Climate Change EssayToday we terminate not question the naturalism of the climate alter because the evidences of its effects to nature argon already manifesting. The melting of the ice in north pole the hurricanes this past years the recurring drouth extreme weather permutes the rising of sea levels and, the strong typhoons are precisely a few of these evidences. thus far if we continue to ignore the threats associated with climate change, we can not deny nor alter the fact that its really happening. Despite the global buzz about climate change and its consequences, many individuals are still insensible of this phenomenon.So what then is climate change? How does it affect the planet we are living in? What can we do to alleviate this problem? Giving exonerated to these aforementioned questions is the aim of this part of my paper. The climate of the earth is continuously changing but these changes are minimal and are often due to natural etiologies. However, late the acti vities of mankind have brought about rigorous alterations in the earths climate. The recognition of these alterations of the earths climate led to the establishment of the climate change phenomenon.Today, the term climate change is employ to refer to the hoi polloiive modifications of the earths climate due to human activities. Climate change is the alteration in the normal pattern of the weather of an area over a period of time. This phenomenon is the manifestation of the irregular deviations from the usual climate inside the atmosphere of the Earth as well as its effects on the other components of this planet like the ice caps. The period of time involved in climate change can vary from a few years to millions of years (GreenFacts).Climate change is brought about by the amplified closeness of greenhouse gases like light speed dioxide (carbonic acid gas), nitrous oxide (N2O), and methane (CH4) in the atmosphere. CO2 is the greenhouse gas that is abundantly released into the e arths atmosphere. The luxuriously levels of greenhouse gases in the atmosphere prevent the normal mechanism of solar capability retention in the earths atmosphere as well as its reflection back to the space (outside earths atmosphere). In short, these so called greenhouse gases causes heat from the sun (solar energy) to be trapped within the earths atmosphere increase the normal temperature of the earth (GreenFacts).The greenhouse gases that are solid factors in the occurrence of the climate change phenomenon are emissions of human activities like fogy give the axe intent for energy purposes forests burn-offs and, change in the usage of land. The burning of fossil fuels is the primary reason for the presence of extensively high carbon dioxide levels in the earths atmosphere. Prior to the start of human utilization of fossil fuels the carbon dioxide concentration in the atmosphere was 280 parts per million (ppm). However, at present the CO2 concentration is raised to 390 ppm.Eac h year the CO2 concentration in the atmosphere increases by 1-2 ppm (GreenFacts). The consequences of climate change include the following increasing seawater levels melting of snow and ice in the mountains and polar regions increasing occurrences of heat waves drought changes in the wind patterns ocean salinity escalating intensity of tropical cyclones and, heavy precipitation. The climate change has enormous impact on the lives of mankind and animals the infrastructures and, the environment.The occupation of food is highly affected by climate change and can cause intensive hunger in many of the worlds population if not alleviated. Various eco organisations have been destroyed such as coral reefs due to warming of the seawater mangroves affected by drought or soil erosion and, plant and animal species lost due to forest fires. The occurrence of more disease epidemics and malnutrition are likely if extensive action is delayed. In order to stop climate change, the greenhouse gas em issions should be decreased to significant levels if not eradicated.In line with this goal, various countries have instituted policies regarding the lowering greenhouse gases release into the atmosphere. There are policies that were agreed upon and adapted by various countries but the individual countries around the world showed varied efforts in handling this problem. II. potentiality policies that can address climate change There are many potential policies that can be instituted to alleviate the harmful effects of climate change and in this paper three policies will be discussed.These policies are point force biofuels utilization and, carbon capture from coal power plants. Transportation efficiency is a significant insurance to alleviate the climate change dilemma. This is because the transportation sector (which includes passenger cars, aviation, rail road transport vehicles, and navigation) mainly utilize rock oil product fuels that is a considerable source of carbon dioxid e emission. Transportation efficiency policy focuses on increasing the diversity of fuels utilized and upholding the effectiveness of the transport systems.This policy can reduce the CO2 emission through the following strategies promoting the usage of fuel efficient vehicles lowering the road vehicle jamming promotion of mass transit systems and, advancing the efficiency of existing vehicles (Barry et. Al. , 2008). The less(prenominal)ening of road vehicle jamming will have a significant impact on the CO2 emission reduction because vehicles stuck in traffic jams continuously combusts fuel and release CO2 in the atmosphere. Thus, smooth road travels mean deduction in the fuel utilization and also decrease in the emission of CO2.Another aspect that will be promoted in the transportation efficiency policy is the passengers greater usage of light rail transport. Light rail transport systems utilize other forms of energy producing mechanism in their operations which means less fuel combu stion and less CO2 emission. Since the transportation sector is among the primary emitters of CO2 in the atmosphere The term biofuel refers to renewable energy sources that are produced from biomass (crops by design planted for biofuels production or plant materials from agricultural and industry wastes).The usage of biofuel as source of energy gained popularity because of its renewable nature. It is widely known as a solution to the diminishing fossil fuel supply. Recently though biofuel is considered as potential solution to the reduction of CO2 emission in relation to the backup man of climate change. Thus, biofuels utilization policy does not only benefit the economy but most significantly it will benefit the environment. Biofuels usage aides in the lowering of CO2 in the atmosphere through replacing the fossil fuels as energy sources and absorption of CO2 present in the atmosphere.The latter occurs when crops are purposely planted to be used as biofuel materials. Plants absor b atmospheric CO2 for their growth. Thus planting biofuel crops means absorption and reduction of atmospheric CO2. Also, the production of biofuels from biomass does not produce significant amounts of CO2 (U. S. Department of Energy, 1999). The various roles that biofuels can play in the reduction of CO2 in the atmosphere verify the significance of biofuels policy in combating climate change.The coal power plants are also among the significant emitters of CO2 in the atmosphere. In United States alone, coal power plants pass to 85 percent of the greenhouse gases released by the power sector (Geman et. al. ). Despite the high CO2 emission of coal power plants, it is still continuously used as the primary source of energy in countries like U. S. because no alternative energy source has yet been able to surpass its economic benefits. The high CO2 emission of coal power plants can be solved by the carrying out of carbon capture policy.The installation of carbon capture system in coal power plants has been done in various countries. Among the pioneers of carbon capture system usage is the Elsam coal-fired power plant in Esbjerg, Denmark. The usage of carbon capture system among coal power plants can greatly reduce the carbon emission into the atmosphere without compromising the price of the electricity. III. The best policy resource to address climate change In my point of view, the best policy option is transportation efficiency.This is because the realization of this policys goals will not only help in the reduction of carbon dioxide release in the atmosphere but will also ease the travel experience of passengers reduce the transportation costs and, safeguard public health. The transportation sector is the third major emitter of CO2 in the atmosphere. Thus, ensuring that the transport sector emits significantly reduced amounts of CO2 is equivalent to decreasing a huge percentage of the total CO2 emission.The transportation efficiency policy though has a high complex nature because it encompasses infrastructures like road and light rail stations vehicle manufacturing traffic regulations and, fuel policies like alternative fuels. The complexity of these strategies needed for the transportation efficiency policy implementation though is worth all the effort because of this policys vast benefits. The dilemma on climate change though can not be alleviated by the implementation of only one policy.The complexity of this problem necessitates the execution of various policies and strategies as well as cooperation of all the nations around the world. Even though some countries already practice methodologies to combat this problem, if other countries will not reduce their greenhouse gases emissions the problem will continue to get worse. A unified action the nations of the world is needed to significantly resolve climate change.Works CitedBarry, J. and Allen, A. M.
