Arctic sea ice melting faster than most scientists project: study

Arctic sea ice is melting three times faster than many scientists have projected, U.S. researchers reported Monday, just days ahead of the next major international report on climate change.
Scientists at the National Center for Atmospheric Research and the University of Colorado in Boulder, using actual measurements, concluded Arctic sea ice has declined at an average rate of about 7.8 per cent a decade between 1953 and 2006.
