The United Nations observe World Day for Glaciers on March 21, 2025, with the first celebration in 2025. In December 2022, the UN General Assembly adopted a resolution proclaiming March 21st as the World Day for Glaciers, alongside declaring 2025 as the International Year of Glaciers’ Preservation. This initiative aims to draw attention to the vital role of glaciers, snow, and ice in the Earth’s climate system and water cycles.
The observance highlights the economic, social, and environmental consequences of the rapid melting of glaciers and its broader impact on the cryosphere. It also provides an opportunity to share best practices, scientific knowledge, and collaborative strategies to address the challenges posed by these changes, including water scarcity and rising sea levels. World Day for Glaciers calls for global action to protect these critical ecosystems and support communities most affected by glacial loss.
