Decadal doubling of Siberian methane emissions due to warming-induced fires and methanogenesis.

The northern permafrost region, which stores double the amount of carbon in the atmosphere, is vulnerable to accelerated warming.

The northern permafrost region, which stores double the amount of carbon in the atmosphere, is vulnerable to accelerated warming. Methane emissions from thawing permafrost may eventually result in a climate-carbon feedback. Our analysis of atmospheric methane data shows that…
