The Tibetan plateau contains tens of thousands of glaciers that provide freshwater to 2 billion people in Asia, and a new report finds the glaciers have warmed more in the last 50 years than in the previous 2,000.

The glaciers feed a number of the largest rivers in the region, including the Yellow and Yangtze in China, the Brahmaputra in India and the Mekong in Southeast Asia, among others.

Temperatures and humidity are likely to continue to climb through this century, the study finds.

In May the same institute that issued the report found that the glaciers on the Tibetan plateau and surrounding areas have shrunk by 15 percent over the past three decades.

The researchers called for government action to protect the region's glaciers and work to reduce human impact, reports Reuters.

In addition to threatening the freshwater supply, shrinking glaciers on the Tibetan plateau will likely lead to more floods and landslides, the report found.
