Private communication from Terigi Ciccone to John Shanahan
Where is the additional atmospheric carbon dioxide coming from? Terigi Ciccone August 24, 2022 John, you asked: “1) Where did the additional atmospheric CO2 come from? Fossil fuels or oceans and land off-gassing. (This is a scientific question with inferences for climate dynamics.) This can be answered when we have enough scientific data and knowledge. 2) Should politicians stop the use of fossil fuels because there is more atmospheric CO2? (This is a question of political power and preservation or destruction of many human lives.) This must be answered at the voting booth or by other means.” Sorry! I’m not going to get suckered into this UN/IPCC-inspired wild goose chase to waste our time and sow dissent among us Skeptics. Reading their F 7.3 of AR4, it’s apparent that the IPCC scientists don’t know the values of the natural sources and sinks of CO2. They put up cartoons with numbers, with nothing to back them up. Their only goal is to show that the main producers and consumers were balanced before humans came along with the human-made CO2. So, I took what they gave us and threw it back in their face. For example, below is a table I constructed for my book “A Hitchhiker’s Journey Through Climate Change.” I got the data provided from this IPCC-friendly site in 2019 https://skepticalscience.com/human-co2-smaller-than-natural-emissions-basic.htm. I went back there today, and the numbers are changed, even though they still refer to the source as “Figure 7.3, AR4.” The most important feature of this chart which I stress in the book, is how tiny the human CO2 is, 3.6% of total CO2, and the residual CO2 human-made portion is a laughable 0.06%.
