effects and causing the permafrost to thaw in step with climate change. As such, taking decisive action today is all the more important if our goal is to preserve as much permafrost as possible. 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
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
Many of the models used to make climate projections are unable to dynamically reflect permafrost. A new study involving experts from the Alfred Wegener Institute has for the first time applied an extensive [...] extensive ensemble of 17 climate models to quantify how said models portray permafrost in warm climates. Drawing on a comparison of models for a warm period during the mid-Pliocene roughly three million years [...] Proceedings of the National Academy of Sciences the researchers conclude that the near-surface permafrost extent was less than 10 percent of that seen in the preindustrial era.
quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations, published in Earth System Dynamics , show that
A previously underestimated risk lurks in the frozen soil of the Arctic. When the ground thaws and becomes unstable in response to climate change, it can lead to the collapse of industrial infrastruct
New Study As a result of global warming, permafrost regions around the world are thawing now. As they do, climate-relevant greenhouse gases containing carbon (carbon dioxide, methane) and nitrogen (nitrous [...] climate forecasts. Whereas substantial research has been conducted on the carbon reservoirs in permafrost, we still know comparatively little about nitrogen. A team of experts led by the Alfred Wegener
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
Permafrost 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
