The far north holds more than twice as much carbon as is found in the atmosphere today, so thawing permafrost could drastically affect climate. But the region's remoteness and complex terrain make ...

Both are caused by a warming global climate. But exactly how these two types of permafrost thaw affect landscapes and local communities, as well as how much additional carbon dioxide and methane they ...

The upshot is that Arctic permafrost is much richer in carbon than scientists once thought. We aren’t accounting for that. The UN’s Intergovernmental Panel on Climate Change has only recently ...

Thawing permafrost would act as a positive feedback to warming—adding to global warming via emissions of carbon dioxide—with the amount depending on how much anthropogenic forcing of climate ...

The widespread permafrost in this region, where soils currently store twice as much carbon as the atmosphere, is thawing. Scientists are using increasingly detailed climate models to investigate ...

Permafrost — the permanently frozen ground that underlies much of the Arctic land surface — is thawing in many parts of the Arctic. [1] As permafrost thaws, it releases the powerful greenhouse gas ...
