News release: “New data, released by the Catlin Arctic Survey and WWF, provides further evidence of thinning Arctic Ocean sea ice, supporting the emerging thinking that the Ocean will be largely ice-free in summer within a decade. The Catlin Arctic Survey, completed earlier this year, provides the latest ice thickness record, drawn from the only survey capturing surface measurements in the last winter and spring.

“The Catlin Arctic Survey data supports the new consensus view, based on seasonal variation of ice extent and thickness, changes in temperatures, winds and especially ice composition, that the Arctic will be ice-free in summer within about 20 years, and that much of the decrease will be happening within 10 years. That means you’ll be able to treat the Arctic as if it were essentially an open sea in the summer and have transport across the Arctic Ocean.”
