The polar and sub-polar regions around the North Pole represent an early warning system for global climate change. Hardly any other region in the world

Specially adapted [...] tiny particles can then easily be ingested by sea life and accumulate in the food chain, as far up as fish. We have found high levels of microplastic in sea ice. The aim of our research is now to gain a

marine deposits, the scientists could demonstrate that the Arctic Ocean as well as the Nordic Seas did not contain sea-salt in at least two glacial periods. Instead, these oceans were filled with large amounts [...] amounts of freshwater under a thick ice sheet. This water could then be released into the North Atlantic in very short periods of time. Such sudden freshwater inputs could explain rapid climate oscillations
