Global Warming :: Greenhouse Effect, Climate Change

Global meltAbstract The worlds scientific experts agree that industrial and land use activities be having an adverse impact on our climate. Burning of fogy fuels such as coal, oil, and gasoline creates spheric warming pollution that acts as the glass in a nursery, reflecting heat back toward the Earth and warming our climate. If we do not take steps now to reduce our emissions of global warming pollution, we pass on suffer serious environmental, public health, and economic repercussions. We owe it to our next generations to expire them a healthy environment and economy. Industries must start reducing their emissions of global warming pollution before we seal the fate of future generations. The earths climate is predicted to change because homosexual activities be altering the chemical composition of the melodic phrase through the buildup of greenhouse gases (primarily carbon dioxide, methane, and nitrous oxide). Its functions are similarly to the walls and chapiter of a greenhouse, allowing sunlight to enter, but preventing heat from escaping. Sunlight passes through the atmosphere and heats the earth?s surface. The earth gives off heat energy, in the micturate of infrared irradiation, which travels back toward the atmosphere. Instead of going into space, some of the infrared radiation is trapped by greenhouse gases (Schneider, 1989). The main greenhouse gases are carbon dioxide, methane, water vapor, and ozone. The gases send infrared radiation back to the earths surface. Some greenhouse gases occur inherently in the atmosphere, while others result from human activities. naturally occuring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases 1) Carbon dioxide is released to the atmosphere when self-colored waste, fossil fuels (oil, natural gas, and coal), and wood and wood products are burned. 2) Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock. 3) Nitrous oxide is emitted during agricultural and industrial activities, as healthful as during combustion of solid waste and fossil fuels. Greenhouse gases that are not naturally occurring include byproducts of foam production, refrigeration, and air conditioning called chlorofluorocarbons (CFCs), as well as hyrofluorocarbons (HFCs) and perfluorocarbons (PFCs) generated by industrial processes.
