New Paper Finds Effect of Human-Caused Carbon Emissions on Climate is “Non-Discernible”

Every now and then, a giant of modern science should be allowed to express himself in language that we all understand. In the informative Climate: The Movie, the 2022 Nobel physics laureate Dr. John Clauser thundered: “I assert there is no connection whatsoever between climate change and CO2 – it’s all a crock of crap, in my opinion.” While not expressing himself in such forthright terms, the Greek scientist Professor Demetris Koutsoyiannis might agree. He recently published a paper that argues it is the recent expansion of a more productive biosphere that has led to increased CO2 concentrations in the atmosphere and greening of the Earth. It is widely argued that changing atmospheric carbon isotopes prove that most if not all recent warming is caused by the 4% human contribution from burning hydrocarbons, but such anthropogenic involvement is dismissed by Koutsoyiannis as “non-discernible”. Koutsoyiannis is Professor Emeritus of Hydrology and Analysis of Hydrosystems at the National Technical University of Athens.
The isotope argument has been around for some time and has been useful in closing down debate on the role of human-caused CO2 and its supposed effect in causing a ‘climate emergency’. The carbon in living matter has a slightly higher proportion of 12C isotopes, and recent lowering levels of 13C, which accounts for 99% of carbon in the atmosphere, are used to promote the idea that it is caused by burning hydrocarbons. But Koutsoyiannis argues that the more productive biosphere has resulted in “natural amplification of the carbon cycle due to increased temperature”. He suggests this may be a “primary factor for the decrease in the isotopic signature 13C in atmospheric CO2”.
Clauser’s remarks, along with contributions from a number of other distinguished scientists, have led to widespread attempts to shadow-ban Martin Durkin’s Climate: The Movie in mainstream and social media. If Clauser and scientists like Koutsoyiannis are correct, there is no need for the Net Zero global collectivisation. Trillions of dollars can be taken back from the Climate Industrial Network to be used to solve more pressing environmental and social problems. In such circles, the idea that humans control the climate thermostat is regarded as little short of pseudoscience. In the film, the former Princeton professor William Happer says he can live with the descriptive suggestion “hoax”, although he prefers the word “scam”. Disregarding the role of natural forces and promoting a 50 year-old hypothesis – science speak for ‘opinion’ – that can’t even agree on the degree of warming caused by higher levels of CO2 – holds little attraction for these sceptical science minds.
