The Sun delivers radiant energy to Earth at a rate that averages approximately 1.3 kW per square metre of the cross-sectional area of Earth. If we assume that all of this energy is absorbed by Earth (i.e., that Earth has an emissivity of one), at what rate must Earth radiate energy if Earth’s temperature is to remain constant? What would that constant temperature be? (Note: The actual temperature of Earth is somewhat higher due to the greenhouse effect of the atmosphere.)
