 The study projects that by 2081 to 2100, reduced black carbon deposition will decrease the December May average lap-induced radiative forcing in snow over the Northern Hemisphere, and quantify separately the contributions of climate change and lap evolution on future snowpack. The findings suggest that projected lap changes in snow over the Tibetan Plateau will alleviate future snowpack loss due to climate change by 52.1 plus or minus 8 percent and 8.0 plus or minus 1.1 percent at the end of the century for the two scenarios, mainly due to reduced black carbon contamination, leading to a cleaner snow future and its benefits for future water supply from snow melt especially under the Sustainable Development Pathway of SSP 126.
