SYDNEY (IDN) – The latest evidence on climate change demands a radical reappraisal of our approach. The Arctic has been warming 2-3 times faster than the rest of the world, reducing the area and volume to levels never previously experienced.
Some 80% 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 which were not expected to occur for another 100 years. More concerning, the Greenland ice sheet this year has seen unprecedented melting and glacial ice calving, adding to a trend which will substantially increase sea level rise.
