T
here are countless climate models, which predict the impacts of the anthropogenic CO
2
emissions on the global earth
temperature. Because of the large number of influencing parameters used, these models are mostly very complex, so
the influences of the particular parameter can hardly be comprehended, i.e. the CO
2
concentration in the atmosphere. Due
to this fact, the greenhouse effect is described with simple analytical resolvable equations. Therefore, a simplified uniform
surface temperature of the earth is assumed. The radiation exchange between earth, clouds, space and the layers of gas between
is calculated with these equations, which were developed for the analogue radiation exchange in industrial furnaces. With
this model, the temperature profile in the atmosphere can be described relatively well. The CO
2
in the atmosphere acts as
a radiation shield, which increases the heat resistance against the outgoing long-wave radiation from the earth surface. The
known average temperature of the Earth was used to validate this model. When the CO
2
in the atmosphere is doubled, the
absorptivity increases slightly. Because of this increase, the temperature of the earth surface has to increase about 0.4 Kelvin to
compensate the increased heat transport resistance. Since 1860, the Earth's temperature has already risen due to anthropogenic
CO
2
emissions by 0.2 Kelvin. The measured increase of about 0.9 Kelvin is attributed to side effects caused by the CO
2
related
temperature increase. Therefore, a temperature increase of more than 0.4 Kelvin is predicted for the future. Without CO
2
, the
temperature of the Earth would be 4 K colder.
