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 ...

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 ...
