A paper published in Nature in September suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪
Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.
