Needless to say, mainstream media and science will try to ignore this sensational finding from Dr Soon and his fellow author Jonathan Cohler. If it is true, or accepted as a reasonable proposition, it will destroy the main scientific basis for Net Zero. Although atmospheric CO2 remains at denuded levels compared to the past at around 425 parts per million, activists have latched onto the recent healthy rise at a time of a 1°C bounce back in global temperature from a mini ice age to spin politicised poppycock about fireball Earth.
Examining the different isotope signatures of CO2 derived from fossil fuels and other forms of the gas released naturally into the atmosphere, the authors calculated that hydrocarbons could account for between zero and 26% of the recent increase.
The scientists also introduce a second piece of evidence to back up their finding. Five hundred years of growth layers on a Caribbean marine sponge show the various CO2 isotope signatures remaining remarkably constant despite an enormous expansion in the use and burning of fossil fuels. From all this, the authors state that virtually all the recent increase in atmospheric CO2 comes from natural sources, rather than the accumulation of fossil fuel emissions. The paper’s central conclusion is that the contribution of fossil fuel use is effectively zero.
In simple terms, this is how they did the maths. Carbon comes in two main forms known as C-12 and C-13. The more abundant form C-12 is lighter and accounts for about 99% of the total. Naturally occurring carbon contains both isotopes, but the proportion of one to the other varies slightly depending on where the carbon came from. Scientists have agreed a standard known as VPDB against which carbon samples can be compared. Carbon from fossil fuels is relatively low in C-13 with a typical signature of minus-28. This means that the ratio of C-13 to C-12 is 2.8% lower than the standard. Naturally released CO2 from the ocean and other sources are richer in C-13 with a signature of minus-8, or 0.8% lower than VPDB.
Soon and Cohler examined measurements of carbon isotopes from four atmospheric monitoring sites in Hawaii, Alaska, California and the South Pole, and used a mathematical technique known as the Keeling plot to estimate the isotope signature of the net addition of CO2 to the atmosphere. The results was a value of approximately minus-13.2. The authors note that if fossil fuels were responsible for most of the net increase, the resulting isotopes signatures would be much closer to minus-28. Thus, they argue that fossil fuels cannot be responsible for most of the recent increase.
The Net Zero promoting opinion is that isotope evidence proves that humans are primarily responsible for increased atmospheric levels of CO2, and by extension the rise has caused most if not all global warming for at least a century. This opinion is central to the ‘settled’ science of climate change. If the opinion is attacked and proved wrong in any significant way, the entire carefully constructed and curated propaganda around Net Zero collapses like a house of cards.
It is often assumed that the Earth’s atmosphere has been in balance in the recent past. But there are huge CO2 interactions, with both the oceans and the land releasing and capturing the gas. Volcanoes are also a large emitter of CO2, perhaps more than was first thought since many underwater mountains remain undiscovered. In other words, a period of stable CO2 atmospheric concentrations in the recent past does not prove that every source and sink was individually balanced. It just shows that the net effect was approximately balanced. And of course, the current levels of CO2 were rarely found in the past. Levels were much higher in the past with plants benefiting from its nutrients. Over the last 600 million years of life on Earth, the average level of CO2 in the atmosphere is seven times the near starvation level seen today.
In earlier work published in March last year by Soon and Cohler, it is noted that atmospheric CO2 molecules are exchanged with natural reservoirs on a timescale of approximately 3.5-4 years. In this paper, which was a critical reassessment of the anthropogenic CO2-global warming hypothesis, the authors interpret carbon isotope measurements as evidence that natural processes, rather than human emissions, dominate the recent increase in atmospheric CO2. Due to this continual recycling and short atmospheric residency, the authors suggest that it calls into question how much of the observed recent atmospheric rise in CO2 is attributable to human emissions.
Of course, questions are not allowed in polite climate politics and science, so the work of inconvenient questioning scientists such as Willie Soon and Jonathan Cohler will remain undebated and largely ignored in these captured Net Zero fantasising circles.

The UK Climate Change Committee (CCC), in its Seventh Carbon Budget, estimates that it’s Balanced Pathway requires capital investment averaging roughly £26 billion per year between 2025 and 2050 (peaking around £46 billion in 2029), adding up to an indicative cumulative requirement of about £650 Billion.
And NZ had stupidly adopted the same Net-Zero fantasy by the last two Govt’s.
The Act Party, led by David Seymour, has officially pledged to scrap New Zealand’s 2050 net-zero emissions target and ZERO CARBON Act as part of its climate policy platform.
Fingers crossed that the final election result favours sanity.
The his take has already been debunked. We were born with 2 ears, 2 eyes, but only one mouth. If only folks like this chap would take time to read what has already been found before jumping to the keyboard with his “breakthrough” findings!
Who cares any more, climate change is yesterday's apocalypse.
Now it is all about AI and how it will take control and kill us all. Please keep up.
Could someone, perhaps even anonymous@7.36, explain exactly what they are referring to, or just what they mean? Fatuous comments like that hardly add value to the debate.
IPCC quietly reveals RCP8.5 as being "implausible ".
Current COP conference in Turkey - 93 private jets flown in for delegates.
"A US$300 million luxury superyacht owned by a former Starbucks boss has been spotted in Auckland waters, berthed next to Jeff Bezos’ pleasure vessel." Sailed in, bollocks - dirty diesel.
If only the MSM would revert to dealing with news in the previously honorable neutral manner.
Dietrich Bonhoeffer wrote while incarcerated by the Nazi regime, Stupidity happens when people surrender their inner independence and stop thinking, questioning or weighing evidence for themselves and latch onto slogans, catchwords and group consensus.
This is very much in play today supported by our corrupt MSM.
It is not beyond belief that a large number of very naive people will believe the fairy stories being told by govts about climate change, just as they believed fervently in the Covid scam. It is not, however, possible that such delusions can affect our so-called ‘leaders’. There has to be other reasons for their deceit.
