US EditionWorld's wealthiest 10% have contributed to two-thirds of global warming since 1990, study finds
- Researchers reported in 2025 that the wealthiest 10% caused two-thirds of global warming and related extreme weather since 1990.
- The study links this impact to the consumption and investments of rich individuals, especially affecting vulnerable regions like the Amazon and Southeast Asia.
- Lead author Sarah Schöngart and co-author Carl-Friedrich Schleussner combined economic data with climate simulations to quantify these emissions and their effects.
- The wealthiest 1% were responsible for emissions linked to rare heatwaves at a rate 26 times the global average and contributed to drought conditions in the Amazon region at 17 times the average level, highlighting significant disparities in emission contributions.
- They emphasized that climate policies ignoring wealthy emitters will miss key opportunities to reduce harm and promote fairer climate action worldwide.
