On Friday, the third anniversary of climate campaigner Greta Thunberg’s lone protest outside the Swedish Parliament, a global report revealed the scale of risks posed by the climate emergency for the world’s children.

The UN’s agency for children’s rights, UNICEF, introduced the first-ever Children’s Climate Risk Index, which shows that nearly half of the world’s children are at “extremely high risk” for being faced with dangerous effects of the planetary crisis.

“The climate crisis is a child rights crisis,” said UNICEF.

About one billion children live in dozens of developing countries that are facing at least three to four climate impacts, including drought, food shortages, extreme heat and disease, the report, launched in collaboration with Fridays for Future, found.

“For the first time, we have a complete picture of where and how children are vulnerable to climate change, and that picture is almost unimaginably dire,” said Henrietta Fore, executive director of UNICEF, in a statement.

Some of the highest-risk countries include India, Nigeria and the Central African Republic — countries which are among the least responsible for rampant fossil fuel extraction and greenhouse gas emissions contributing to the climate crisis.

“The top 10 countries that are at extremely high risk are only responsible for 0.5% of global emissions,” Nick Rees, lead author of the report, told The Guardian.

UNICEF used high-resolution maps of climate impacts as well as maps showing children’s vulnerability to poverty, lack of access to clean water and other factors that make young people less able to survive climate-related catastrophes like extreme weather events.

While nearly half of the world’s children are at extreme risk for experiencing multiple effects of the climate crisis firsthand, nearly every child on Earth was found to be at risk for at least one impact, including heat waves and air pollution.

“Virtually no child’s life will be unaffected,” Fore said.

According to the report, 820 million children — more than one-third — are at risk for experiencing extreme heatwaves like the deadly ones that have affected the U.S.’ Pacific Northwest, Canada and Western Europe this year. One in seven children are at risk for facing flooding rivers, and two billion are currently highly exposed to air pollution.
