State
The greenhouse effect is the process by which atmospheric gases absorb and re-radiate infrared energy that would otherwise escape to space, warming the surface above solar heating alone.
Show
A greenhouse gas molecule absorbs outgoing infrared radiation and re-emits part toward the surface, delaying its escape.
Watch for
The greenhouse effect is not a malfunction — a baseline effect lets Earth's surface support liquid water.
