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.

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
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
