Following the deadly mudslide that hit Gyirong Port in southwest China's Xizang Autonomous Region, Chinese expert Yao Tandong, who led the country's second Qinghai-Xizang Plateau scientific expedition, warns that rapid warming is making high-altitude glaciers increasingly unstable – and more likely to collapse. He calls for urgent action: regional risk surveys, closer monitoring of high-risk glaciers and glacial lakes, better modeling of the ice-water-atmosphere interplay, and stronger early-warning and international cooperation.
