The National Snow and Ice Data Center report of December 3, 2008:

Ice growth slows; Arctic still warmer than usual The period of very rapid ice growth that characterized October and early November has ended. The rise in ice extent over the past three weeks has been much slower, and should continue to slow until the expected seasonal ice extent maximum is reached sometime in March. Air temperatures over the Arctic Ocean stayed well above average during November, partly because of continued heat release from the ocean to the atmosphere and partly because of a pattern of atmospheric circulation transporting warm air into the region.
