Permafrost Thaw

Permafrost thaw is a critical hazard for everyone on the planet. Globally, greenhouse gas emissions from permafrost thaw will accelerate warming, requiring greater reductions in human emissions to stabilize the Earth's temperature. Locally, permafrost thaw results in erosion and subsidence, threatening the homes, livelihoods, and traditional ways of life of Arctic residents. We are working with decisionmakers to integrate cutting-edge science into more robust policy and programs for mitigation, adaptation, and resilience.

Leaving Russia out of any attempt to understand what is going on across the world in permafrost leaves out a very big part of the problem.
