World's richest 10% caused two-thirds of global warming, study finds

The world's wealthiest individuals—specifically the top 10%—account for two-thirds of global warming since 1990, according to new research linking economic inequality to climate change. This study highlights how concentrated wealth exacerbates extreme weather events like heatwaves and droughts. Wealthy individuals and their investments drive significant portions of these climate impacts, with the richest 1% contributing disproportionately to severe weather worldwide. The researchers suggest that addressing the environmental responsibilities of high-income groups is crucial for effective climate action but face political and economic challenges in implementing solutions like wealth taxes.
