The youngest generation is carrying a climate burden it did not create.

Human-induced climate change is exposing as many as 560 million children aged nine or younger to at least one additional month of dangerous heat every year, according to research from Vrije Universiteit Brussel. The study, published in Science Advances, found that children face a greater increase in heat-stress exposure than any other age group. The figure is nearly three times the estimated 190 million adults aged 60 to 69 experiencing the same additional threat.
Children are particularly vulnerable because their bodies regulate temperature less efficiently. They sweat less relative to their body weight, have higher metabolic rates and can heat up more rapidly during extreme conditions. Dangerous heat can cause dehydration and heatstroke, aggravate existing illnesses and increase the risk of kidney or respiratory damage.
Exposure is concentrated in South Asia, Southeast Asia and West Africa, where humid heat is increasing rapidly and populations are comparatively young. Poverty, inadequate housing, limited electricity and restricted access to cooling or healthcare further reduce families’ ability to protect children. Heat also creates indirect risks by disrupting food and water supplies, increasing mosquito-borne diseases, affecting infant feeding and contributing to pregnancy and birth complications.
The researchers distinguished current estimates from future projections. At 1.5°C of global warming, approximately 620 million children could experience at least one additional month of heat stress annually, while 390 million could endure at least five months of dangerous conditions in total. If warming reaches 2°C, those estimates rise to 650 million and 420 million children respectively.
Reducing greenhouse-gas emissions remains essential, but current exposure also requires immediate adaptation. Governments can introduce heat-warning systems designed for children, improve ventilation and shade in schools, expand access to drinking water and adjust outdoor activities during dangerous temperatures. Health services must also recognize heat stress earlier, particularly in newborns and children with chronic conditions.
The findings reveal that climate change is not only an environmental forecast but an existing public-health inequality. Children in regions least responsible for historic emissions often have the fewest resources to escape the heat. Protecting them will require climate policy to measure success not only through temperature targets, but through access to safe housing, healthcare, water and resilient public infrastructure.
