Carbon Release from Collapsing Coastal Permafrost in Arctic Siberia
A recent scientific study reported in the journal Nature reports that the ancient and large carbon pool, which has been contained in the permafrost ("Yedoma"), is being released at a much higher rate than previously estimated.
The journal Science Daily has written a great summary on the scientific article.
"Release to the atmosphere of carbon dioxide from thawing permafrost in the Arctic is identified as a positive feedback mechanism to climate warming. About half of the carbon pool in soils globally is held in frozen surficial permafrost in the Arctic (twice as much as in atmospheric CO2); the region is experiencing twice the global average of climate warming."
