I have read many mountaineering books and I am a biology teacher, so you would think I would have thought about the impact of global warming on places like Mount Everest, right? Wrong. Fact is, Mount Everest like all glacier covered mountains is melting. John All worked as a research scientists collecting data about global warming from all sorts of places - the Andes, Belize, Africa and of course, the Himalayas.
It was the ice fall avalanche that chased him off Everest to a much humbler mountain after 16 sherpas were killed on Everest. On Himlung, he decided to make some coffee and fell into a crevasse. He was certain he was going to die, his video went viral on face-book and triggered his rescue.
