Two decades ago, this bridge in the Swiss Alps did not exist.
Instead, a glacier allowed hikers to cross the valley.

Where Glaciers Melt Away, Switzerland Sees Opportunity

For hikers looking for a daylong outing in central Switzerland, the Trift Glacier bridge is a popular destination. Its a short gondola ride from the village of Gadmen, followed by a few miles trek up a rocky path overlooking a granite gorge.
Those who successfully fight off a case of nerves the slender cable-and-plank bridge is more than 500 feet long and 300 feet in the air are rewarded with spectacular views. But the Trift Glacier itself is hardly to be seen. Its leading edge has retreated rapidly this century, leaving an opalescent lake behind.
The Trift is a casualty of climate change, one of tens of thousands of glaciers around the world that are shrinking as the earth warms. Melting glaciers are adding to rising sea levels and causing floods, and will eventually mean less water for drinking and agriculture.
But glacial retreat will also have an impact on hydropower, as glaciers shrink to the point where meltwater flows start to decline.
