Earth's albedo is 0.39. The total amount of radiant energy emitted (rather than reflected) by Earth is thus:

Question

Quizplus · Accepted Answer

Earth's albedo of 0.39 means that 39% of the incoming radiation from the Sun is reflected back into space. Therefore, the amount of radiant energy emitted by Earth is 61% of the incoming radiation from the Sun, which is not greater than 100%. The greenhouse effect does not cause Earth to emit more radiant energy than it receives from the Sun, as it simply traps a portion of the incoming radiation and prevents it from being immediately emitted back into space.
