Temperatures have risen twice as fast in permafrost regions relative to the rest of the globe, and many fear that as permafrost thaws large amounts of greenhouse gases will be rapidly released into the atmosphere, potentially accelerating climate change. Predicting the climate change effects of thawing permafrost, however, depends on understanding how quickly greenhouse…
