greenhouse effect
type: Concept
definition: The ability of atmospheric gases to trap heat expelled from the earth's surface, commonly thought to be responsible for global warming. The greenhouse effect is also responsible for providing the earth with insulation, without which the planet would be too cold for most forms of life to exist.
