More than one billion children — roughly half the world's child population — are now exposed to at least three simultaneous climate hazards, including heatwaves, floods, droughts and storms, according to a new UNICEF report. The agency highlighted the Sahel region of Africa and countries such as Bangladesh, Myanmar and Pakistan as among the worst affected, while noting that even wealthier nations are not spared, with over six million children in Italy regularly experiencing extreme heat and drought. UNICEF is urging governments and businesses to cut emissions and invest in climate-resilient infrastructure, health, and education systems, warning that the compounding effects of climate change are increasingly disrupting children's safety, schooling, and long-term survival.
