cool (or not...)

A paper just came out in the Journal of Climate discussing the Arctic sea ice concentrations between 1979 and 2003. NASA's Goddard Space Flight Center has an article here, in part because this particular study uses satellite data rather than just ground-based measurements. There is a fascinating animation available as well of the changes in the minimum sea ice concentration during that time. Looks an awful lot like global warming to me, but I'm not a climatologist by any means. It's also neat just to see how the location of the coverage changes over the years - the ice pack sort of oscillates between Greenland and Russia in terms of on which side of the Arctic Circle it abuts the land.

It's definitely interesting to read things like:
Based on 20 years of data collected by infrared measurements, surface warming trends in The Arctic are eight times greater than trends over the past 100 years, suggesting a rapid acceleration in warming. According to this study, the sea ice melt season has increased by 10 to 17 days per decade.
