Eastern US Cooling Despite Global Warming 20
[Tex] writes "While the rest of the world swelters, i'll be nice and cool...this article from NASA describes a general cooling trend over the Eastern US due to global warming. Warmer waters in the Pacific have created increased cloud cover on this side of the states, resulting in lower temperatures. Jeff Goldblum could probably explain this better... :)"

It is more than a little suspicious that these atmospheric modelers never come out with a prediction; it's always the case the observations just made fit the model of a global climate change (incedentally the model most likely to increase their own salaries as well).
This un-dis-provable assertion stuff belongs more in the class of religion than science. You can't disprove "God exists;" that doesn't mean that religion is somehow wrong, it just means that religion is not a scientific type of issue. A lot of these environmental types drift over into that area: any contridictory evidence just means that "the jury is still out" until they get what they want, and the faith can never be disproven.
They need to pre-publish their models and the expected measurements. Of course the expected values shouldn't be single values, but rather probability distributions. But then at least we can have the possiblity of failure, and we would make progress on the question instead of just listening every year to the same old models tweaked to predict crisis from last year's numbers to get next year's research grants.

Iqualuit, Nunavut spent some time above freezing during the last half of December; extremely wierd weather for that time of year.
Sorry, friend. Better luck next post. (Score:1)

Me neither. But I have seen the plots showing the amount of CO2 in the atmosphere over the last 10K years, and the spike starting with the Industrial Revolution is a bit hard to ignore. It cannot be doubted that we've changed our planet's atmosphere significantly.
What the result of that is, if anything, is another matter. But since current theory holds that the current surface conditions on both Mars and Venus are the results of runaway systems, I think letting ours get out of balance is probably not a very good risk for our species to take. At least until we have self-sustaining colonies on other planets.

No, not the same chart. The one I saw was flat for about 9.8 Kyear, and then shot up on what looked like an exponential curve.

Note that previous page [uga.edu] of that site mentions that weathering of silicate rocks uses carbon dioxide from the atmosphere. Also, the geological carbon cycle has 1,800 times more carbon than the atmosphere. Our climate has a lot more variation [ciesin.org] than our last thousand years. Well, maybe you'd rather just look at the last 300 years, if the Little Ice Age messes up your statistics. Or the last 30 years, as some have used, because the 1960s had an unusually cold winter and so makes "warmer" easier to show. And please do ignore that we've stopped the prairie fires that used to cover the central plains of North America.
Note that the main greenhouse gas is water vapor [clearlight.com] which is just a wee bit hard to measure and control. And we can only hope that we don't see another Iceball Earth [abc.net.au].

Wait! Hold the presses! Global warming is a theory?
</SARCASM>
It is important to remember that global warming is, in fact, a theory. When I see a report saying, in essence "I know that what your seeing appears to be contrary to my theory, but here's why it is actually helping", I immediatly wonder at the motives of such a statement. This research appears to be done by people who support the global warming theory. As such, it's results are biased towards proving that theory.
I don't know enough about global warming to either agree or disagree with the theory. I do know enough about human nature to distrust this report.

The article said that there has been a trend of global temperature increases. The fact that the eastern US is cooling is merely an effect of the global climate changes.
That is, the fact that there is more cloud cover is usually an indication of higher rates of evaporation, i.e. higher temperatures.
So basically this articles doesn't really mean anything accept to confirm the global warming theory.

Actually, there's some concern that global warming may trigger another ice age.
Global warming --> Greenland ice starts melting --> cold water runs into North Atlantic --> Gulf Stream shuts down --> Europe freezes --> more sunlight reflected into space rather than absorbed --> new ice age.
Or something like that.
> Al Gore blamed increased blizzards on global warming. Now global warming is being blamed for cooler temperatures? No.
Global *, where * = climatic change of any type, will show up first as disruptions of traditional local patterns. Some places will get *++, others will get *--. Deal with it. And buy an all-weather wardrobe before the prices go up.
