EVENT DOSSIER
As global warming continues to intensify, the rate of glacier melting has significantly accelerated. Recent monitoring data shows that glaciers in many areas are experiencing large-scale disintegration, turning ice collapse events from rare occurrences into a relatively common natural risk. This trend not only threatens the safety of coastal communities but may also trigger chain environmental effects such as rising sea levels. Currently, the international community and relevant scientific institutions are working to strengthen monitoring of glacier dynamics, evaluate disaster warning mechanisms, and explore adaptive strategies to mitigate the potential crises posed by normalized ice collapses.
西藏吉隆县泥石流灾害发生后，第二次青藏科考队与西藏自治区科学技术厅等第一时间联合研判。中国科学院院士、第二次青藏科考队队长姚檀栋解读称，青藏高原是全球气候变化的敏感区和“放大器”，其升温速率明显高于全球平均水平。此次尼泊尔一侧发生的冰崩灾害属于海洋性冰川失稳所致，该类冰川对气候变化反应敏感，致灾后果强且频率高。随着气候变暖加剧，冰川融化导致下渗，引发松床垮塌或基岩滑动，冰崩已成为常态化风险。针对全球冰冻圈安全风险上升问题，专家建议深化国际合作，推进全球冰冻圈治理，加强调查、监测、预警及灾害防治工作。联合国已将 2025 年至 2034 年定为“冰冻圈科学行动十年”，旨在加强相关研究、监测与应对。
