Did I say the USN lies? I didn't mean to leave them off my list.

Arctic death spiral: Naval Postgrad School’s Maslowski “projects ice-free* fall by 2016 (+/- 3 yrs)”
But in the land of make-believe, Watts and Goddard say: "Arctic ice extent and thickness nearly identical to what it was 10 years ago."
June 6, 2010
One of the country’s leading experts on the Arctic projects it will be essentially ice-free (in the fall) decades ahead of the projections of the climate models used in the 2007 IPCC report. And that has quite dire implications and consequences for the likely future rate of climate change compared to those models.

The following chart is from Wieslaw Maslowski of the Naval Postgraduate School in a presentation at the March State of the Arctic Meeting (click to enlarge):

*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 ~200,00 km^3. 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....

lots more, with graphics
