The international communities are scared of catastrophic adverse effects of future climate change on different spheres of man and nature e.g.deglutination  and sea level change, submergence of island nations and major coastal lowlands, atmospheric dynamics including evaporation and precipitation, global radiation balance, photosynthesis and ecological productivity, plant and animal community, human health and wealth and many more. The major sources of global environmental problem have been identified e.g. rapid rate of industrialization and urbanization, population growth at alarming rate, advancement in productive technology, major land use changes etc. and effects are afoot for taking this alarming problem of global warming leading to climate change.
