Published Wednesday, April 28, 2021 12:21PM EDT Glaciers are melting faster, losing 31% more snow and ice per year than they did 15 years earlier, according to three-dimensional satellite measurements of all the world s mountain glaciers. Scientists blame human-caused
climate change. Using 20 years of recently declassified satellite data, scientists calculated that the world s 220,000 mountain glaciers are losing more than 328 billion tons (298 billion metric tons) of ice and snow per year since 2015, according to a study in Wednesday s journal Nature. That s enough melt flowing into the world s rising oceans to put Switzerland under almost 24 feet (7.2 metres) of water each year. The annual melt rate from 2015 to 2019 is 78 billion more tons (71 billion metric tons) a year than it was from 2000 to 2004. Global thinning rates, different than volume of water lost, doubled in the last 20 years and “that s enormous,” said Romain Hugonnet, a glaciologist at E

The glacier and the adjacent icefield has lost nearly 16 billion tons (14.5 billion metric tons) of snow and ice since 2000, with 10.7 billion tons of that (9.8 billion metric tons) of that since 2010, Menounos says. And the rate of loss accelerated over the last five years of the study. (Brian Menounos via AP)Brian Menounos/APShow MoreShow Less
