Since the ocean floor in the Arctic is insulated by water and sea ice, one might assume there was no permafrost there. But guess [...] latitudes of the Arctic and Antarctic, a minor rise is enough to set off thawing. To FAQ element Why are permafrost coasts increasingly collapsing?

snow isn’t just snow. There are clear differences if you compare, e.g., the Arctic and Antarctic. While the snow on the Arctic sea ice is completely melting over the course of the year, and so-called meltwater [...] effectively it insulates, and as such reduces the transfer of heat from the ocean to the atmosphere. However, the less warmth the ocean gives off, the thinner the sea ice remains.
