Earth’s permafrost is thawing almost everywhere scientists look
The study found active layer thickness increased at 55% of Arctic sites and 38% of Antarctic sites, with mountain regions changing fastest.

Permafrost in rapid decline across the globe
A new global study has revealed that permafrost is degrading across the globe at an unprecedented rate, with some mountain regions experiencing active layer thickening at more than 36cm per year. While permafrost is, by definition, a permanently frozen layer of ice, on top of this sits the active layer, which thaws and refreezes each year according to the seasons. The thickening of this layer comes at the expense of the permafrost. The research,…
A new study shows that the thawing of permafrost not only leads to the release of carbon, but can also promote its removal from the atmosphere. Under certain conditions, the removal even exceeds the emissions.
An international study conducted by researchers at George Washington University makes it clear that permafrost is melting on a large part of the planet. Building on more than two decades of field observations from 156 monitoring sites in the Arctic, Antarctica and upper Arctic regions, it is [...]
Global study indicates widespread permafrost degradation
First international global assessment of long-term active layer monitoring data at the George Washington University Department of Geography and Environment demonstrates clear global evidence that permafrost is thawing across much of the planet.
