The 2019 study, spanning 40 years of satellite observations across India, China, Nepal and Bhutan, indicates that climate change is eating the Himalayas’ glaciers, the researchers said.

The study, published in the journal Science Advances in June 2019, shows that glaciers have been losing the equivalent of more than a vertical foot and half of ice each year since 2000 — double the amount of melting that took place from 1975 to 2000.
