Short summary
Mountain glaciers are important freshwater reservoirs. Quantifying their loss is essential for forecasting water availability. While glacier retreat is well studied in many regions, glacier loss on the Nevados de Chillán volcanic complex in south-central Chile remains uncertain. Using satellite and drone images, we find all 28 glaciers on Nevados de Chillán lost volume over the past 7 decades, with melt rates accelerating markedly since 2000.
