Possible Effects Of Global Warming Essay

If the world(a) temperature swells by another 7 degrees, wherefore it whitethorn result in feeding of north-polar ice which may result in about a 3 to 4 fundament increase in sea levels. If such(prenominal) thing happens, then much low lying areas in the cosmos especially Bangladesh, Netherlands, Guam, Indonesia, Maldives and Sri Lanka could be engulfed by sea piddles. Increase in global temperature may trigger the bedcover of dreadful diseases kindred Malaria, Virus fever, dengue fever and other sub-tropical diseases. of all time increasing temperature may upset weather patterns all over the macrocosm , causing starvation due to drought in prime pabulum producing regions namely South Asia , sub-Saharan Africa and tropical Latin America. Due to unexampled increase in temperature, the whole gamut of species of animals and comprises could be wiped out. 7. MAJOR PLAYERS OF GLOBAL melting U. S. A is not only a foremost economy of the world scarcely also the largest consume r of dodo fuels and naturally, it is the biggest producer of greenhoexercising go down onses, comprising of more than 20% of the worlds speed of light dioxide emission which is about 5 trillion metric tons.Being the most industrialized economy, U. S. A is heavily depending on coal, oil and natural gas for its brawniness needs and hence U. S. A government is rather reluctant to initiate any appropriate step to limit the glasshouse gas emissions and charges that Arrhenius theory is only a myth. U. S. A is averse to initiate any immediate action restraining the use of fogy fuels or to limit such use as they fear it would acquire long term effect on its economy.According to orbicular clime Change Coalition, an industry group which is vehemently opposing prescribing mandatory limits on nursery gas emissions as it would result in the ruining of economy. notwithstanding , a study pursued by the coalition group forecasts that if U. S. A pursues some measures on restricting its gre enhouse gas emission , then it would result about a 3% decline in U. S gross domestic product by 2010, resulting in a go of 25% in the growth rate of Americans archetype of living.

The Kyoto communications protocol has prescribed mandating limits on carbon emissions which took effect in 2005 nearly after eight grades of it was faced. Regrettably, U. S. A, the worlds cabbage carbon unleashter has yet to ratify the Kyoto Protocol. nearly Energy companies and economists dupe proposed to introduce taxing carbon as an enticement to tempt both the industries and consumers to use low carbon emitting fuels.Gases same(p) Chlorofluorocarbons CFC are man do ones and this gas was used as propellants in aerosol containers, as refrigerants and also wor ld used as a solvent in the catch up with of data processor chip. It has been discovered that CFC were mutilating the stratospheric ozone layer thereby permitting majority of the suns destructive ultraviolet radiation to reach the humankind race. The World CFC manufacturers squander agreed to phase out their production of CFC by sign 1987 Montreal Protocol on Substances that deplete the Ozone layer.It is to be observed that the man do gasses homogeneous CFC is damaging the Ozone layer only actually diminished and the major culprit is the carbon dioxide. Further felling the trees also contribute the level of CO2 high in the atmosphere as green trees helps to revoke the gasses from the atmosphere or to maintain equilibrium. During the May 2005, peeled Zealand had introduced carbon taxes mainly to dissuade excessive use of carbon oriented fuels. Thus, New Zealand had impose about 6% to home electricity consumption and 9% for disdain dynamism salute.By 2012, all signator ies to Kyoto Protocol should deoxidize their GHG emissions to less than 5% which is below 1990 levels. Likewise, The European Union had introduced a regional cap and-trade insurance policy to make it convenient for high emitting EU countries to oblige. 9. ADVANTAGES OF LIMITING THE EMISSION Some U. S industries, though initially opposed to prescribe caps on emission, later(prenominal) considered that the stricter policy as not only environmentally essential but also potentially advantageous to economy since it willing push for the c erstwhilept of new technologies.Further, Title IV of the 1992 Clean Air Act demanded industries and utilities to smear their sulfur dioxide emissions which are released by burning coal. Many companies who have exceeded their sucker sold their excess allowances to some companies that fall short of complying the above provision. Thus, a market in sulfur dioxide allowances materialized. The trading of these excess allowances is being conducted on th e Chicago Board of Trading along with the markets for agricultural products and pork abdominal cavity futures. 10. THE METHODOLOGY OF GREEN dramatics WARMING EARTHS SURFACEThe greenhouse phenomenon is nothing about carbon dioxide and other greenhouse gases discharged into the Earths atmosphere will trap solar heat and such trapping will warm the states surface and earths lower atmosphere. The greenhouse gas emission effect has been explained in the following diagram FIG 2 EFFECT OF GREEN HOUSE GAS EMISSION Source National Aeronautics and Space Administration. 11. CRITICS rock AGAINST FINDINGS Some critics corresponding Sallie Baliunas who is Harvard Universitys astrophysics solicit that in the past ampere-second alone, there was an increase of just 0.5 degree Celsius and not more than a 10 to 20 % of a degree could have been caused by human-made greenhouse gases. According to Baliunas, the 0. 5 to 1. 5 degree Celsius melting foretold by the computer simulations overstates the greenhouse effect created by the equivalent 50% buildup of carbon dioxide. Some critics argue that IPCC disclosure that there is a perceptible human influence on global climate tosses the finding itself into air. Some critics vehemently lament that sea-level surge divineions are embellished as the temperature in polar region would still remain below freezing.Some points out those supporters have projected an illusion that global heating plant would result in the counterpane of malaria and mosquito oriented diseases. Supporters of global warming have forgotten to take into compute the advanced technology for sale as on date like air-conditioning, mosquito repellents and mosquito coils and modern medicines have completely eradicated Malaria from the soil of U. S. A and substantially in other countries. Likewise, critics assailed a report forecasting that algal blooms amplified by warming waters would cause cholera was disparaged as unfounded one by the evidence.12. IPCCs FINDING S ON GLOBAL WARMING United Nations Intergovernmental Panel on Climate Change IPCC has made the following revelations about global warming ? at that place will be an increase of 15 to 90 centimeters in sea levels or by 6 inches to 3 feet by the year 2100. This mainly due to raising global warming which will melt polar ice sheets and the glaziers and there will be an expansion of water due to its getting warmed. ? Global warming will result in increase of extremely hotter days and there will be fall of cold days in general.? There will be drastic change in weather pattern causing havoc floods like Katrina and some provinces will be engulfed by famine or droughts. ? There will be an intensity of rainfall as scientists would not predict whether severe storms and tropical cyclones would transform the intensity and location. If the sea level increases from fractional foot to three feet level , then that would extensively flood the areas like parts of south Florida and southern Louisian a and would create an wide-ranging groundwork changes in cities like Texas , Dallas , S.C , Charleston and some extent New York City. Further, regional warming trend over the past five decades has made ice shelves along the coast of Antarctica to crumple. Some supporters of the global warming argue that people would be benefit from climate change. According to World Climate Report, warmer climate will pave the way for opening up Siberia and northern Canada suitable for agriculture production, increase the rainfall globally and minimize the perils of winter driving.According to World Climate Report magazine that global warming would usher more advantages and these advantage will overtake its disadvantages. see a warmer climate in poles, Siberia and in Netherlands. It would drastically reduce the push consumption on heating, reduced clothing expenses, transportation will be less problematic and overall death rates would be at a lower level. Plants absorb the carbon dioxide through their leaves, use up it in the process of photosynthesis and then emit oxygen. Thus, the oxygen released by plant is taken up by the animals for their existence.Thus, carbon dioxide released by animals is returned to atmosphere and once again taken up by the plants as well as by oceans that envelop the Earths surface. 13. FUTURE ACTIONS TO BE prosecute United States, China and India are the three countries which have to be complicated for the long-term reduction and these countries are not part of Kyotos Protocol first round. Since United States is not a signatory to the Kyotos Protocol, incisive emissions below 1990 level would be impossible to achieve. 14. ALTERNATE ENERGY rick energy is being employed in a large message in Germany and in a substantial way in countries like India, Denmark U. S, and Spain. As of today, wind energy is growing in a betting space due to technological advancement. It is to be observed that wind energy does not harm the environment and does not ge nerate any greenhouse gases or atmospheric emission. Wind energy is named as renewable energy as it is replenishable and depends upon the sun as it is a form of solar energy. Hence, as long as sun is there, wind energy can be harnessed without any limit.tidal energy is being harnessed to manufacture electricity also. A tidal power plant is in operation on the Rance River, an estuary of the English Channel in northwestern France since summer 1966. Tidal power plants will be most effective if the difference amidst high and low tides is enormous, as in Rance estuary, it is estimated that the difference is around 8. 5m or about 28 feet. Nuclear energy is a clean, competent and cost effective energy of the future. Some argue that though the nuclear energy is costly but it can be tolerated as it is a very efficient form of energy.For example, when set of uranium fuel rods is fitted in a nuclear reactor, it needs not to be replaced for many years. Further, uranium is available in plenty and its supplies are assured for many centuries ahead. As compared to fossil fuel based power plants , nuclear power plants does not emit toxic gasses in the atmosphere which ultimately responsible for global warming. It is to be remembered that a nuclear power plant does not pollute each the atmosphere or the water as compared to a coal-fired power plant.
