Overview
- The VUB-led analysis published in Science Advances reported that up to 560 million children aged 0–9—about 43% of that age group—are living through at least one additional month of humid-heat exposure per year due to human-caused warming.
- The study, released Wednesday, Aug. 26, finds children face far higher exposure than other age groups, with their burden nearly triple that of people aged 60–69 in some measures.
- Exposure is concentrated in poorer tropical regions where young populations and limited access to cooling raise risk, with the largest counts in South Asia, Southeast Asia and West Africa.
- Researchers used population data, climate models and attribution methods to isolate human-driven change and project that affected children would rise to about 620 million at 1.5°C warming and about 650 million at 2°C warming.
- Authors warn of immediate health threats such as heatstroke and dehydration, and call for rapid emissions cuts, a big increase in climate finance to developing countries, and targeted adaptation like heat-action plans, cooling access and stronger public-health systems.
