Simulation proves that the anthropogenic CO2 portion in the atmosphere is 7.7 % - not 28 % as argued
Introduction: The common estimate of the increased amount of the atmospheric CO2 since 1750 is based on the CO2 concentration increase...
The downward flux by the atmosphere is the same as the real greenhouse effect. This flux is excatly the same as the sum of four energy fluxes: LW radiation absorption 155.6 + SW radiation absotpion 75.0 + Latent heating 90.8 + 24.2 = 345.6 W/m2
