Siberian Cave Climate Records Indicate Permafrost Melt
Climate records from Siberian caves suggest an impending permafrost thaw and a resulting global warming acceleration. Permafrost regions cover 24% of the northern hemisphere land surface, and hold an estimated 17,000 Gt of organic carbon. Thawing releases CO2 and CH4, creating positive feedback during greenhouse warming. The researchers, led by Gideon Henderson at the University of…
