Global Warming
Climate change is neither new nor unusual. Throughout the history of the earth, the average surface temperature, climate and greenhouse gas concentrations have changed, sometimes gradually other times quite sharply. During the past 10,000 years the earth has been in an interglacial period with a fairly stable climate, surface temperature, and greenhouse gas concentration1. The problem that has arisen in recent times is when scientists analyze the past 150 years, especially the last 50. Scientists have found an increased greenhouse gas concentration, making the 20th century the hottest in the last 10,000 years.
Although the earth has undergone periodic changes known as global cooling and global warming, today’s global warming is unique, due to human influences. The greenhouse effect is essentially gasses in the atmosphere trapping heat, rather like a car window does in the summer. The major heat trapping gasses found in the atmosphere are; CO2 and water vapor- which are found in large quantity, 03(ozone), ch4(methane), and N2O(nitrous oxide)-which are better heat trappers but found in smaller quantity, CFC’s and PFC’s- which are very potent and destroy ozone. The rapid elevation of these gasses in the past fifty years have been the cause for concern of scientists calling it a global warming problem.
Global warming is a natural process as well as a human assisted process. Solar flares and sunspots along with natural elevation of greenhouse gasses due to volcanic activety are the natural causes for global warming. Dr. Judy Lean, a leading astrophysicist, looked at global warming trends from 1860 to the present day. Her research has found from 1860 to 1970, global warming was largely due to natural sources. But from 1970 to the present natural sources accounted for only one-third the increase while human influence accounted for the remaining two-thirds of the increased greenhouse effect.
The increase in greenhouse gasses from human sources comes from a variety of things. Elevated Co2 levels, which have been increasing at a rate of 0.5% per year, largely come from the burning of fossil fuels(70-75%), especially coal. Deforestation and plant burning account for the remainder. Increased Methane and Nitrous oxide in the atmosphere are mostly due to agriculture; rice patties, cattle, termites and decomposition of dead...

...ns in order to stop the increase. In order to slow the increase, the efficient use of fossil fuels must be adapted. Natural gas gives off very little co2 and methane if burned properly. Deforestation must also be stopped in order to give natural co2 scrubbers, plants, a chance to aid in the process. Governmental programs have also been implemented. A carbon tax has been considered along with the passing of the 1990 Clean Air Act, aimed at lowering emissions and cleaning air pollution. On a world wide scale, the Kyoto Accord in 1997, in which 159 nations agreed to work together to decrease Co2 emissions by 5.5% by 2012. The United States agreed, since it accounts for 25% of the worlds total emissions by 1990 figures, to cut its emissions by 7%.
Global warming is still a major issue in world and U.S. politics. Conservatives argue for more market-orientated solutions, resulting in the imposition of taxes, resulting in higher prices for environment polluting goods. Liberals on the other hand advocate stiffer industry regulation and more direct controls. Any action taken, whatever the ideology, can only help to solve an increasing problem but at what cost to the consumer?
In the beginning, it often seems like there are two stories that only occasionally touch, eventually merging slowly to produce his finally conversion to the belief in a God. One side centers on is education, outlining Lewis' transformation for a neglected pupil under Oldie, an uneventful term at Campbell except for his sickness and glorious freedom at at home following, a floundering student save for some vibrant literature at Wyvern preparatory, and eventually to a priggish "nothing" at Wyvern College with a deep love of reading somewhat supported by Smewgy. Wyvern College actually pushed Lewis over the edge into pessimism, cynicism, atheism, and priggishness as well as drew him for a time to the occult and what he calls supernatural lust. It deeply contrasts with the side of his life that is punctuated with flashes of brilliant and pure joy followed by diligent search in-between, often though literature and music. The most notable literature being Wager,
Referring C.S. Lewis to culture now and although he has passed quite some time ago, his stories live on for believers and non-believers. Most known for his Chronicles of Narnia series, he has opened up eyes of many people. His theology and heart collide to continue showing God’s name and face wherever you go. Whether you believe or not, you know who C.S. Lewis is. An incredible life lived, and an incredible legacy that lives on. His belief in God and the Trinity, and his powerful message to the world through the power of his words will continue to test believers and non-believers to live a life filled with incredible purpose.
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
C.S. Lewis was a brilliant philosopher, theologian, and author. Many things influenced Lewis throughout his life, and inspired him to write over 30 books. Even 50 years after his death, he still continues to change people’s lives. He believed there were many dimensions to fantasy and imagination. He stated that, "Great stories take us outside the prison of our own selves and our presuppositions about reality. Insofar as stories reflect the divine maker in doing this, they help us face the ultimate Other--God himself, distinct as creator from all else, including ourselves." (Morrow). Lewis inspires people to believe in God, be creative, and never lose their imagination.
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
In addition to lowering greenhouse gas levels and using cleaner energy sources, there are things we can do as people to stop climate change. We could reduce our use of electricity at our homes by turning off the lights when we leave the room, turning down/up the heating/ac when it is unnecessary, and using less water. Also, we could install solar panels in our homes and donate money to environmental protection agencies. Hopefully, the people of our world will soon realize climate change is a pressing issue that must be solved as soon as
One of the most compelling and difficult environmental problems society is facing today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been slowest” (geocraft). There are no known solutions yet to reverse these effects in the environment, however there are many things people can do to prevent it from increasing. By implementing a carbon tax the government can tax corporations on how much carbon they emit into the atmosphere. With the extra money from the tax, scientist can invest in alternative ways to reduce how much carbon is emitted. Reducing climate change is going to take years and so nothing is going to get fixed anytime soon, but meanwhile we can use that extra money to begin cleaning up the atmosphere. There are many ways to explain climate change, some say its due to the emission of carbon dioxide (CO2) into the atmosphere, others say it is the burning of the fossils fuels, some even say it’s the greenhouse gases. All of these sayings mean the exact same thing, no matter how one says it. I believe there are more convenient ways to solve climate change; and if the government would to implement a carbon tax on companies they will then be forced to re-evaluate all the carbon they emit to the environment and red...
Grammar is essential to be taught in schools. Many educators are thinking about what levels of grammar should be taught in schools. According to Lynne Truss, an author of ‘’Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation,’’ Some public schools address that grammar is insignificant comparison to
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
A large part of an English teacher’s job deals with helping students find their own voices amidst the many teachings of their parents and peers. A student’s voice can be their values, their interests, and their perspectives of the world in which they live. Their voice can be their critical questioning of the many situations they face, whether in a text, the school cafeteria, or a park after school. It is the job of an English teacher to aid in finding this voice through their writing. It is by putting words and thoughts down on paper that a student can sometimes feel comfortable enough to take risks and find their true voices. Although traditional grammar instruction has long been thought to improve this skill, this is no longer the case. Instead, by providing a classroom environment in which students are immersed in classic literature from many genres including poetry, short stories, and novels, students will learn how to harness grammar for their own purposes of finding their voice in their writing.
It is not uncommon to say that grammar instruction plays an important role in language teaching. Regarding the status and importance of grammar teaching, a variety of opinions have been made. Batstone (1994) states that “language without grammar would be chaotic: countless words without the indispensable guidelines for how they can be ordered and modified” (p. 4). More vividly, Wang (2010) makes two similes. She compares grammar to the frame of a house, which is a decisive factor to ensure the solidness of it. Additionally, she regards grammar as a walking stick, whose function is to help and support students to learn English. Thus, the nature of grammar instruction manifests its own significance as it helps students enhance their overall language proficiency by integrating grammar into other aspects of learning, like listening, speaking, reading and writing.
These changes are becoming more prevalent in our world today, in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2, “The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed.
Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth. As for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
