Why Scientists Retired the Dire Climate Scenario Used for Over a Decade
It’s rare for technical papers about climate modeling to kick off a heated public debate, or attract attention from the White House.
But that’s what happened recently after an international team of researchers published a major revision of the emissions scenarios used to study global warming.
When scientists try to model how hot Earth could get this century, they typically look at a range of possibilities for how much planet-warming pollution humans might pump into the atmosphere. These scenarios get updated every seven years or so.
In this latest update, the researchers abandoned a dire — and often criticized — high-emissions scenario known as RCP8.5 that has been prominently cited in thousands of climate studies over the past decade. The authors said the scenario was now “implausible” given recent energy trends.
That provoked online arguments among scientists. For years, critics of the high-emissions scenario had argued that it was always unrealistic, in part because it envisioned that countries would burn coal at absurdly high rates. They argued that any studies or news reports relying on that scenario exaggerated the risks of climate change. Why, those critics now asked, did the course correction take so long?
Because people aren’t buying into the Category 5 Doomsaying anymore
The Daily Caller notes the long, long, long history of the NY Times dropping fear p0rn with climate doom, using that exact RCP8.5, and notes
The NYT Editorial Board published “Climate Change Is Not Negotiable” in 2022, arguing for radical revisions to the U.S. economy and government to forestall global warming’s allegedly devastating consequences.
“Some of us have been talking about this for almost a decade. The fact that it took so long is a big problem. There will be significant consequences as the world unwinds from the extreme scenarios,” American Enterprise Institute Senior Fellow Roger Pielke previously told the Daily Caller News Foundation when asked about media usage of RCP 8.5. “Science is self-correcting but sometimes that process takes too long.”
And
I disagree: I think a goodly chunk of the climate (cult) scientists meant to use RCP8.5 exactly like that. It was always meant to institute more and more government, more and more taxes/fees, more Authoritarianism.
Even good news pisses off the Denier Cult. The scientists claimed changes in CO2 emissions makes the worst case scenario less probable!
Why are Teach and the Deniers upset?
Anyway, these vile, dishonest autocratic commies are so stupid that they undercut their own scam!!! Why would they do that? That would be like pedo-Don releasing the last 2.5 million trumpepstein files!
Not upset-just wondering why it took them so long…
They were following the data.
There was no “data”. RCP8.5 was from a computer model.
You are incorrect. The “data” = the rate of greenhouse gas emissions.

Because the money was drying up!
Common MAGAt misconception. Fact: Not every human endeavor is based on scrounging for dollars.

The IPCC 1990 assessment for temp 2030 was an increase of 1.4 C
So far it is 1.3 C
And of course those models are not predictions they are projections Scientists use “scientific” words
Emissions & Temperature Scenarios (2100):
Best-Case (1.5-1.8C): Requires aggressive, rapid cuts in global emissions to reach net-zero by 2050. While a best-case target under the Paris Agreement, achieving long-term stabilization below is becoming increasingly difficult. Highly unlikely.
Current Policies (2.6-2.7C): Represents the most realistic trajectory based on real-world actions and national pledges currently in place. Under this path, the world faces significant risks of severe, cascading climate impacts. Most likely.
High-Emissions (4.0C or higher): A worst-case scenario where global emissions continue to rise unchecked throughout the century. This pathway could lead to catastrophic environmental and economic consequences. Less likely under current environment.
The High-Emissions scenario is deemed less likely than previously projected.
So Rimjob what is actual surface temperature of the Earth today?
So Rimjob, the average global temperature in 1990 was approximately 59.8 degrees Fahrenheit (15.4 degrees Celsius).
Do you know what it was for 2025?
The predictions are probably false and the producers know that is the case, so they are actually liars, not just wrong about round off errors. All of their predictions are created for Western audiences. Asia and Africa and South America couldn’t care less about them. They all expect to be paid for “signing up”. None of the models acknowledge that increases in Chinese annual pollution totally invalidates all western nation savings put together. Nor do they acknowledge that annual forrest fires in one year erase all of the carbon saving ever pledged. So even if the “science” is right, the activity to fix the problem is futile. But it’s hard to collect a paycheck preaching futility. “Climate sciense” can only exist as a series of crises that are just around the corner, but never arrive.
