Since the middle of the last century, energy consumption, and also the concentration of the atmospheric CO2 have been increasing. the increase in the atmospheric CO2 concentration has been deduced to be mainly due to the burning of fossil fuel sand cement production. This increase might cause heating of the lower atmosphere, co-called the green house effect. In the present paper, the atmospheric CO2 concentration and the mean air temperature for the Northern Hemisphere are reviewed since 1860, and they are examined as a function of amounts of CO2 emitted. Both the atmospheric CO2 concentration and the mean air temperature have increased with fossil fuels consumption for the period between 1860 and 1940. Since1960, the atmospheric CO2 concentration has been increasing with fossil fuels consumption, but the mean air temnperature, On the contrary, has lowered. Both the atmospheric CO2 concentration and the mean air temperature have been roughly constant from 1940 and 1960. Because the atmospheric CO2 concentration（ppmv）, Z, is corelated with fossils fulel consumption (Gt CO2/y), X, and mean air temperatu-re（℃）, y, the following relationshipis derived by least squares calculation : Z＝1.216x＋12.985（y－15.00）＋306.57 The standard deviation is 2.93 ppmv for z.
