Almost every child on Earth will suffer from heat waves by 2050
Hot weather has become a health risk for many nations, but new data shows that almost every child on Earth will be affected by heat waves by 2050, the UN Children's Fund (UNICEF) warned on Tuesday.
According to the UN agency, at least half a billion youngsters are already exposed to a high number of heat waves due to climate change.
By the middle of this century, it estimates that more than 2 billion children will be exposed to "more frequent, longer lasting, and more severe" heat waves.
"The climate crisis is a child rights crisis - and it is already taking a devastating toll on children's lives and futures," warned UNICEF Executive Director Catherine Russell.
Wildfires and heat waves in 2022 that have swept through India, Europe and North America were "yet another sobering example of the impact of climate change on children," she said.
New data published in the agency's report, The Coldest Year of the Rest of Their Lives, underscores that young children face greater risks than adults when faced with extreme heat events.
This is because they are less able to regulate their body temperature compared to adults. The more heat waves children are exposed to, the greater the chance of health problems including chronic respiratory conditions, asthma, and cardiovascular diseases.
"The world urgently needs to invest in building their resilience - and in adapting all the systems children rely on to meet the challenges of a rapidly changing climate," UNICEF maintained.
This is regardless of whether average global temperatures rise by 1.7 C above preindustrial levels if greenhouse gas emissions are low, or whether they rise by 2.4 C, if emissions are high.
Children in northern regions will face the most dramatic increases in high heat wave severity, while by 2050, nearly half of all children in Africa and Asia will face sustained exposure to extreme high temperatures over 35 C, UNICEF's data showed.
"This will have a devastating impact on children," said Vanessa Nakate, climate activist and UNICEF goodwill ambassador.
