KATHMANDU, Nepal, Aug. 15 (UPI) -- The glacier-filled Tibetan plateau has warmed more over the last 50 years than it has in the preceding 2,000, according to researchers in China.
The Tibetan plateau is covered with tens of thousands of glaciers. The interlinked sheets of ice source the headwaters of the some of the world's largest rivers -- the Yellow and Yangtze in China, the Brahmaputra in India and the Mekong in Southeast Asia -- providing clean drinking water for more than 2 billion people. The snow-covered plateau is sometimes called the "roof of the world."
