European UnionOnly 5% of humanity breathed good ozone this year.
Asia fared worst, with at least 53% of people breathing extremely poor air, Copernicus said.
Ozone forms when heat and sunlight react with wildfire, vehicle and industrial emissions, so heat waves add to it.
The analysis says El Niño, peaking later this year, could drive more Southeast Asian fires.
