Children Face Triple Climate Threats: UNICEF Report Highlights Global Exposure

UNICEF’s Children’s Climate Risk Report 2026 shows that 1.1 billion children—almost half of the world’s child population—are exposed to at least three overlapping climate hazards. The study matched the locations of roughly 2.4 billion children with the geographic spread of eight common climate threats, documenting a steep rise in multi-hazard exposure over the past two decades.

Nigeria, Pakistan and India have the largest absolute numbers of children facing three hazards. In Sub-Saharan Africa, especially the Sahel, the share of children at risk is highest; Chad reports over 95 % of its children exposed to three hazards. All children in 24 Small Island Developing States, from Haiti to Vanuatu, confront tropical storms, while Italy records more than 6 million children under prolonged heatwaves and drought.

• 2.3 billion children exposed to at least one hazard.

• 2 billion exposed to two hazards.

• 296 million children face the dominant trio of drought, extreme heat (>35 °C) and heatwaves (including 74 million in Nigeria, 34 million in Pakistan, 32 million in India).

• Air pollution reaches nearly every child; malaria threatens 1 billion children, especially in Africa.

Concurrent hazards intensify threats to health, nutrition, education and safety. Children’s faster temperature rise, higher water needs and rapid breathing increase vulnerability to heat stress and disease. Overlapping events strained health systems and disrupted schooling for an estimated 242 million children in 2024, while amplifying food insecurity, displacement and outbreaks of malaria and cholera.

UNICEF warns of growing climate threats facing children worldwide

Executive Director Catherine Russell warned that climate-related disasters are reshaping daily life for children worldwide and urged governments to embed child-focused resilience in national adaptation plans. Data Director Rohini Somanathan Swaminathan highlighted the compounded risk of simultaneous hazards, calling for urgent emission cuts, climate-resilient infrastructure and inclusive disaster-risk governance. UNICEF also stresses the need for safe schools, robust early-warning systems and child-centric social protection.

Report authors Tom Slaymaker and Tom Schleimecker note that the analysis covers only the eight most common hazards, omitting risks such as glacier melt, permafrost thaw or other region-specific threats. Consequently, some northern-hemisphere populations—particularly in Scandinavia—appear less exposed, though they may face climate-linked dangers not captured in the current framework.

UNICEF calls for rapid scaling of renewable energy, phasing out fossil fuels, and integrating child-critical services into climate-adaptation strategies. Priorities include climate-resilient schools and health facilities, multi-hazard early-warning tailored to children, and strengthened water, sanitation and social-protection systems.

• “Rohini Somanathan Swaminathan, UNICEF’s Director of Data, Analytics, Planning and Monitoring, said the threat extends beyond exposure to individual hazards such as floods, droughts or heat waves, encompassing simultaneous exposure to multiple climate risks that further increase community vulnerability.” — Rohini Somanathan Swaminathan, UNICEF Director of Data, Analytics, Planning and Monitoring
