Nearly 160 Scientific Papers Detail The Minuscule Effect CO2 Has On Earth’s Temperature
By Kenneth Richard on 18. January 2024
We have updated our “Extremely Low CO2 Climate Sensitivity” scientific paper list with new papers added from 2022 and 2023 and some newly discovered papers from the past.
As of 2016 this list had only 50 papers on it (as indicated by the web address). In less than 8 years the list has grown to 159 (as of today).

160 Papers Find Extremely Low CO2 Climate Sensitivity
A few of the sample 2022 and 2023 papers are shown here.
Akasofu and Tanaka, 2022 (100 ppm CO2 = 0.2°C global temperature change)
In spite of various uncertainties in the above analyses, what is crucial here is that the combined temperature rise by the near-linear trend (0.07°) and the MDO (0.4°C, namely the range [amplitude 0.2°Cx 2]) between 1975 and 2000 is comparable with the observed temperature rise (0.5°C) between the same period. Therefore, within the accuracy of observations and analysis, it may be stated that the temperature rise caused by the greenhouse gases is much smaller compared with the combined rise caused by the two natural changes between 1975 and 2000, about 0.1°C, instead of 0.5°C. The above conclusion can be tested with the records in Figure 7, which shows the recent satellite temperature data up to 2018 (UAH and MSU; Humlum,10 together with the CO2 data from Mauna Loa. It can be seen that the rate of the observed temperature rise (0.5°C/25 years) between 1975 and 2000 has not been continued (see the dash line), in spite of the fact that the amount of CO2 is still rising rapidly. The rise of the temperature between 2000 to 2018 is at most 0.1°C as inferred in the previous section. We can show also here that the effects of the greenhouse gases are only one fifth of the IPCC assumption on the basis of the observed CO2. Based on Figure 7, it can be estimated that the rate of temperature rise by the greenhouse gases between 1975 and 2000 is a little more than 0.2°C/ 100 ppm, instead of 1.0°C/ 100 ppm by assuming that the temperature rise is caused by the greenhouse gases. On the other hand, the TRAC model based on Had CRUT4 model uses the rate equivalent to 0.5°C/100 ppm. Therefore, the rate of temperature rise by the greenhouse gases is overestimated in the past. Figure 8 shows clearly this fact many simulation studies predict, on the average. The temperature increase by 0.4°C (many of them even much higher than 1.2 °C) between 2000 and 2020, instead of the observed 0.1°C or so.
