A top-line claim in the latest U.S. government climate report is based on research funded by groups tied to Democratic donors.
The new National Climate Assessment claims the U.S. economy could take a 10 percent hit from global warming. However, that claim is based on research funded by groups founded by Tom Steyer and Mike Bloomberg.
The Bloomberg-Steyer-funded study found future temperature rise could cost “roughly 1.2% of gross domestic product per [additional one degree Celsius increase] on average.” At the most extreme high-end, that could add up to 10 percent of GDP by 2100.
Pielke called the use of such an extreme scenario “embarrassing” because it’s based on a future that’s 15 degrees Fahrenheit warmer — in other words, twice what the United Nations’ most extreme scenario projects.
