Revise: Biological Consequences of Global WarmingGreenhouse gases, including carbon dioxide and methane, absorb some of this outgoing radiation and re-radiate energy in different directions, including back towards the surface. This natural greenhouse effect keeps Earth warm enough to support life.
- Revise: Greenhouse Effect
The natural warming of the Earth's surface and atmosphere because greenhouse gases absorb outgoing infrared radiation and re-emit some towards the surface, reducing energy loss to space.
