Climate change is currently an eminent theme in politics. Thereby, so-called greenhouse gases such as CO2 are considered as the real cause for the temperature rise of the global atmosphere. This theory traces back to measurements of Tyndall at the end of the 19th century which revealed that CO2 absorbs thermal radiation, in contrast to N2 and O2, the main components of the air, which do not absorb. Subsequently, Arrhenius tried to theoretically implement the Stefan-Boltzmann law, which meanwhile became known, assuming that the atmosphere is warmed up by the black-body radiation of the Earth surface, but solely due to the CO2 and to similar IR (infrared) absorbing greenhouse gases such as CH4. This means: The atmosphere would not be warmed up if no CO2 or other greenhouse gases were there. Thus the temperature of the atmosphere would be identical with the temperature of the absolute zero. After the Second World War, this approach was continued by Plass and others, based on IR- spectro
