The Alarming Increase In Earths Temperature Environmental Sciences Essay
The Alarming append In Earths Temperature Environmental Sciences EssayThese days every one agrees upon the fact that there is more or lessthing strange and worrying adventure to the melodic phrase. Climate adjustment and world- spacious warming are issues which are concerned with every soulfulness living around the earth. Almost each and every individual is affected by the change in climatic conditions and alarming increase in grounds temperature..Literature reviewDefinitionsClimate change refers to a change in earths weather which includes the change in spherical temperature, wind patterns, and rainwater. The jet-propelled plane house transaction is considered a major reason for humor change. The spurt house effect is a phenomenon which describes the earth as a green house made up of glass which totallyows light of the sun to enter but then traps it, preventing it from escaping. A green house is a structure made up of glass used for commercial purposes such as produc ing off season vegetables, plants and flowers. The glass walls traps the shaft of light in it and does not allow them to escape. This makes the green house warmer which provides optimum temperature for plants even during winters. The same process occurs in the earths atmospheric layer. The green house gases acts identical the roof of a green house. During day time the earths surface absorbs sunlight and gets warmer, at night the earths surface reradiates the ignite blanket into the atmosphere but some of the heat still remains in the earths system delinquent to the absorption by green house gases.The earth depicts such a behavior delinquent to the presence of green house gases (GHG) in the earths atmospheric layer. GHGs include carbon paper dioxide, water vapors, methane, oxides of sulfur and atomic number 7. How ever the contrary is the concept of global dimming which occurs due to change in the characteristics of clouds due to pollutant particles. As the clouds become more reflecting most of the heat from the sun is then reflected back which causes a cooling effectThe DebateThe mood debate has become the hottest debate during the last days. The debate between the experts whether to regulate harmful emissions or not has given rise to regulatory uncertainty which medical intern has even worsen the situation.The industries involved in mining activities, power plants, and automobile are putting a lot of s gimmick on the environment. Every year they are adding up millions of tons of sulfur dioxide, nitrogen dioxide, carbon dioxide and heavy metals in the environment. With proper control regulations on these plants climate change can be significantly decreased. Due to uneven regulations and no tribal emission limits the process of installation of pollution controls power plants are slowing down. In this regard a few(prenominal) environmentalists in order to achieve their long term climate policy goals are actually ignoring short-term health and envir onmental benefits.When it comes to pollution controls, they cost a lot to install and thus their feasibility can tho be justified when they are applied only to coal fired power plants so that the costs could be recovered due to their larger operations.The specifics of the climate change regulations are not known and therefore the utilities are unable to decide when these pollution controls should be installed. Unfortunately there are no add-on control technologies which could prove helpful in removing the green house gases from power plant emissions. just the emissions of SOx and NOx can be controlled by add-on pollution control technologies. The SOx and NOx are considered more injurious to health than the green house gases. all the same the global temperature increase is an trouble worthy issue which is mainly caused by green house gases.The issue of climate change and global warming has gained geopolitical importance in the recent years. It refers to an overall increase in ave rage global temperature. Anthropogenic processes and natural events are simultaneously contributing towards global warming.The green house effect which is caused by increasing concentration of Green house gases such as Carbon Dioxide, CFCs, water vapors, oxides of nitrogen and methane mainly is responsible for retaining heat in the atmosphere. almost of the radiations reaching the earths thermal infrared range are absorbed by the Green house gases and rest are reradiated or emitted back in the environment. In short Green house gases prevent the escape of heat from the earths environment rather they are reflected back essenceing in an increase in global temperature.The key indicators representing climate change published by NASA (National aeronautics and space administration) are as under.1. Rise in sea level2. Increase in carbon dioxide concentration3. Declining Arctic sea ice4. Shrinking ice sheets5. Global temperature rise6. Warming oceans7. Glacial retreat8. Ocean acidification Some Opposing view in climate change debateA number of scientists oppose the mainstream, scientific assessment of global warming. They are of the view that set-back the idea of global warming does not exist and if there is such thing then it is not caused by human activities rather it is happening as a part of natural processes.The two main scientific claims of the IPCC are the claim that the clod is warming and Increases in carbon dioxide emissions are responsible. Evidence for both of these claims is fatally flawed (Gray, 2008)Dr Gray further clarifies his point of view by addressing the graphs which shows that the mean annual temperature of the globe is increasing. He denies that the practice of measuring the average global temperature of any part of the world has ever been done so how could we make it a reference point.Experts of the United Nations in regular reports publish data utter to show that the earth is approaching a catastrophic global warming, caused by increasing e missions of carbon dioxide to the atmosphere. However, observations of the sun show that as for the increase in temperature, carbon dioxide is not guilty and as for what lies ahead in the future decades, it is not catastrophic warming, but a global, and very prolonged, temperature drop. (Abdussamatov, 2009)Habibullo is of the believe that the global warming is due to a gradual increase in the activities of the sun and carbon dioxide should not be considered as an agent for causing global warming.The global scenario of peace, development and successfulness is changing. Furthermore climate change can result in depletion of food and water supplies it can give rise to conflicts and even destabilize societies and authorities.The recent climate change trend is more significant for us because it is anticipated mostly by human activities. The increased levels of green house gases are qualification the earth warmer. Carbon dioxide and other gases are known for their heat-trapping nature. Instead of escaping into space the infrared radiations from the sun are trapped by green house gases in the result they remain in earths system.Burning of fossil fuels by humans causes carbon dioxide to release in the environment. Furthermore methane is produced from agriculture activities in rice fields. Live simple eye also contributes to it as fermentation of manure generated methane. CFCs are generated from refrigerators and aerosols.The global warming and melting of land ice causes thermal expansion of sea water.The glaciers around the globe are melting causing an increase in the global sea level. The increase in sea level depart accelerate in the upcoming years because of increase in global warming.Two weeks ago, I visited Arctic I saw the remains of a glacier that just a few years ago was a majestic mass of ice. The Arctic could be virtually ice free-by 2030 (Ban KI-moon)Global warming is not only affecting the environment, it has direct unfavourable effects on humans, an imals and plants. From Natural habitats of softheaded life to mangrove forests which are breeding ground of fishes all are getting affected by it. The oxides of nitrogen and sulfur which are present in the atmospheric layers of gases react with rain water and produce acid rain. The acid rain is corrosive and it not only contaminates water bodies but it also destroys marble buildings and sculptures.According to NASA Global climate change causes a shift in animal and plant ranges and also causes tress to flower sooner. All the predictions which were made by the scientists regarding climate change are proving true. The future effect of climate change includes more frequent wildfires, longer periods of drouth in some regions, and an increase in number, duration and intensity of tropical storms.Some of the future trends adapted from inter governmental panel on climate change (IPCC) are as underContraction of snow cover areas, increased thaw in permafrost regions, decrease in sea ice con tent.increase frequency of hot extremes, heat waves and heavy precipitation.Increase in tropical cyclone intensity.Precipitation increases in high altitudes.Precipitation decreases in subtropical land regions. fall water resources in many semi-arid areas.DiscussionLack of regulations, regulatory uncertainty and lack of interest regarding environmental issues amongst the inhabitants specially belonging to under developing countries is making this issue even worsen. The economic crush which is prevailing throughout the world has negatively affected the priority of this important issue , where everyone is struggling for making their carbohydrate and butter and to practiced fill the basic necessities of life. In this type of situation people are not ready to use their assets, efforts on addressing this issue.Experts on the other hand are aware of the importance of the issue. They are observing the ice melting on the glaciers with a rapid pace. The sea level around the globe is rising increasing the risks of some major floods. It is expected that sea levels will rise by over 40 cm by the 2080s .Infect though with a slow pace the earths landscape as a whole is changing. The dry part (land) is continuously shrinking disturbing the natural habitats of a number of wild lifes species. With the passage of time wildlife animals undergoes evolution in order to make them selves compatible with the outside environment. The evolution leads to the concept of the survival of the fittest. The one which lacks behind the race collapse to face extinction.Human population is also affected by the climate change in the very same way .The year 1998 was the warmest year globally since data collection began in 1861.In the year 2003 some 30,000 people lost their lifes due to a sudden heat wave , making this phenomenon extremely attention worthy for the scientists. The average temperature of the UK may rise by 2-3.5 degree by 2080s.If we see the situation in our own country the demand o f electricity peculiarly in summers has raisin a lot. As the summers are getting longer and more severe than previous years living without a fan or an air-conditioner is change state a big deal.This situation prevails through the world as the summers are getting longer and winters are shrinking. In this manner the rainfall frequency will also change it is expected that in up coming years winters will become wetter and summers drier. In south east summer rainfall may decline by 50 by the 2080s.Some worst impacts of climate change includes declining winter storms shifted towards north, increase in precipitation intensity, soaring of temperature, wide spread mortality of vegetation, and increases in the frequency of large wild fires.But wait now the point is who actually is responsible for the outbreak of this new phenomenon. It is no doubt the anthropogenic activities of the humans which are destroying the environment.Green house gases include carbon dioxide, water vapors, methane a nd CFCs. Sources of CFCs are aerosols, refrigerators, and air-conditioners. These human activities are releasing harmful gases in the atmosphere which thickens the atmospheric layer. This thickened layer prevents the escape of heat from earths environment resulting an increase in global temperature.There are concerns that Carbon dioxide emission has increase to alarming levels but only few of the climate analysts fees that it is a bit early to draw final conclusions on this phenomenon. The carbon dioxide concentration in the atmosphere is increasing with a rapid pace. It is considered as one of the most important green house gas.CO2 is released due to the combustion of fossil fuels, natural factors and volcanic eruption. It room the free energy we consume is becoming an agent to destroy our environment. It can be administered by adopting renewable energy sources rather than fossil fuels. The agro fuels are clean and green and because of photosynthesis they help reducing carbon di oxide from the atmosphere.(The global monitoring division of NOAA/earth system research laboratory)The above graph shows the rising trend in global CO2 concentration from years 2006 to 2010.Some experts also believe that the earths ability to absorb the gases is reducing resulting in acceleration of green house effect.Conclusion orbiter earth belongs to all living in it. Its every ones responsibility to protect it from climate change. On the whole the anthropogenic activities are responsible for global warming. some(prenominal) steps should be taken in this regard. Promoting public transport and adopting efficient and environment friendly transport could be the first step. This reduces the number of cars on the passageway which intern reduces carbon dioxide emissions.Arboriculture specially when done on larger scale reduces the impact of global warming. In most of the countries this is done under government plan simultaneously people should also showing concern and are planting tr ees on their own.Preferring energy efficient products could be a vital step. The energy savers bulbs are on the top of the list. As these products consumes less energy so the overall demand for energy could be reduced this could be help full in decreasing the dependence on fossil fuels.Most of the experts find it too early to say that new trends are setting up. But all of them agree upon the fact that this phenomenon should be addressed on urgent basis.
