A recent report by the United Nations reveals that nearly half a billion children worldwide are now experiencing twice as many days of extreme heat compared to previous generations. This alarming trend is directly linked to the escalating impact of climate change, with the UN warning of severe and potentially deadly consequences for young children.
According to UNICEF, the UN’s children’s agency, around 466 million children, or one in five globally, reside in regions that have seen a significant increase in the number of extremely hot days each year compared to 60 years ago. These areas are now experiencing at least double the number of days where temperatures reach 95 degrees Fahrenheit (35 degrees Celsius) or higher.
Lily Caprani, UNICEF’s advocacy chief, emphasized the heightened vulnerability of young children to extreme heat, explaining that their bodies are less equipped to handle high temperatures than adults. She also highlighted the dangers posed to pregnant women and the broader implications for public health.
The report notes that extreme heat can lead to severe health issues for children, including heat stress, malnutrition, and increased susceptibility to diseases such as malaria and dengue, which thrive in warmer climates. Additionally, excessive heat can adversely affect neurodevelopment and mental health, further exacerbating the challenges faced by children in these regions.
UNICEF’s analysis shows that children in West and Central Africa are among the most affected, with 123 million children—approximately 39% of the region’s youth—experiencing extreme heat for a third of the year. In countries like Mali, where access to air conditioning is limited, children are exposed to more than 200 days of temperatures exceeding 95 degrees annually.
In Latin America, 48 million children are facing double the number of extremely hot days compared to 60 years ago. The global trend is concerning, as children are particularly susceptible to the effects of heat stress, which can be life-threatening.
In addition to health risks, extreme heat is also disrupting education. In 2024 alone, at least 80 million children have missed school due to high temperatures, with many schools forced to close or struggle to maintain a conducive learning environment.
UNICEF is advocating for increased education for parents on recognizing the signs of heat stroke, improved training for medical personnel, and investment in cooling infrastructure in schools. However, the organization stresses that addressing the root cause of the problem—climate change—is crucial.
UNICEF’s executive director, Catherine Russell, urged governments to consider the long-term impacts of their climate policies on future generations, as they draft their national climate action plans. She emphasized the need for ambitious and informed action to ensure that today’s children do not inherit an increasingly inhospitable world.
