Read this part of a great article from freepublic.com
Core measurements and satellite data show that the polar ice caps (arctic and antarctic) are expanding, not shrinking. The Australian recently published an article on the fact that the antarctic ice cap is growing:
ICE is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap. . . .
Ice core drilling in the fast ice off Australia’s Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Centre shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years. The average thickness of the ice at Davis since the 1950s is 1.67m.
A paper to be published soon by the British Antarctic Survey in the journal Geophysical Research Letters is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded.

Dr. Ian Allison of the Australian Antarctic Division Glaciology Program rejects alarmist claims about ice-cap melting::
Dr Allison said there was not any evidence of significant change in the mass of ice shelves in east Antarctica nor any indication that its ice cap was melting. "The only significant calvings in Antarctica have been in the west," he said. And he cautioned that calvings of the magnitude seen recently in west Antarctica might not be unusual.
"Ice shelves in general have episodic carvings and there can be large icebergs breaking off - I'm talking 100km or 200km long - every 10 or 20 or 50 years." . ("Antarctic Ice is Growing, Not Melting Away," http://www.news.com.au/story/0,27574...57-401,00.html)
The North Pole ice cap (arctic) is not melting away either. In fact, the arctic ice cap grew by 9% from 2007 to 2008:
"We have news from the National Snow and Ice Data Center (NSIDC). They say: The melt is over. And we’ve added 9.4% ice coverage from this time last year. Though it appears NSIDC is attempting to downplay this in their web page announcement today, one can safely say that despite irrational predictions seen earlier this year, we didn’t reach an “ice free north pole” nor a new record low for sea ice extent."
