Could thawing permafrost accelerate global warming?
... Permafrost is soil that has been frozen for at least two consecutive years. It is found in large parts of the Arctic & in the Himalayas – encompassing about 25% of the northern hemisphere land area. There’s more than twice as much carbon stored in permafrost as there is in the whole atmosphere. Did ...
