This coverage is unparalleled in comparison with all previous and

processes between the atmosphere and the ocean. The observed sea ice changes affect the climate and ecosystem, extending to our latitudes. The decline of Arctic sea ice in area and volume is one of the [...] Observer | 28.07.2020 Sea ice extent in the Arctic reaches historical low in July Find out more > Carbon Brief | 18.11.2019 Inside MOSAiC: How a year-long Arctic expedition is helping climate science Find [...] future, we will focus more on studying the physical snow and ice properties in interaction with the ocean and atmosphere, but also study linkages to the ecosystem.

Survey-like studies on coastal erosion in the Arctic exist, but a comprehensive understanding of local processes is lacking [...] Coastal Permafrost Profile About 34% of the world's coasts are affected by Arctic permafrost and are particularly sensitive to climate change. The frozen bluffs lose the cohesion provided by the permafrost [...] seawater and are instantly washed away by incoming waves. In the course of the expected warming in the Arctic, which is estimated to be about two to four times as high as the global average, favourable conditions
