I think it's a little odd that this graph of arctic sea ice extent suddenly stopped being updated after Nov 8, 2007. Note that for other years on the graph, we received updates after November 8.
Coincidentally, that looks to be about the date where the 2007 numbers seemed to catch up to the 2006 numbers, after trailing 2006 (to great media fanfare) by maybe 1.5 million square kilometers earlier in the fall.
On the bottom of a graph on another site, the November 2007 sea ice extent is listed as 10.1 million square kilometers. Does that indicate that as of November, the 2007 arctic sea ice extent exceeded the number from 2006?
That sea ice extent number seemed to be very important during the summer melt season, and the number was provided frequently here up to October 17.
I've spent some time looking, and I can't find an updated number for December anywhere. I wonder why that is.

Thanks, but rather than a map, I'm looking for a number (in millions of square kilometers).
