World Meteorological Organization

As we tackle unpredictable weather across the world, a #throwback interview with WMO Deputy Secretary-General Ko Barrett reminds us that: “Reliable forecasts don’t happen by accident. No country can know the world’s weather on their own.” Weather and climate do not stop at borders. Through the World Meteorological Organization, countries share observations and data that make early warnings and forecasts possible. International cooperation is not optional. It is the foundation of safety, resilience, and informed decisions. Read the interview: https://lnkd.in/eM5u3zbC

Climate science is the foundation of effective climate action in an era of accelerating impacts, growing vulnerability, and rising economic costs. This was my message to the IPCC Bureau meeting today taking place at WMO headquarters in Geneva today. The World Meteorological Organization and UN Environment Programme are the proud parents of the IPCC. ✅ Continued scientific integrity, inclusivity, and global cooperation must remain at the heart of the IPCC process. ✅ The credibility of rigorous and policy-relevant climate science is one of our strongest collective assets and we must continue to safeguard and strengthen its role.

Reliable data is critical for effective climate and hydrological services and early warnings. Yet hydrological monitoring capacity is on the decline. Many National Meteorological and Hydrological Services (NMHSs) operate with constrained financial and human resources, which can impact the quality of hydrological monitoring and related services. This challenge is often linked to limited awareness of and visibility of the critical value of hydrological monitoring data, the information derived from this data, and the services provided using this information. Join our webinar hosted by the WMO HydroHub to explore the socioeconomic benefits of investing in hydrological monitoring. Learn about methodologies, data, practical tools, and much more. Learn how to demonstrate return on investment and influence decision-makers. 📅 04 March 2026  📍Online  👉 Register here: https://lnkd.in/eFZWQRJ4

Important read here from our friends at Intergovernmental Oceanographic Commission (IOC) of UNESCO. Our oceans absorb around 25% of human-produced carbon dioxide, helping to slow global warming. A new scientific assessment, warns that this vital climate service is changing and that major knowledge gaps still limit our ability to predict how the ocean carbon sink will evolve. Closing the carbon-knowledge gap is essential for stronger, science-based climate action. Read the full report: https://lnkd.in/ehtrE7dq Photo by Frederic Christian

Early warnings in action. As a major winter storm affects the US and Canada, forecasts and alerts are supporting emergency response on the ground. Please follow local guidance and stay safe. #EarlyWarningsForAll Image: CIRA/NOAA

Call for Abstracts: The 8th WMO Symposium on Data Assimilation Are you interested in next-generation prediction, data-driven modelling, and the integration of machine learning (ML) with physical science? The 8th WMO Symposium on Data Assimilation, jointly organised with the 12th International Symposium on Data Assimilation, brings together researchers, operational experts, and innovators to explore how the DA landscape is being transformed by recent advances in observation, computation, and machine learning. We invite you to submit abstracts on emerging data assimilation methods, advances in machine learning and computation, and new ways to bridge models with real-world observations to improve prediction and decision-making. 📅 31 August 2026 – 04 September 2026 📍 Nanjing, China ⏳ Abstract Submission Deadline: 28 February 2026 👉 Learn more: https://lnkd.in/dXDCDmJW #WMO #DataAssimilation #Prediction #ScientificComputing #Forecasting #MLforScience #InterdisciplinaryScience

Since 14 January, France received 37 consecutive days of rainfall - a record since the start of measurements in 1959, according to METEO FRANCE. This satellite imagery shows the extent of massive flooding. The economic disruption is immense, but forecasts and early warnings - including many top-level Red Alerts - limited casualties. That's why the top priority of the World Meteorological Organization is #EarlyWarningsForAll. https://lnkd.in/eettgEuZ

🌦️ Innovating at the intersection of weather, people, and policy. The Weather and Society Conference 2026, under the WMO’s World Weather Research Programme (WWRP) will take place online from 23–26 February 2026, under the theme: 👉 Whole-of-Society Approaches for Weather-Ready Communities This event brings together researchers, practitioners, and decision-makers working at the intersection of meteorology, climate services, and social impact. It’s a space to share ideas, tools, and experiences that make weather and climate information more inclusive, actionable, and effective, especially for the most vulnerable. 💡 Why join? 🟦 Explore transdisciplinary, inclusive, and innovative approaches to weather and climate resilience 🟦 Connect with a diverse, global network of experts and practitioners 🟦 Be part of the conversation shaping equitable early warning systems and weather-ready societies. 🌍 Conference dates: 23–26 February 2026 (Online) 🔗 More details and registration: weatherandsociety.com Let’s continue building bridges between science, policy, and communities — and make weather information work for everyone. #EarlyWarningsForAll #ClimateAction
