These gases allow ultraviolet and visible radiation to penetrate and warm the earth, and then absorb infrared radiation emitted by the earth, and acts as a thermal blanket, trapping this heat in the atmosphere. Without the greenhouse effect the earth’s surface temperature would be around 50oF cooler than it is today (c.ref.5)....(short extract)
