apparent scars in the world’s permafrost regions. As the new global comparative study conducted by the international permafrost network GTN-P shows, in all regions with permafrost soils the temperature of the
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
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
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
Coastal erosion in the Arctic The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 meters of land per year at some
in the Arctic are no longer just the domain of scientists. The shrinking sea ice and collapsing permafrost coasts are now also becoming topics on the agenda of international politics and industry. To be
Permafrost The Arctic is warming more strongly than any other region on Earth, which leads to serious erosion of coasts where organic matter was frozen in the permafrost for thousands of years. Once
Permafrost The permafrost regions of the Arctic, often referred to as nature’s iceboxes, contain tremendous amounts of carbon, mainly in the form of animal and vegetable matter accumulated in frozen [...] considered in permafrost emission estimates so far. As they report in the journal Nature Geoscience, abrupt thaw processes, which are possible in ca. five percent of all Arctic permafrost landscapes, could
their new homes, creating a host of new water bodies. This could accelerate the thawing of the permafrost soils, and therefore intensify climate change, as an International American-German research team
Permafrost Experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), the Humboldt-Universität zu Berlin (HU) and the University of Oslo have determined that much [...] much of the permafrost that is currently still very cold might disappear by the end of the century. What’s new about their simulations: the inclusion of thermokarst processes. The outcomes of the study
