2. The Greenhouse Effect Solar radiation passes through the clear atmosphere Some solar radiation is reflected by the Earth and the atmosphere Some of the infrared radiation passes through the atmosphere, and some is absorbed and re-emitted in all directions by greenhouse gas molecules. The effect of this is to warm the Earth’s surface and the lower atmosphere.
