Research - Essay Example g is an issue that need to be tackled holistically by all people and the relevant authorities without blaming each other for the current worsening conditions. Technically, global warming is a problem that emanates from the presence of too much carbon dioxide in the atmosphere. This acts as a blanket which traps heat, thereby warming the planet. Other gases such as methane and nitrous oxide have the same effect. Therefore, burning of coal, oil, and natural gas for energy leads to accumulation of carbon dioxide gas in the atmosphere. Scientific evidence indicate that an increase in global average temperature by 3.6 (F) poses a major risk to the natural systems and the existence of the human beings (Smith 18). Scientists have discovered that methane is mainly released by landfills and various agricultural practices such as use of nitrous oxide from fertilizers. In addition the gas is released through both industrial and refrigeration processes. Greenhouse gas emission is one of the major causes of global warming; global warming, thus, results from the greenhouse effect. The latter involves a process through which the emission and absorption of infrared radiation through the gases in the earth’s atmosphere, which warms the lower atmosphere and the surface of the earth (Smith 26). On the surface of the earth, the naturally occurring greenhouse gases have a mean warming effect of approximately 59˚F. Without the existence of the Earth’s atmosphere, the average temperature on the planet would be lowered to the freezing point. The major greenhouse gases exist in terms of water vapor that results in about 30-70% of the greenhouse effect, which leads to global warming. Scientists have pointed out that carbon dioxide causes 10-25%; methane causes 5-10%; and the ozone causes 3-8% of the greenhouse effects. Scientists have also pointed out that human activity that began during the times of Industrial Revolution in the United States and Western Europe increased the level
