Global: Arctic may be ice-free within 30 years

Sea ice in the Arctic is melting at a record pace this year, suggesting warming at the north pole is speeding up and a largely ice-free Arctic can be expected in summer months within 30 years. The area of the Arctic ocean at least 15 per cent covered in ice is this week about 13.6 square kilometres - lower than the previous record low set in 2007 - according to satellite monitoring by the US National Snow and Ice Data Centre (NSIDC) in Boulder, Colorado. In addition, new data from the University of Washington Polar Science Centre, shows that the thickness of Arctic ice this year is also the lowest on record.
