Short summary
We show that black carbon aerosol pollution is likely the dominant factor in causing the accelerated retreat of snowpack in Himalayas. The simulated snow fraction and surface albedo change at the surface, as well as the enhanced warming at higher elevations, are remarkably similar to observations in past decades. The reason for the model's ability to simulate the observed trends is that we replace the model-simulated black carbon forcing with one that is constrained by observations.
