Three climbers died over the weekend while descending from the summit of Mount Everest, MSNBC reported. Eberhard Schaaf, 61, of Aachen, Germany, died of altitude sickness while climbing with an expedition to remove decades-old garbage from the mountain. Nepalese officials said the other two deaths were a 32-year-old Nepal-born woman living in Canada, Shriya Sha, and a Korean, Song Won-Bin. Theirs were the latest deaths since two Sherpas earlier this season. As least 236 people have died since climbing Everest since 1950, according to MSNBC. This season is especially dangerous because of minimal snowpack and warm temperatures, according to the group Himalayan Experience, which has canceled expeditions over safety concerns.
