More than 171 million students worldwide, about 1 in 10 from pre-primary to upper secondary age, had their schooling disrupted by climate hazards in 2025, according to a UNICEF analysis released on 10 September 2026. The report draws on data from 106 countries or territories and covers storms, floods, heatwaves, droughts and wildfires that led to suspended classes, damaged schools, remote learning, reduced attendance and greater dropout risk.

Storms were the most common cause, affecting 109 million students, UNICEF said. Floods affected at least 70 million and heatwaves about 50 million. Three-quarters of affected students live in low- and lower-middle-income countries. In Pakistan, severe monsoon floods in August delayed the return to school for over 28 million students, while a nationwide one-day class suspension during an April Khamsin storm in Egypt affected more than 28 million.

UNICEF said 40 countries experienced multiple rounds of disruption, citing Madagascar and Spain. It estimated that inaction could cost at least US$200 billion in lifetime earnings for students affected in 2025, and noted girls face higher dropout risk. The agency called for climate-resilient education systems, stronger school infrastructure, continued learning during emergencies and better climate and education data.
