Heatwaves, Wildfires Expose a Third of World to Extreme Ozone Pollution
- On Wednesday, a European Union report from the Copernicus Climate Atmosphere Monitoring Service revealed that record heatwaves and wildfires exposed one-third of the global population to extremely high levels of ozone pollution this year.
- Ground-Level ozone forms when heat and sunlight react with airborne emissions from wildfires, vehicles, and industry; climate change fuels conditions that favor its formation, making the pollutant difficult to tackle despite past progress.
- Asia faces the highest exposure, with 53 percent of its population breathing "extremely poor" air, while Oceania remains a bright spot where 66 percent of the population enjoyed "good" ozone levels.
- CAMS director Laurence Rouil stated, "Air pollution does not stop at borders," noting it crosses continents and oceans; the European Environment Agency linked ozone exposure to 60,000 premature deaths annually in Europe.
- The warming El Nino weather pattern, which began in June and is expected to peak later this year, could drive further wildfires in south-east Asia, potentially exacerbating ozone pollution levels.

The record heat waves and forest fires worsened the situation in 2026, according to the European Copernicus Service. Asia appears to be the most affected region with 53% of its affected populationThe heat waves and forest fires, combined with human emissions, have exposed more than a third (34%) of the world's population this year to extremely high levels of ozone pollution, according to a report by the European Copernicus Service.

About half of the European population has already breathed air this year with ozone levels ranging from ‘poor’ to ‘extremely poor’, the European climate service Copernicus shows in a report. According to the researchers, nearly four out of ten people worldwide have already been exposed to ‘dangerously high levels’ of this pollution this year.
Berlin, 30 Sep (EFE).- A new global analysis by Copernicus shows how air pollution crossed borders and continent last year, exposing 40% of the world's population to harmful levels of ozone, warned on Wednesday the atmospheric and climate monitoring component of the European space program. tropospheric ozone arises [...] Entry 40% of the world's population suffered harmful levels of ozone in 2026, warns Copernicus was first published in HolaNews.
