The glaciers of the Tian Shan mountain range in northwestern China had lost about a quarter of their ice mass since the 1960s when this image was captured, in November 2016. Source: ESA Advances in satellite technology reveal ice masses in Alaska and Asia have lost 4% of their volume in less than a decade. By Laura Millan Lombraña and Sam Dodge Glaciers in the Gulf of Alaska and in Asia’s High Mountain region are melting so fast that the changes can be seen from space, with the shrinkage now measured in years rather than decades. Just over 4% of the ice volume in these two regions disappeared between 2011 and 2019, according to the first study to monitor large-scale changes in glacier thickness, mass and sea-level contribution. Researchers used radar altimetry technology embedded in a European Space Agency satellite, which they say is the first step toward year-round […]
