US EditionMajor Climate-GDP Study Under Review After Facing Challenge
CALIFORNIA, USA, AUG 6 – Stanford researchers identified data errors in a major study, revising the estimated climate change impact on global GDP to about one-third of the original 62% projection.
- Amid replication efforts, Stanford University researchers released Wednesday a re-analysis that found the projected climate impact to be about three times smaller after excluding an Uzbekistan data anomaly.
- Using datasets from 83 countries, climate scientist Maximilian Kotz led research published in Nature last year warning of a 62 percent projected global GDP hit from unchecked climate change.
- Amid replication checks, Nature added an editor’s note in November 2024 after Solomon Hsiang identified anomalies in Uzbekistan data that mismatched World Bank figures.
- The journal told AFP it may culminate in a retraction with "further information to share soon," the editor said.
- In the broader context, both the original authors and the Stanford team hope transparency will bolster public confidence in the scientific method.

Major climate-GDP study under review after facing challenge
A blockbuster study published in top science journal Nature last year warned that unchecked climate change could slash global GDP by a staggering 62 percent by century's end, setting off alarm bells among financial institutions worldwide.
The original report was published in April 2024 in the journal "Nature" and the results of peers and key figures have now been reviewed.
The prestigious scientific journal Nature could retract the second most cited climate study of last year, AFP reports, citing errors in calculations that significantly affected the results. The original findings were so surprising that they sparked a strong reaction in the scientific community and led to a review of the study. The review found several errors, the authors admitted the errors they found, and even welcomed them as evidence that sci…
