In 15 points of criticisms, the approaches of the basic model (albedo approx. 0.30, back radiation approx. 324 W/m², natural greenhouse effect approx. 33 Kelvin, etc.) used by the majority of climatologists are questioned and refuted. The author introduces a new model based on satellite measurements. With these, the observed global warming of approx. 1.2 Kelvin between 1850 and 2018 can be explained without the influence of CO2 by long-term cloud change (albedo change).
