Global Warming Essay -- Environmental Climate Change, Greenhouse Gase

Global WarmingGlobal warming is the progressive dawdling rise of the earths pop out temperature thought to be actd by the enhanced nursery nitty-gritty and responsible for changes in global climate patterns. The babys room effect is a term used to describe the roles of water vapor, carbon dioxide, and different trace gases in keeping the Earths surface warmer than it would be otherwise. These radiatively supple gases are relatively transparent to incoming shortwave radiation, but are relatively opaque to outgoing longwave radiation. The latter radiation, which would otherwise escape to space, is trapped by these gases within the lower levels of the atmosphere. The subsequent reradiation of some of the energy impale to the surface maintains surface temperatures higher than they would be if the gases were absent. There is concern that increasing con cen seasonrations of greenhouse gases, including carbon dioxide, (the carbon dioxide emissions are primarily caused by the use o f fogey 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 emergence in greenhouse gases over the past 200 years. Fossil fuels - coal, oil color and intrinsic gas - contain carbon. When they are burnt as a source of energy, they release carbon dioxide. The global demand for energy, primarily from fogy fuels, has grown to an average annual rate of approximately two per cent for almost two centuries - although the demand for energy varies considerably over time and among different regions. The burning of fossil fuels on a global photographic plate produces around 20 billion tonnes of carbon dioxide each year. About fractional of these emissions are absorbed by oceans and plants. The rest stays in the atmosphere. disforestation also contributes to increases in carbon dioxide, although on a much little scale, through the burning and decaying of vegetation. The reduction in vegetation also promoter that there are fewer plants to absorb the gas. Methane has various sources including herbivorous animals such as sheep and cattle that release it as a byproduct of digestion, sift paddies, land fills and forest fires. It can also enter the atmosphere from natural gas fields and coal mines. There are various sources of nitrous oxide including the use of fertili... ...We as a world community need to bad do something drastic to slow down the process of global warming, otherwise we may find ourselves in a situation where we cant turn back the hands of time and were suffering because of Global warming. We need to make indisputable that future generations can live a happy and uncomplicated liveness they shouldnt have to suffer from the impacts of Global warming that we (the current generation) have broadly speaking caused.
