“From modern instrumental carbon isotopic data of the last 40 years, no signs of human (fossil fuel) CO2 emissions can be discerned.” –Koutsoyiannis, 2024
It is routinely claimed that a telltale sign human emissions (fossil fuels) have irrevocably altered the atmospheric CO2 concentration is a declining trend in carbon isotope 13 (δ13C), considered an interruption of natural carbon cycle processes. [emphasis, links added]
But new research examining isotopic data from four observation sites (South Pole, Mauna Loa, Barrow, La Jolla – regarded as “global” in their coverage) indicates there is no isotopic pattern consistent with a human fingerprint.
“The standard metric δ13C is consistent with an input isotopic signature that is stable over the entire period of observations (>40 years), i.e., not affected by increases in human CO2 emissions.”
In fact, not only has the input isotopic CO2 signature not been declining as proposed by those who believe humans are fully responsible for the increase in atmospheric CO2 concentration, but, according to multiple detection techniques using both modern data and paleo-data extending to the Little Ice Age (16th to mid-19th century), δ13C [input] has been increasing.
This directionality is the exact opposite of what is supposed to happen if fossil fuels were driving atmospheric CO2 increases.
“…for the longer subperiod lengths, 20 and 30 years, the tendencies are clearly increasing, opposite to the hypothesis that they are caused by fossil fuel emissions”
“…the trends are small and always positive, again contradicting the fossil fuel origin of the phenomenon”
“…from period B to C [1899-1976 to 1977-1997], we note an increase in δ13C [input, from -13.9‰ to -12.9‰], contradicting the fossil fuel origin of the phenomenon”

Agenda 2030 world population to 500 million and total control. One world government army and digital currency.
Ideological dogma is always unfalsifiable, so I am certain that Mann will have some kind of kooky defense for his Gaia god’s contrarian behaviour, and the MSM fruit-loops will lap it up. There is no cure for the stupidity of fools and no bulwark against insoluble arrogance. Mann et al will be the makers of their own ineluctable demise. Our real problem is surviving the destruction before that time comes.
All those Anti Fossil Fuels idiots should go live in Grass or Mud Huts without any electricity at all and see what its like to live in their imaginary world
So much for settled science! Climate hysteria as preached by the likes of Gore ,Suzuki and others including their prominent acolyte Greta T ,will soon enough join the witches of Salem and of Europe who were burned at the stake for sins including ‘meddling with the weather’ .King Canute learned his lesson soon enough but his woke descendants are
apparently still screaming STOP….climate change ….STOP ! Read your history,Mann,and be a man !
Let’s wait for Michael Mann to address this since he is the king of climate change. I’m sure he will have something to say on this.
His “Standard” reply:
“These people are not climate scientists and don’t comprehend all of the interactions involved. It takes a Noble Prize winner to do that. I will do my best to ensure that this misinformation is not published in any reputable journal.”
Or words to that effect.
Since I don’t want to be sued by Mann because of some flimsy complaint about defamation I’ll say nothing more.
