The briefing addresses misconceptions linking Europe’s recent heatwaves directly to declining air pollution levels. It clarifies that while air pollution, particularly aerosols, can influence local climate by affecting sunlight absorption and cloud formation, the current intense heatwaves are primarily driven by global climate change due to greenhouse gas emissions. Scientific studies show that long-term warming trends, rather than short-term fluctuations in air pollution, are the main cause of increased frequency and severity of heatwaves across Europe. Although reductions in air pollution may have minor regional effects on temperature, these do not ‘cause’ heatwaves. Instead, the persistent rise in global temperatures from carbon dioxide and other greenhouse gases is the dominant factor. The briefing emphasizes the importance of addressing climate change through emission reductions rather than misattributing heatwaves to air pollution declines. This distinction helps ensure accurate public understanding and effective policy responses to extreme weather events linked to climate change.
