As a traveler, I see signs of climate change everywhere. Europe is grappling with unpredictable weather in lots of different ways — and in the Alps, that means artificial snow.

It’s summer here now, and this area is filled with hikers. But in the winter, this is ski country — and the local economy depends on ski tourism. All across the Alps, ski slopes are being plumbed for artificial snow. Take a look with me now at some of the reservoirs that supply water to this mountain’s snowmaking machines.
