Photo taken with a mobile phone shows a view of the East Rongbuk glacier on Mount Qomolangma, May 6, 2022. The new comprehensive scientific expedition on Mount Qomolangma, as part of China's second scientific research survey of the Qinghai-Tibet Plateau, is the country's first scientific research above an altitude of 8,000 meters on the peak. More than 270 scientific research members from five teams are participating in the expedition. The glacier and pollutant research team led by Kang Shichang, a researcher with the Northwest Institute of Eco-Environment and Resources under the Chinese Academy of Sciences (CAS), will monitor pollutants, the Rongbuk glacier and ice lake changes, as well as the greenhouse gas emissions from rivers and lakes covering the high-altitude area from the Mount Qomolangma base camp to the East Rongbuk glacier.
