Himalayan glaciers are melting and retreating at their edges because of global warming. But they also conceal a more ominous effect of climate change: they are deflating. They are losing internal ice mass to melting, which can substantially hasten their disappearance. Scientists have recently captured real-time video showing a glacier purging its own meltwater, and at rates far faster than the experts had imagined.

To obtain the video, Ulyana Horodyskyj, a geologist at the University of Colorado at Boulder, climbed to 5,000 meters on the Ngozumpa Glacier in Nepal [below].
