Canary in the coal mine – Mount Wheeler

As the climate changes, disappearing snow and ice on Wheeler Peak — Nevada’s second-highest mountain — raise concerns about the future of water in the state, for which the glacier plays an integral role.

Climate change is expected to hit alpine ecosystems like Mount Wheeler’s hardest, said Steven Mietz, superintendent of Great Basin National Park.

“The region could be a baseline for measuring how nature reacts to global warming. The glacier is a canary in a coal mine,” he said.
