The Arctic is warming twice as fast as other parts of the planet. Nowhere is it more evident then in Alaska’s Yukon Delta, a vast treeless landscape, 350 miles south of the Arctic Circle. Scientist Max Holmes and the students from the Woods Hole Research Center travel there to study the effect of climate change on permafrost, which contains more carbon then in all the fossil fuels still in the ground. Previous estimates had permafrost beginning to melt over the next half century, now as they discover, the thaw could start as early as the next decade.
