A major climate study's retraction due to data errors lowers projected global income loss by 2050 to 17%, yet confirms climate change still threatens economies, especially low-income nations.
A 2024 study on climate change’s economic impact, originally published in Nature and widely cited in global policy, has been retracted due to data errors, particularly in Uzbekistan’s economic data from 1995 to 1999, and underestimation of uncertainty.
Researchers from Germany’s Potsdam Institute revised their estimate of global income loss by 2050 from 19% to 17% and reduced the probability that climate damage costs will exceed resilience investments from 99% to 91%.
Despite the adjustments, the core finding remains: unchecked climate change will severely harm the global economy, with low-income nations bearing the brunt.
Experts confirm that climate risks are already increasing costs, such as U.S. home insurance premiums, and underscore the need for urgent action.
The revised findings are not yet peer-reviewed.
