Increased soil carbon release from thawing permafrost through the [...] to understand how the interactions between the vegetation, permafrost and the atmosphere stabilize the forests and the underlying permafrost. A one-dimensional land surface model (CryoGrid) is adapted

In In the framework of MOSES and in cooperation with [...] institutes (AWI-Periglacial Research, GFZ, Geomar) we plan to assess the influence of rapidly thawing permafrost on the distribution of methane in the aquatic environment. Especially the winter situation, the

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

inundation of coastal permafrost areas and their role in the permafrost carbon climate feedback.

Warming permafrost thaws and degrades. Greenhouse gases (GHGs) trapped within or beneath permafrost are released, thus influencing regional and global climate. The carbon cycle of permafrost regions has [...] indicate submarine permafrost thaw. Siberian land craters are a previously unknown permafrost landscape feature. They is evidence of extremely rapid gas release due to permafrost thaw events. Project [...] events on the status of our hydrologic, ecological and socio-economic Earth systems.
