Sea Ice 2008

November 10, 2008

Arctic sea ice declined this summer to its second smallest extent in the satellite era, suggesting that the record set in 2007 may not have been an anomaly. If recent trends in the melt rate continue, we could see a virtually ice-free Arctic each summer much sooner than previously thought.
