The main conclusion one arrives at the analysis is that CO2 has not a causal relation with global warming and it is not powerful enough to cause the historical changes in temperature that were observed. The main argument is the absence of immediate correlation between CO2 changes preceding temperature either for global or local changes. The greenhouse effect of the CO2 is very small compared to the water vapor because the absorbing effect is already realized with its historical values. So, the reduction of the outcoming long wave radiation window is not a consequence of current enrichment or even of a possible double ratio of CO2. The absence of correlation between temperature changes and the immense and variable volume of CO2 waste by fuel burning is explained by the weak power of additional carbon dioxide in the atmosphere to reduce the outcoming window of long wave radiation. This effect is well performed by atmosphere humidity due to known increase insolation and vapor content in atmosphere.
