BOULDER, Colorado, April 30, 2007 (ENS) -
Arctic sea ice is melting much more quickly than projected by even the most advanced computer models, a new government funded study has found. Comparing actual ice observations with climate models, the scientists conclude that the Arctic could be seasonally free of sea ice as early as 2020.
Scientists at the National Center for Atmospheric Research and the University of Colorado's National Snow and Ice Data Center have demonstrated that the Arctic's ice cover is retreating more rapidly than estimated by any of the 18 computer models used by the Intergovernmental Panel on Climate Change in preparing its 2007 assessments.
