The phenomenon of keeping the earth warm due to presence of certain radiatively gases in the atmosphere is called green house effect (Fourier, 1827). The name is based after a similar warmer interior in a glass-enclosed green house where glass panes, CO2 and water vapour allow the solar radiations to enter but prevent the escape of long wave heat radiations. CO2 and N2O are the major causes of 'green house effect'. CO2 contributes 60% of total global warming. N2O contributes 6% to green house effect.
