WMO coordination of weather, climate and water services is central to global safety, security and development, but sustainable funding remains a challenge. In 2025, we call for both public and private sector engagement.

Extreme heat grips many parts of Europe As a result of human-induced climate change, extreme heat is becoming more frequent and intense. Warnings from National Meteorological and Hydrological Services and coordinated heat-health action plan...

In western and south-western Europe both minimum (representative of nighttime conditions) and maximum temperatures (usually occurring during the afternoon) broke monthly station records for June in some locations. This is the #StateOfClimate.

Despite growing global attention and funding, many early warning systems still miss the mark. Too often, they’re built for people, not with them—and that’s a problem.

A new policy brief explores why. www.early-action-reap.org/policy-brief...

The Global Early Warnings for All Multi-Stakeholder Forum kicks off today, bringing together experts, governments, and communities to accelerate action on ensuring everyone, everywhere has access to life-saving early warning systems.

9/ This mission only works if it works for everyone.
We are teaming up with governments and the private sector. Together, they’re building a future where no one is left behind.

“AI can make early warnings cheaper, faster, more accessible,” says Laura Paterson (
@wmo-global.bsky.social ).
“But we must close the data divide.”
This isn’t just about tech — it’s about justice.

7/ In Seychelles, AI is now helping predict tsunamis, algal blooms, & wildfires.

But as Xavier Estico puts it: “Our ambition is clear, but the challenges are real: limited funding, fragmented data, and a small population base."

6/ Do people trust warnings?
"Trust isn’t built at the point of impact. It starts with design." — Joshua DeVincenzo, @columbiauniversity.bsky.social

WMO & partners are shifting from just ‘data delivery’ ➡️ to decision support. Warnings must be human-centered.

5/ “We realized early on that the foundation for early warning systems isn’t just technology. It’s knowing where people live. " — Juan Lavista Ferres, @microsoft.com

Many regions had no up-to-date maps. Using satellite images + AI, they found the invisible.

4/ “Connectivity is not a technical afterthought. It’s the lifeline." — Seizo Onoe, @itu.int

"Without it, even the most advanced early warning systems are rendered useless.”

3/ “Disasters don’t wait.”

🇷🇼 Rwanda’s Robert Kayinamura:

"In Rwanda last year, floods and landslides claimed over 130 lives and displaced more than 16,000. These are not just numbers — they are families, they are futures.”

2/ Why this matters
As climate extremes intensify, early warnings are no longer a luxury — they’re lifesaving infrastructure.
🌪️ Floods
🔥 Wildfires
🌊 Tsunamis
AI + real-time data can give more people a heads up.

AI for Early Warnings: Experts unite with calls to build resilience and protect development gains | UN Office for Partnerships AI, equity, and partnerships take center stage in the global push for early warnings for all by 2027.

🧵 THREAD: Can AI help protect communities from climate extremes?

1/ Nearly half the world is still not covered by an early warning system.

📍At #STIForum, global leaders, tech innovators & UN say: It’s time to scale AI-powered early warnings for all. unpartnerships.un.org/news/2025/ai...

State of the Global Climate 2024

📊 While you're at it, check out our latest #StateOfClimate report: wmo.int/publication-...

📘 A new collaborative paper traces the origin of the Warming Stripes and explores how they now tell a more complete story of our planet's climate.

📰 Published in the Bulletin of the American Meteorological Society: journals.ametsoc.org/view/journal...

It reveals:

🔹 Warming in the troposphere
🔹 Warming in the upper ocean
🔹 Cooling in the stratosphere

These patterns highlight that climate change affects the entire Earth system — not just surface temperatures.

But did you know the stratosphere is cooling?

This counterintuitive trend becomes clearer when we extend the Warming Stripes concept across the entire climate system.

The Warming Stripes — a powerful visual of the #StateOfClimate — now stretch deeper into the ocean and higher into the stratosphere.

Selected tools will be featured in the Global Goods Guidebook for Climate and Health—a new resource showcasing adaptable technologies ready to be scaled and used around the world.

In partnership with PATH, Wellcome Trust, and The Rockefeller Foundation, the World Meteorological Organization and World Health Organization are calling for submissions of innovative, open-source solutions.

By making tools that connect climate, weather, and health data more accessible, we can better predict and respond to disease outbreaks, extreme heat, and other climate-related health system challenges.

If you’ve developed a software application, service, or content that uses climate and weather data to support health decision-making, we want to hear from you 👉 Submit by 30 April: digitalsquare.org/global-goods...
