On the occasion of World Meteorological Day, the World Meteorological Organization (WMO) revealed that between 1970 and 2021, weather, climate, and water-related hazards caused more than 2 million deaths and a staggering US$ 4.3 trillion in reported economic losses worldwide. This alarming statistic underscores the need for urgent action to strengthen early warning systems and meteorological services, especially in vulnerable nations.
World Meteorological Day, observed annually on March 23, commemorates the establishment of the WMO in 1950 as a specialized agency of the United Nations (UN). This year, as part of its 75th anniversary celebrations, the WMO stressed the critical importance of scaling up investment in early warning systems to save lives and prevent economic devastation from increasingly frequent and severe extreme weather events.
The Importance of Early Warning Systems
The theme of this year’s World Meteorological Day, “Closing the Early Warning Gap Together,” highlights the stark disparity in global access to weather forecasts and early warnings, especially in low-income and climate-vulnerable countries. Early warning systems are not just a luxury; they are a necessity in today’s climate reality. According to UN Secretary-General Antonio Guterres, these systems represent a sound investment that provides almost a tenfold return by reducing economic losses and saving lives. However, he pointed out that almost half of the world’s countries still lack access to effective early warning systems, which remains “disgraceful” in the digital age.
Timely and accurate forecasts of extreme weather events such as tropical cyclones, floods, droughts, heatwaves, and wildfires can drastically reduce casualties, minimize infrastructure damage, and protect livelihoods. These systems not only help save lives but also enable governments and communities to prepare and respond more effectively to environmental disasters.
Escalating Climate Extremes and Their Impact
The WMO’s latest climate assessment confirms that 2024 has surpassed previous temperature records, primarily driven by greenhouse gas emissions and the accelerating effects of ocean warming and El Niño. As the planet warms, we are seeing more frequent and intense climate events that put lives and economies at greater risk. Alongside soaring temperatures, scientists are witnessing alarming trends such as rising sea levels, glacier retreat, and an increase in extreme weather events. These shifts in the climate system are intensifying the impacts of tropical cyclones, flash floods, wildfires, and droughts.
The UN Secretary-General warned that addressing the climate crisis requires more than just improved weather forecasting. Political will, technological innovation, and increased financing are crucial to mitigating the devastating effects of climate change. Guterres also called for greater collaboration between governments, businesses, and communities, and emphasized the need to scale up financing, including enhancing the lending capacity of Multilateral Development Banks (MDBs), which can support adaptation and resilience-building efforts in vulnerable regions.
Economic Losses from Climate Hazards: A Growing Concern
The global economic toll from weather, climate, and water-related hazards continues to rise. The WMO’s report highlights that the total economic losses between 1970 and 2021 reached a staggering US$ 4.3 trillion. While the number of fatalities has decreased due to improved early warning systems, the financial cost of climate-related disasters remains high. The organization points out that in the last 75 years, billions of dollars in economic losses have been averted due to better forecasting and early action. However, the increasing frequency and intensity of extreme weather events demand even greater investment in disaster resilience and preparedness.
“During the past 75 years, we have brought billions of dollars in added value to the global economy. We have saved billions more in averted economic losses from weather, climate, and water-related hazards,” said WMO Secretary-General Celeste Saulo. “And we have saved hundreds of thousands of lives.” The WMO’s efforts have been central in coordinating global data exchange, which helps guide everything from daily decisions to large-scale infrastructure projects.
Bridging the Gap: Early Warnings for All Initiative
The WMO has made significant progress in expanding early warning systems globally. As of 2024, 108 countries report some capacity for multi-hazard early warning systems, up from just 52 in 2015. However, the WMO acknowledges that many low-income and climate-vulnerable countries still lack access to reliable early warning systems, which remains a critical barrier to saving lives and reducing economic losses in the face of extreme weather.

The WMO and UN are working towards their Early Warnings for All initiative, aiming to ensure that everyone on Earth has access to early warning systems by 2027. This ambitious goal requires not only political will but also technological support, financial investment, and international collaboration. The WMO is calling for increased support for National Meteorological and Hydrological Services (NMHSs), particularly in developing countries, to strengthen forecasting infrastructure and improve data-sharing systems.
The Role of Technology in Transforming Forecasting
The transformative potential of artificial intelligence (AI) and advanced modeling technologies in weather forecasting is another key area of focus for the WMO. These technologies can enhance the accuracy and timeliness of weather predictions, making it possible to issue more precise and localized warnings. However, the WMO stresses that the benefits of these innovations must be shared equitably across all nations, particularly those with limited resources.
“We are more than just weather forecasters,” said Saulo. “The staff of National Meteorological and Hydrological Services are like doctors and nurses – working 24/7 to safeguard and promote public well-being.” As the world faces the growing challenges of climate change, these experts play a crucial role in ensuring the safety and prosperity of communities worldwide.
A Global Call to Action
As the world confronts the growing impacts of climate change, there is an urgent need for global solidarity and investment in weather forecasting and early warning systems. The WMO’s 75th anniversary serves as a reminder that our ability to predict and respond to extreme weather events is not just about protecting lives today but also about safeguarding future generations. To build a more resilient world, nations must come together to ensure that every person, regardless of where they live, is protected by reliable and timely early warning systems.
Through continued investment, innovation, and international collaboration, we can bridge the gap in early warning systems and create a safer, more secure future for all.
