Here we show how GHG emissions from consumption and investments attributable to the wealthiest population groups have disproportionately influenced present-day climate change. We link emissions inequality over the period 1990–2020 to regional climate extremes using an emulator-based framework. We find that two-thirds (one-fifth) of warming is attributable to the wealthiest 10% (1%), meaning that individual contributions are 6.5 (20) times the average per capita contribution. For extreme events, the top 10% (1%) contributed 7 (26) times the average to increases in monthly 1-in-100-year heat extremes globally and 6 (17) times more to Amazon droughts. Emissions from the wealthiest 10% in the United States and China led to a two- to threefold increase in heat extremes across vulnerable regions. Quantifying the link between wealth disparities and climate impacts can assist in the discourse on climate equity and justice. 2025-05-07 published Nature Publishing Group doi:10.1038/s41558-025-02325-x 3810 3377 3234 3176 3686 public Nature Climate Change 15 627-633 TRUE 1758-678X https://doi.org/10.5281/zenodo.14860538 data https://github.com/sarasita/attribution.git code https://doi.org/10.5281/zenodo.15011461 code Paris Agreement Overshooting – Reversibility, Climate Impacts and Adaptation Needs (PROVIDE, H2020 101003687) Socioeconomic Pathways, Adaptation and Resilience to Changing CLimate in Europe (SPARCCLE, HE 101081369) Earth system models for the future (ESM2025, H2020 101003536) Sustainability Performances, Evidence and Scenarios (SPES, HE 101094551) Enabling and Leveraging Climate Action Towards Netzero Emissions (ELEVATE, HE 101056873) Climate Change and Human (Im)Mobility: The Role of Compound and Cascading Risks (2C-RISK, HE 101162653) yes info:eu-repo/grantAgreement/EC/HE/101081369/EU//SPARCCLE; info:eu-repo/grantAgreement/EC/HE/101003687/EU//PROVIDE; info:eu-repo/grantAgreement/EC/HE/101056873/EU//ELEVATE; info:eu-repo/grantAgreement/EC/HE/101162653/EU//2C-RISK info:eu-repo/semantics/article info:eu-repo/semantics/openAccess
