From the National Snow and Ice Data Center, the Arctic sea ice extent graph (remember, even though the curve is following the curve for 2007, the ice is probably half as thick as it was in that year):

Cassandra,
Where does the half as thick # come from? Last year the ice massset a new low, but not by a large margin. You got a link for me?
Thanks.
The comparison is to the mass of 2007, not 2008, but still very much back of the envelope.
ccpo, seems my back-of-the-envelope estimate was conservative, see here:

I will be posting the abstract of the Kwok and Zwally article when available.
