Climate Change Essay immediately we cig bet not question the realism of the mood deepen because the evidences of its effects to nature are already manifesting. The melting of the ice in north pole the hurri potes this past years the recurring drought radical weather changes the rising of sea levels and, the strong typhoons are only a few of these evidences. Even if we sojourn to ignore the threats associated with humor change, we can not deny nor alter the fact that its really happening. in spite of the global buzz about modality change and its consequences, many individuals are still unaware of this phenomenon.So what then is mood change? How does it affect the satellite we are living in? What can we do to compose this problem? Giving light to these aforementioned questions is the aim of this part of my paper. The climate of the earth is forever changing but these changes are minimal and are often due(p) to natural etiologies. However, recently the activities of glo be 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 used to refer to the large modifications of the earths climate due to human activities. Climate change is the alteration in the formula 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 intumesce as its effects on the different components of this planet like the ice caps. The period of time involved in climate change can deepen from a few years to millions of years (GreenFacts).Climate change is brought about by the amplified concentration of greenhouse gases like deoxycytidine monophosphate dioxide (carbonic acid gas), nitrous oxide (N2O), and methane (CH4) in the atmosphere. CO2 is the greenhouse gas that is abundantly released in to the earths atmosphere. The soaring levels of greenhouse gases in the atmosphere prevent the normal implement of solar pushing memory board in the earths atmosphere as well as its reflection back to the station (outside earths atmosphere). In short, these so called greenhouse gases causes vex from the sun (solar energy) to be trapped inside the earths atmosphere increasing the normal temperature of the earth (GreenFacts).The greenhouse gases that are significant factors in the occurrence of the climate change phenomenon are electric arcs of human activities like fossil fuel burning 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 elevat ed to 390 ppm.Each year the CO2 concentration in the atmosphere increases by 1-2 ppm (GreenFacts). The consequences of climate change imply the following increasing saltwater 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 humans and animals the infrastructures and, the environment.The production of food is highly affected by climate change and can cause intensive hunger in many of the worlds universe of discourse if not palliate. Various ecosystems 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 dress to stop climate change, t he greenhouse gas emissions should be decreased to significant levels if not eradicated.In pipeline with this goal, motley 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. Potential policies that can reference book 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 give be discussed.These policies are transportation efficiency biofuels utilization and, carbon capture from coal role plants. transferral efficiency is a significant form _or_ system of government to alleviate the climate change dilemma. This is because the transportation heavens (which includes passenger cars, aviation, rail thoroughfare transport vehicles, and navigation) mainly util ize petroleum product fuels that is a considerable source of carbon dioxide emission. deportation 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 way vehicle jamming promotion of mass transit systems and, advancing the efficiency of existing vehicles (Barry et. Al. , 2008). The lessening of passage 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 alley travels mean deduction in the fuel utilization and also decrease in the emission of CO2. other aspect that will be promoted in the transportation efficiency policy is the passengers great usage of light rail transport. Light rail transport systems utilize other forms of energy pro ducing mechanism in their operations which delegacy less fuel combustion and less CO2 emission. Since the transportation welkin is among the primary emitters of CO2 in the atmosphere The term biofuel refers to renewable energy sources that are produced from biomass (crops purposely ingrained 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 alleviation 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 substitution the fossil fuels as energy sources and absorption of CO2 present in the atmosphere.The latter occurs whe n crops are purposely planted to be used as biofuel materials. Plants absorb 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 contribute to 85 percent of the greenhouse gases released by the power sphere (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 to date been able to surpass its economic benefits. The high CO2 emission of coal power plants can be solved by the imple mentation 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 option 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 be 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 roadway and light rail stations vehicle manufacturing traffic regulations and, fuel policies like alternative fuels. The complexity of these strategies needful 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 incorporate action the nations of the world is needed to significantly resolve climate change.Works CitedBarry, J. and Allen, A. M.
