of the model results. This indicates ONLY
that 95% of the data points in the various runs of the model fall between
1.7-4.9oC. You could have a hundred differerent models and each of them can
produce a narrow range of data and all of them can be wrong if they all
carry the same erroneous bias in their assumptions. Keep in mind that the
assumptions that are put in one model are likely to be the same assumptions
put in another model.
I think future human behaviour is arguably the largest uncertainty in the
equation. This is why there are so many scenarios in the IPCC projections.
You can not make a climate model prediction of temperature in 2050 or 2100
without knowing how much CO2 we will continue to emit year by year. There
are also natural forcings such as volcanic action and solar variations that
alter any projection as soon as it happens.

The basic conclusion that continued emissions absent massive volcanic action
or thermo-nuclear war will result in continued warming is a virtual
certainty.

I suspect that this is the source of 95% of the hysteria regarding GW. I
suspect that Hansen is *fully* aware of this. (How could he not be, being a
NASA scientists.) The actual, statistically determinable,
accuracy/confidence of *any* climate model projected out more than even *one
year* doesn't even amount to 1%. Think about that. And this is empirically
demonstrable. Beyond dispute.
Why do you think it is that Hansen refuses to discuss this subject?

The difference between the sensitivity/range of a computer model (which is
typically determined by way of multiple runs of a computer model using
slightly different starting conditions) and the confidence/accuracy of the
end result of any particular run of the model is, to use Mark Twain's words,
like the difference between lightning and the lightning bug.

No.
Errors in climate models do not accumulate geometrically. No. In steady
state forcing a climate model produces a stable climate.
> Think about that.
I think I see what you are thinking. It is wrong.
> And this is empirically
> demonstrable. Beyond dispute.
No. You are confusing weather and climate. Climate models with steady
forcing have a steady climate. They have seasons, storms, and droughts,
but the likelihood of such events does not change from model year to
model year. Therefore, there are demonstrably cases where the error
does not accumulate.
You can't wheel out elementary arguments and expect an entire
scientific discipline to have missed the point. That's completely
silly. Stuff that can be refuted with a pocket calculator doesn't make
it into Science and Nature for twentyfive years. Sorry. There are a lot
of broken institutions in this world, but science is not that broken
yet.
> Why do you think it is that Hansen refuses to discuss this subject?
Because he is an important man and can't spend time refuting every
half-baked theory of every amateur.
mt
That's not true. All of the Atmospheric Global Climate Models used for the
kind of climate projections reported on by the IPCC take the effects of
clouds into account. You can read a discussion about cloud processes and
feedbacks in the IPCC TAR.
http://www.grida.no/climate/ipcc_tar/wg1/271.htm
It is true that clouds are one of the largest remaining uncertainties in the
GCM's. They are very complicated to model because they have both positive
feedbacks by preventing IR from escaping to space and negative feedbacks by
reflecting incoming sun light before it can even reach the surface. The
precise balance of these effects depends on the time of day, the time of the
year, the cloud's altitude, the size of water droplets and/or ice particles,
the lattitude, the air temperature and the cloud's size and shape. Different
types of clouds will also interact as they co-exist in different layers of
the atmosphere. There are also latent heat considerations as water condenses
during cloud formation and evaporates as clouds dissolve.
The ultimate contribution to global temperature trends is very uncertain,
but likely to be positive over the coming century.

he has associated himself with Killer Koch Brothers Organized Crime
operations, including Cato Institute, so strongly that GOOGLE.COM
automatically pops Jim McGinn up to the top of the list if you look up

Irrelevant. They are not "true" experiments, they are computer
models. The quality of the model depends on the quality of the data
that was used to build the model, and the knowledge and ability of the
programmer.
If the programmer makes an error, the code doesn't run correctly. If
the programmer uses the HITRAN database, and HITRAN is shown to be in
error regarding the absorption spectra of water vapor, then the model
doesn't work correctly... For example, you might discover that you
underestimated the water vapor feedback mechanism by 3-4 Watts/m^2:
http://www.cgd.ucar.edu/cms/wcollins/papers/newrad.pdf
(2005)
And where would your models be then? Are you sure that there are no
other errors in the HITRAN database?

Matching "rather well" isn't sufficient, in most cases.

Retief
> There is science there --
> something to be learned there!
Models do not verify Global Warming -- Physical Evidence does.
There is science there and CORALS NEVER LIE.
There are six main trails of conclusive evidence which make
anthropogenic (Man-Made) definate beyond any reasonable doubt.
Each one of these trails confirms all of the others.
+++ Coral Bleaching in 1998. It never was worse than that during any
time since apes stood upright. There would be massive fossil beds of
corals to testify to higher sea temperatures. The best fossils are all
within 6,000 years old and they are clear and unambiguous. There never
was a worse coral bleaching event in the last 6,000 years than 1998.
1998 came within two degrees of killing 90% of all the nurseries of the
ocean. Any event which ever killed 90% of the nurseries of the ocean
are recorded in fossil beds -- it happened five times in global
history, and the last time was 65,000,000 years ago, when the Alverez
Asteroid struck near Yucatan.
So we have established without doubt that 1998 is as hot as it can get
with higher oceanic life surviving. Fortunately for the oceans, vicious
storms have been relieving the heat content of the seas sufficiently so
that oceanic life is continuing, although 2002 was also a bad year for
coral bleaching. We have to pray for hurricanes to save us from death
of higher life in the seas.
+++ Another trail leading to the inescapable conclusion of Man-Made
global warming is the flooding rate in Bangladesh. This one is far more
complex, and has plenty of superficial confounding-appearance data.
First, there was a massive earthquake in the 1950s which changed river
course and land elevations. Second there was a political change when
"east" Pakistan became independent. Govt records are likely confused
and may still reside physically divided between countries. Third, the
generalized poverty means that good science and good archives are hard
to maintain.
Despite these illusions of confounding, the history of the area is not
a blank. It has been highly densely populated for centuries. India has
kept better records of the area. It has always had some flooding of
intermittant amounts and intervals. The poorest population gets the
floodplains because nobody else wanted them -- they adapted to short
flooding of mild levels of localized nature and could move out of the
way.
The cultures celebrate the changes of the seasons in various traditions
and festivals. The melting of the Himalaya snows is fairly predictable
and steady, just like the monsoons arrive within days of a calendar
date each year. Deforestation below the treeline does not completely
explain earlier dates of annual melting above the treeline.
Severe flooding began after 1954. It first occurred an average of ten
year intervals. In the recent time span it has progressively increased
in frequency, secondly to about every 6 years, now to every other year.
Blame Game has put the cause on upstream deforestation, but there is
earlier snowmelt each year.
That snowmelt was separated from the monsoons by time, and the two peak
water flows were separated by time. Now the snowmelt coincides by date
with the monsoons and record-breaking historically severe flooding is
the result. Nothing this severe is known for hundreds of years, and the
frequency of repetition is a physical impact requiring a physical
explanation.
The flooding is confirmed by the greenhouse gases causing Global
Warming. One must provide an alternate explanation for the trapped heat
to escape the system. Unless one can do that, the provisional
explanation, Man-Made Global Warming, stands unchallenged.
+++ Massive retreats of glaciers and icepacks. One must explain the the
sudden rate of increased meltaway. Global Warming explains this effect
without sweeping any data under the rug. Greenhouse Gases are trapping
heat in the system.
+++ Increased temperatures recorded across the globe by every measuring
means available on the planet. Records are broken with regularity. The
coral bleaching limit shows these are not representative of cyclic
heating events, but are anomalous in the geological record. Nothing
like this has happened in 65,000,000 years of fossil evidence. All the
direct and proxy temperature measures agree within acceptable errors
ranges.
+++ El Nino is a direct effect of sea surface heat accumulation. While
El Nino leaves poor records in the fossil archives, the known observed
rate was averaging 7 years between El Nino events. With greater recent
measured thermal storage in the sea surface, the El Nino events have
been forced to 2-3 year intervals. Physical events require physical
exlanations. The explanation which fits the measurements is Global
Warming from Man-Made Greenhouse Gases.
+++ Storm intensity and frequency is directly related to heat fuel
stored in the tropical oceans. Currently there is peak for all
recorded history of 25% more total hurricanes, more severe hurricanes
and closer frequency of hurricane-level storms. Add that to 500
tornadoes on land in the USA in May 2003 and you see tangible proof of
heat-engines at work disposing of surplus heat according to the best
modern physics theories.
NOBODY has a comprehensive alternate explanation which explains ALL of
this data, and any explanation which fails to explain ALL of the data
may be downrated as attempted Leprechans at work.
Besides the main trails there are many minor trails of evidence, all
confirming, none positively disconfirming the Man-Made Greenhouse Gases
Explanation.
All of the attempted counter-explanations deal with one trail at a
time, such as land-use changes and deforestation upstream from
Bangladesh. All they prove of a certainty is there are piggish humans
who care nothing about the downstream misery of those less fortunate,
thereby strengthening the case against the organized crime rings
falsifying science and committing felony frauds to piggishly injure
downstream less-fortunates. That evidence confirms criminal psychology,
but does not injure the measured recorded and reliable evidence of
increased frequency beyond the power of deforestation only to cause.
No, not unless you have a high degree of certainty about things like human
emission of CO2 for the next 100 years.
