Climate Impact of Increasing
Atmospheric Carbon Dioxide
J. Hansen
πR^2(1 - A)So = 4πR^2σTe^4
Te = [So(1-A)/4σ]^(1/4) (2)
Te = 255 K
The mean surface temperature is
Te = 288 K

based on solar radiation and blackbody radiation, the equation explained by Mr. Hansen shows that
if there were no greenhouse gases, the Earth’s surface temperature would drop to -18°C.
