Arctic sea ice is shrinking at a rate much faster than scientists ever predicted and its collapse, due to global warming, may well cause extreme weather this winter in North America and Europe, according to climate scientists. Last month, researchers
The new data shows that sea ice extent in the Arctic has already shrunk to 70,000 square kilometres below the previous record low in2007, with two or three weeks in the melt season still left to go.The six lowest ice extents in the satellite record

UK scientists combined results from Cryosat, which uses radar to measure ice thickness, with data from Nasa's IceSat, which uses lasers. Their preliminary analysis suggests an annual ice loss of up to 900 cubic km a year from 2004...But the new
Arctic sea ice melt in 2012 is even greater than the records set in 2007. Photgraph: Steven J Kazlowski/Alamy With about a month and a half remaining in the Arctic melt season, sea ice cover continues to decline at a rapid pace, and is currently on
