Mitigation Strategies and Solutions of Global Warming

It must focus on controlling the emission of greenhouse gases, the development of alternative fuels like biofuels and stronger research efforts and government support in the national and international arena.
Global warming is a phenomenon in which the temperature of the atmosphere rises significantly. It is also defined as the process of observed and projected increases in the average temperature of the Earth’s atmosphere and oceans (Christianson, 1999). This happens due to the emission of greenhouse gases like carbon dioxide, methane, nitrous oxide and chloro flouro carbons from industries and other human activities. Greenhouse gases are those gases that contribute to the greenhouse effect. The main source of greenhouse gas is the burning of fossil fuels resulting in the emission of carbon dioxide (Kaplan, 2002). These gases trap the heat and they will not allow the heat radiation to go back into the space resulting in higher temperatures. It was noticed that water vapor causes about 36-70% of the greenhouse effect on Earth and hence it can be considered as a major greenhouse gas. Similarly, carbon dioxide, methane, and ozone result in 9-26%, 4-9% and 3-7% of global warming respectively. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influence of the various gases is not additive. Some other greenhouse gases like sulfur hexafluoride, hydrofluorocarbons and perfluorocarbons also contribute significantly to global warming.
The main concern of global warming is its phenomenal effect on temperature which results in detrimental effects for human basic existence. The major proportion of the enhanced temperature during the last 50 years is resulted by the increase in the atmosphere of greenhouse gas concentrations like water vapor, carbon dioxide (CO2), methane (CH4) and ozone (O3). These greenhouse gases, in general, absorb the longwave radiations and don’t allow them to escape back into the space resulting in the greenhouse effect and global&nbsp.warming (Moore, 1998).
