their new homes, creating a host of new water bodies. This could accelerate the thawing of the permafrost soils, and therefore intensify climate change, as an International American-German research team

Permafrost
Experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), the Humboldt-Universität zu Berlin (HU) and the University of Oslo have determined that much [...] much of the permafrost that is currently still very cold might disappear by the end of the century. What’s new about their simulations: the inclusion of thermokarst processes. The outcomes of the study

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

A process-based model reveals that how much carbon peatlands may lose—or accumulate—in the future varies from place to place.

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.
