Short summary
Tree-ring isotope records from the central Himalaya provided a basis for previously lacking regional multi-century glacier mass balance (MB) reconstruction. Isotopic and climate coherency analyses specify an eastward-declining influence of the westerlies, an increase in east–west climate heterogeneity, and an increase in ice mass loss since the 1960s. Reasons for this are attributed to anthropogenic climate change, including concurrent alterations in atmospheric circulation patterns.
