Permafrost serves as an enormous carbon reservoir, containing about 1,500 billion tons of organic carbon. To put this into perspective, it holds nearly twice the carbon currently present in the ...

Beneath the frozen skin of the Earth, a silent awakening is underway. As Arctic and sub-Arctic permafrost thaws, ancient ...

Arctic permafrost contains twice as much carbon as the atmosphere. But the researchers found that the thawings—which expel stores of carbon dioxide sequestered deep in frozen vegetation—were not ...

The elder Zimov first figured out that permafrost stores far more carbon than scientists once thought. Some of it is now escaping as temperatures rise. Sergey Zimov, an ecologist by training ...

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 ...

Photosynthesising microbes in soil may increase their activity as temperatures rise, offsetting some of the carbon emissions ...

If warming continues, how will melting permafrost transform landscapes? Will forest grow in place of tundra? Will wetlands rise where forests once grew? And will these changes affect the carbon ...

This indicates that carbon input and enzyme characteristics ... the accuracy of model predictions for soil carbon dynamics in permafrost regions.
