More than 1.5 million students in France experienced disruptions to their education in 2025 due to climate-related events, according to the United Nations Children's Fund (Unicef). In July 2025, extreme heatwaves forced the closure of over 2,200 primary schools, impacting approximately 505,000 students. These closures were part of a broader trend of climate-related disruptions that affected the school year in various regions of France, including the Bouches-du-Rhône and Var departments. In overseas territories, the impact was particularly severe. In Mayotte, a cyclone named Chido and a subsequent storm, Dikeledi, in January 2025 led to the postponement of students returning to school, affecting over 117,000 children. Meanwhile, in Reunion, cyclone Garance disrupted schooling for more than 217,000 students. Globally, 171 million students—roughly one in ten from preschool through higher education—had their schooling interrupted by climate-related events in 2025. These disruptions underscore the increasing vulnerability of education systems to climate risks, particularly in France. Unicef highlights the urgent need for better planning and preparedness to ensure that schooling can continue uninterrupted despite such challenges. The organization emphasizes that the impact of these events on learning conditions is a critical concern for policymakers and educators alike. In Mayotte, the effects of cyclone Chido, which struck nearly two years ago, are still being felt. Damaged school infrastructure continues to hinder children's access to education, demonstrating the long-term consequences of climate disasters. As the year 2026 begins, with repeated heatwaves already affecting the spring months, France is bracing for even more school disruptions. This ongoing pattern of climate-induced closures raises concerns about the sustainability of the education system in the face of a changing climate. Unicef urges French authorities to improve data collection on climate-related school interruptions. Better data, the organization argues, will help in developing more effective strategies to adapt schools to future climate risks. This includes not only infrastructure improvements but also policies that ensure continuity of learning during and after climate events. As climate change continues to shape the environment, the need for proactive measures in the education sector becomes ever more pressing.
