Deseasonalized and detrended correlation analysis of mean monthly atmospheric CO2 concentrations and mean monthly surface temperature anomalies in the sample period 1958-2015 shows a statistically significant correlation that peaks when surface temperature lags atmospheric CO2 by four months. The correlation falls monotonically when CO2 lags temperature. The results are consistent with the theoretical two-way causal relationship between these variables. The effect of surface temperature on atmospheric CO2 appears to be stronger and it operates at a greater lag than the greenhouse effect of atmospheric CO2 on surface temperature.
