WMO is the specialized agency of the United Nations dedicated to international cooperation and coordination on the state and behaviour of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources.  WMO provides world leadership and expertise in international cooperation in the delivery and use of high-quality, authoritative weather, climate, hydrological and related environmental services by its Members, for the improvement of the well-being of societies of all nations.

WMO seeks to transform science into services in order to inform understanding of risks, including how climate change is affecting climate extremes, and to help society adapt. Multiple WMO programmes and commissions provide normative and technical support for the observation, prediction, monitoring, and management of extreme temperatures and urban heat islands. WMO supports National Meteorological and Hydrological Services in their work to monitor extreme weather conditions and provide forecasts and advisories of high temperatures and heatwaves to government authorities, health systems and the public.  The World Climate Research Programme studies global climate systems evolution to inform societal understanding of risks. The World Weather Research Programme advances society’s ability to cope with high impact weather by focusing on improving the accuracy, lead time and utilization of weather prediction. WMO also promotes multi-hazard early warning systems to develop and deploy reliable and relevant warnings for protection from extreme weather events. The WMO – World Health Organization Joint office for Climate and Health, focuses on climate services for health, and co-hosts the Global Heat Health Information Network.
