ultra violet radiation has a higher energy level than visible light, and infrared (IR) radiation has a lower energy level. Some of the sun's incoming radiation is absorbed by the atmosphere, the oceans and the surface of the Earth.
Much of it, however, is reflected out to space as low-energy infrared radiation. For Earth's temperature to remain stable, the amount of incoming solar radiation should be roughly equal to the amount of IR leaving the atmosphere. According to NASA satellite measurements, the atmosphere radiates thermal IR energy equivalent to 59 percent of the incoming solar energy.
Along with other gases like methane and nitrous oxide, CO2 acts like a blanket, absorbing infrared radiation and preventing it from leaving the atmosphere. The net effect causes the gradual heating of Earth's atmosphere and surface.
