Arctic sea ice now 28.7% higher than this date last year – still rallying

Posted by iusbvision on January 10, 2009

WUWT has a great post on the latest arctic sea ice data:

10/14/2008 7,064,219 square kilometers

10/14/2007 5,487,656 square kilometers

A difference of: 1,576,563 square kilometers, now in fairness, 2008 was a leap year, so to avoid that criticism, the value of 6,857,188 square kilometers can be used which is the 10/13/08 value, for a difference of 1,369,532 sq km. Still not too shabby at 24.9 %. The one day gain between 10/13/08 and 10/14/08 of 3.8% is also quite impressive.

You can download the source data in an Excel file at the IARC-JAXA website, which plots satellite derived sea-ice extent:

Watch the red line as it progresses. So far we are back to above 2005 levels, and 28.7% (or 24.9% depending on how you want to look at it) ahead of last year at this time. That’s quite a jump, basically a 3x gain, since the minimum of 9% over 2007 set on September 16th. Read about that here.

Go nature!

There is no mention of this on the National Snow and Ice Data Center sea ice news webpage, which has been trumpeting every loss and low for the past two years…not a peep. You’d think this would be big news. Perhaps the embarrassment of not having an ice free north pole in 2008, which was sparked by press comments made by Dr. Mark Serreze there and speculation on their own website, has made them unresponsive in this case.

What I like about the IARC-JAXA website is that they simply report the data, they don’t try to interpret it, editorialize it, or make press releases on it. They just present the data.
