Water crisis looms as Himalayan glaciers melt
"About 67 percent of the nearly 12,124 square miles of Himalayan glaciers are receding and in the long run as the ice diminishes, glacial runoffs in summer and river flows will also go down, leading to severe water shortages in the region."
Basically 40% of humanity depends on Himalayan rivers. It will take regional cooperation to address the expected apocalypse, which might not be possible to avert.
