The live measurement per https://waqi.info at my home location is 5, the interactive map of the guardian says "8.5 to 10". Who to trust? Idk

Hooray!

This is the best summary I could come up with:

Europe is facing a “severe public health crisis”, with almost everyone across the continent living in areas with dangerous levels of air pollution, an investigation by the Guardian has found.

Analysis of data gathered using cutting-edge methodology – including detailed satellite images and measurements from more than 1,400 ground monitoring stations – reveals a dire picture of dirty air, with 98% of people living in areas with highly damaging fine particulate pollution that exceed World Health Organization guidelines.

The measurements refer to PM2.5 – tiny airborne particles mostly produced from the burning of fossil fuels, some of which can pass through the lungs and into the blood stream, affecting almost every organ in the body.

“This is a severe public health crisis,” said Roel Vermeulen, a professor of environmental epidemiology at Utrecht University who led the team of researchers across the continent that compiled the data.

“These deaths are preventable and the estimate does not include millions of cases of non-fatal diseases, years lived with disability, attributable hospitalisations, or health effects from other pollutants.”

Some towns and cities across Europe, including London and Milan, are making strides to tackle air pollution, from the introduction of ultra-low emissions zones to traffic reduction schemes and walking and cycling initiatives.

The original article contains 910 words, the summary contains 207 words. Saved 77%. I'm a bot and I'm open source!

Be nice to see if there’s an interactive map with companies that are producing pollution …
