What happens if Mount Everest loses all of its snow and ice?

No place on earth can escape the effects of climate change, not even Mount Everest. The highest glacier on the world’s tallest mountain — the South Col Glacier — is rapidly disappearing. A new University of Maine-led study found that the glacier is losing several decades of ice and snow accumulation annually due to human-induced climate change. These findings are the latest from the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition, led by UMaine Climate Change Institute director Paul Mayewski. In this episode of “The Maine Question,” Mayewski and UMaine Ph.D. candidate Mariusz Potocki, both co-authors of the new study, elaborate on the findings and their implications for mountaineering and the glacier stored water on which more than 1 billion people depend to provide melt for drinking water and irrigation. They also describe what it takes to conduct research on the rooftop of the world.
