Essay on Global Warming Essay

Global warming is the term employ to describe a gradual increase in the bonny temperature of the Earths melodic line and its oceans, a change that is believed to be per sliceently changing the Earths mood. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. The twenty-ninth century is experiencing a continued increase of Earths average atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is world(a) warming is affecting the natures balance and has a extensive impact on life like continued heat waves, and choppy occurrence of storms and floods. Dont we see time to time the epidemics that ar devastating to human life and the flooding of the farmlands that puts economy in a deep hole?Scientific evidence indicates that since 1950, the worlds climate has been warming, primarily as a result of emissions from non -stop sunburn of fossil fuels and the ruining of tropical forests. Since the in dustrial revolution till this day, there is a unending emission of the deoxycytidine monophosphate into the atmosphere, everything we do we leave carbon footprints. It is a man made capture of the global warming. The global emissions jumped 3 percent in 2011 and be expected to jump another 2.6 percent in 2012, researchers reported. The babys room effect is a process by which the greenhouse gases absorb thermic radiation these are then reradiated in all directions. But when nigh of these radiations come back to the surface and lower atmosphere, it causes increase in the average surface temperature spark advance to global warming. Global warming CausesThe causes are umteen of which the main culprit is the increase in the greenhouse gases that is produced by burning fossil fuel and disforestation, thus intensifying the greenhouse effect leading to global warming. The four main contributors of the greenhouse effect are, water vapor, carbon dioxide, methane and ozone. Mining for coal and oil releases methane in the atmosphere. More ever the escape from natural gas fields and landfills are additional source of methane. uppity cutting down of the trees is another factor causing global warming. When deforestation legislates the efficiency by which carbon dioxide is stored and oxygen released by the green plants are decreased to a huge appreciate in turn causing increased concentration of carbon dioxide that leads to increased greenhouse effect.The nitrous oxide from fertilizers, gases used for refrigeration and industrial processes are other factors that cannot be forgotten as the cause of Global Warming. Another source of methane is methane clathrate, a compound containing life-sized amounts of methane trapped in the crystal structure of ice. As methane escapes from the Arctic seabed, the rate of global warming will increase significantly. Ice caps and glaciers reflect sunlight, gritty high temperature sun -rays back into space away from the Earth. Whe n these icecaps are upstage the earth gets warmer as the dark oceans absorb much thermal radiation from the sun. Some regions may be wet with rain and several(prenominal) areas will suffer drought due to global warming.The climatic changes happen due to global warming. Seasonal changes are unpredictable unexpected thunderstorms king result as mentioned earlier. The burning of wood (should be reduced to a great extent) releases oxidizable carbon to the atmosphere whose presence in greater amount causes the elevation of temperature. There is strong evidence that emissions of chlorofluorocarbons (CFCs) were the major cause of the recent abnormal warming. Like carbon CFC do not trap heat but in the presence of UV rays the chlorine gets detached from CFC, drifts up into the stratosphere and these unattached chlorines catalytically convert Ozone molecules into Oxygen molecules depleting the ozone layer.
