I'd respect those pushers of AGW (Anthropogenic Global Warming) more is they were a little less certain, a little less in love with computer modeling, and had a little bit more humility. There is an awful lot we just don't know:
As a political joke, the idea of global warming scientists out to prove the shrinking Antarctic ice sheet becoming trapped is mildly amusing. But as a matter of science, looking at an infinitesimally small part of the ice sheet and basing any conclusions on how thick the ice is at that small section at a given point during a given time of the year is silly. The Antarctic ice sheet covers 4.5 million square miles and the local concentration of ice that covers a few dozen or even hundreds of miles is certainly not indicative of whether the entire ice sheet is growing, shrinking, or remaining constant.
That said, there doesn’t seem to be a good explanation for why part of the Antarctic ice sheet is shrinking and other parts are growing. The explanation for both cannot be global warming so there is obviously some dynamic about ice masses at work of which we are still in dark.
