... The phenomenon responsible for trapping the heat inside the Earth¡¯s atmosphere is called the Greenhouse gas effect. The most effective Greenhouse gases include water vapour, carbon dioxide, methane, and nitrous oxide, as well as a variety of manufactured chemicals. Some greenhouse gases are emitted from natural sources; others are anthropogenic, resulting from human activities.
Greenhouse gases are accumulating in Earth¡¯s atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Action should be taken to reduce human greenhouse gas emissions, and sustain the Earth¡¯s balance between emission and absorption rates of such gases. Some argue that 98% of total global greenhouse gas emissions are natural, thus the human caused emissions are insignificant; however, there is enough evidence to suggest that the minute anthropogenic emissions have pushed the total level of greenhouse gas emissions above the natural absorption rates for these gases. There are four major greenhouse gases: water vapour, carbon dioxide, methane, and nitrous oxide, as well as a number of manufactured chemicals. Each of these sources of emission needs to be analysed to determine what needs to be done to reduce anthropogenic emissions.
Water vapour is a considerable contributor to the greenhouse effect. ... Humans interfere very little to the natural cycle of water vapour ¨C it is a natural emission generally beyond human control. ... Hence, controlling the carbon dioxide emission becomes an even more crucial fraction in combating the increasing greenhouse gas emission.
