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

ILLUQ Permafrost underlies 22% of the Northern Hemisphere's exposed land surface and is thawing at an alarming rate as a direct consequence of climate change. When thawing, permafrost releases large quantities [...] quantities of organic matter and contaminants into the environment. In addition, permafrost thaw dramatically impacts infrastructure in local communities with wide-ranging consequences for health, economy [...] participatory research with local stake- and rightsholders, it will provide the first holistic look at permafrost thaw, pollution and human and environmental well-being in the Arctic and deliver information on

In the future, his findings could help provide a more realistic picture of permafrost thawing.

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

Beavers are highly effective ecosystem engineers: if a given landscape isn’t quite to their liking, they simply rearrange the terrain. And that’s what they’ve been doing for millennia in [...] to their findings, the animals could change entire ecosystems and contribute to the thawing of permafrost soils, as they report in the journal Global Change Biology.

Coastal permafrost erosion, organic carbon and nutrient release to the arctic nearshore zone (COPER) Permafrost Erosion Arctic permafrost coasts account for 34% of the coasts of the Earth and are extremely [...] extremely vulnerable to climate change, because the frozen bluffs lose the cohesion provided by the permafrost matrix upon contact with seawater and are instantly washed away by incoming waves. With warming [...] e the spatial variability of particulate and dissolved organic carbon and nutrient contents in permafrost sediments and ground ice as well their sediment characteristics through cross-shore sampling transects
