Himalayan glaciers melting twice as fast than before

Cold War-era spy satellite images have shown scientists that glaciers on the Himalayas are now melting 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% a year since 2000, according to a study in the journal Science Advances.
"The amount of ice (lost) 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.
