If you want to figure out how climate change is affecting the world’s highest places you have to go up there yourself to find out. So scientists like John All, who directs Western Washington University’s Mountain Environments Research Institute, spend weeks at a time at the world’s highest elevations to collect pollution samples, flora specimen, and to examine ice. It’s a dangerous place to conduct research that requires a special kind of adventurous researcher. Check out Gizmodo’s terrific profile of All and his team’s crucial work in the Himalaya at 26,000 feet-plus. Photo: McKay Savage
