In 2025, disasters involving natural hazards killed 16,607 people, affected 110.2 million and caused US$169.7 billion in economic losses, according to the latest EM-DAT report from CRED - Centre for Research on the Epidemiology of Disasters:
🌍 Asia accounted for 72.8% of disaster deaths, driven largely by earthquakes in Myanmar and Afghanistan
🌊 Storms affected 54 million people – well above the 2005–2024 annual average of 34.2 million
🔥 US wildfires generated US$53.9 billion in economic losses – the costliest single hazard of the year
🏜️ Drought affected 27.3 million people, with Syria (16.2 million) and Somalia (6.5 million) among the hardest hit
📊 Most 2025 indicators remain below the 20-year average – in part because heatwave and drought deaths are still being counted.

But these figures tell only part of the story. EM-DAT data reflects what gets reported: major events in data-rich contexts, direct and immediate impacts. Drought-related mortality, heat deaths, and losses in under-resourced settings remain systematically undercounted – and these gaps in global disaster datasets reflect gaps in protection from hazards. Populations absent from global datasets are often those facing the greatest risk.

Comprehensive, inclusive data is needed for effective disaster risk reduction.

Engineers know natural hazards are only part of the story. Poor design, inadequate materials, and gaps in stress testing all shape whether infrastructure holds or fails.

🏗️ Calling the outcome a "natural disaster" closes the file before the real questions get asked – what went wrong, and how design and maintenance can improve before the next hazard arrives.

Engineers already understand that there is no such thing as a natural disaster when it comes to infrastructure failure – only construction that wasn't built to withstand the hazards it faces.

🎒 Disaster risk doesn’t stop at the school gates.

In 2025, climate hazards disrupted the education of more than 171 million students. Around 1 in 10 globally.

Disruption came from multiple hazards:
🌪️ Storms affected 109 million students
🌊 Floods affected at least 70 million
🌡️ Heatwaves affected around 50 million

The disruption include closed or damaged schools, fewer hours of learning, lower attendance and, for some children, a greater risk of never returning to the classroom. Three-quarters of affected students lived in low- and lower-middle-income countries.

🏫 Education disruption is not inevitable. Climate-resilient schools, stronger data and preparedness, sustained financing, and equipping young people with resilience skills can help keep learning going when hazards strike.

A city's disaster plan is incomplete without its public health plan. 🏙️🏥

📚 This free e-learning course from UNDRR, World Health Organization (WHO) and United Nations Institute for Training and Research (UNITAR) equips local government officials and disaster management professionals to:
✅ Apply the Disaster Resilience Scorecard for Cities — including its Public Health System Resilience Addendum — to local risk planning
✅ Integrate public health considerations into disaster risk reduction and resilience strategies
✅ Use WHO's Health Emergency and Disaster Risk Management (Health EDRM) Framework to coordinate across sectors
✅ Strengthen local governance capacity for multi-hazard risk, from infectious disease outbreaks to climate-related events

For effective urban resilience, public health systems and disaster risk management must be planned together. Learn how ➡️ https://ow.ly/Qw3I50YBTej

KIKIKURU means 'risk is imminent' in Japanese – and is the name of the country's innovative 📢 early warning system for rain-related hazards. ☔

🏔️In Japan, two thirds of the land is mountainous or hilly, leaving small habitable areas vulnerable to landslides, inundations, and floods.

Of all the risk reduction and climate adaptation measures, early warning and early action stand out as proven and cost-effective methods to reduce deaths and damages caused by hazards.

📺Discover how this system in Japan provides real-time hazard updates.

🗞️ Responsible journalists must be allowed and encouraged to dig deeper than the headlines.

Disasters don’t come out of nowhere. We know what drives disaster risks, and what can be done to reduce them. Reporters must ask the tough questions:

❓Were there actionable early warnings?
❓Did poor planning fuel the damage?
❓Who suffered most – and why?
❓What were the hidden losses?
❓How can we build back better to reduce future risks?

Calling out neglect isn’t just brave – it’s essential. Governments and authorities have a duty to act to reduce disaster risks; and a free, empowered press must call them to account.

🌫️Uncertainty shapes every decision people make. Understanding how people perceive uncertainty can help strengthen disaster risk communication.

🌊 While flood risk messaging has grown more precise, less attention is paid to how people interpret uncertainty. Research from Germany's Universität Osnabrück and Weizenbaum Institute introduces the Uncertainty Lens Framework (ULF) to show why this matters.

Drawing on the 2021 floods in Germany, the study reveals how perceived uncertainty – rather than technical uncertainty alone – shapes:
🟢 Threat appraisal
🟢 Ownership and responsibility
🟢 Coping and response

Three common illusions of safety emerge: reliance on past experience, delegated responsibility, and faith in institutional preparedness. These are reinforced by cognitive heuristics – mental shortcuts – and by communication that downplays residual risk.

🔍 The research indicates that uncertainty should be integrated, not minimised. Purposefully setting anchors and availabilities can help people contextualise risk, strengthen agency, and support anticipatory action – especially alongside early warning systems.

Openly acknowledging uncertainty, across individuals, communities and institutions, helps to strengthen risk awareness and build resilience.

🐠Fish are shrinking. Maturing younger, dying faster, and losing the genetic variation that builds large bodies.

A new study in Science models the evolutionary impact of warming waters on global fisheries – and the outlook is bleak for fish fanciers:
🐟 Global fish yields could fall by 22% at 2°C of warming – worse than earlier projections, which didn't account for evolutionary change
📉 For Alaska po***ck alone, that's over 500,000 metric tons lost per year – more than 1.1 billion meals of high-quality protein, gone from a single species
🌊 Freshwater systems warm faster than oceans, meaning the steepest size reductions hit inland fisheries hardest
⚠️ As harvested fish shrink, they become prey rather than predators – potentially tipping entire ecosystems into configurations they cannot reverse

This is about much more than what's on the plate: billions of people depend on seafood as their primary protein source – and the demand is rising.

Fish can adapt to survive warming, but the people who depend on fisheries cannot adapt their way out of ecosystem collapse.

Effective climate policy could preserve roughly 18 million metric tons of yield annually. That's the catch worth protecting.

Climate and disaster risks are escalating, interconnected, and increasingly complex — demanding a shift from reactive response to proactive, risk-informed action. 🤝

The Global Synthesis Report on Comprehensive Risk Management (CRM) provides the first worldwide snapshot of how countries, regions, and institutions are aligning disaster risk reduction (DRR) and climate action for sustainable development.

Drawing on analysis of National Adaptation Plans (NAPs) and national DRR strategies, the report highlights promising trends, persistent gaps, and practical pathways for coherence across governance, financing, and implementation.

It shows how global frameworks – the Sendai Framework, the Paris Agreement, and the 2030 Agenda for Sustainable Development – are being translated into integrated, risk-informed policies and actions.

Recommendations:
✅ Strengthen governance for coherence and resilience
✅ Improve coordination and inclusiveness across levels
✅ Develop shared understanding of risk through integrated data
✅ Increase and align finance for DRR and climate action
✅ Establish holistic monitoring and evaluation systems
✅ Translate global frameworks into national and local implementation

These steps together tackle climate and disaster risk, charting a path towards a resilient future ➡️ https://ow.ly/Q4st50XplfU
