Protecting the Polar Regions From Melting Ice
Protecting the frigid Regions From Melting IceShould We Protect Environment from Climate form in The pivotal Regions?Kiwoong LeeThesis Statement We should shelter surround from thaw codsw everyop in the Polar Regions be excite if the glaciers of Polar Regions keep run, we get out all overleap the earths ecosystems.These days, reckless death of nature by gracious being has brought ecological catastrophe. For this reason, the Earth has gotten many problems much(prenominal) as closing of the environment. Melting applesauce in the Polar Regions is the most important among new(prenominal) problem. Many people argon not particularly concerned close to melting ice in the Polar Regions because it is too huge. A plow of people out of apathy attach the problem that present the Polar Regions condition. Causes of melting ice in the Polar Regions argon destruction of the environment. hence there ar some(prenominal) phenomena like nursery and increase nose furthert enddy d ioxide. This situation bring bad thing that increase the temperature, rapid lowland stand and destroy wildlife habitats. We should protect environment from melting ice in the Polar Regions.Glacier is that polar and alpine regions of the compressed stack of them are a long time ago to survive light by soberness and weight. Ice shelf ice is made up by bad chunks of ice. 10persentage of the inherent field of ice in Antarctica are labeled as ice shelves.The present Arctic condition is not good because of humor diverseness. The Arctic is single of the places where conditions are ever-changing the fastest of any mode system in the world, says Edward Blanchard-Wriggles worth, a UW doctoral student in atmospheric sciences. catamenia trends are so strong that it takes five days to settle a new mean (Science Teacher 16). The Arctic is melting so many animal lose their habitation because the Arctic is made up enormous masses of ice. thence many Polar animals fanny move possib le. However according to NASA (National Aeronautics and Space Administration), North Pole glaciers are melting down very quickly. They are losing their resting area so several kinds of animals is die from a drowning accident. And globular warm is also contri besidesing to the advancement in ocean aims by melting the glaciers of Polar Regions, and inhabitants of coastal area are losing their homes. Some scientists predict the area could be largely ice free in summer within years.In response, the Antarctica is not assorted from the Arctic. The Antarctica is more serious than the Arctic because Antarctica is a continent of land, surrounded by seas. Melting at the base of Antarcticas fimbul ice shelf is control by warm surface water, as well as intermittent pulses of warmer, deeper water ( Brown 143). Why is melting the natural and anthropogenic factors are factors. The Earths axis of rotation is or so 20.5 degrees, this is now endlessly constant, and gradually variegates to t hat. Earths orbit is an ellipse quite than a round of drinks, do not schedule too. In other words, changing the amount of incoming solar energy the Earths temperature may increase did not. Anthropogenic factors are worldwide warming. Of course not cause global warming, environment al issues, but it is not melting because of environment pollution. Melting of glacier is caused by factors that did environmental problem. world(a) warming emissions from human sources of greenhouse gas such as water vapor, nose candy solar rise in global temperatures is as a result. The research involves the Pine Island and Thwaites glaciers on the West Antarctic ice tacking, both of the five largest glaciers in Antarctica. Those two glaciers are important because they drain a large portion of the ice sheet. As they melt from below, they also gain speed, draining the ice sheet faster and contributing to sea direct rise. Eventually that could lead to global sea take rise of as much as 6 feet, thou gh that would take ascorbic acids to universal gravitational constants of years (Vince Stricherz). It is serious situation because melting of Antarctica is acquiring faster and faster. Now the Antarctica area is remaining 40persentage of the previous area.Global warming is the biggest cause of melting ice in the Polar Regions. It is kinds of environment pollution. Thus what is the global warming? It means that Earths average temperature is about 15degree in the ground to maintain controlled from solar radiation energy. Over the away 20 years, there were 0.5degree a rise in temperature but the mid-21st blow predicts 1degree a rise in temperature. This is called global warming. The global warming generates to increase carbon dioxide. Increased carbon dioxide not only warms the climate but it also dis clears in sea water making it more acidic. The global warming has been made, as increased greenhouse gases in the atmosphere take on radiant energy released to outer space. This is t he greenhouse of short-wavelength, which come from outside as the greenhouse effect is long wavelength of light reflection off from the surface, but passage is by absorbing the light of the internal temperature. Carbon dioxide can be called as a main cause of the greenhouse gases, but Chloro Fluoro carbons, nitrogen oxides, and methane gas are also other causes of them. due(p) to destruction of the Antarctic ozone, global warming continues to accelerate, so that the glaciers are being liquefied at the high speed. Because ozone is the thing made by sunlight, the ozone density over the South or North Pole is lower than other latitudes, oddly circulation of atmosphere in the wintertime stratosphere of the southern hemisphere makes a circle around the South Pole. This circulation of atmosphere prevents the middle stratospheres spread containing divide of ozone from flowing into the center of the South Pole. This phenomenon is similar to that the eye of typhoon is separated from the outside. At the air of Antarctic stratosphere separated in this way, formation of ozone stops during winter without solar energy. Therefore, climate switch overs and ecosystem is destroyed gradually.Increased carbon dioxide is one of the problems causes of melting ice in Polar Regions. Carbon dioxide has increased by 1.5ppmv each year and it seems that the rate of increase also has risen noticeably since 1980. In other words, average degree alteration of the denseness of Carbon dioxide in the atmosphere was in less than 10% before industrialization for one snow thousand years, but almost increased by 30% in two hundred years, compared before with by and by industrialization after 19th century. As the change of the world population, economy, technology, and social trend, it is expected that the submergence of greenhouse gases forget be changed considerably for many years to come. jibe to forecast of PCC (Intergovernmental Panel on Climate Change), regarding Carbon dioxide wh ich influence loosely on the atmosphere, under a condition that the world population becomes in two ways by 2100, and that economic growth rate be retained 23%, seventy hundred meg tons of total carbon dioxide emissions in 1990 will increase by two hundred million tons in 2100 the concentration in the atmosphere will be more than double by 2030, more than three times by 2100. Moreover, if the carbon dioxide emissions freeze like the level of 1990s, the time when the carbon dioxide concentration in the atmosphere is double can be postponed, but it was inform that the concentration will increase continuously for next two centuries. Due to this growth of carbon dioxide, the air temperature already increased by 0.30.6degree from 1860s to 1990s sea level also grew 1025cm. Furthermore, it was expected that this changes is get more noticeable exceedingly, compared with earlier 1900. In accordance with IPCCs prediction, the air temperature will shake up increased by 13.5degree average ly sea level will have grown by 1595cm approximately from 1990 to 2100. assumption that the air temperature changed in less than one degree for ten thousand years before industrialization, it can be said that this seriousness of the climate change caused by global warming is so big. As switch winds is getting weaker, the sea surface temperature in the middle pacific naval near the equator is higher than the normal temperature (2327degree) so that it is known that the frequent detail of El Nino phenomenon is also deeply related to the enhanced greenhouse effect. Depending on whether preconditions is realized or not, there might be a change of accuracy of results but as this abnormal temperature and the growth of sea level are significant changes, numerous changes that a human-being has never experienced can be brought down by destroying the physical and ecological balance which have been retained so far.As global warming and carbon dioxide are increasing, glaciers have collapsed from every quarter. The melted ice is flowing into the ocean at transcending speed. The reason why sea level grows is that glaciers are whiten white color reflects heat very well, so that the heat which the glaciers absorb will be decreased if the glaciers are melted. Therefore, thermal expansion happens because seawater absorbs the heat. For instance, if all of the Antarctic glaciers melted, sea level would increase by 60m. However, this old gravid ice wall has withstood offenses of global warming many times. Few years ago, scientists thought that the glaciers were so huge and dense that it was not too hazardous forthwith. Nevertheless, according to recent research, it can be predicted how high sea level becomes by simple calculation. The ocean will be wide with a growth of sea surface temperature for next one hundred years. If the entire world mountain glacier melted, sea level would increase more than 30cm. Thus, it is predicted that sea-level will increase by about 1m for th e next one hundred years. It seems that the increase is not very noticeable, but more than one hundred million people are still living in lower than 1ms sea level altitude. Many cities should invest an astronomical expense to establish a line of shore defense.According to climate change receive threat the Polar Regions ecosystem. Animals and microbic receive the highest damage. For example, polar condense lost their rest area as glaciers disappear. The polar bear will die out because it is getting more difficult for them to hunt prey. The microbial in Antarctica not differ because they decrease their number of an individual. If food range of a function is broken by environment, the Earth ecosystem will have a colossal damage.In conclusion, the Polar Regions is damaged their ecosystem by people out of apathy. We should protect from climate change in Polar Regions because our place to find sleep is on the road to extinction. So thats problem we will solve in the future. Many peopl e participate to protect from climate change in Polar Regions. There is some several remedy such as conserving electricity, planting a tree in order to cut out carbon dioxide and using transportation, etc. we can protect our hands. We should have wager in this problem.Works CitedArctic sea ice (Headline Science Current News in Science Research)(climate change and the condition to the Arctic sea ice). Science Teacher. 78. 8.
