The thawing of permafrost poses various endangerments to the Arctic environment and the livelihoods of people. An international team examined the social risks for Arctic regions and identified five key risks related to infrastructure, transport and supply, water quality, food security and health.

(Graphic: Alfred-Wegener-Institut) Global warming and the thawing of permafrost not only lead to destabilization of the soil in the permafrost regions of the Arctic, but also to a tendency to increasingly delimit [...] risk assessment is therefore crucial from an economic as well as ecological point of view. The permafrost model CryoGrid, which has been further developed as part of PermaRisk, is intended to help predict

Many landforms throughout the Arctic such as thermokarst lakes, thermoerosion gullies [...] the Arctic. In remote and vast Arctic areas satellite and aerial imagery provide insights into permafrost thaw processes on a regional scale which we would not gain from measurements at the surface. Remote [...] sensing component of the project, therefore, addresses the following research questions: 1. How do permafrost erosion features respond to changes in meteorological conditions? 2. What are the factors controlling
