Melting Permafrost: Scientists Warn of Dangers of Trapped Carbon

Research published Thursday in the journal Science says that even slightly warmer temperatures could start melting permafrost, which in turn threatens to trigger the release of huge amounts of greenhouse gases trapped in ice. The frosty dungeon hides a dark secret. At least a quarter of the Northern Hemisphere's landmass is frozen and, like a vault, it holds 1,700 gigatonnes of carbon.
