Less sea ice means e.g. that winds produce larger waves [...] in the Arctic is insulated by water and sea ice, one might assume there was no permafrost there. But guess again: at the bottom of certain shallow coastal seas, the ground is permanently frozen. This type [...] there was so much water frozen in the massive inland ice sheets of Scandinavia and North America that in some places, the sea level was 120 metres lower than today. Where now we see ocean waves, there was

This has a direct impact on Arctic microorganisms as more light is available [...] new production. In addition, ocean warming is leading to changes in the winter mixed layer in the North Atlantic, which has reduced the amount of silica entering the Arctic Ocean in recent decades. This
