Shortly after midnight Tuesday, 5,000 meters up in the Himalayas just south of India’s border with China, a slight shift started an avalanche.

The effects of climate change within the world’s most dramatic mountain range have snapped together like deadly clockwork — and hundreds of other ticking time bombs dot the landscape.
