CO2 has almost no effect on Global Temperatures, It is a minor factor

Carbon dioxide change has no significant influence

The influence that CO₂ has on AGT can be calculated by including ‘C’ in Equation (1) of Reference 2 as a coefficient to be determined. The tiny increase in R² demonstrates that consideration of change to the CO₂ level has no significant influence on AGT. The coefficients and resulting R² are given in Table 1.

Table 1: A, B, C, D, refer to coefficients in Equation 1 in Reference 2

For those with inquiring minds.... The real answer to Global Temperatures is:

1) Mostly sunspots
2) Prediction improved by considering a well known Ocean Temperature Oscillation

If we ignore CO2, temperatures can be well predicted by sunspots alone.
