Arctic to melt by 2040
In 30 years time, the Arctic could be ice-free in summer,
according to scientists from the US National Center for Atmospheric
Research (NCAR), the University of Washington and McGill University in
Montreal. Their simulations suggest that within 20 years, the ice could
be retreating four times more rapidly than has ever been observed,
leaving just a small amount of perennial sea ice along the northern
coasts of Greenland and Canada.
