8.2: Earth''s Energy Balance

The warmed Earth is no exception, and about 16% of the original solar energy is radiated from the Earth to the atmosphere (figure (PageIndex{1})). When sunlight warms a surface such as a paved surface, a patio, or deck, the warmer surface emits more thermal radiation, which is a type of IR radiation.

NASA SVS | Earth''s Energy Budget Global View

Reigning on Earth''s Climate - Only about 70% of the solar energy that reaches Earth is absorbed, while the other 30% is reflected back into space by atmosphere and aerosols, ocean/land and clouds. A closer view reveals a delicate balance between absorption and reflection as well as a release of energy by rocks, air and sea warming …
