Methane (CH4) is a potent greenhouse gas that is roughly 30 times more harmful to the climate than carbon dioxide (CO2). Both gases are produced in thawing permafrost as dead animal and plant remains are decomposed. However, ...

(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, ...
The Arctic's frozen ground contains large stores of organic carbon that have been locked in the permafrost for thousands of years. As global temperatures rise, that permafrost is starting to melt, raising concerns about the ...
