Bombshell: New Climate Study Shows Zero Carbon Impact on Warming
New peer-reviewed paper just dropped using 500 years of data and proving that ‘fossil fuel’ carbon contribution to rising atmospheric CO2 is effectively ZERO.
This damning study dismantles the entire IPCC/NASA/NOAA/EPA climate narrative that rests on a claim that just got mathematically falsified.The paper is titled “Mathematical Falsification of the Fossil-Dominant Hypothesis for Rising Atmospheric CO₂ Using the Keeling Relation”, by Jonathan Cohler and Willie Soon, dated 21 October 2026.
The authors show that the scientific establishment’s assertion that fossil-fuel emissions account for essentially all the modern increase in atmospheric CO₂ is mathematically incompatible with the carbon-isotope measurements used to support that very assertion.
The most interesting aspect is the contradiction between the accepted measurements and the conclusions drawn from them.
1. The paper’s argument, in plain English
The carbon fingerprint that supposedly changes everything
Carbon comes in different isotopic varieties. The paper concentrates on carbon-13 (¹³C), a slightly heavier form of ordinary carbon-12.
Different sources have different isotopic fingerprints:
| Carbon source | Approximate ¹³C signature |
|---|---|
| Fossil fuels | −28‰ |
| Ocean-released CO₂ | −8‰ |
| Volcanic carbon | −5‰ |
| Atmospheric CO₂ today | −8.5‰ |
| Intercept calculated by the authors | −13.2‰ |
The crucial point is that fossil fuels are relatively depleted in carbon-13. If large quantities of fossil carbon are entering the atmosphere, one would expect their distinctive isotopic fingerprint to become apparent.
The authors argue that it does not appear in the way the conventional explanation requires.
The Keeling relationship
The paper uses a mathematical relationship developed by Charles David Keeling, the scientist responsible for the famous Mauna Loa CO₂ measurements.
The authors examine a graph plotting carbon-13 isotope composition against the inverse of atmospheric CO₂ concentration. They claim that the intercept of this graph identifies the isotopic signature of the net carbon addition to the atmosphere.
The mathematical challenge to the conventional explanation
The authors then use a simple mixing equation to estimate the proportion of the net atmospheric addition attributable to fossil fuels.
Their calculation produces three particularly striking results:
-
Using their chosen range of natural carbon signatures, fossil fuels can account for no more than 26% of the net addition during the modern instrumental period.
-
Even allowing an extremely unrealistic natural carbon signature, they cannot obtain a fossil contribution greater than 47.1%.
-
Using their interpretation of the five-century historical record, they calculate a modern fossil contribution of approximately 1.3%, effectively zero within their stated measurement uncertainty.
The authors therefore go much further than suggesting that the IPCC has overestimated the contribution of fossil fuels.
They argue that the conventional attribution is mathematically impossible. The following is a polemical interpretation, rather than a neutral scientific abstract.
The CO₂ fingerprint that refuses to tell the official story
Imagine being told that the scientific evidence for the modern rise in atmospheric carbon dioxide is overwhelming. Fossil fuels, we are assured, explain essentially all of it. The conclusion is repeated by the IPCC, NASA, NOAA and governments around the world.
But what if the very measurements used by climate scientists contain a mathematical problem that has not been adequately confronted?
That is the provocative question raised by a new paper from Jonathan Cohler and Willie Soon.
Their investigation examines the isotopic fingerprint of atmospheric carbon dioxide. Fossil fuels have a distinctive chemical signature, containing relatively little carbon-13 compared with ordinary atmospheric carbon. This provides scientists with a potential means of identifying the origins of atmospheric carbon.
And here is where the authors’ argument becomes uncomfortable for the conventional narrative.
Using measurements from four internationally recognised monitoring stations, they calculate an isotopic intercept of approximately −13.2 per mille. They then compare this with the established isotopic signatures of fossil fuels and natural carbon sources.
Their conclusion is explosive: the calculated fingerprint does not support the proposition that fossil fuels dominate the net addition of carbon to the atmosphere.
Indeed, their mathematical treatment puts the maximum fossil contribution at 26% over the modern instrumental period. Their interpretation of historical records pushes the estimated contribution down to approximately 1.3%.
Even more intriguing is their claim that this isotopic intercept has remained remarkably stable for five centuries, despite the industrial world’s extraordinary increase in fossil-fuel consumption.
If their interpretation is correct, something fundamental is wrong with the conventional attribution of rising atmospheric CO₂.
This is not an argument based on an alternative temperature reconstruction, a computer simulation or a speculative theory about solar activity. It is an argument built around carbon isotopes, measurements, conservation of mass and elementary algebra.
The authors are effectively challenging climate science to explain why the isotopic arithmetic appears to produce a result so different from the official interpretation.
The question is not whether atmospheric CO₂ has increased. It plainly has. Nor is it whether humans burn enormous quantities of fossil fuels. They plainly do.
The question is whether the measurements actually establish the causal attribution claimed by the climate establishment.
