Permafrost
How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop [...] an AWI group led by Moritz Langer has now created an interactive map of the past and future of permafrost. Both publications arrive at the same conclusion: to put a stop to the dangerous trends in these

Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal

In order to collect reliable, up-to-date information on permafrost thawing, the joint project UndercoverEisAgenten was launched today.
