Glaciers and glacial lakes are important indicators of global climate change. The accelerated retreat of glaciers and expansion of glacial lakes under a warming climate pose a high risk of glacial lake outburst floods (GLOFs), which can have catastrophic impacts on downstream communities and infrastructure. The Himalayas, the world’s highest mountain range and home to extensive glaciers and glacial lakes, are particularly vulnerable to these changes and hazards. 

Prof. KANG Shichang, Chair of the International Geographical Union (IGU) Commission on Cold and High Altitude Regions (CHAR), led a scientific expedition in Xigaze City, southwest China’s Xizang Autonomous Region, from August 3 to 10, 2026. The expedition involved young Chinese scientists and students and included field investigations of multiple glaciers and glacial lakes in the region. During the expedition, the research team investigated the formation and evolution of glacial lakes and assessed potential risks of GLOFs. The research team also evaluated potential sites for early-warning monitoring, providing a scientific basis for future monitoring and risk assessment.

Beyond its scientific objectives, the expedition provided young scientists and students with valuable experience in high-altitude field research. The observation data and experience gained during the expedition will support continued research and help advance scientific understanding of cryospheric change and associated hazards in high-altitude regions.
