Although 2008 did not set a record for minimum sea ice it did set a record for speed melting. Arctic sea ice declined at a rate of 32,700 square miles a day in August. That's about the size of Maine. Every day. And that's compared to 24,400 square miles a day lost in August 2007—the record holder for minimum sea ice.
The 2008 results were surprising, says NASA, because last winter had near-normal ice cover. "We saw a lot of cooling in the Arctic that we believe was associated with La Niña," says Joey Comiso of NASA's Goddard Space Flight Center in Maryland. "Sea ice in Canada had recovered and even expanded in the Bering Sea and Baffin Bay. Overall, sea ice recovered to almost average levels. That was a good sign that this year might not be as bad as last year."
But alas the sprint in August—the fastest-ever melt—undid the gains of the winter. Here's what it looked like:
