英文摘要	Andean glaciers are among the fastest shrinking and largest contributors to sea level rise on Earth. They also represent crucial water resources in many tropical and semi-arid mountain catchments. Yet the magnitude of the recent ice loss is still debated. Here we present Andean glacier mass changes (from 10 degrees N to 56 degrees S) between 2000 and 2018 using time series of digital elevation models derived from ASTER stereo images. The total mass change over this period was -22.9 +/- 5.9 Gt yr(-1) (-0.72 +/- 0.22 m w.e.yr(-1) (m w.e., metres of water equivalent)), with the most negative mass balances in the Patagonian Andes (-0.78 +/- 0.25 m w.e. yr(-1)) and the Tropical Andes (-0.42 +/- 0.24 m w.e. yr(-1)), compared to relatively moderate losses (-0.28 +/- 0.18 m w.e. yr(-1)) in the Dry Andes. Subperiod analysis (2000-2009 versus 2009-2018) revealed a steady mass loss in the tropics and south of 45 degrees S. Conversely, a shift from a slightly positive to a strongly negative mass balance was measured between 26 and 45 degrees S. In the latter region, the drastic glacier loss in recent years coincides with the extremely dry conditions since 2010 and partially helped to mitigate the negative hydrological impacts of this severe and sustained drought. These results provide a comprehensive, high-resolution and multidecadal data set of recent Andes-wide glacier mass changes that constitutes a relevant basis for the calibration and validation of hydrological and glaciological models intended to project future glacier changes and their hydrological impacts.
