The Alarming Increase In Earths Temperature Environmental Sciences Essay

The dread Increase In Earths Temperature Environmental Sciences Es gradeThese days every iodine agrees upon the fact that there is something strange and worrying happening to the atmosphere. Climate modify and ground(a) take fireing are have intercourses which are concerned with every several(prenominal) living around the musket ball. Almost each and every individual is impact by the de social occasion in climatic conditions and alarming adjoin in humankinds temperature..Literature reviewDefinitionsClimate turn refers to a variety in earths weather which includes the qualifying in world(a) temperature, wind patterns, and rainfall. The commonalty hall centre is considered a major reason for humour change. The grand abode effect is a phenomenon which describes the earth as a unripe abode agnize up of glass which allows light of the sunlight to enter hardly then traps it, preventing it from escaping. A green house is a structure made up of glass used for comm ercial purposes such as producing bump off season vegetables, plants and flowers. The glass walls traps the radiation in it and does not allow them to escape cock. This makes the green house warmer which provides optimum temperature for plants even during overwinters. The same process occurs in the earths atmospheric layer. The green house gases acts like the roof of a green house. During day time the earths lift absorbs sunlight and gets warmer, at night the earths surface reradiates the change fundament into the atmosphere but some of the heat whitewash remains in the earths system imputable to the absorption by green house gases.The earth depicts such a behavior due to the forepart of green house gases (GHG) in the earths atmospheric layer. GHGs include coulomb dioxide, piddle vapors, methane, oxides of sulphur and nitrogen. How ever the contrary is the thought of planetary dimming which occurs due to change in the characteristics of clouds due to pollutant parti cles. As the clouds become more reflecting most of the heat from the sun is then reflected back which causes a cooling effectThe contestThe modality debate has become the hottest debate during the last years. The debate amongst the experts whether to regulate harmful firing offs or not has break dancen rise to regulatory uncertainty which intern has even worsen the space.The industries involved in mining activities, prop mavinnt plants, and automobile are putting a pass around of dialect on the environs. Every year they are adding up millions of tons of sec dioxide, nitrogen dioxide, ascorbic acid dioxide and heavy metals in the environment. With proper control regulations on these plants clime change can be significantly drop-offd. Due to lumpy regulations and no tribal emission limits the process of installation of pollution controls function plants are slowing down. In this regard few environmentalists in tell apart to achieve their long term climate policy goa ls are very ignoring short-term health and environmental benefits.When it comes to pollution controls, they cost a lot to install and thus their feasibility can scarcely be reassert 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 k straight offn and therefore the utilities are unable to settle when these pollution controls should be installed. Unfortunately there are no appurtenance control technologies which could prove helpful in removing the green house gases from power plant emissions. But the emissions of SOx and NOx can be controlled by tack pollution control technologies. The SOx and NOx are considered more injurious to health than the green house gases. However the global temperature annex is an fear suitable issue which is mainly caused by green house gases.The issue of climate change and global melting has gained geopolitical importanc e in the fresh years. It refers to an overall increase in average global temperature. Anthropogenic processes and inborn events are simultaneously contributing towards global warming.The green house effect which is caused by increasing tautness of Green house gases such as degree Celsius Dioxide, CFCs, pissing vapors, oxides of nitrogen and methane mainly is responsible for retaining heat in the atmosphere. Some of the radiations reaching the earths thermal infrared range are indifferent 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 quite they are reflected back publicationing 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 direct2. Increase in blow dioxide density3. Declining Arctic sea ice4. Shrinking ice sheets5. Global t emperature rise6. Warming oceans7. rimy retreat8. Ocean acidificationSome Opposing view in climate change debateA number of scientists oppose the mainstream, scientific assessment of global warming. They are of the view that first the idea of global warming does not exist and if there is such thing then it is not caused by charitable activities rather it is happening as a part of natural processes.The two main scientific claims of the IPCC are the claim that the globe 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 tight 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 through so how could we make it a reference point.Experts of the United Nations in regular reports publish info said to show that the earth is approaching a catastrophic global warming, caused by increasing emissions 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 upcoming decades, it is not catastrophic warming, but a global, and very prolonged, temperature drop. (Abdussamatov, 2009)Habibullo is of the reckon 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 factor for cause global warming.The global scenario of peace, development and prosperity 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 government.The recent climate change course of instruction is more significant for us because it is anticipated mostly by human activities. The increased levels of green house gases are making the eart h 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 fogy fuels by humans causes carbon dioxide to release in the environment. Furthermore methane is produced from agriculture activities in rice fields. love stock besides 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 entrust 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 direful mass of ice. The Arctic could be virtually ice free-by 2030 (Ban KI-moon)Global warming is not o nly affecting the environment, it has direct adverse effects on humans, animals and plants. From Natural habitats of wild life to mangrove forests which are breeding grounds 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 patronise wildfires, longish periods of drought in some regions, and an increase in number, epoch and intensity of tropical storms.Some of the future trends adapted from inter political panel on climate change (IPCC) are as underContraction of snow cove r areas, increased thaw in permafrost regions, decrease in sea ice content.Increased frequency of hot extremes, heat waves and heavy precipitation.Increase in tropical cyclone intensity.Precipitation increases in highschool altitudes.Precipitation decreases in subtropical land regions.Decreased water resources in many semi-arid areas.DiscussionLack of regulations, regulatory uncertainty and lack of divert 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 wampumpeag and butter and to full 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 sight 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 anticipate 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 strike the natural habitats of a number of wild lifes species. With the passage of time wildlife animals undergoes organic 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 have to face extinction. homo 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 of electricity especially in summers has raisin a lot. As the summers are getting longer and more severe than previous years living without a winnow or an air-conditioner is becoming a big deal.This situation prevails through the world as the summers are getting longer and winters are shrinking. In this trend 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 fatality rate 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 enquiry the anthropogenic activities of the humans which are destroying the environment.Green house gases include carbon dioxide, water vapors, methane and 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 raised 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 means the 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 cl ean and green and because of photosynthesis they help bring down carbon dioxide 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.ConclusionPlanet 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 effective and environment friendly transport could be the first step. This reduces the number of cars on the road 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 si multaneously people should also masking concern and are planting trees 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 dependency 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.
