The Greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. Greenhouse gases, such as carbon dioxide, methane, and water vapour, absorb and re-emit infrared radiation. This process traps heat within the atmosphere, reducing the loss of heat from the Earth by radiation, thus warming the planet.
Carbon dioxide absorbs strongly in infrared region and its presence in atmosphere decreases the loss of heat from earth by radiations. This is called :
