Greenhouse gases aren't trapping heat it but letting more in. The Earth's atmosphere blocks out most of the suns heat and harmful rays. With the gases polluting the world, the atmosphere is slowly weakening, letting more and more heat through.
absorbing heat emitted by earth.
They slow the loss of heat

greenhouse effect
The Greenhouse Effect. It happens when Greenhouse Gases (CO2) thicken the atmosphere and trap heat.
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.

Greenhouse gases.
Greenhouse gases in the atmosphere absorb and retain infrared radiation (heat) from the surface of the earth.

The atmosphere traps energy from the sun because in our atmosphere are greenhouse gases, like carbon dioxide (CO2) and methane. These three-atom gases absorb the heat rising from the earth's surface.
