The briefing addresses the misconception that Europe’s recent heatwaves are caused by declining air pollution. It clarifies that while air pollution has complex effects on climate, the primary driver of increased heatwave frequency and intensity in Europe is global warming due to greenhouse gas emissions. Declines in certain pollutants like aerosols can have localized climate effects, but these are minor compared to the overarching impact of rising greenhouse gases. Scientific evidence shows that human-induced climate change is amplifying heat extremes by trapping more heat in the atmosphere, leading to longer and more severe heatwaves. Thus, attributing Europe’s heatwaves mainly to reduced air pollution oversimplifies and misrepresents the science. The briefing emphasizes the importance of addressing greenhouse gas emissions to mitigate future heatwaves rather than focusing on pollution reduction as a cause.
