The Northeast Blizzard: One More Sign of Global Warming http://apocadocs.com/s.pl?1293551441
It's become as much a winter tradition as eggnog at Christmas and champagne on New Year's Eve -- the first major snowstorm of the year bringing out the climate-change skeptics. And the bona fide blizzard that has frozen much of the Northeast just a few days after winter officially began definitely qualifies as major. But while piles of snow blocking your driveway hardly conjure images of a dangerously warming world, it doesn't mean that climate change is a myth. The World Meteorological Organization recently reported that 2010 is almost certainly going to be one of the three warmest years on record, while 2001 to 2010 is already the hottest decade in recorded history. Indeed, according to some scientists, all of these events may actually be connected... The loss of Arctic sea ice helps accelerate the warming of the atmosphere in the far north, thanks to what's known as the albedo effect. White ice reflects sunlight into space, cooling the air, but when ice melts and is replaced with dark ocean water, the effect is reversed and more of the sun's heat is absorbed. As the Arctic air warms, it raises the altitude of discrete areas of high pressure, which can then alter wind patterns. This, in turn, can weaken the jet stream, allowing more cold air to seep out of the Arctic and into Europe and the eastern U.S.

Just like snowmen, climate skeptics will melt.
