Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns

Researchers have assessed abrupt thaw studies across the permafrost zone to estimate the overall effect. They found carbon emissions have the potential to double the climate feedback associated with permafrost thawing because abrupt thaw releases more methane. It will also have drastic effects on landscape, from altering traditional travel and hunting patterns in the North, to causing costly infrastructure damage to roads and rail lines.
