Numerous long-term measuring stations for monitoring permafrost conditions, micrometeorology, the [...] largest nature reserves. This unique region is crucial for understanding the processes that influence permafrost in the Siberian Arctic. The station, operated by the Trofimuk Institute of Oil and Gas Geology [...] Marine Research, the Arctic and Antarctic Research Institute in St. Petersburg and the Melnikov Permafrost Institute, Siberian Department, Russian Academy of Sciences in Yakutsk. The aim of the fieldwork

Rising permafrost temperatures raise emission of the climate gas methane

Press release

Retreating permafrost coasts threaten the fragile Arctic environment

Permafrost
Permafrost makes up a quarter of the landmass in the Northern Hemisphere. Climate change means that Arctic coasts are thawing and eroding at an ever greater pace, releasing additional greenhouse

According to estimates, Alaska's thawing permafrost soils cost the USA several 100 million dollars every decade – primarily because airports, roads, pipelines and settlements require relocation
