​ECWG & Circumnavigators Joint Dinner: John All: Climate change and civil war on the Mt. Everest massif

  • When: November 18 @ 6:00 pm - 9:00 pm
  • Where: The Cosmos Club; 2121 Massachusets Ave NW, Washington D.C., 20008
  • About the presentation: From 1996 to 2006, civil war engulfed Nepal. The insurgents used the Himalayan national parks as their bases and this had severe social and environmental consequences – consequences that have continued to this day. John has worked in Nepal for many years and summitted Mt. Everest in 2010 without crampons – the only person to have ever done so and lived – and was on Everest during the 2014 icefall and subsequent closure of the mountain by the former Maoist insurgents. John’s research team was in the middle of the icefall that, at the time, had the greatest death toll in Everest history, and one member of his team was killed as they studied climate change impacts on the Everest massif. He will discuss environmental impacts resulting from the Maoist insurgency and how these have reshaped the cultural and social dynamics of the area. These Changes led to the 2014 closure of Mt. Everest and continue to degrade the local ecosystem. 
  • About speaker John All: All, JD, PhD, is a global explorer and geoscientist, specializing in climate change research in remote locations and is the author of Icefall: Adventures at the Wild Edges of our Changing Dangerous Planet. John is the Founding Director of the Mountain Environments Research Institute at Western Washington University. A lifetime Fellow of the Explorers Club and Fulbright Senior Scholar, All is also Executive Director of the American Climber Science Program (, which brings together scientists from many disciplines, along with students and mountaineers, to expand global research at high altitudes. His work is broadly focused on fragile, indicator environments, in particular the world’s highest mountains, where changing climate has profound consequences. He is an advocate for adaptive strategies to cope with changes now occurring and his research is focused on hard science that informs public discourse. His research includes the impact of climate change on endangered species, on subsistence grazing, on fire, and on glacier particulates as they affect water supply. Dr. All works primarily in Peru and Nepal, but has led expeditions on five continents to extreme locations — from deep caves to tropical rain forests; and from remote deserts to the great mountain ranges of Asia and South America. All successfully summitted Mt. Everest, Denali, Artesonraju, Mt. Blanc de Tacul, Alpamayo, El Capitan, and hundreds of other mountains around the world.
