Figure 5. The natural greenhouse effect (TS-TO) depicted
as the difference between the radiative equilibrium surface temperature
of the atmosphere of preindustrial times (centre panel) and that of a hypothetical
atmosphere with no radiatively active gases but the same albedo as at present
(left panel). The right panel of the diagram shows schematically the radiative
equilibrium temperature profile in the atmosphere resulting from the greenhouse
effect compared with the planetary temperature of 255K.
