Arctic ice trend

leave a comment »

A couple of commenters have said that the Arctic ice cap is doing quite well. They’re wrong:

Can you see the trend?
Can you see the trend?

Graph is from this report, which notes:

Arctic sea ice extent averaged over the month of August was 6.03 million square kilometers (2.33 million square miles). This is 1.64 million square kilometers (633,000 square miles) below the 1979 to 2000 August average,

However, August 2008 was still 670,000 square kilometers (260,000 square miles) above August 2007, despite the record-breaking rate of decline over the past month. Why would this be? The best explanation for this is that this summer did not experience the “perfect storm” of atmospheric conditions seen throughout the summer of 2007.

Even though August ice extent was above that of August 2007, the downward trend for August ice loss has now gone from -8.4% per decade to -8.7% per decade.
