了解亚洲高山冰川对气候变化的长期反应至关重要，因为它们在维持亚洲河流流动方面发挥着重要作用。这里，20世纪60年代以来亚洲高山地区七个气候不同地区的基于卫星的冰川质量平衡时间序列显示，大多数地点的冰川质量损失率持续增加。区域冰川质量收支在天山中北部的−0.40 ± 0.07 m w.a−1到帕米尔东部的−0.06 ± 0.07 m w.a−1之间，具有相当大的时空变异性。2015年后，质量损失率最高的出现在喜马拉雅中部和天山北部，即使是在冰川以前与气候平衡的地区，如帕米尔东部，近年来质量损失也很普遍。夏季气温的升高解释了质量损失的长期趋势，现在似乎甚至在以前对温度和降水都敏感的地区也会导致质量损失。多平台卫星观测记录了亚洲高山地区60年来冰川物质平衡的变化。冰消失率的异质性反映了区域气候差异，但现在冰川消融在整个HMA地区普遍存在，甚至在以前显示出轻微质量增加的地区也是如此。
Knowledge about the long-term response of High Mountain Asian glaciers to climatic variations is paramount because of their important role in sustaining Asian river flow. Here, a satellite-based time series of glacier mass balance for seven climatically different regions across High Mountain Asia since the 1960s shows that glacier mass loss rates have persistently increased at most sites. Regional glacier mass budgets ranged from −0.40 ± 0.07 m w.e.a−1 in Central and Northern Tien Shan to −0.06 ± 0.07 m w.e.a−1 in Eastern Pamir, with considerable temporal and spatial variability. Highest rates of mass loss occurred in Central Himalaya and Northern Tien Shan after 2015 and even in regions where glaciers were previously in balance with climate, such as Eastern Pamir, mass losses prevailed in recent years. An increase in summer temperature explains the long-term trend in mass loss and now appears to drive mass loss even in regions formerly sensitive to both temperature and precipitation. Multi-platform satellite observations document six decades of glacier mass balance variability across High Mountain Asia (HMA). Heterogeneous rates of ice loss reflect regional climatic differences, but ice loss is now pervasive across HMA even in regions formerly exhibiting slight mass gains.
