Climate change is a natural and continuous process. But recent relatively rapid change in climate occurs due to anthropogenic activities which makes alarming attention because it contributes largely to global warming by affecting the greenhouse gases (GHGs) and aerosols. GHGs mainly CO2, methane, nitrous oxide CFC11, CFC12, HCFC22and HFC23 with different global warming potential accumulate in atmosphere and increase in concentration over time creating the so called “greenhouse effect”. This effect can alters balance by transmitting incoming solar radiation but absorbing outgoing thermal radiation from surface. |
