In this video I will explain Earth's natural thermostat that controls temperature of Earth's atmosphere call the Stefan Boltzmann Law. The Law states that the Power radiated from the surface depends on the Area times the Temperature of the area to the 4th power. Which means if the Temperature doubles the power will increase by 16 times. Note: Since Temperature is expressed in Kelvin the chances for the Earth's temperature to double is quite small (i.e. from 253K to 506K).
