Global Warming :: Greenhouse Effect, Climate Change

Global WarmingAbstract The worlds scientific experts agree that industrial and land use activities are having an adverse electric shock on our climate. Burning of fossil fuels such as coal, oil, and gasoline creates global warming pollution that acts as the glass in a greenhouse, reflecting heat screen toward the Earth and warming our climate. If we do not take steps now to reduce our emissions of global warming pollution, we will suffer serious environmental, public health, and scotch repercussions. We owe it to our next generations to leave them a healthy environment and economy. Industries must start reducing their emissions of global warming pollution before we seal the heap of future generations. The earths climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases (primarily carbon dioxide, methane, and nitrous oxide). Its functions are besides to the walls an d roof 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 mould of infrared radiation, 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, pee vapor, and ozone. The gases send infrared radiation back to the earths surface. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occuring greenhouse gases take on 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 solid waste, fossil fuels (oil, natural gas, and coal), and timber and wood products are burned. 2) Methane i s 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 outlandish and industrial activities, as well as during combustion of solid waste and fossil fuels. Greenhouse gases that are not naturally occurring include byproducts of foam production, refrigeration, and institutionalise conditioning called chlorofluorocarbons (CFCs), as well as hyrofluorocarbons (HFCs) and perfluorocarbons (PFCs) generated by industrial processes.
