  In April and May 2019, as a part of the National Geographic and Roxel
Perpetual Planet Everest Expedition, the most interdisciplinary scientific ever
was launched. This research identified changing dynamics, including emergent
risks resulting from natural and anthropogenic change to the natural system. We
have identified compounded risks to ecosystem and human health, geologic
hazards, and changing climate conditions that impact the local community,
climbers, and trekkeers in the future. This review brings together perspectives
from across the biological, geological, and health sciences to better
understand emergent risks on Mt. Everest and in the Khumbu region.
Understanding and mitigating these risks is critical for the ~10,000 people
living in the Khumbu region, as well as the thousands of visiting trekkers and
the hundreds of climbers who attempt to summit each year.
