For years now, scientists have been investigating how the gradual thawing of near-surface permafrost, which takes place in the uppermost layers of Arctic soils and in the course of decades [...] another phenomenon, which has only been sporadically investigated: the abrupt thawing of ice-rich permafrost, which can transform entire landscapes in only months of years through subsidence, the formation

The study [...] Permafrost soils store large quantities of organic carbon and are often portrayed as a critical tipping element in the Earth system, which, once global warming has reached a certain level, suddenly and
