Glaciers in the Himalayas have shrunk by as much as a fifth in the last three decades, according to the Nepal-based international Centre for Integrated Mountain Development. This is thought to be the most comprehensive assessment of Himalayan ice melting to date.

David Breashears says the rapidly melting glaciers in the Himalayas are a huge problem because 40 percent of the world's population relies on rivers that are fed by the glaciers. Breashears is trying to draw attention to the melting glaciers through photography. He started with the photographs from historic mountaineers, who captured images of the glaciers, some more than a hundred years ago. Breashears then retraced the mountaineers' footsteps to photograph the same glaciers from the same vantage point. He says that it's personally heartbreaking to see the glaciers change. But he hopes his photos will catch the attention of citizens and governments.

Guest:

  • David Breashears, mountaineer, filmmaker, and executive director and founder of the non-profit Glacierworks
