Nearly half of world's children face at least three climate hazards, UNICEF warns
More than one billion children—nearly half of the world’s 2.4 billion under-18 population—are now exposed to at least three overlapping climate hazards, the United Nations Children’s Fund warned on Tuesday, as heatwaves, floods, storms and droughts intensify across every continent. The findings, released by UNICEF on 16 June 2026, show that almost every child on Earth faces at least one climate risk, two billion face at least two, and 364 million confront four or more simultaneous threats to their health, education and survival .
The report catalogues the most common combinations: drought, extreme heat and heatwaves afflict the largest number of children, while floods and storms compound risks in densely populated river deltas and coastal zones. In Chad, one of the world’s poorest countries, UNICEF estimates that more than 95 per cent of children are threatened by the same trio of drought, extreme heat and heatwaves—the most frequently occurring cluster globally .
Even high-income nations are not spared. The data indicate that children in Europe and North America are increasingly exposed to prolonged heatwaves and severe storms, disrupting schooling and increasing heat-related illness. “The climate crisis is a child-rights crisis,” said UNICEF Executive Director Catherine Russell. “When a child faces multiple climate shocks at once, the cumulative impact on their nutrition, learning and safety can be catastrophic.”
The report arrives amid a surge in extreme weather events. In South Asia, monsoon flooding has displaced millions of families during the 2026 monsoon season, while sub-Saharan Africa endures a fourth consecutive year of failed rains. UNICEF’s analysis draws on the latest climate models and child-population data to map exposure at subnational level, revealing that children in the Sahel, the Horn of Africa and parts of Southeast Asia face the highest combined burdens.
UNICEF is calling for accelerated adaptation measures, including climate-resilient schools, early-warning systems and social protection programmes that prioritise pregnant women and young children. “We have the tools to protect the next generation,” Russell said. “What we urgently need is the political will and the financing to deploy them at scale.” The agency estimates that an additional $1 trillion in annual climate finance is required to shield children from the most severe impacts by 2030.
