CO2 is known as a greenhouse gas. It is able to trap and retain infrared radiation in the earths atmosphere thereby causing a gradual rise in the temperature of the earth. If this doubled concentration of CO2 is sustained over a long period of time, it will eventually lead to melting of polar ice caps and consequent flooding. Gradually, the earth would be destroyed due to the scorching heat and attendant flood.
