Essay on Global Warming Essay Example for Free

Essay on world-wide Warming EssayGlobal warming is the term used to describe a gradual profit in the average temperature of the Earths atmosphere and its oceans, a change that is believed to be permanently ever-changing the Earths climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. The 29th one C is experiencing a continued increase of Earths mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is global warming is affecting the natures balance and has a capacious impact on life like continued heat waves, and sudden occurrence of storms and floods. Dont we see time to time the epidemics that be 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 terminates and the razing of trop ical forests. Since the industrial revolution till this day, thither is a constant emission of the vitamin C into the atmosphere, everything we do we leave carbon footprints. It is a man make cause of the global warming. The global emissions jumped 3 percent in 2011 and ar expected to jump another(prenominal) 2.6 percent in 2012, researchers reported. The greenhouse prepare is a process by which the greenhouse gases absorb thermal radiation these are then reradiated in all directions. But when some of these radiations come back to the scrape and lower atmosphere, it causes increase in the average surface temperature leading to global warming. Global warming CausesThe causes are many of which the main culprit is the increase in the greenhouse gases that is produced by burning fossil fuel and deforestation, 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. Min ing for coal and oil releases methane in the atmosphere. More ever the leakage from pictorial gas fields and landfills are additional source of methane. Excessive cutting down of the trees is another factor out causing global warming. When deforestation go throughs the efficiency by which carbon dioxide is stored and oxygen released by the green plants are decreased to a huge rate 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 large 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. frosting caps and glaciers reflect sunlight, bouncing high temperature sun -rays back into space away from th e Earth. When these icecaps are removed the undercoat gets warmer as the dark oceans absorb much thermal radiation from the sun. Some regions may be wet with rain and some areas will suffer drought due to global warming.The climatic changes happen due to global warming. Seasonal changes are unpredictable unexpected thunderstorms might result as mentioned earlier. The burning of wood (should be reduced to a greater extent) releases oxidizable carbon to the atmosphere whose charge in greater amount causes the elevation of temperature. There is strong evidence that emissions of chlorofluorocarbons (CFCs) were the major cause of the recent aberrant 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.
