The Arctic is heating at twice the rate of the rest of the world. Why? The albedo effect. This video explains what that effect is and what will happen if the melting trends continue. Well worth your time.

The Arctic’s glaciers, including those of Greenland’s vast ice cap, are retreating. The land is thawing: the area covered by snow in June is roughly a fifth less than in the 1960s. The permafrost is shrinking. Alien plants, birds, fish and animals are creeping north: Atlantic mackerel, haddock and cod are coming up in Arctic nets. Some Arctic species will probably die out.  Perhaps not since the 19th-century clearance of America’s forests has the world seen such a spectacular environmental change. It is a stunning illustration of global warming, the cause of the melt. It also contains grave warnings of its dangers. The world would be mad to ignore them.
