Global Warming Essay -- Environmental Climate Change, Greenhouse Gase

orbiculate WarmingGlobal warming is the progressive gradual rise of the earths rally temperature thought to be caused by the elicitd babys room effect and trusty for changes in global climate patterns. The greenhouse effect is a frontier used to describe the roles of water vapor, coulomb dioxide, and other trace splashes in keeping the Earths surface warmer than it would be otherwise. These radiatively active gases ar comparatively transparent to incoming shortwave radiation, but are relatively opaque to outgo longwave radiation. The latter radiation, which would otherwise escape to space, is trapped by these gases within the set about levels of the atmosphere. The subsequent reradiation of some of the energy back to the surface maintains surface temperatures higher(prenominal) than they would be if the gases were absent. thither is concern that increasing concentrations of greenhouse gases, including carbon dioxide, (the carbon dioxide emissions are primarily caused by th e use of fossil fuels for energy) methane, and manmade chlorofluorocarbons, may enhance the greenhouse effect (this is called the enhanced greenhouse effect) and cause global warming. There are several important factors that have caused the increase in greenhouse gases over the past 200 years. Fossil fuels - coal, oil and natural gas - contain carbon. When they are burnt as a source of energy, they freeing carbon dioxide. The global demand for energy, primarily from fossil fuels, has grown to an honest annual rate of approximately ii per cent for almost two centuries - although the demand for energy varies considerably over succession and among different regions. The hot of fossil fuels on a global scale produces around 20 billion tonnes of carbon dioxide each year. About half of these emissions are absent by oceans and plants. The rest stays in the atmosphere. De timbreation also contributes to increases in carbon dioxide, although on a much smaller scale, through the import unate and decaying of vegetation. The reduction in vegetation also means that there are fewer plants to absorb the gas. Methane has various sources including herbivorous animals such as sheep and kine that release it as a byproduct of digestion, rice paddies, land fills and forest fires. It bay window also enter the atmosphere from natural gas field and coal mines. There are various sources of nitrous oxide including the use of fertili... ...We as a world community need to seriously do something forceful to slow down the process of global warming, otherwise we may understand ourselves in a situation where we cant turn back the hands of time and were defending because of Global warming. We need to make sure that future generations can live a happy and uncomplicated life they shouldnt have to suffer from the impacts of Global warming that we (the current generation) have mostly caused.
