Explanation

Greenhouse effect is the phenomenon of keeping the earth warm is due to the presence of certain gases in the atmosphere (Fourier, 1827). The name is based warmer interior on the effect in a glass-enclosed greenhouse where glass panes, `CO_(2)` and water vapour allow the solar radiations to enter, but prevent the escape of long wave heat radiations. `CO_(2)` and `N_(2)O` are the major cause of 'greenhouse effect.' `CO_(2)` contributes `60%` to total global warming, `N_(2)O` contributes `6%` of greenhouse effect.
