NASA satellites spot sudden, unprecedented melting across nearly all of Greenland
Posted by satyrikon στο Ιουλίου 24, 2012
WASHINGTON — Scientists say there has been a freak event in Greenland this month: Nearly every part of the massive ice sheet that blankets the island suddenly started melting.
Even Greenland’s coldest area showed melting. Records show that last happened in 1889 and occurs about once every 150 years.
NASA says three satellites saw what it calls unprecedented melting over four days beginning July 8. Most of the thick ice remains. But what was unusual was that the melting occurred over a widespread area.
NASA says the melting area went from 40% of the ice sheet to 97%. Until now, the most extensive melt seen by satellites in the past 30 years was about 55%.
Scientists cannot say yet if the melting is from global warming or natural.
