reflect in detail processes in the ocean, which have a major influence on the climate. In response, the AWI has developed a special ocean model (FESOM), which simulates e.g. ocean currents and sea ice. For their [...] All around the world, there are natural climate archives – the sediments on the ocean floor, ancient ice in the Arctic and Antarctic, wood for tree-ring analyses, and more. These archives contain what [...] computer programmes used to simulate reality: the motion of air masses, radiation from the sun, and ocean currents – they’re all climate-relevant processes that, with the aid of mathematical formulas, can

Under conditions of further warming and acidification of the ocean, Atlantic cod and its arctic relative polar cod would be forced to look for new habitats in the far north. Their [...] dwindle. If so, this could be disastrous, as the polar cod is the most important food source for Arctic seals and seabirds. In addition, fishers could lose the world’s most productive area for catching

show, part of the biomass released becomes trapped in deep sinks on the ocean floor off the Arctic coast – where it is protected from microbial decomposition. The outcomes of their analyses are intended [...] Permafrost
The Arctic is warming more strongly than any other region on Earth, which leads to serious erosion of coasts where organic matter was frozen in the permafrost for thousands of years. Once [...] Once eroded material is released into the ocean, microorganisms break down ancient plant remains, releasing sizable quantities of greenhouse gases. Yet, as the latest analyses conducted by AWI experts show
