In April of 2019, a team of scientific researchers and documentarians arrived at Mount Everest’s southern basecamp in Nepal to measure the impacts of climate change and human activity on the world’s tallest mountain. The pollution team, led by University of Maine Assistant Professor Kimberley Miner, lugged heavy scientific equipment up the most popular ascent route. At each stop, Miner's team took samples of snow, the same snow climbers were boiling and drinking, the same snow that melted each summer and provided water for people living in the valleys below.
