ENVIRONMENTAL IMPACT DUE TO THE DOUBLING OF GREEN HOUSE GASES THROUGH GLOBAL CLIMATE MODEL

Abstract: Anthropogenic carbon is responsible for both global warming and ocean acidification. Efforts are underway to understand the role of the ocean in a high CO2 world on a global context. Atmospheric carbon dioxide (CO2) concentration has continued to increase and is now almost 100 ppm above its pre-industrial level. Combining our reconstruction with the known history of the anthropogenic emissions gives us a more precise and detailed view of the terrestrial biosphere sink. The term Greenhouse Effect refers to the way certain gases trap heat in the atmosphere, much as the glass in a greenhouse prevents rising warm air from escaping. The greenhouse effect is a process where energy from the sun readily penetrates into the lower atmosphere and onto the surface of Earth and is converted to heat, but then cannot freely leave the planet. Due to the presence of certain greenhouse gases that trap heat, like carbon dioxide, methane, water vapour, and CFCs, the atmosphere retains the suns radiation and warms up the planet. By increasing the abundance of these gases in the atmosphere, humankind is increasing the overall warming of the Earth’s surface and lower atmosphere, a process called "global warming. CO2 is a greenhouse gas and as the IPCC report shows, its radiative effect is greater than that of all the other anthropogenic GHG gases. Our efforts have been to try and understand the impact of doubling the concentration of CO2 and thereby, understand the impacts of this increase on important physical processes of nature like evaporation, precipitation, snow cover, surface runoff, snow depth, etc. The ecosystem is surviving due to the balance maintained within all the components. Drastic increase in any component of this balance can prove to be quite destructive. Since the existence of biological cosmos is dependent upon such processes, we had attempted to understand the relationship between these components based upon the feedback generated.
