Virtually all children on Earth will face more frequent heatwaves by 2050

New Unicef report finds that in even best-case scenario 2 billion children will face four to five dangerous heat events annually

The climate crisis is also a children's rights crisis: one in four children globally are already affected by the climate emergency and by 2050 virtually every child in every region will face more frequent heatwaves, according to a new Unicef report.

For hundreds of millions of children, heatwaves will also last longer and be more extreme, increasing the threat of death, disease, hunger and forced migration.
