World Meteorological Day

Our climate is changing, and will continue to change over the coming decades as more and more heat-trapping greenhouse gases emitted by human activities accumulate in the atmosphere. Meanwhile, scientific advances are making it possible to produce increasingly useful climate information and services to support climate resilience, adaptation and mitigation. The World Meteorological Organization and the global network of National Meteorological and Hydrological Services have a major role to play in providing the scientific observations, research and operational climate services that society will need in order to face the future.

The United Nations' World Meteorological Day is annually held on or around March 23 to remember the World Meteorological Organization's establishment on that date in 1950. Many different activities and events are organized, including conferences, symposia and exhibitions for meteorological professionals, community leaders and the general public. This year's theme is "Hotter, drier, wetter. Face the future."
