emissions of the greenhouse gases methane and nitrogen so high outside the vegetation periods in permafrost regions? How do the carbon and nitrogen cycles and the resulting greenhouse gas emissions differ
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.
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.
Permafrost 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
Permafrost 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
Palaeoclimate While determining the age of a permafrost layer in Siberia, an international team of experts set a new record: at its deepest point, the soil is at least 650,000 years old. Yet the team’s
glaciers and sea ice, can be observed directly, most of the permafrost’s melting takes place deep below the surface. However, since the permafrost stores huge quantities of carbon, which is released in the [...] thawing will further worsen global warming. In order to collect reliable, up-to-date information on permafrost thawing, the joint project UndercoverEisAgenten was launched today.
for his doctoral thesis, which represents a valuable contribution toward refining simulations of permafrost development: in it, he demonstrates the importance of small-scale landscape characteristics, since [...] a result of thawing. In the future, his findings could help provide a more realistic picture of permafrost thawing.
