The World Meteorological Organization (WMO) is celebrating its 75th anniversary, and its importance is clearer than ever. Global leaders and experts recently emphasized how crucial the WMO’s role has become in saving lives and boosting economies through better weather and climate information.
The celebrations kicked off on World Meteorological Day on March 23 and wrapped up with a special Congress in October. At this event, WMO Secretary-General Celeste Saulo called for better early warning systems to help communities prepare for extreme weather. UN Secretary-General António Guterres backed this initiative, describing WMO as a reliable source of information as we face climate challenges.
“WMO is more vital now than at any time in history,” Guterres said. As we approach significant temperature increases, early warnings become essential. This was a central theme at COP30 in Belém, Brazil, where discussions about climate impacts and strategies took center stage. The year 2025 is projected to be one of the warmest on record, highlighting the urgent need for action.
Extreme weather has led to tragic losses and significant economic damage, making efficient early warning systems even more critical. AI technology is emerging as a game-changer in this area. It promises to improve weather forecasting, ensuring vital information reaches those who need it most. The recent World Meteorological Congress adopted a resolution to guide the use of AI in forecasting activities.
When WMO was founded in 1950, it lacked essential technologies like satellites and supercomputers. Saulo pointed out how far we’ve come and stressed the importance of sharing meteorological data between countries. This collaboration is vital for tackling global weather and climate issues.
“WMO saves lives and money daily,” Saulo noted. It plays a key role in aviation safety, flood protection, drought management, and climate monitoring. This spirit of “data diplomacy” showcases how shared knowledge can unite nations.
Throughout the year, WMO highlighted its accomplishments through various activities, including dedicated bulletins and celebration events in Geneva, even featuring a drone show that illustrated its history and achievements.
Looking ahead, WMO has adopted its first Youth Action Plan to empower young scientists in meteorology and climate studies. Created through extensive consultations with over 200 participants, this plan aims to involve youth in decision-making processes regarding climate and weather issues.
Despite its growing significance, Saulo pointed out a troubling trend: funding for meteorological services is not keeping pace with the demand. While these services are crucial for development and disaster response, short-term budget limitations often hinder their effectiveness.
As WMO prepares for the next 75 years, Saulo outlined three guiding principles: investing in science and building trust, promoting global public goods, and advancing adaptation and equity. “The partnerships we build today will pave the way for future successes,” she said.
As we face mounting climate challenges, the WMO’s role as a global leader is essential. Its focus on collaboration, youth involvement, and innovative technology could be a beacon of hope in addressing the climate emergency.
