human activity in the Arctic takes place along permafrost coasts. These coasts have become one of the most dynamic ecosystems on Earth because permafrost thaw is now exposing them to rapid change: change [...] fates of organic matter released from thawing coastal and subsea permafrost; (2) assess what risks are posed by thawing coastal permafrost, to infrastructure, indigenous and local communities and people’s [...] system. NUNATARYUK is a H2020 project that investigates the impacts of thawing coastal and subsea permafrost on the global climate, and develops targeted and co-designed adaptation and mitigation strategies

Forever frozen? Permafrost in the Arctic In story 1 students receive basic knowledge about permafrost and the consequences of climate change for permafrost. The importance of permafrost research is explained [...] changed in the Arctic over the last decades? What is permafrost? How does thawing permafrost affect the Arctic environment? How does thawing permafrost affect Arctic infrastructure? The main goal of this [...] and learn about permafrost in the Arctic and the effect of degrading permafrost on the Arctic environment. The focus lies on the complex interactions between men, nature and permafrost and resulting conflicts

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
