There were two “systems” that warned people about the impending danger that day: one built by the state relying on sensors and SMS messages, the other relying on community-based ties. Only the second worked reliably.

Machine-learning techniques could help provide more warning. By detecting subtle changes in the continuous vibrations around a volcano, they can potentially identify signs of an impending eruption hours beforehand.

A major climate adaptation programme is helping Egypt strengthen coastal resilience in the Nile Delta through nature-based coastal protection, climate-informed planning, coastal monitoring systems and integrated coastal zone management.

Most wildfires started by humans are still being called "wild", placing the fire outside human society. It implies there was no spark – and certainly no humans, and fails to widen the cause to include climate change, calling for new naming conventions.

Journalists, editors, disaster management authorities and regional partners gathered in N'Djamena from 27–29 July for a regional workshop aimed at strengthening climate reporting and media resilience across one of Africa's most vulnerable regions.

Wildfire misinformation spreads fastest in the hours right after a fire breaks out — checking a claim against a credible source before sharing it is the simplest way to slow it down.

Five South American countries are joining forces under a new regional forecasting programme to improve severe weather warnings across the La Plata Basin.

Forest fires will continue, meaning we need ongoing investment in prevention, land management and firefighting resources. But we also need to pay more attention to human behaviour.

This briefing warns that climate disinformation is spreading through European media and online platforms, undermining public trust, distorting debate on climate action and highlighting the need for stronger policy and regulatory responses.

UNICEF activated U-Report as a tool for mass communication to raise awareness and share life-saving information with young people.

As people across the UK feel the effects of what could be one of the longest-lasting heatwaves since 1976, communities around the world are also suffering from periods of extreme heat.

Dr Michael J Dillon and Professor Laura Bowater emphasise the significance of gamification in global health education amidst increasingly complex challenges

What would happen if a Category 5 tropical cyclone formed in the Mozambique Channel?

Adaptation is not a substitute for mitigation. Cutting emissions remains indispensable to preventing the worst outcomes of climate change. Even if we succeed in limiting warming to 1.5°C, we will still face more floods, heatwaves, and ecosystem losses.

The farmer’s phone had vibrated just an hour earlier – a community alert of heavy rainfall expected within 48 hours. These messages now arrive regularly.

The inland extent of watches and warnings will now be included, and an experimental cone will capture more areas at risk.

Help shape a new pilot project by selecting priority hazards and recommending experts for the Technical Working Group. The survey takes 5 to 7 minutes and all responses are confidential.

UNDRR & ARISE Japan joint symposium 2026 "Strengthening disaster risk reduction by advancing investment in resilience and translating science into Practical Action” as held in Tokyo with the presence of Mr. Kishore, Head of UNDRR, on 10 March 2026.

Extreme weather is one of the most harmful impacts of climate change, posing a risk to human health and well-being worldwide. However, the types and impacts of extreme weather vary widely across countries.

Digital technologies have revolutionized how we live, connect, and work, yet our growing reliance on these systems has created risks that often go unnoticed.

In an age of rapidly evolving digital media, helping young people to understand climate change requires more than just teaching the science. It is also about equipping them with the skills to navigate the information they encounter every day.

As record-breaking heat intensifies, Japan is pioneering a bold experiment in climate communication—using language, lived experience, and public participation to transform awareness of extreme weather into meaningful action

2025 marked a year of exceptional growth for the Stop Disasters game.

Frightening headlines predicting a Super El Niño or even a Godzilla El Niño amp up anxiety levels for farmers and residents of bushfire-prone regions.

This paper is about how AI language limitations can hinder effective climate disaster response by misinterpreting local expressions and urgency in affected communities

In 2025, secondary perils – among them wildfires, severe convective storms and floods – accounted for a record 92% of total global natural catastrophe insured losses of USD 107 billion.

The article argues that the 1985 eruption of the Nevado del Ruiz volcano, which killed more than 23,000 people largely due to poor preparedness and miscommunication, became a turning point that highlighted the role of vulnerability in disasters.

For the first time at the UN level, governments are explicitly committing to protect science-based climate information, support independent journalism, improve transparency, and counter disinformation that undermines public understanding.

UR26 invites practitioners, researchers, innovators, and policymakers to share ideas, tools, and experiences shaping the future of disaster risk management.

Climate change is making heat waves more frequent and severe, posing an increasing risk to human health. What is the best way for the news media and others to communicate these important facts about extreme heat?

A new report argues that English-only climate science and disaster alerts are excluding most of the world, and putting Indigenous communities at greater risk.

The article argues that managing the multi-risk environment of Campi Flegrei system requires rethinking how science, governance, and communication operate under deep uncertainty.

As dangerous extreme weather events increasingly affect communities across the nation, there’s an urgent need to share more timely, accessible, and actionable lifesaving information with all people—especially those who may experience added barriers.

What mattered was participatory learning over time: people being invited into respectful conversations, treated as capable decision-makers, and supported to work through risk in ways that made sense within their own lives.

In recent years, India has experienced frequent and intense heat waves alongside some of the highest levels of air pollution in the world. To understand how different groups of people view these hazards 10,751 adults were surveyed nationwide.

For psychological scientists, the task ahead is to understand what makes risk communication effective and how to motivate communities to take protective action.

In Australia, the only severe weather events that receive formal names are tropical cyclones. Could there be benefits to giving a name to all of our extreme weather?

On 15 December 2025, Tajikistan National Pillar Leads convened a coordination meeting with the relevant state agencies to review the implementation of the National Roadmap on Enhancing Early Warning System in the country.

Heat risk is crosscutting; therefore, no single sector or actor can tackle the challenge alone. The lessons below show what has been discovered about extreme heat and what it will take to respond in a world that will not cool down.

Sea level rise, local subsidence, canal siltation, ill-planned reclamation, and overstressed drainage systems together lengthen high tides, allowing slack water to linger for hours. Experts call it high-tide flooding or tidal flooding.

It’s time to redefine the term so it more clearly conveys meaningful risks to coastal communities and prompts them to act when needed.

The United Nations Office for Disaster Risk Reduction invites your feedback on how the development community engages with its disaster risk reduction tools and information resources.
