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.

Permafrost
The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena [...] every year, roughly 15 metres of the riverbanks crumble away. In addition, the carbon stored in the permafrost could worsen the greenhouse effect.

Lakes in the northernmost latitudes are widely considered to be a significant source of the greenhouse gas methane. In order to improve currently available climate-change projection models

Typical for remote sensing [...] research? In our group we focus on the ice sheets of Antarctica and Greenland, on sea ice, and on permafrost regions. Typical questions are: Which sea ice types can be separated in radar images? How do polynyas [...] and deformation? Which sensor combinations are optimal for classification of land cover units in permafrost regions? How can we retrieve snow accumulation rates from satellite data? The results of our analyses

thawing in permafrost regions, e.g. in Sibiria. CH4 introduces a significant feedback mechanism to the climate change problem, as global warming leads to a poleward retreat of vast permafrost regions in
