• 13) Using the Planetary Energy Balance Equation, what should be the temperature of the Earth?
• S = 1366 W/m2
• A = 0.30 = 5.67 x 10-8 W/(m2 K4)

• 14) The mean surface temperature of the Earth is 288 K, why is the calculated temperature from the Energy Balance equation lower than the real temperature?
