This water will flow thousands of miles, eventually feeding people, farms, and the natural world on the vast, dry Indus plain. Many of the more than 200 million people in the downstream basin rely on water that comes from this stream and others like it.
But climate change is hitting those high mountain regions more brutally than the world on average. That change is putting the “water towers” like this one, and the billions of people that depend on them, in ever more precarious positions. New research published Monday in Nature identifies the most important and vulnerable water towers in the world.
