Greenpeace China activist Zhong Yu shows the 1968 photo of the Middle Rongbuk Glacier to the camera to illustrate the 2km retreat and deterioration of the glacier in just under 40 years. A Greenpeace team from Beijing are at Mount Everest to investigate the melting glaciers caused by dangerous climate change. The Rongbuk Glaciers are one of the prime sources of water feeding into the major rivers of China and India. Glaciers in the Himalaya are receding faster than in any other part of the world as a result of global warming.
