	Greenhouse gases are relatively transparent to short-wave infrared radiation. This means they allow sunlight to enter the atmosphere and heat the Earth’s surfaces. These surfaces then re-radiate that heat as long-wave infrared radiation, which greenhouse gases tend to absorb rather than transmit. As a result, heat accumulates in the atmosphere causing a warming process known as the greenhouse effect.		Greenhouse gases are relatively transparent to short-wave infrared radiation.
