Introduction
The natural process in which the earth traps the rays of the sun, warms itself to support life and radiates back the long wavelength rays is known as greenhouse effect. This maintains the temperature of the earth and insulates it from getting very cold. However, some harmful gases when present in the atmosphere reflect the longer wavelength rays or heat energy back to the earth. The heat energy which would have escaped into space when reflected to the ground, heats it even further. This process of trapping the harmful heat energy, sending it back to the earth and increase ...
