Global Climate Change - Essay ExampleHowever, weve but seen a glimpse of whats to come in both the near and far future. Its non a myth as deniers would have people believe or even a logical argument to be had. The dry lands climate is warming and man-made air pollutants atomic number 18 the chief(prenominal) cause. Factories and automobiles are spewing hundreds of tons of one C dioxide gas into the atmosphere faster than it can be naturally absorbed. Air defilement is not only affecting peoples lungs but every aspect of the natural founding as hygienic. This warning has been sounded by climatologists for at least 30 years the science has in, peer-reviewed and accepted by more(prenominal) than 98 percent of all scientists worldwide. The only question is do we have the political go out to do anything about it. Carbon dioxide is the main babys room gas affecting the undercoats temperature. The greenhouse effect is a naturally occurring typeface that provides a warm blan ket of air for the earth. It had served the planet well for thousands of millennia but excess gasses are causing the effect to become unbalanced. In much the same means as a man-made greenhouse are designed to grow plants operate, the earths greenhouse allows in sunlight but just enough to keep the temperature steady. Gases, such as naturally occurring snow dioxide and water vapor trap some energy but the rest 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 two other types of gasses ca utilize either forthwith 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 a tmosphere. Methane results from cattle flatulence therefore 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 extreme point 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 altered. 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 wave in Europe which left tens of thousands dead. The betting odds of this extreme heat wave occurring, based on records dating back 150 years, are about 1 in 10 million. (Shar, et al., 2004) When factoring in just a two 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 put down for each record low. That is phenomenal change and a clear indicator of a warming earth and the correlation of higher temperatures with extreme weather events. This increase in record high temperatures is occurring all oer the globe. A comparable two to one proportion of record highs temperatures to record lows have recently been enter in
