Monthly means of Mauna Loa atmospheric CO2 concentrations are used in conjunction with surface temperature data from two different sources for the sample period 1979-2017 to test the validity and reliability of the empirical Charney climate sensitivity function. Detrended correlation analysis of temperature in five global regions from two different sources did not show that surface temperature is responsive to changes in the logarithm of atmospheric CO2 at an annual time scale. Correlations observed in source data are thus shown to be spurious. We conclude that the empirical Charney Climate Sensitivity function is specious because it is based on a spurious correlation.
