Title: Global Warming
Introduction
For over a hundred years, humans have understood the possibility of atmospheric warming due to anthropogenic carbon dioxide emissions. As early as 1896, Swedish chemist Svante Arrhenius predicted that a doubling of atmospheric carbon dioxide would raise average global temperatures by 4.95 degrees C (9.0 degrees Fahrenheit) (Valente, 1995). The greenhouse effect, a natural phenomenon that has allowed the development of life on earth, is thought by many scientists to have been radically altered by humankind’s impact on the composition of the atmosphere. The problem lies in humans’ effects on the dynamic nature of the heat exchange process of the sun, earth, and black space. These alterations threaten to transform the global environment. As one author imagined it, “The year is 2035. In New York, palm trees line the Hudson River … Phoenix is in its third week of temperatures over 130 degrees … Holland is under water. Bangladesh has ceased to exist … in central Europe and in the American Midwest, decades of drought have turned once fertile agricultural lands into parched deserts (Rifkin, 1988).”
Composition of Greenhouse Gases
Methane and carbon dioxide primarily constitute the greenhouse gases. They also consist of water vapor and trace amounts of other gases including ozone, nitrous oxide, and HCFCs. Greenhouse gases “trap” some of the sun’s infrared radiation within Earth’s atmosphere, similar to a greenhouse. As the
