These are gases that influence the temperature of our earth, and are causing the greenhouse effect. During the day, the sun shines through the atmosphere and is warming the surface of our earth. At night the surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases. There are naturally produced and man-made greenhouse gases, the so-called Kyoto Protocol defined those.
