Spy satellite images are showing scientists that glaciers on the Himalayas are now melting about twice as fast as they used to.
WASHINGTON — Cold War era spy satellite images are showing scientists that glaciers on the Himalayas are now melting about twice as fast as they used to.
The Asian mountain range, which includes Mount Everest, has been losing ice at a rate of about 1 percent a year since 2000, according to a recent study in the journal Science Advances. "The amount of ice is scary but what is much more scary is the doubling of the melt rate," said Josh Maurer, a glacier researcher at Columbia University's Lamont Doherty Earth Observatory and lead author of the study.
The Himalayas, part of an area that is referred to as"The Third Pole" because it has so much ice, has only 72 percent of the ice that was there in 1975. It has been losing about 8.3 billion tons of ice a year, compared 4.3 billion tons a year between 1975 and 2000, according to the study released Wednesday.
