The graphs you presented do seem to indicate a general rising trend in arctic temperatures over the last century (I think you guys call it a "hockey stick", right), superimposed on top of the wild normal year-to-year variation. But the absolute, cumulative value of this rise seems difficult to reconcile with the drastic meltoffs reported by satellite data, over the last few years, particularly the record years of 2005 and 2007, and certainly not the winter freeze indicated by TB's article. Using just the data presented on this thread, it is difficult to draw any conclusions. It must be remembered however, Arctic sea ice extent does peak in March.

What I would like to see is a set of satellite images of the polar regions, all taken on each year's minimum ice cover day, scaled and rectified to the same map projection. Even better would be if this imagery could be played sequentially as a movie.
