Warming Arctic permafrost releasing large amounts of potent greenhouse gas

Source: Science Daily

A recent study shows that nitrous oxide emissions from thawing Alaskan permafrost are about twelve times higher than previously assumed. About one fourth of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate. As temperatures increase, the peat releases more and more greenhouse gases. And, even though researchers are monitoring carbon dioxide and methane, no one seems to be watching the most potent greenhouse gas: nitrous oxide.
