China and Nepal built an early warning system for melting glaciers in Himalayas. Does it work?

Key Points:

• Chinese and Nepalese scientists have developed a cross-border early warning system to monitor Himalayan glacial lake outburst floods, which has issued timely alerts over recent years and helped prevent casualties.
• A recent disaster may have been triggered by a glacial rock collapse, though it is unclear if the China-Nepal early warning system detected any anomalies or issued warnings before the event.
• A paper published by the project team highlighted several successful early warning systems, including those for ice avalanches in the Yarlung Tsangpo River area and glacial lakes in the China-Nepal basin, with seven warnings issued so far.
• Experts note that high-altitude ice-rock avalanches release significantly more energy and cause more destruction than typical glacial lake outburst floods.
• The South China Morning Post has sought comments from lead author Wang Weicai and the Chinese Academy of Sciences regarding the latest incident and the early warning system's role.
