Editors’ Note: Multiple mainstream media outlets such as The Washington Post, Bloomberg, Fox News, among others, have reported on the retirement of the worst-case emissions scenario, Representative Concentration Pathway (RCP) 8.5, from UN climate committee analyses, and President Trump’s reaction to it. This is a great victory for Climate Realism, as realists like those writing here have long explianed that RCP 8.5 is unrealistic, likely impossibly, and used exclusively to generate terrifying headlines. It will not be missed.
SCHAUMBURG, IL (May 19, 2026) – President Trump last weekend on Truth Social said “good riddance” to the United Nations Intergovernmental Panel on Climate Change’s (IPCC) most-alarmist climate model called RCP 8.5. Trump wrote: “The United Nations TOP Climate Committee just admitted that its own projections (RCP8.5) were WRONG! WRONG! WRONG! For far too long Climate Activism has been used by Dumocrats to scare Americans, push horrible Energy Polices, and fund BILLIONS into their bogus research programs.”
For years, the IPCC has relied heavily on a global warming scenario that assumed energy absorption in the atmosphere would reach 8.5 watts per square meter by 2100. This worst-case scenario has been used in countless academic papers and the media to predict a climate catastrophe soon if the use of fossil fuels is not dramatically reduced. The IPCC announced in April that this outcome has become “implausible.”
