In April and May 2019, National Geographic and Rolex's Perpetual Planet Expedition to Mt Everest (hereafter 2019 Everest Expedition) undertook the most comprehensive science expedition to the Khumbu (Mt Everest) region and included teams of scientists investigating a range of topics, including glacier change, upward shifts in ecosystems, black carbon deposition on glacier surfaces and snow/ice/water chemistry (Mayewski et al., 2020). As the highest mountain on Earth and the heart of the Himalayan water tower supplying water to hundreds of millions of people (Pritchard, 2019; Immerzeel et al., 2020), the rate and impacts of climate change on Mt Everest (known in Nepal and China as Sagarmatha and Qomolangma, respectively) are of tremendous symbolic and practical significance. Weather conditions on Mt Everest are also a key component of climber safety (Moore and Semple, 2004, 2006; Moore et al., 2010). </p>
