A curious thing has happened over the 2009 – 2010 winter season – Arctic sea ice has rebounded to near normal levels. Long pointed to as a sign of the impact of global warming, the extent of sea ice had been shrinking in recent years.
According to the National Snow and Ice Data Center (NSIDC), the maximum extent for Arctic sea ice was reached on March 31st. This is the latest date maximum extent has been reached since 1979 when satellites began measuring the Arctic Ice.
The center said that it was thought the sea ice was done growing around the beginning of March. However, late season winter storms over the Bering and Barents Seas allowed it to continue to enlarge. “By the end of March, total extent approached 1979 to 2000 average levels for this time of year,” the NSIDC said.
