The World Energy Consumption Dictates the Earth Climate

Basic thermodynamic calculations lead to the reliable result that the primary energy consumption (PEC) is the main origin of the observed temperature increase of the earth climate. The CO2 greenhouse gas influence plays comparably no decisive role. Based on the second law of thermodynamics the entropy changes since 1750 were calculated up to 2100 considering the exponential increase of the world primary energy consumption PEC and the exponential growth of the world population, taking into account the so called greenhouse factor Beta for the radiation equilibrium earth atmosphere/outer space and the energetic efficiency Zeta. The calculations result in an exceptional increase of world temperature. A revision of the world temperature and sea level prognoses etc. published so far by the IPCC is absolutely necessary. It is pointed out that this temperature increase is entirely independent of the fuel type, i.e. fossil oder renewable. Based on the thermodynamic results and the relaxation time of the CO2 it is almost impossible to reduce the earth surface temperature with the so far planned mitigation measures for reducing CO2 within the time given for man. The only possible measures to save live on earth will be a radical cut down of the consumption of primary energy of the world, both fossil energy as well as renewable energy. A method to limit the use of primary energy could be the introduction of an entropy tax on the basis of a world wide philosophy of an Entropy Identity.
