Greenhouse gases are a group of compounds that can trap heat in the atmosphere, acting as a thermal blanket for the planet.

Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere. The greenhouse gases emit infrared radiation ...

The warm Earth emits infrared radiation. Some gases absorb this radiation and re-emit it in all directions.
