Understanding Children's Climate Risks

More than a billion children are now facing at least three overlapping climate hazards — at great risk to their health, safety and well-being. Understanding who is affected most, and where, is an important step toward reducing these risks and protecting children's futures. UNICEF's latest climate report provides insights to inform practical solutions.

UNICEF report finds over a billion children in the world exposed to at least three overlapping climate hazards

While all 2.4 billion children in the world are now exposed to at least one climate hazard — be it floods, drought, storms or extreme heat — an estimated 1.1 billion children are now exposed to at least three, at great risk to their health, safety and future well-being.

This is the main takeaway of UNICEF's 2026 Children's Climate Risk Report, released on June 16, 2026.

The 2026 Children's Climate Risk Report builds on UNICEF's groundbreaking 2021 Children's Climate Risk Index. While the Index ranked countries according to children's overall climate risk, the new report provides a more detailed picture of where specific climate hazards are occurring, how intensely they affect children and where essential services are least able to withstand these shocks. 

Mapping where — and how intensely — climate change is putting children in real danger

The 2026 Children's Climate Risk Report marks an important milestone in understanding just how climate hazards and related impacts are affecting children — and how best to respond. Using updated data and improved models, the report pinpoints where climate hazards pose the greatest risks to children and where overstretched health, education and other essential services are least able to cope.

Without identifying who the most vulnerable children are, where they live and how they are affected, it’s nearly impossible to develop practical and effective solutions. And climate impacts are only expected to get worse in the coming decades.

Mapping the most common climate threats, from floods to droughts to extreme heat

The 2026 report covers eight most common climate threats: coastal floods, droughts, extreme heat, fires, heat waves, riverine floods, sand and dust storms and tropical storms. It also analyzes children’s exposure to air pollution and malaria, two risks that are highly sensitive to the effects of climate change and that add another layer of danger.

Globally, drought is the most widespread climate-related risk, threatening around 1.8 billion children. Frequent, longer or more severe heat waves threaten 1.5 billion children worldwide. Exposure to extreme heat is also widespread, threatening 1.2 billion children. Some 296 million children in the world live under threat of all three.

Children across sub-Saharan Africa and Asia most exposed to multiple climate risks

While the climate crisis is a global phenomenon, its effects aren’t felt equally, the UNICEF report makes clear. Children across sub-Saharan Africa and Asia are among the most exposed to multiple climate hazards at the highest intensity. 

In the Sahel region of Africa, one of the hardest hit by climate hazards, millions of children face the threat of heat and sand and dust storms. In Bangladesh, Myanmar and Pakistan, children are exposed to more climate hazards at once and at a higher intensity than anywhere else in the world. In small island states, from Haiti to Vanuatu, a single storm can overwhelm entire systems at once.

Often, children at greatest risk of climate impacts live in places where critical services are already weak or strained, making it that much harder for children and communities to cope and recover.

Floods, for example, often trigger outbreaks of diseases like cholera. If drought follows soon after, those same children, already weakened, are far more prone to malnutrition

Storms destroy health clinics, disrupting access to essential care. They force school closures, increasing risks of child labor and child marriage.

Each shock makes the next one more dangerous, pushing children closer to the edge.

A call for urgent, child-focused climate action

The report also points to practical solutions. With better data on where risks are greatest, governments can make smarter investments that strengthen the systems children rely on before disasters strike. 

While providing a much clearer picture of where children are most at risk from climate hazards — and where action is most urgently needed — the report also offers a flexible framework for governments and partners to perform their own risk assessments.

UNICEF's global call to climate action includes three major areas of focus:

  • cutting emissions and moving away from fossil fuels, while ensuring the transition is fair and grounded in the best available science
  • investing much more in the services children rely on, like health care, education, water and protection systems
  • empowering children and young people, by investing in climate education and making sure they have a real voice in decisions that affect their lives and their future

Alongside partners, UNICEF supports community efforts to build climate resilience, reduce disaster risks and include young people in decisions that affect their future well-being.

How UNICEF is already working to reduce disaster risks and build climate resilient systems to protect children

Some of the ongoing efforts to strengthen systems to withstand climate shocks include:

  • upgrading vaccine cold chain infrastructure through solar power and energy-efficient cooling systems to ensure reliable access to routine child immunization
  • installing solar-powered water systems and climate-resilient boreholes to ensure reliable access to safe water for communities, schools and health facilities during droughts and power outages 
  • retrofitting schools and health facilities with flood- and heat-resilient infrastructure to maintain essential services during extreme weather events
  • strengthening water and sanitation systems through rainwater harvesting, MBBR (moving bed biofilm reactor) wastewater treatment and other climate-resilient approaches to reduce water shortages and protect essential services

UNICEF staff person talks to students in a classroom in Sofala, Mozambique.
At Chissinguana Primary School in Mozambique's Buzi district, Sofala province, Baltazar Mite, a UNICEF Sofala infrastructure program manager, speaks with students about climate change. The classroom was one of many to be rehabilitated as part of a UNICEF-supported climate resilience program implemented in the wake of two back-to-back cyclones in 2019. To accelerate recovery and to improve access to safer schools for students affected by cyclones and floods, — while investing in infrastructure more resistant to future natural disasters — the Ministry of Education (MINEDH), in partnership with UNICEF, through funding from the Global Partnership for Education (GPE), completed rehabilitation and reconstruction of some 600 classrooms in Sofala, Manica, Nampula and Cabo Delgado provinces, taking a Building-Back-Better (BBB) approach. In Buzi District alone, 87 classrooms in 24 schools were reconstructed or rehabilitated, benefitting over 11,200 students. © UNICEF/UNI404994/Zuniga
