Permafrost collapse is accelerating carbon release

We estimate that abrupt permafrost thawing in lowland lakes and wetlands, together with that in upland hills, could release between 60 billion and 100 billion tonnes of carbon by 2300. Although abrupt permafrost thawing will occur in less than 20% of frozen land, it increases permafrost carbon release projections by about 50%. There should be better tracking of permafrost and carbon across the Arctic, especially in regions undergoing abrupt thawing.
