Global Climate Change - Essay ExampleHowever, weve only seen a glimpse of whats to come in both the close and far future. Its not a myth as deniers would have people believe or even a debate to be had. The backgrounds climate is thaw and man-made air pollutants be the main cause. Factories and automobiles are spewing hundreds of tons of cytosine dioxide gas into the atmosphere faster than it can be naturally absorbed. Air pollution is not only affecting peoples lungs but every aspect of the natural world as well. This admonishment has been sounded by climatologists for at least 30 years the science has in, peer-reviewed and accepted by to a greater extent than 98 percent of all scientists worldwide. The only question is do we have the political will to do anything about it. Carbon dioxide is the main greenhouse gas affecting the earths temperature. The greenhouse effect is a naturally occurring event that provides a warm blanket of air for the earth. It had served the planet we ll for thousands of millennia but excess gasses are causing the effect to become unbalanced. In much the same way as a man-made greenhouse are designed to grow plants operate, the earths greenhouse allows in cheer but just enough to keep the temperature steady. Gases, such as naturally occurring carbon dioxide and water vapor trap some energy but the emit is bounced back into space. Excess carbon dioxide in the atmosphere absorbs additional heat allowing less back into space thus warming the earth at a faster rate than normal. Methane and nitrous oxide are dickens other types of gasses caused either directly or indirectly by mans actions but carbon dioxide, the result of fossil fuel emissions are the main culprit. This pollutant accounts approximately 85 percent of the excess greenhouse gas. Oil and gasoline used by automobiles and coal burnt in electric generating power plants are by far the main source of carbon in the atmosphere. Methane results from cattle flatulence therefo re the more beef people eat, the more methane is emitted into the atmosphere. In nature, animals, such as humans, breathe out carbon dioxide and growing plants breathe it in. This is not a contributor to climate change but coal and oil emissions are. (Walls-Thumma, 2012) Slight changes in the earths average temperature cause big changes in intensity and frequency of thorough weather events such as drought, rains, floods and tropical storms. With only modest temperature variations rare weather occurrences become more often and are more severe. Precipitation patterns are modify. Normally dry areas become drier and areas that usually experience moderate rains are deluged by heavy rains. Examining the way global climate change has altered the chances for a particular event occurring has been performed for extraordinary incidents such as the 2003 heat totter in Europe which left tens of thousands dead. The odds of this extreme heat wave occurring, based on shows dating back 150 years , are about 1 in 10 million. (Shar, et al., 2004) When factoring in just a cardinal degree temperature rise globally, the odds closed severely, more than quadrupling the chances. The intense weather occurrences that were expected to happen with greater frequency in a warming world are increasing. For example, just six decades ago record high temperatures were occurring at the same frequency as record low temperatures. Today, approximately two record highs are documented for each record low. That is phenomenal change and a clear indicator of a warming earth and the correlation of higher(prenominal) temperatures with extreme weather events. This increase in record high temperatures is occurring all over the globe. A comparable two to one proportion of record highs temperatures to record lows have recently been documented in
