Chinese scientists are combating a glacier's melting by covering it with a blanket

One of China's most-visited glaciers in the Tibetan region, the Dagu Glacier, is now covered with white sheets, also known as geotextiles, in an attempt to slow its melting. Scientists at Nanjing University are leading the effort, and in July installed a white reflective material over 400 square meters of the glacier, located in Sichuan province in southwestern China.
