2019 Everest Environments Expedition

2019 Everest Environments Expedition

Changing Climate, Changing Lives


Interested in climbing Mt. Everest or curious about the Sherpa people?  Wonder about climate change and the tallest mountain on earth?

The  Mountain Environments Research Institute and  American Climber Science Program and will be working in Nepal at Mt. Everest and Lhotse in Spring, 2019. We will be collecting a variety of environmental data to compare with our on-going research in the Cordillera Blanca in Peru and past research on Mt. Everest. Two Western professors and two Western students will be part of the ten person team.

The expedition will be carried out at high elevation, including an ascent to the summits of Everest and Lhotse. We will all be working together to gather data, haul loads, and climb the mountain. John All is the expedition and scientific leader. Scientists and graduate students from the University of Colorado and Western Washington University will be working with Nepali graduate students from Tribhuvan University to investigate climate change impacts on the local Himalayan communities and environment.

Our US, European, and Nepali science team includes Eric DeChaine, Director of the Pacific Northwest Herbarium at Western Washington University, Sébastien Lavergne, Laboratoire d'Ecologie Alpine, Université Grenoble Alpes, France, and Kamal Humagain, State University of New York, Potsdam. Our local partners in Nepal include Dr. Ram Kailash Prasad Yadav chair of the Central Department of Botany at T.U., and Dr. Jyoti Prasad Gajurel, an Ecological Consultant at the Nepal Rural and Advancement Committee in Kathmandu.

Expedition Research and Outreach

  • Ecology: We will collect vegetation data in the lower elevation areas early in the expedition, to link with satellite imagery and compare to past expeditions and published studies.

  • Glacial Retreat and Air Quality: Once we are settled into base camp, we will sample snow on the glacier for particulates (black carbon and dust), and we will continue taking samples all the way to the summits on Everest and Lhotse.  

  • Meteorology: We monitor ambient CO2 levels and meteorological conditions in our sample locations and at base camp.  

  • We will work with Sagarmatha National Park, Tribhuvan University in Kathmandu, and others to disseminate our findings.
