The gases, which are transparent to solar radiation but retain and partially reflect back long wave heat radiations are called greenhouse gases. Recently, the concentration of green -house effect that is resulting in increases the mean global temperature. It is called global warming. The various greenhouse gases are CO2 (warming effect 60%) CH4 (20%)<CFC (14%) and nitrous oxide - N2O (6%)
