For centuries, a massive store of carbon has been locked underground in the Arctic's permanently frozen soil known as permafrost. As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the result of microbes waking up and digesting once-frozen organic materials.
A new NASA-funded study focuses on a mechanism that could accelerate the release of this atmospheric carbon, the result of thermokarst lakes. These lakes form when thawing permafrost causes the ground to slump, creating a depression that collects rain and snowmelt and perpetuates a cycle of further permafrost thaw.
