Earth's permafrost likely to disappear by 2200 due to global warming: study

Earth's permafrost likely to disappear by 2200 due to global warming: study

Using Intergovernmental Panel on Climate Change scenarios and land-surface models for the study, the researchers ran multiple Arctic simulations assuming different rates of temperature increases to forecast how much carbon may be released globally from permafrost in the next two centuries.

After taking into account all of the permanently frozen ground at high latitudes around the globe, the researchers estimate a release of roughly 190 billion tons of carbon, most of it in the next 100 years
...
"The amount we expect to be released by permafrost is equivalent to half of the amount of carbon released since the dawn of the Industrial Age," said Schaefer.


Note: the IPCC was way too optimistic
