On the other hand, Arctic sea ice melting…

… faster than expected.

Arctic Ocean sea ice – one of the most visible indicators for global warming – may be headed for another record-breaking summer decline.

If the pattern continues, new research suggests, its warming effect could reach up to 900 miles inland, melting permafrost and potentially altering weather patterns at lower latitudes.
As of June 7, preliminary data show that the vast expanse of ice at the top of the world is some 55,800 square miles smaller than it was on the same date last year, according to University of Colorado researcher Sheldon Drobot. In May, sea-ice extent was slightly large than in May 2007. But the melt rate during the month – some 3,000 square miles a day – was faster, according to the National Snow and Ice Data Center in Boulder, Colo.
