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.
From May 5th, 2008:
“Taken together, an assessment of the available evidence, detailed below, points to another extreme September sea ice minimum. Could the North Pole be ice free this melt season? Given that this region is currently covered with first-year ice, that seems quite possible. “

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. Here is their top-down pole view:

Trend for 2008 now tucking in well on the graph for subsequent years so there is no story here. At least not yet.

If anyone is interested I’ve done an annual temperature comparison study of 28 matched urban and rural sites (each within a 100 km of each other) across the US for the past 111 years. It is quite enlightening as to AGW. This was for my son (he’s 11) and we posted it on YouTube (under Global Warming:Urban Heat Effect. Yes, I know that it should have been Urban Heat Island Effect.) Give it a look and leave a comment. Data from GISS. It is very interesting to look at long term rural site data over the world.
Thank you

Howdy,
New to the site. Some interesting reading here.
Perhaps you know that Breakpoint, a daily commentary done by Chuck Colson, has cross-referenced this page from http://www.breakpoint.org/listingarticle.asp?ID=11046. Quite interesting considering the full “Further Reading” list. But whatever. Thought you’d be interested.
