Every year we are told by Nobel Prize winners, climate scientists and environmental activists that the Arctic will be ice-free that year. They are flat-earthers.
It is impossible for the Arctic to be ice-free under current climate conditions, because the Earth is round. Because of the high albedo of clouds and ice and the low angle of the sun, north of 80N they don’t get enough solar energy to melt that much ice. The prevailing winds also jam the ice up against the Canadian Coast, and make it very thick.
