Ian Dunlop: Four-degree rise demands 90-degree rethink
Climate change has moved into a new and dangerous phase. The Arctic has been warming two to three times faster than the rest of the world. In the past few weeks, melting of the Arctic sea ice has accelerated dramatically, reducing the area and volume to levels never previously experienced. About 80 per cent of the summer sea-ice has been lost since 1979; on current trends the Arctic will be ice-free in summer by 2015 and ice-free all year by 2030 - events that were not expected to occur for another 100 years. More concerning, the Greenland ice sheet this year has had unprecedented melting, adding to a trend that will substantially increase sea levels.
