News From the AGW Front
The Northern Ocean sea ice is about a million square kilometers below the 1979-2008 "normal" average. So it's down about the size of Egypt, but more than two standard deviations below the purported baseline. Of the 14 distinct areas in the Arctic, however, only 4 are really seriously below average--three of them front the Northern Atlantic (St. Lawrence; Newfoundland/Baffin Island; and Greenland Sea). The other is the Sea of Okhotsk, south of Kamchatka for all you Risk fans.
But as we were chided when we Deniers noted the rapid recovery in sea ice area after the 2007 big melt, area only tells part of the story, the other component is sea ice thickness. Here's a chart of the ice thickness in Feb. 2008 compared to now, Feb. 2011. As you can see, the thickness is up substantially and thus the ice volume is up as well, over 25%. So the Warmies all decry the lack of four year ice (4 meters thick) and will until 2013, when the recovery from 2007 is five years old and there is much more four year/4 meter ice.
The predictors of an ice free Summer Arctic Ocean within a few years (or decades) are looking to sound ever more foolish.
I'm going to a Warmie lecture this Thursday. I'll report back.
