Nearly half of the organic carbon stored in soil around the world is contained in Arctic permafrost, which has experienced rapid melting, and that organic material could be converted to greenhouse gases that would exacerbate ...

One of the big unknowns in predicting climate change is the billions of tons of carbon frozen in Arctic permafrost. As global warming causes soil temperatures to increase, some of this carbon will decompose and enter the ...

(Phys.org)—An international team of researchers has found that carbon uptake in the Tibetan Plateau may actually offset the carbon that is released as permafrost melts. In their paper published in the journal Nature Geoscience, ...
Permafrost soils in the Arctic are thawing. As they do, large, additional quantities of greenhouse gases could be released, accelerating climate change. In Russia, experiments are now being conducted in which herds of horses, ...
