In 2022, the United Nations General Assembly adopted a resolution declaring 2025 the International Year of Glaciers' Preservation (IYGP). This resolution also established March 21 as the annual World Day for Glaciers and World Water Day, starting in 2025. The goal of these observances is to increase global awareness of the essential role glaciers, snow, and ice play in the climate system and to highlight the economic, social, and environmental consequences of changes in the Earth's cryosphere.

To mark the beginning of IYGP 2025, UNESCO and the World Meteorological Organization, in collaboration with global partners, are coordinating an event on January 21, 2025, in Geneva, Switzerland, with online participation available. Learn more about this event and watch the Introduction video.
