Systematic attribution of heatwaves to the emissions of carbon majors.

ABSTRACT: Extreme event attribution assesses how climate change affected climate extremes, but typically focuses on single events^1-4. Furthermore, these attributions rarely quantify the extent to which anthropogenic actors have contributed to these events^5,6. Here we show that 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. This work relies on the expansion of a well-established event-based framework¹. Owing to global warming since 1850-1900, the median of the heatwaves during 2000-2009 became about 20 times more likely, and about 200 times more likely during 2010-2019. Overall, one-quarter of these events were virtua
