Arctic lost part of its perennial sea ice in 2005: NASA

WASHINGTON (AFP) – Global warming may already be having an effect on the Arctic which in 2005 only replaced a little of the thick sea ice it loses and usually replenishes annually, a
NASA study said Tuesday.

Scientists from the US space agency used satellite images to analyze six annual cycles of Arctic sea ice from 2000 to 2006.


Sea ice is essential to maintaining and stabilizing the Arctic’s ice cover during its warmer summer months.

But “recent studies indicate Arctic perennial ice is declining seven to 10 percent each decade,” said Ron Kwok from NASA’s Jet Propulsion Laboratory in Pasadena, California.
