'Climate breakdown' alert as air quality dips during heatwaves: UN chief

"...The 2023 WMO Air Quality and Climate Bulletin – coming on the heels of the Secretary General’s statement – puts the spotlight firmly on the damage caused by heatwaves. It notes that high temperatures are not only a hazard by themselves, but they also trigger damaging pollution. Based on the 2022 data, the report shows how heatwaves fanned a dangerous drop in air quality last year..."
