40 Years of Rising CO2 compared to Temperature

40 Years of Rising CO2 … 1940 to 1979. Officially CO2 measurements only started in the 50s, but I think one can extrapolate backwards.

CO2 didn’t have much effect. The Temperature trend over those 40 years was -0.026C per decade. About -0.1C for the 40 years.

Lets take a look at the same graph without the CO2 part.
