Recent Wetting and Glacier Expansion in the Northwest Himalaya and Karakoram

Abstract Hydroclimatic variability driven by global warming in the climatically vulnerable cold semi-arid to arid northwest (NW) Himalaya is poorly constrained due to paucity of continuous weather records and annually resolved proxies. Applying a network of annually resolved tree-ring-width chronolo...
