Overview
- Researchers writing in Geoscientific Model Development said the high‑emissions pathway SSP5‑8.5 is not a plausible 21st‑century outcome and urged using a narrower range of scenarios.
- The pathway, earlier labeled RCP8.5, had served as the IPCC’s worst‑case benchmark that assumed very high fossil fuel use and projected severe warming, higher seas, and crop losses.
- After reports on the shift, President Trump posted on Truth Social that the U.N. climate committee’s projections were wrong and he attacked Democratic energy policies.
- Hillary Clinton responded at the Clinton Global Initiative, calling the hoax claim total disinformation and saying it misleads the public.
- EPA Administrator Lee Zeldin defended the president in a Fox News interview, saying climate rules pushed by the left cause economic pain.
