In the last decade fundamental theoretical equations were developed for describing and understanding the global average radiative equilibrium state of the Earth-atmosphere system. It is shown that using the well-established laws of radiation physics the key climate parameters of the planet can be deduced theoretically, from purely astrophysical considerations and some plausible assumptions on the material composition of the planetary surface and the structure of the atmosphere.
It is also shown, that the Earth-atmosphere system is in radiative equilibrium with a theo- retical solar constant, and all global mean flux density components satisfy the theoretical expec- tations. The greenhouse effect predicted by the Arrhenius greenhouse theory is inconsistent with the existence of this radiative equilibrium. Hence, the CO2 greenhouse effect as used in the current global warming hypothesis is impossible. The greenhouse effect itself and the CO2 greenhouse effect based global warming hypothesis is a politically motivated dangerous artifact without any theoretical or empirical footing. Planet Earth obeys the most fundamental laws of radiation physics.
