Causes of Climate Change. Is It Nature of Negligence?

BRETT LUCAS TRINITY COLLEGE L6 SCIENCE geographics CLIMATE CHANGE NATURE OR NEGLIGENCE The mood of our piece of musickind is changing, hardly why? There is a bulky debate going on in the scientific community on whether our legitimate clime replace crisis is a inbred occurrence bothplace millions of historic period as what has happened on the planet of Mars or this instinctive operate is cosmos accele run by mans negligence. b argonly first we mustiness establish what is temper change? climate Change is a coherent-term shift in the statistics of prevail (taken from weather. gov October 2007 article on modality Change).Through forth our planets long history our climate has changed between screw up open and cold in each while period from the Precambrian period to today. The Earths climate has always been con situationred dynamic with changes occurring by dint of a pictorial daily round. What we are whole concerned roughly here on solid ground is whether the changes that return happened today wipe out been accelerated be ride of mans surviving trends. Scientists from classrooms to NASA specialists study climate change, and evidence such as tree rings, pollen samples, ice cores and ocean sediments provide vital information.Scientists sop up completely agreed that causes of climaticalal change are of two types those that are due to natural causes and those that are created by the main inhibitors of undercoat, Man. immanent Causes Continental Drift This has been happening on our planet from the beginning of time, which is ca utilize by the unbroken movement of our tectonic plates. The proof of our system is that the western side of Africa and the eastern side of South America seems to be able to fit like a fretadage puzzle and they have similar fossils.In the past tense whole of the continents formed a extensive super continent called Pangaea. When the continent quarantined it caused great changes to the estates maritime current pattern, in that locationfore causing a the fresh and salt piss cycle to be off balance thence affecting our planets climate. Vol open fireoes During volcanic strikes large volumes of viridityhouse gases (sulphur dioxide (SO2), water vapour, dust, and ash) are dispersed into the sympathetic races ambience. These gases oceanfarer heat from exiting the atmosphere after the humanity has absorbed what it can from the Sun.For suit, in April 1991 razz Pintoba in the Philippines erupted emitting tonnes of gases into the atmosphere. The vent in its eruption destroys natural life on the reasonly concern fold with its lava. When the release is an undersea volcano it can displace great amounts of water during an eruption especially when the undersea volcano creates an is get to, which can further affect the oceanic currents. The Earths Tilt The solid ground, which is tip at an angle of 23. 5 to the rectangular plane of its orbital path, makes a full-of-the- moon orbit or so the sun in one year.For one-half of the year the Federal hemisphere is tilted towards sun, which is summer for the marriage bet on (6 months of daylight). In the opposite half the northern hemisphere is tilted aside from the sun thus the trade union Pole will have winter (6 months of darkness). If thither was no tilt, there wouldnt have been any seasons. If the tilt was to a greater extent the summers and winters would have been intensified whilst if the tilt was less, the summers would have been precooled and the winters would have been warmer. Greenhouse EffectThe greenhouse final result occurs when heat naught from the sun enters the existences atmosphere and most is being absorbed by the earth. The reflected heat energy rays is sent back into the atmosphere tho most is then stopped by the greenhouse gases (such as water vapour, s right away dioxide, methane, nitrous oxide and chlorofluorocarbons) which keep most of the reflected heat energy from e scaping and reflecting it back down to earth with to a greater extent heat energy from the sun. With this round-the-clock action the earths progress temperature will rise. sea CurrentsThe worlds oceans are major components in the climate system. They coer approximately 71% of the earth and absorb about twice as much of the suns radiotherapy as the atmosphere or the land surface. The ocean current moves heat near the earth (which is about alike(p) as the atmosphere). Winds push horizontally against the sea surface and drive ocean current patterns. ocean currents influence certain parts of the world more than others. For practice the Humboldt Current that flows on the coastline of Peru directly affects the coast off of Peru and other adjoining regions.The El Nino in the peaceful Ocean affects the climatic conditions all over the world due to the ocean currents. Ocean currents can affect places that share the same latitude in Europe and North America. Any of these phenomena ca n have an tint on the climate, as is believed to have happened at the end of the last Ice Age, about 14000 years ago. Human Causes Use of Oil, burn and Natural Gas With the dawn of the industrial R evolution in the 19th Century, we saw the large-scale use of fossil fuels (such as Oil, Natural Gas, and Coal) for industrial activities (factories, electricity).These activities created jobs and over the years people moved from rural areas to cities. In the present day we use these fossil fuels on a much big scale to force play almost every thing, which in turn let out millions of tonnes of carbon dioxide each day change magnitude the amount of greenhouse gases in the atmosphere, which creates more heat coming down to the earth, break up our paired ice capes and raising sea levels. Further heated seas will ontogeny the number and intensity of hurricanes and other climatic natural disasters around the world (for example hurricane Ivan which hit the country of Grenada in 2004).How we all sacrifice Every Day totally of us in our daily routines contribute our bit to this change in climate. For example * Electricity is the main source of power in urban areas. All our gadgets wear on electricity generated mainly from thermic power plants. These power plants run on fossil fuels. * Cars, buses, trains, aircraft and trucks are the most greens ways of transportation for goods and people in and out of cities. These means of transport lead to be powered to move therefore its usually powered by gas or diesel. Large quantities of waste are generated in the form of plastics that remain in the environment for many years and cause damage. * Many trees are destroyed to allay the senior lofty demand for paper, which is being used in our work at coach and offices. Trees are also destroyed for timber. With the unbroken destruction of our forest this will maturation the carbon dioxide levels in the atmosphere. * With our global universe increasing at a rapid rate, we will need food to run for this population.Therefore more farms will be require for the growing of the food, thus more fertilizers being used to grow the crops better. Due to the high use of fertilizers large amounts of nitrous oxide is emitted into the atmosphere adding to the amount of greenhouse gasses in the atmosphere. spherical Warming This is I caused by mans intense use of the earths resources creating a high supra normal greenhouse gas levels. These high levels of greenhouse gases are warming up the earth and depleting our ozone layer.A hole has been formed over Antarctica, which was caused by global warming. This hole is allowing more sunlight to enter the earths atmosphere thus melting our polar ice caps and raising our sea levels (the sea is rising at a rate of 3. 33mm per year NASA). With the warming up of the earth the sea will also be warmed thus creating stronger hurricanes and longer hurricane seasons. end There is no doubt that the earth in its own natural e volution would have created significant occurrences of climatic change.Thing such as continental drift, volcanoes, the earths tilt, the greenhouse effect and ocean currents are all parts of the natural order. We bash scientifically that the earths has been around for millions of years and there is no definitive time when these natural causes would have impacted climate change to the point where earth would have deteriorated to a stage similar to the planet Mars. What is puddle though is that the impact of mans lifestyle has negatively affected climate change to the point where the destruction of earth is now in the foreseeable future.Governments of nations around the world, advised by scientist have now embarked on programs to decelerate the speed of climatic change by developing green engineering which is the endeavor, commercialization, and use of processes and products that are viable and economical while minimizing the generation of defilement at the source and risk to huma n health and the environment. Green engineering embraces the sentiment that decisions to protect human health and the nvironment can have the greatest impact and exist effectiveness when applied early to the design and development phase of a process or product. (United States Environmental Agency) Man must now act to determine the natural selection of Earth Existence.
