Extreme heat exposure on the rise for millions of kids – UN

UNITED NATIONS — Nearly half a billion children are facing twice as many days of extreme heat each year — or more — than their grandparents did, the UN said Tuesday, warning of deadly consequences.

As climate change continues to push up temperatures globally, one in five children — some 466 million kids — live in areas that are registering «at least double the number of extremely hot days every year» compared to 60 years ago, the UN children's agency Unicef said.

«The bodies of young children are not like little adults; they have much more vulnerability to extreme heat,» Unicef advocacy chief Lily Caprani told Agence France-Presse, also warning of dangers for pregnant women.

Additionally, children lose out on education when schools are forced to close due to high temperatures — which has affected at least 80 million children in 2024 so far.

Unicef used days reaching 95 degrees Fahrenheit (35 degrees Celsius) as its benchmark, comparing average temperatures in the 2020–2024 period to the 1960s.

Such hot days — as well as the means to cope with high temperatures, such as air conditioning — affect the entire world, it noted.

Children in West and Central Africa are the most exposed, with 123 million children — 39 percent of the kids in the region — facing a third of each year with 95-degree days or higher.

At the higher end, in Mali, for example — where air conditioning is out of reach for millions and blackouts can leave fans idled — more than 200 days a year can reach 95 degrees or higher.

In Latin America, meanwhile, 48 million children are facing double the number of 95-degree or higher days than 60 years ago.

Worldwide, the «trajectory is getting worse and worse for these children,» Caprani said.

Children «are fragile, and they breathe very quickly. They can't even sweat like an adult does. They are much more vulnerable to heat stress, and it can be literally deadly,» she added.

High temperatures can contribute to child malnutrition and leave kids more vulnerable to disease, especially
