Scientists Say Both Best and Worst Climate Warming Scenarios Are No Longer Likely
Scientists cut the top warming estimate to 3.5 degrees Celsius as cleaner energy and weaker fossil-fuel growth make earlier extremes less likely.
- An international team of climate modelers revised the United Nations Intergovernmental Panel on Climate Change worst-case scenario, deeming the extreme 4.5°C pathway implausible and setting a new 2100 upper-bound estimate at about 3.5°C.
- Developed in 2011, the previous RCP8.5 scenario relied on coal-heavy projections that became outdated as renewable energy costs dropped 90% over 15 years, prompting researchers to replace the single extreme pathway with seven more realistic models.
- Scientists emphasize this revision reflects a 'success story' in slowing warming rather than invalidating climate science, though they caution that significant impacts including rising seas and extreme weather remain likely under updated scenarios.
- President Donald Trump declared 'GOOD RIDDANCE!' on Truth Social, claiming the revision proves prior projections were 'Climate Alarmism nonsense' and a 'GREEN NEW SCAM,' while asserting his administration is based on 'TRUTH, SCIENCE, and FACT!'.
- Researchers warn that despite the lower upper bound, the world remains on track to surpass the 1.5°C limit set by the 2015 Paris Agreement, with experts stressing the update is not a reason for complacency.

‘Implausible’: Scientists quietly reverse climate doomsday prediction beloved by corporate media
Source link A bovine scarecrow on display Sunday, Sept. 28, 2025, at Peddler’s Village in Lahaska, Pennsylvania (Photo by Joe Kovacs) Climate scientists discarded an extreme global warming model frequently cited by news outlets in April after its predictions failed to materialize for over a decade. The Intergovernmental Panel on Climate Change (IPCC) found that Representative
Scientists have become a little more optimistic about global warming. US President Trump is confirmed in his scepticism about climate change. Experts disagree with him.Is climate change falling out? Climate researchers have mitigated their assumptions for the worst case in global warming and adapted their calculations. US President Donald Trump triumphed and evaluated the step as a rejection of "climate alertism". However, this is a misunderstan…
The advance of renewable energies and the slowdown in emissions growth reduced the likelihood of catastrophic warming of 4.5°C, although experts believe it is increasingly difficult to avoid exceeding the 1.5°C limit
AP Fact-Checker Condemns Trump For Celebrating Demise Of Climate Alarmism He Cited
Associated Press science writer Seth Borenstein traveled over to the fact-checking section on Monday to condemn President Trump for taking a victory lap on behalf of all people who do not subscribe to theories of apocalyptic climate change after the United Nations’s Intergovernmental Panel on Climate Change ruled a 2011 study’s “worst case scenario — called RCP8.5 — was implausible.” The problem for Borenstein was that in 2026, he said Trump was…
