1. The sun powers Earth's climate system by emitting shortwave radiation. SUN 4. The solar radiation absorbed by Earth's surface is converted to heat and emitted as infrared long wave radiation, This radiation has a longer wavelength than solar radiation, since Earth is cooler than the sun. 3. Some of the incoming solar radiation is reflected by Earth's surface and atmo- sphere back out to space. 2. Roughly half of this incoming solar radiation is absorbed by Earth's surface, warming it. 5. Some of the infrared radiation escapes into space, but most is absorbed by greenhouse gases in clouds and Earth's atmosphere. It is then reradiated back to Earth, upon which it warms the planet's surface and lower atmosphere. ATMOSPHERE EARTH Figure 18.25 How the greenhouse effect works.
