Using satellite data, scientists are documenting the inexorable melting of South America’s glaciers and ice fields, with Andean glaciers thinning by nearly three feet a year since 2000. The loss of ice poses a threat to water supplies and agriculture from Bolivia to Chile.
Now, researchers in Germany and France have quantified just how rapidly ice in Peru and throughout the Andes is disappearing. Using high-resolution data generated by satellites and a 2000 Space Shuttle mission to create three-dimensional representations of Andean glacier change over time, the researchers calculated that the area covered by glaciers in Peru shrank by nearly a third from 2000 to 2016.
