Greenhouse effect - Process whereby greenhouse gases released into the atmosphere cause heat to be trapped in the atmosphere rather than escaping into space. The greenhouse gases form an insulating blanket around the planet. This blanket allows light and heat from the sun through, but prevents some of the heat, which radiates back from the earth from escaping. The same effect occurs in greenhouses, hence the name. The effect is natural and vital to current life forms on earth. Without it, the planet would be frozen.
