Wieslaw Maslowski's Arctic sea ice volume decline graph from the 2010 State of the Arctic Conference: At the Forefront of Global Change, 16–19 March 2010, Miami, FL

Wieslaw Maslowski's Arctic sea ice volume decline graph from the 2010 State of the Arctic Conference: At The Forefront of Global Change, 1619 March 2010, Miami, FL

From Joseph Romm's Climate Progress:


UPDATE:  For the sake of completeness, let me end with a chart from Wieslaw Maslowski of the Naval Postgraduate School in a presentation at the March State of the Arctic Meeting (click to enlarge):

Maslowski SMALL

*This projection is based on a combined model and data trendline focusing on ice volume.

By “ice-free,” Maslowski tells me he means more than an 80% drop from the 1979-2000 summer volume baseline of ~20,000 km³.  Some sea ice above Greenland and Eastern Canada may survive into the 2020s (as the inset in his figure shows), but the Arctic as it has been for apparently a million years will be gone.
