Global Warming Essay Example | Topics and Well Written Essays - 500 words - 9

Global Warming - Essay Example urning of fossil fuels for instance coal, oil and natural gases contribute massively to this predicament .40% of United States carbon emission comes from coal burning power plants. More consumer products and cars for transportation are in production following the high population growth rate. This reflects negatively to global warming as more fossil fuels are used in the manufacturing and processing of these products. Cutting down forests to burn charcoal together with the former contributes to accumulation of carbon air in the atmosphere. The carbon air on amassing in the atmosphere forms a cover and restricts heat into the atmosphere. Much of the infrared radiation rising from the surface is absorbed by carbon in the air (Weart, 2008). This results to global warming. Besides this, the level of methane in the earth’s atmosphere also determines the global warming level in the atmosphere. Agricultural activities for instance decomposition of products to make manure, produces a l ot of methane gas. The number of livestock in the planet is also a matter to be troubled about when global warming is concerned. Herbivorous animals produce methane during digestion. These methane ,gases add up to the atmosphere and like carbon it also forms, a blanket in the atmosphere .The only way to curb this is if humans embrace the usage of environmental friendly fuels and reduce the amount of methane in the air. For instance, governments could promote improvements in efficiency in commercial lighting or they could promote the disastrous consumption of fossil fuels (Weart, 2008). Global warming poses harsh effects to humankind. The increase in temperatures in the atmosphere translates to poor rainfall in the planet. Thus, the temperature of the earth is at high level due to carbon accumulations (Weart, 2008).This challenges the agricultural sector, as the productions would not be enough to feed the ever-growing population across the globe. This increase in temperature in the earth

Next Generation Air Transportation System (NextGen) Term Paper

Next Generation Air Transportation System (NextGen) - Term Paper Example However, each improvement in the aviation industry has got a ripple effect that brings change all through the industry (Salas and Maurino, 2010). The demands for air travel have continued to grow, resulting to unprecedented growth within the industry. Growth in the aviation industry has resulted to an expanded workforce that has put pressure on aviation companies to reduce training period and quickly train qualified pilots (Salas and Maurino, 2010). At the same time, technological advancement is helping in implementation of highly complex, computerized systems that change the manner pilots and other personnel relate with other aircrafts. Similarly, there have been calls for broad improvements in traffic control system putting more pressure on industry professionals and researchers. All these influences, thus, have had a great impact on the industry and on the human factors. This present paper discusses the impact of NextGen will have on the human factors in the aviation industry. Nex tGen technology Despite program by Next Generation Air Traffic System (NextGen) being merely one of the many vehicles of transformation in aviation industry, presently, it stands for the most remarkable call for transformation in the aviation industry. ... Through the use of this new technology, the NextGen technology is bound to considerably improve service provision. For instance, projections by NextGen estimate that there is the need to reduce clogging in the air transports system of the US (FAA, 2007) NextGen has availed data equipment that has the ability to tap weather sources all over the airspace. This data has also enabled to provide accurate information on what lies ahead for any particular flight. This ability is also remarkably since aircrafts can access timely information from all dimensions (Salas and Maurino, 2010). The human factor through NextGen has totally overhauled earlier and outdated ways used by airspace bodies. This has significantly changed aviation sector since National Airspace System (NAS) of the US has managed to install better traffic loads. Moreover, it has also helped to project better means by reducing gridlock as well as maintaining safety in the aviation department. Essentials and Benefits Fundamenta l measures and improvements that NextGen has applied to refurbish human factor in the aviation sector include the inception of System Wide Information Management, Automatic dependent surveillance-broadcast, Next Generation Data Communications, Next NAS voice switch and Generation Enabled Weather. Through the use of, Automatic dependent surveillance-broadcast (ADS-B), NextGen (GPS) satellite signals offer efficient information to air controllers and pilots. Such information is much accurate and has increased aircraft safety through safe navigation in the sky. Besides, ground safety for airplanes has tremendously improved. In addition, NextGen has improved the human factor by fixing airplanes with special transceivers known as
