"In Dr. Latour's presentation, physics, chemistry, mathematics, engineering, economics, history and ethics are deployed to identify the barriers to designing the thermostat to control Earth's atmospheric temperature by adjusting its CO2 input. He will explains that Earth's temperature is a chemical process system. Review of control system engineering of Earth's thermostat with anthropogenic CO2 in 1997 proved it will never work because it is an unmeasurable, unobservable and uncontrollable system. CO2 does not affect temperature; temperature affects CO2. There are no greenhouse gases in physics. CO2 is not a pollutant; it is green plant food."
