Worst-case climate scenario fades, warming does not

Worst-case climate scenario fades, warming does not

For years, a worst-case climate scenario served as a stark warning of what could happen if the world failed to curb fossil fuel use. A temperature rise of more than 4 degrees Celsius (7.2 Fahrenheit) by the end of the century would bring with it catastrophic consequences including deadly heatwaves, rising seas, crop failures and mass displacement. But a scientific paper published last month says that doomsday pathway — known as RCP8.5 and later …

IPCC Retires Its Most Implausible Global Warming Scenarios

"New and improved" climate models are offered, but the 'plausibility vacuum' remains. Furthermore, IPCC fails to acknowledge the damage to society and science done by its previous assessments. The post IPCC Retires Its Most Implausible Global Warming Scenarios first appeared on Le·gal In·sur·rec·tion.

Mainstream media offers misleading framing that ‘worst-case’ climate model scenario RCP 8.5 ‘has become implausible’ due to recent renewable energy trends

In lockstep, mainstream media (AP, Washington Post, NY Times) adopted the misleading framing that “worst-case” climate model scenario RCP 8.5 “has become implausible” due to recent renewable energy trends. However, RCP 8.5 was “never plausible” at its outset –> fatal flaw. https://t.co/HfmSe5Zk6I pic.twitter.com/boxqNmlRUb — Ryan Maue (@RyanWeather) May 19, 2026

The Worst-Case Emissions Scenario That Turned Out To Be A Lot Of Hot Air

Multnomah County’s $51 billion climate lawsuit against America’s energy producers was never going to age well. It was built on activist science, conflicted lawyers, and a worst-case scenario its own modelers admitted was implausible. This month, the bottom fell out. In April 2026, the international scientific committee that designs climate scenarios for the United Nations officially retired SSP5-8.5 — the corollary to the infamous RCP 8.5 — decl…
