Climate change comes to the mountains of Peru

Climate change brought water to the coastal deserts of Peru, letting farms there flourish for decades. But now the rapidly-melting glaciers have shrunk too much — and as the water disappears, the farms it fuels also might, writes Nicholas Casey for the New York Times.

Why it matters: These ice caps support over 100,000 acres of farmland, and the 8,000 tons of produce grown there is shipped as far away as China and Denmark. Before farmers started irrigating the desert with meltwater, "the land was empty and people went hungry," farmer Miguel Beltrán tells the Times. Today, hundreds of thousands of people rely on the water to live and work.
