Abstract: A new chemical process control systems engineering model of Earth’s atmosphere quantifies the effect of CO2 on Earth’s surface temperature. It uses the rigorous S-B radiant energy transfer rate law. The Earth’s surface and atmospheric temperatures are given explicitly as linear ordinary differential and algebraic equations; the only system properties needed are absorptivity and emissivity, five of which depend on CO2.
CO2 affects surface temperature by at least four mechanisms, one positive and three negative. CO2 decreases Earth’s global radiating temperature to space slightly. When atmosphere parameters increase by 1{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} due to CO2, surface temperature changes – 0.762C and atmosphere changes – 0.392C.
