Has it ever occurred to anyone that Greenland got its name because at one time it was, in fact "green land"? At one time in the not-too-distant past, it was lush farmland which supported the farming of livestock. Ice core samples from the southern fjords suggest that its climate was relatively mild until the beginning of the Little Ice Age in about the 14th century. The polar pack ice Kevin refers to began its southward advance around then.
There was also an item on the news several weeks ago about huge glacial ice masses breaking off the Antarctic ice cap.
There was also this item about Antarctica getting colder:
Bremerhaven, April 21, 2008. The Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record. In the coming years autonomous measuring buoys will be used to find out whether the cold Antarctic summer induces a new trend or was only a "slip". (emphasis supplied).
This just proves that the earth is getting warmer and colder all the time, just as it always has. To paraphrase Ecclesiates 1:9, "...there's nothing new under the sun." Computer models which purport to predict climate change are also notoriously inaccurate due to the fact that computers cannot accurately account for the role of water vapor and other variables. It's sort of like trying to figure out how a movie ends by watching the trailer.
