... wrong. In 1982 it was proposed that the Arctic might become ice-free in summer in 2200. It is more likely to occur by 2020. The heating of the Earth’s surface has paused from time to time, due to albedo changes induced by atmospheric pollutants and by heat storage in the ocean interior. Over the las ...
