Hi Rich, this is from a link from one of your previous pages ...
The past decade has been warmer than previous ones. It is the result of a
rapid increase in global temperature between 1978 and 1998. Since then
average temperatures have held at a high, though steady, level. Many
computer climate projections suggest that the global temperatures will start
to rise again in a few years. But those projections do not take into account
the change in the Sun's behaviour. The tardiness of cycle 24 indicates that
we might be entering a period of low solar activity that may counteract
man-made greenhouse temperature increases. Some members of the Russian
Academy of Sciences say we may be at the start of a period like that seen
between 1790 and 1820, a minor decline in solar activity called the Dalton
Minimum. They estimate that the Sun's reduced activity may cause a global
temperature drop of 1.5C by 2020. This is larger than most sensible
predictions of man-made global warming over this period.
It's something we must take seriously because what happened in the 17th
century is bound to happen again some time. Recent work studying the periods
when our Sun loses its sunspots, along with data on other Sun-like stars
that may be behaving in the same way, suggests that our Sun may spend
between 10 and 25 per cent of the time in this state. Perhaps the lateness
of cycle 24 might even be the start of another Little Ice Age. If so, then
our Sun might come to our rescue over climate change, mitigating mankind's
influence and allowing us more time to act. It might even be the case that
the Earth's response to low solar activity will overturn many of our
assumptions about man's influence on climate change. We don't know. We must
keep watching the sun.

Biography' (John Wiley, 2004)

Yep more of the same:
computer climate *projections*; we *might* be; *Some* members say; They
*estimate*; *Perhaps*; *some time*; *suggests* that; *might* come to;
*might* even be; overturn many of our *assumptions*; and last, but most
definitive, We don't know.
I'd bet that some people might agree with his suggestion that perhaps
climate projections are assumptions. lol

Aha, you're onto the "if but maybe" defence!
Look out Hansen et al :-))
ps quick aside that came to mind while doing the above......
remember that retiring barrier reef scientist I mentioned a cpl years ago
now when on this subject with our mate Leaf .... i recall he mentioned that
work had been done on the "acidity" of the oceans here and there, and that
die off of the coral seems to be [ there's that *seems* again lol ] from an
increase in CO2 disssolved in the water.
He reckoned that the science was pretty clear about that [ and note this is
different than anything about climate temps ] and how that is was a cause of
die-off, and that data showed the % were increasing by locality, and that %
changes matahced up with the die-offs PLUS increases in sunlight affects
causing bleaching near the surface.
OK, let's assume the sunlight bleaching is related to Sun activity only ....
but what about the CO2 dissolving in the oceans that "seemed" to be tied to
increases in CO@ levels in the atmosphere???
All rhetorical mate, not expecting you to do a science investigation or
anything, but inside me something still is saying that even if the
"analysis" and dire warnings are wrong, that there is still some importance
behind this CO2 GHG emmissions and the added issue of forest clearing and
how that affects the ecosystems. Not to mention that surely it is accepted
that land clearing, defforestation now, and in the past cummulative affects
*must be* affecting climate in some way shape or form, even if not as badly
as the IPCC suggests it is?
These questions and many more I want answered ---- but all in good time.
<smile>
Let me know when the time comes. ;-)
Actually the loss of reef really concerns me as does defforestation of the
Amazon Basin.
Saw a Cousteaus special recently and I was happy to see good changes are
happening in the Amazon.

April 13th, 2008:
"Solar Cycle 24 began on Jan. 4th with the appear-
ance of a magnetically-reversed, high-latitude sunspot.
After that, more than three months passed without
another new-cycle spot - until this weekend. The
second sunspot [990?] of Solar Cycle 24 has finally
materialized: [....] This is not a large or impressive
sunspot, but it does confirm that Solar Cycle 24 has
truly begun. In the months ahead, we can expect more
new cycle spots as solar activity emerges from its
current low ebb and surges toward the next Solar
Maximum expected in 2011-12. Stay tuned!"

2012 - Solar Max Period - September-October? 2012:
"Have we really seen the outermost limits of what the
sun can do? We can't be sure. But by the time the
next solar max rolls around [the most recent solar
max ended in 2001] - seven or so years from now
['now' is 2004. Add 'about' seven years to that, and
you get ... 2012?] - a new generation of solar obser-
vatories will be watching our stormy star, building on
an era that for solar physicists has amounted to 20
years of good seeing."
[National Geographic Magazine, July 2004, p. 33]

I don't have the article at this moment, however,
I remember reading that this solar cycle could
amount to the most devestating one in recorded
history. The reason has to do with the amount of
vulnerable technologies now on the planet. Energy
from the Sun could effectively knock out satellite
communications, the Internet, cell phones, power
grids and even electronic bank transactions. Our
technology-dependent society could suffer more
today than at any other time.

Not sure if this was the article, however, it is on topic.
"[....] Many forecasters believe Solar Cycle 24 will be big
and intense. Peaking in 2011 or 2012, the cycle to come
could have significant impacts on telecommunications, air
traffic, power grids and GPS systems. (And don't forget the
Northern Lights!) In this age of satellites and cell phones,
the next solar cycle could make itself felt as never before.

That was a test to determine where the line break
was, since a couple posts I sent came with broken
lines initially (so I deleted and reconfigured the text).
Weird that numbers will go all the way across the
page, whereas text will go only so far before it starts
breaking up.
OK, so here's a test using text (instead of numbers).
Let's see what happens.

I'd thought about this genius idea the other day about taping
a piece of string to the top of my computer monitor, and then
running it down the screen whenever I type a message to the
newsgroup.
When not in use the string could be flipped over to the other
side behind the monitor.
At any rate, I thought this was pretty creative. It makes for
a good artificial margin to show where the line breaks are.
Don't know if the rich text editor has the same line length,
but I'm about to find out.

Not everyone uses Google to read newsgroups. Each newsreader
program has it's own way of displaying and wrapping lines. So
it will appear differently on my computer and differently to
anyone else who uses a different program to look at Usenet
posts.
Hey, there may be a spiritual message here.

You mean to say that when people sign onto the Internet, and
then go to a Google Group page, that not all will be on the same
page?
Etznab
I mean to say that not everyone who reads alt.religion.eckankar
reads it through Google Groups on the internet.
This newsgroup is a part of Usenet, which is much older than
Google. It's actually older than the web.
http://en.wikipedia.org/wiki/Usenet
I read a.r.e. using Outlook Express. My ISP used to carry
a.r.e. but recently stopped carrying all of the "alt"
newsgroups, so I switched over to Supernews.
