Climate Change Service: Nearly 40 Percent of Humanity Exposed to Extreme Ozone Levels

TVS News AI, editorially supervised, presents Climate Change Service: Nearly 40 Percent of Humanity Exposed to Extreme Ozone Levels.

When the air sits still and the heat bears down, you can literally taste it – and still breathe it in. A new analysis from a climate change service now shows how serious the situation really is in 2026: nearly 40 percent of the world's population is exposed to extreme ozone levels. Heat waves, fires, and Saharan dust have massively worsened global air quality this year.

What Do the Numbers Say?

According to the analysis, around 40 percent of people on Earth are exposed to ozone levels considered extreme – levels that can become truly dangerous for the respiratory system, heart, and circulation. Particularly impacted: densely populated regions and the warm months, when ground-level ozone forms especially intensely under solar radiation.

Why 2026 Stands Out

According to the available reports, multiple stressors are coming together this year: prolonged heat waves, large-scale fires, and Saharan dust carried across thousands of kilometers. This mix intensifies ozone formation in the atmosphere – the result is levels that, according to the analysis, affect nearly half of humanity.

What Does This Mean in Concrete Terms?

The analysis was picked up by Stern Panorama and Handelsblatt, with Die Zeit also reporting on it. The available excerpts do not name concrete regional recommendations for action – for example, for particularly polluted days or protective measures. What is clear, however: where heat, dust, and smoke come together, the burden on the respiratory system rises noticeably.
