Place of the Year nominee spotlight: the Arctic [video]
The Arctic sea ice has been seen to be in steady retreat since about 1950, a retreat which has recently sped up with an additional factor of thinning. In summer now there is only a quarter of the volume of ice that there was in summer in 1980. This process shows every sign of continuing, so that the Arctic will be ice-free for part of the year. Obviously we view this as a product of global warming, but why should it concern us in other ways?
