investigation into the rapidly changing permafrost regions in the northern hemisphere. The project seeks to answer pressing questions about the role of permafrost thaw in the global climate system, and [...] the people living in these regions. The culmination of this ambitious endeavour is the "Arctic Permafrost Atlas," a ground-breaking publication set to launch during the Arctic Circle Assembly on October
glaciers and sea ice, can be observed directly, most of the permafrost’s melting takes place deep below the surface. However, since the permafrost stores huge quantities of carbon, which is released in the [...] thawing will further worsen global warming. In order to collect reliable, up-to-date information on permafrost thawing, the joint project UndercoverEisAgenten was launched today.
Permafrost The fate of permafrost - soil that is frozen for 2 or more years - is of huge importance for the global climate because of the large amounts of organic carbon stored in it, which can be released
Permafrost In the future, climate change could abruptly increase the amount of methane released by lakes in the permafrost regions of the Arctic. The explanation: because of thawing permafrost, these
Scientific Publication Permafrost coasts make up about one third of the Earth’s total coastline. As a result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the [...] now shows that large amounts of carbon dioxide are potentially being produced along these eroding permafrost coastlines in the Arctic.
Permafrost 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
Nature Communications Study The loss of arctic permafrost deposits by coastal erosion could amplify climate warming via the greenhouse effect. A study using sediment samples from the Sea of Okhotsk [...] Okhotsk on the eastern coast of Russia led by AWI researchers revealed that the loss of Arctic permafrost at the end of the last glacial period led to repeated sudden increases in the carbon dioxide concentration
Permafrost Throughout the Arctic, ice wedges are thawing at a rapid pace. Changes to these structures, which are very common in permafrost landscapes, have a massive impact on the hydrology of the tundra
for his doctoral thesis, which represents a valuable contribution toward refining simulations of permafrost development: in it, he demonstrates the importance of small-scale landscape characteristics, since [...] a result of thawing. In the future, his findings could help provide a more realistic picture of permafrost thawing.
Permafrost The frozen permafrost in the Arctic is thawing on an alarming scale. By analysing an annual record of satellite images, researchers at the Alfred Wegener Institute have now confirmed these
