The polar icecap is retreating and thinning at a record rate
Oct. 26, 2008 (Sunday Times) -- The Arctic icecap is now shrinking at record rates in the winter as well as
summer, adding to evidence of disastrous melting near the North Pole,
according to research by British scientists. They have found that the widely reported summer shrinkage, which this year resulted in the opening of the Northwest Passage, is continuing in the winter months with the thickness of sea ice decreasing by a record 19 percent last winter.
Usually the Arctic icecap recedes in summer and then grows back in winter. These findings suggest the period in which the ice renews itself has become much shorter.
Dr Katharine Giles, who led the study and is based at the Centre for Polar Observation and Modelling at University College London (UCL), said the thickness of Arctic sea ice had shown a slow downward trend during the previous five winters but then accelerated.
