Claim: Dai Ato's research found that atmospheric carbon dioxide levels rose by approximately two to three parts per million for every 1°C increase in sea surface temperature
85%Based on my research, I can verify this claim about Dai Ato's research findings.
Verification:
- Dai Ato, an independent researcher from Osaka, Japan, published a study titled "Multivariate Analysis Rejects the Theory of Human-caused Atmospheric Carbon Dioxide Increase: The Sea Surface Temperature Rules" in the journal Science of Climate Change12
- The study used multiple linear regression analysis with annual changes in atmospheric CO₂ as the objective variable and sea surface temperature (SST) as an explanatory factor2
- The research found regression coefficients ranging from B = 1.964 to B = 2.406 ppm per 1°C increase in SST, depending on the data source and time period used12
- These values fall within the claimed range of "two to three parts per million" per 1°C, though closer to the lower end of that range21
Key context:
- The study controversially concluded that human CO₂ emissions were not a statistically significant determinant of atmospheric CO₂ increases in the regression models, while SST was12
- This finding contradicts the established scientific consensus that human fossil fuel emissions are the primary driver of rising atmospheric CO₂3
Overall validity: 85%
The claim accurately reports the approximate range of regression coefficients found in Dai Ato's research, though the upper bound of "three parts per million" slightly overstates the maximum value found (2.406 ppm/°C).
