(Phys.org)—A small team of researchers working in Greenland has found that as microbes become active in permafrost, they produce heat, which can increase the rate of permafrost loss. In their paper published in Nature Climate ...
According to a recent study published in Nature Geoscience, scientists have found that soil carbon dioxide (CO2) emissions are more sensitive to climate warming in permafrost-collapsed areas than in non-collapsed areas.
