Almost all of the world's children are exposed to at least one climate hazard, with as many as 1.8 billion put in danger ​by droughts and 1.2 billion by extreme heat, the United ‌Nations Children's Fund (UNICEF) said in a report on Tuesday.

UNICEF said children were "disproportionately affected" by a range of intensifying climate-related risks and governments urgently needed to invest in infrastructure, adaptation and ​disaster management capabilities to reduce their exposure.

Here are some of the ​details of UNICEF's Children's Climate Risk Report.

• The report looked at a broad range of climate hazards, as well as the impacts of air pollution and the risks of vector-borne diseases such as malaria. It also factored in data on access to water, healthcare, and social services across the world.
• As many as 1.1 billion children globally were exposed to at least three overlapping climate risks, the report ​said, warning of a "dangerous cascade of multiple, overlapping hazards" that could overwhelm governments ​and social services.
• "It's not just the exposure to the single hazards like floods or droughts ‌or ⁠heat waves and extreme heat that children face, but it is the exposure to multiple hazards," said Rohini Sampoornam Swaminathan, UNICEF statistics manager and one of the authors of the report.
• As many as 662 million children were at ​risk from tropical storms, ​337 million from ⁠riverine floods and 33 million from coastal floods, with 1 billion children also exposed to malaria, mostly in Africa.
• In 2024, 242 million children in 85 countries had their schooling disrupted by climate hazards.
• UNICEF identified Somalia, Madagascar, Myanmar, Cambodia and Pakistan as the most vulnerable countries.
• The highest numbers of drought-exposed children live in agriculture-dependent economies like Bangladesh, Indonesia, ⁠Nigeria, Pakistan ​and Tanzania.
• Children in landlocked nations were also ​facing "disproportionate" risks of drought, desertification, heat stress and flash floods, with water stress set to intensify in ​countries like Botswana and Burkina Faso.
