In Alaska verschwindet binnen Stunden ein See. Der Grund: tauender Permafrost. Forscher wollen nun wissen, wann das System kippen könnte und ganze Landschaften verändern.

In the Cryosphere Research Group at DTU Space, we monitor the recent and ongoing changes of the ice-covered regions of the Earth, including ice sheets and sea ice, using observations from satellites, aircraft and ground. During the past decades, satellites have observed a decline in sea ice and an increased mass loss of the Greenland ice sheet. Our research leads to an increasingly accurate understanding of these rapid changes, thus enabling society to mitigate climate change.
