Quote:The new study finds that "Our spatial analysis of Antarctic meteorological data demonstrates a net cooling on the Antarctic continent between 1966 and 2000, particularly during summer and autumn." The McMurdo Dry Valleys, for example, have cooled about 0.7 degrees Celsius per decade during this period of time.
The authors conclude that, "Continental Antarctic cooling, especially the seasonality of cooling, poses challenges to models of climate, and ecosystem change."
Your second source is... I'm not sure what it is, a clearing house... but here are some of the sponsors of globalwarming.org:
-- Americans for Tax Reform (Grover Norquist; very little room to the right of him)
-- American Legislative Exchange Council (right wing)

Not liberals, these.
The fact that ice is melting rapidly in Antarctica is difficult to dispute.

And, as far as the Wall Street Journal, they won't buy into the idea of global warming until most of their newsroom is under water.

It's just funny how that scientist in the CNN article said that ice is on the decline "everywhere". Exaggeration and a little scare-mongering, perhaps?
As for your source: I know NASA is a credible source as well, but they do have that little ".gov" domain in their address. Doesn't mean they're lying, but it is a publicly tax-funded institution that may have an agenda just as much as any "right wing" site may have.
I think there are five camps:
1. Those who believe global warming is caused solely by man
2. Those who believe global warming is caused by solar activity
3. Those who believe global warming is a natural cycle
4. Those who believe global warming
may be happening, but unsure why, or it could be caused by a variety of reasons (including man, solar activity, natural climate cycles, etc)
5. Those who refuse to believe global warming is happening at all
I tend to side with #4 more often than not.
