greenhouse effects

Atmospheric heat trapping

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat from the sun, warming the planet's surface.

These gases—primarily carbon dioxide, methane, and water vapor—act like the glass panels of a greenhouse, allowing sunlight in but preventing heat from escaping back into space.

Without this natural phenomenon, Earth would be too cold to support most life.

The term now frequently appears in discussions of climate change, where human activities have intensified the effect by increasing atmospheric carbon dioxide levels.
