Grad student finds adding fresh carbon to permafrost triggers carbon loss
Permafrost underlies nearly 85 percent of Alaska and nearly a quarter of the landmass in the northern hemisphere. This perennially frozen soil contains twice as much carbon as is found in the Earth's atmosphere. Since the Arctic is warming twice as fast as the rest of the planet, understanding c ...
