Scientific Course Correction: UN-Linked Committee Retires Famous Climate “Doomsday Scenario” As Implausible
the staff of the Ridgewood blog
Ridgewood NJ, For more than fifteen years, the most terrifying climate headlines across the globe—warning of rapidly vanishing coastlines, total global crop failures, and civilizational collapse—have relied heavily on a single data baseline. Known in academic circles as RCP8.5 (and its modern successor SSP5-8.5), this extreme scenario was long treated by media and politicians as our definitive, “business-as-usual” future.
Now, the scientific framework underpinning the United Nations’ Intergovernmental Panel on Climate Change (IPCC) has made a massive course correction.
The international scenario committee tasked with building the models for the upcoming IPCC Seventh Assessment Report has officially retired the worst-case pathway, declaring it “implausible.”

The Death of RCP8.5: Why the Projections Collapsed
The decision to ditch the doomsday scenario didn’t emerge from a political vacuum. Over the last decade, a growing contingent of climate researchers, economists, and policy analysts have pointed out that the extreme model had lost all touch with real-world data.
To achieve the catastrophic warming of nearly $4.8^\circ\text{C}$ ($9^\circ\text{F}$) projected by RCP8.5 by the year 2100, the model had to assume several highly unrealistic metrics:
-
A massive, fivefold global increase in coal consumption that far exceeds what geologists believe even exists in harvestable reserves.
-
Global population growth skyrocketing to over 14 billion people by the end of the century.
-
An absolute freeze on green technology, assuming the world would completely reject renewable energy advancements.
In reality, the global explosion of affordable solar, wind, and natural gas technologies has completely bent the global emissions curve downward. According to a newly released review paper by climate modelers, these rapid technological shifts and emerging global policies have rendered the highest-emissions models fundamentally obsolete.
“The Apocalypse Isn’t Around the Corner”
The retirement of these models has ignited a fierce debate over the sheer scale of global climate spending, which critics argue was justified using hyper-inflated, worst-case scenarios.
Roger Pielke Jr., a leading expert in climate policy research and senior fellow at the American Enterprise Institute, has spent years blowing the whistle on the scientific community’s over-reliance on flawed computer simulations. Writing on the landmark decision, Pielke noted:
“The climate apocalypse isn’t around the corner after all. That’s the upshot of a recent report from the international panel that supplies official ‘scenarios’ to researchers, governments and banks. It turns out that the most extreme assumptions about the future… are ‘implausible.'”
Pielke and his colleagues previously called the continuous use of RCP8.5 in thousands of academic papers “one of the most significant failures of scientific integrity in the twenty-first century.”
The New Realism: Where Is Global Temperature Heading?
With the apocalyptic scenario retired, the committee has introduced a new framework that projects a much more grounded future.
Instead of the cataclysmic $4.8^\circ\text{C}$ spike originally feared under the old doomsday assumptions, the new baseline models adjust the projected warming by 2100 down sharply to around $2.6^\circ\text{C}$ above pre-industrial levels.
[Old Catastrophic Target]: ~4.8°C Warming
[New Corrected Baseline]: ~2.6°C Warming
However, scientists stress that this is a “good news, bad news” situation. While the apocalyptic worst-case scenario has been ruled out, the rapid progress also means that the highly optimistic target of keeping global warming under $1.5^\circ\text{C}$ is now widely considered functionally infeasible.
The Political Fallout: Shifting the Urgency
The official retirement of the doomsday scenario changes the landscape of global climate politics. For years, Western governments have utilized the extreme baseline to justify trillions of dollars of aggressive, top-down economic interventions and green transition mandates.
Policy analysts suggest that if the absolute worst-case scenarios are no longer scientifically defensible, the frantic urgency driving aggressive, highly disruptive economic policies will naturally begin to fade. Moving forward, the conversation is poised to shift away from doomsday panic and toward practical, long-term risk management, infrastructure adaptation, and energy abundance.

The whole global warming scam was another way to raid the treasury.
When the thermometer didn’t cooperate with the scam it was renamed “climate change”
I never understood how the ocean level would rise substantially given the fixed amount of water in the atmosphere.
Now the same people who told you that your incandescent light bulbs were destroying the environment and wasting limited resources are building data centers the size of airports that consume more electricity and produce more environmental waste than anyone can imagine, and for absolutely 0 benefit to 99.9% of the world.
Thanks to the internet, the libtard Democrats no longer control the narrative
And thankfully President Trump calls them out on their lies.
