On the 18th, UNESCO held a series of activities called the "Decade of Action for Cryosphere Science" at its headquarters in Paris. According to UNESCO, the cryosphere includes glaciers, ice sheets, permafrost, sea ice, and snow cover, containing approximately 70% of the Earth's freshwater resources, but its size is rapidly shrinking. The loss of the cryosphere has already had an impact on global water security, ecosystems, infrastructure, and more. In response, the United Nations has designated the period from 2025 to 2034 as the "Decade of Action for Cryosphere Science", led by UNESCO, to strengthen research, monitoring, education, and public action on changes in the cryosphere. In addition to the "Decade of Action for Cryosphere Science" thematic forum, the activities on the 18th also include the closing ceremony of the "2025 International Year of Glacier Conservation" and the World Water Day event. French glaciologist Heidi Cevestre said at a special forum that the "Decade of Action for Cryosphere Science" calls on all parties to pay attention to the issue of cryosphere loss and to do a good job in promoting it in plain language. "The loss of the cryosphere is not only a matter of water security, but also related to migration, agriculture, infrastructure and other issues." Yao Tandong, an academician of the CAS Member who attended the event, said in an interview with Xinhua News Agency that international cooperation is very important for cryosphere research. China has accumulated successful experience in international cooperation in the past in the research of the "third pole region", which is of great value for the development of the "cryosphere scientific action decade" in the future. In the future, China will continue to promote related work around high-level research and international cooperation, and continue to make efforts through special projects, platform construction, and global scientific research networks. John Pomeroy, Chairman of the Special Management Committee for the "Decade of Cryosphere Science Action", said at the forum that there are still shortcomings in global cryosphere related prediction models, such as insufficient resolution and inadequate characterization of key processes in mountainous and polar regions. In the future, a comprehensive prediction system with high resolution, scalability, and deep integration with observation systems should be developed based on the actual needs of society.
