...……………………………………………………………….. 10 Summary & Purpose People said that the global temperature is changing higher and higher. That is global warming which can happen the earth heat up. In addition, people said that the global warming happen because of the increase in the atmosphere of greenhouse gas concentrations like water vapor, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect. The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide. Therefore, this hypothesis test will show whether or not the global is warming compared by the previous year. In addition, the study will assess whether the global climate is changing at a higher rate compared the previous year. This data is based on NASA’s data of average of global climate, and all of temperatures are in Co degree. Hypothesis 1 H0: The mean global temperature for the period 1961 to 2010(µ1) is less than or equal the mean global temperature for the period 1911 to 1960 (µ2). Ha: The mean global temperature for the period 1961 to 2010(µ1) is greater than the mean global temperature for the period 1911 to 1960 (µ2). Hypothesis 2 H0: The mean global temperature for the period 1981 to 2010(µ1) is less than or equal the mean global temperature for the period 1951 to 1980(µ2). Ha: The mean global temperature for the period 1981 to 2010(µ1) is greater than the mean global temperature for the period 1951 to...

...ticking time bomb waiting to explode if nothing changes over the millennium. In a situation involving global warming, global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. The earth maintains a habitable temperature due to the Greenhouse effect, which allows heat from the sun to penetrate our atmosphere, without it, the earth would be a cold and hostile planet, and would most likely be uninhabitable. In author, Stephanie Pappas article entitled, “Carbon Dioxide is warming the planet (here’s how),” Pappas passionately argues that Carbon Dioxide is mainly to blame for global warming and not humans....

...In 2006, former senator Al Gore created an academy award winning documentary on global warming entitled “An Inconvenient Truth” . The movie earned several awards including an academy award for best documentary and gore later received a noble peace prize. The movie discussed several different topics of great concern to global warming; such as permafrost, climbs in temperature, extinction of species, drought, and fatigue to name a few. Four writers in five different articles discussed the three topics of greenhouse gases, climate change, and causes of global warming. These writers are writer and scholar Bill McKibben in “Think Again: Climate Change” and “How Close to catastrophe”; William J. Broad, writer for the New York Times in “From a Rapt audience, a call to cool the hype”; writer for the Cleveland Plain Dealer, Kevin O’Brien, in “Global Warming? I won’t be losing any sleep over it”; and Alan Zarembo, staff writer for the the Los Angeles Times, in “Game over on global warming?” All though the articles explain some different topics from one another, only one of them disagree with gore on the causes for global warming being humans, they all agree that there will be impacts to the environment, and all of them believe that greenhouse gases are one of the primary causes for global warming. First, all the articles discussed about who was to blame for the raising temperatures of the planet. The issue may be serious but O’Brien states that is just the media using another topic of...

...Global warming has been a heated topic of discussion for years. There are the people that believe in science and statistics, who say that is becoming more of an issue due to machine diagnostics and scientific evidence. The other side is the people that believe in religion and make choices by money, based on a plan created by god and an argument for our resources going to a cause that is inaccurate and impossible to fix. There does not seem to be a middle ground on this topic because you either believe in science or god, which has made this topic an ongoing debate with no results. The American Policy Roundtable is an organization in the United States that was founded on religion and republican views and they fund and profit from republican campaigning and success. Part of the Roundtable’s mission statement states “The objectives of the Roundtable model are built upon state-based public policy organizations, established in strategic states, all working to change America from "the bottom-up." Each state-based Roundtable organization serves under the auspices of the Board of Trustees of the American Policy Roundtable”. They state that they are a nonprofit organization, yet they have donations and contributions for radio station work and quote “Missionaries in the American field take care of their families as they serve the nation*”. The asterisk is further explained as “100% of the proceeds from books by David Zanotti, CEO, are contributed to the ministry”. Along with donations...

...Dictionary, they define climate change as the change in global climate patterns that are increasingly apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. The evidence of climate change has become more apparent and has increased its affects throughout the years and cannot go unnoticed any longer. This controversial issue is very important to take a stand on creating a better future for the world and get U.S. leaders to start the change in slowing down climate change while preparing for the worse. Since Earths formation 4.5 billion years ago we have experienced many different climates that range from sudden warming and cooling periods throughout decades. The world is constantly changing various examples are that seas have risen or fallen meters, jungles have spread or shrunk, and ice caps have melted all who have corresponded to the natural climate cycle (“Climate Change”). There have been global climate changes that have broken records from the past 1,000 years. These changes have happened from the use of atmospheric greenhouse gases and fossil fuels. Greenhouse gases are caused from heat being trapped in the atmosphere from the gas which warms the planet. Many say that it is a necessity of life in order to keep Earth living. The greenhouse gases have increased and created an unnatural source known today as “global warming”, and has created climate change. Since the Industrial...

...Article Rebuttal: Global Warming and Climate Change Jeffrey Rohde BCOM/275 April 1, 2012 Edward D’Avola Global Warming and Climate Change A controversial and heavily debated topic in the media today is global warming and climate change. Countless articles have been written about the impact of global warming on the climate changes. A majority of the global warming claims are based on either human factors or natural cycles. I came upon a recent article by Nina Chestney titled “Global warming close to becoming irreversible”. The article claims the global warming is a result of “the world's temperature looks set to rise by six degrees Celsius by 2100 if greenhouse gas emissions are allowed to rise uncontrollably” (Chestney, 2012). The temperature increase is the result of human activities. The purpose of this essay is to challenge the claims made by the author of the article. The rebuttal will be made by analyzing the credibility and validity of the author and their claims. The author’s credibility on the subject can be debated because of the lack of references listed. The points presented are, in a relative sense, true, but highly generalized. The author claims “the world's temperature looks set to rise by six degrees Celsius by 2100 if greenhouse gas emissions are allowed to rise uncontrollably”(Chestney, 2012). The author fails support the claim with data. The article discusses several negative impacts on the global climate: loss of...

...Agriculture plays a significant role in the country’s economy, contributing in 2000 about 2.9% of GDP, 10% of formal employment and 10% of the total value of exports. Agriculture as a percentage of GDP has decreased over past four decades, currently contributing around 2%. This implies that the economy is maturing, moving towards the secondary and tertiary sectors. However, farming remains vitally important to the economy with 638 000 people formally employed (Statistics SA, 2012 Q2) – although it’s estimated that around 8,5-million people are directly or indirectly dependent on agriculture for their employment and income. However, global climate change will affect the government’s efforts to alleviate poverty and fast-track development in rural areas. Definition of terms Global warming: refers to the increased temperature of Earth's surface, including land, water and near-surface air. Climate change: means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (UNFCCC). 2. Causes of Climate Change Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. They are factors that operate in favour of climate change; these factors that cause climate change can be divided into two categories. Those related to natural processes and those...

...Global Warming Romel Turner English 110 03-05-15 Global Warming is the change in climate in locations that shouldn’t be changing. We should be concerned about these things because if the climate continues to change in locations that aren’t to be that climate, such as Antarctica and the melting glaciers, or snow in the desert, it can harm the animals that live there and will harm our planet. I think that some people disagree because they don’t want to face the facts that our planet is changing drastically due to our actions, such as pollution to the air, land, and water. In the article 5 Scientific Reasons That Global Warming Isn’t Happening, by John Hawkins, he argues that global warming is mainly due to scientific reasons, not mankind. He says that there hasn’t been any global warming since 1997, and that the temperature of the planet has essentially been flat for 17 years. Following this statement, he says that the planet was cooling from 1940-1975, meaning that a 17 year pause is necessary to follow that. Hawkins believes that there are no scientific reasoning that global warming is caused by man. He says that over 31,000 scientists have signed on to a petition saying that humans aren’t causing global warming. He also says that Artic ice is up 50% since 2012, meaning that the Artic area has more ice, rather than it all melting away because of global warming. He states that predictions of global warming have already been proven wrong. He believes that global warming is a scientific...

...GLOBAL WARMING FACT OR FICTION BUSN300-1101B-17 Nadine Willis 15636824 March 24, 2011 Global Warming Fact or Fiction Global warming has been a hot topic for many governments in the last 20 years, with scientists on both sides of the issue. With many of the information that comes out is hard to common people to understand, it can make it hard for them to know what is true and what is not. There are some scientists that have been saying for many years that the way we like is causing a Green House effect on Earth. In simple terms, you think of a green house, farmers use greenhouses to trap warm air so they can grow plants that normally do not grow in colder months all year long. Now taking this in to a large scale, by driving cars, planes and other things that burn gas to run, we are putting more carbon dioxide in the air, which traps warm air, causing the earth to become warmer then what would be normal. Scientist have taken satellite pictures of the polar caps showing that the glaciers have been melting since 1850, which they claim is because of the increase of greenhouse gases, getting worse in 1980 to were some glaciers are completely gone. Because of this the sea level has risen 10-20 cm over the last 100 years, harming the coastal communities. There has also been a change in weather, scientist that globe annual temperatures is 1.0 F degrees warmer than they were in 1900, and the rate of warming has increased three times faster in the last 30 years. They believe...

...In the year 2014, it seems that there should be no doubt that global warming is among us and climate change is affecting the earth in a negative pattern. What many people are unsure about in regards to climate change include where it comes from, what the major implications could be if global warming is not addressed, as well as what we as humans living on planet earth can do to aide in creating a sustainable future. Through this article, with the help of experts, we will address all of these areas involved with today’s climate change. It is hard to pin point one exact cause for climate change because in reality there are many things that contribute to it. Al Gore points out in his speech that the burning of fossil fuels, namely coal, is the main reason that we are observing global warming. (Gore, 2009) According to the EPA, the electricity we create today by burning these fossil fuels accounted for thirty-two percent of greenhouse gas emissions in 2012. Although burning coal and fossil fuels is the number one source of greenhouse gas emissions, a surprising factor to climate change is the fact that agriculture makes up for nearly ten percent of greenhouse gas emissions. Agricultural emissions come from sources such as agricultural soils, rice production, as well as livestock, such as cows. (Environmental Protection Agency, 2012) Environmental author Anna Lappé also notes agriculture as being a large source of the greenhouse gas emissions weakening our planets health. Lappé...

...GLOBAL WARMING NAME INSTITUTION GLOBAL WARMING The gradual increase of temperatures within the earth surface has raised concerns off late. Global warming; which is the gradual heating up of the earth surface, has posed threats to the survival of flora and fauna and to some extreme extent resulted to the extinction of some species. Scientists have documented the statistics on the world changing temperatures since 1800. It is evident from the data collected that the earth surface temperatures have risen by 0.8 degrees Celsius over the past century. The Environmental Protection Agency has predicted that if the trend continues the in the next 100 years the temperatures are bound to rise from 1.33 to 6.42 degrees Celsius (Revkin, 2005). In this paper, I will exclusively look at some of the cause of global warming, effects and how the situation can be brought under control. Global warming is a human-caused state. This occurs when man releases too much of certain types of gasses in the atmosphere. These gasses commonly known as greenhouse gasses have resulted in depletion of the ozone layer hence the global warming effect. Increased emission of the gasses implies increased warming of the earth surface. Such gasses include water vapor, Methane, Carbon dioxide and Nitrous Oxide. Some levels of carbon dioxide in the atmosphere are considered natural. For instance, before the industrial revolution, the level of carbon dioxide in the atmosphere was estimated to be about 280...

...a moral case for reducing global warming. I am on Al Gore's side when it comes to the importance of raising awareness about global warming and on the fact that we should act forcefully to change the destructive influence humanity is having on the Earth's environment. The documentary is directed by Davis Guggenheim, an American director and producer, and features former United States Vice President Al Gore. Gore is also an author, businessperson, and environmental activist. He has been involved with environmental issues since 1976, when he was a freshman congressman. This documentary is set to educate, warn and raise international public awareness among viewers about global warming. It also states different solutions to fix this problem. Gore succeeds in doing so by presenting a comprehensive slide show containing real scientific statistics. He appeals to every individual by showing before and after images of our natural habitat, discussing a good number of graphs and diagrams. Quotes from Mark Twain, Upton Sinclair, and Winston Churchill underscore Gore's message of taking action, particularly when Gore quotes Churchill who said: "The era of procrastination of half- measures, of soothing and baffling expedients, of delays, is coming to its close. In its place we are entering a period of consequences." A good example Gore gives to induce fear in the viewers is the possibility of the collapse of a major ice sheet in Greenland, which could raise global sea levels by 6m, flooding...

...President Al Gore’s 2006 documentary An Inconvenient Truth: A Global Warning. Al Gore has been a long-time speaker and against global warming, and has advocated toward environmental energy efficiency and alternate fuel resources. In the years following his time in the White House, Gore focused significant time traveling throughout the world presenting the adverse effects related to global warming. This led to the creation of his documentary An Inconvenient Truth” A personal evaluation of this film considers the issue of the earth’s rising temperatures, the arguments and implications of global warming, how this topic challenged and broadened my understanding of science, and what significant elements I have taken away from viewing the film. This film is strongly connected to the Science/ Description breadth area because of its exploration of the earth’s construction and how humanity affects our planet, and many of the earth’s natural processes. According to the film, “The greatest venerable part of the Earths ecological system is the Atmosphere” (An Inconvenient Truth). One of the film’s global implications is that humans have the capability to irresponsibly damage the thin and protective layer of the Earth’s atmosphere called the Ozone. Each year, the Ozone is being thickened by pollutants causing more radiation from the sun to be trapped in the Atmosphere. In turn, the atmosphere steadily warms, hence the term, global warming. The U.S. Environmental Protection Agency (EPA) argues that...

...world tomorrow. Al Gore is making this argument evident in his film “The Inconvenient Truth”. This film gives statistics, experimental data, and other rather hard to grasp facts that prove how planet earth is being destroyed by our industrial societies. Statistics predict that within the next 50 years our planet will undergo several changes that according to experimental evidence has already begun. Scientist experimented to find out how much carbon dioxide was in the atmosphere and made connections between changes in the atmosphere. Naturally the amounts of carbon dioxide in the atmosphere change depending on the time of year. Carbon dioxide goes up in the fall and winter months and down in the summer and spring months. Now due to pollution the amounts of carbon dioxide in the atmosphere are unstable. Global warming is cause by carbon dioxide being trap in the atmosphere by green house gases which in turn increases the temperature. Everyday the amount of carbon dioxide is rising. Experimental polls of the earth say that the amount of carbon dioxide on the earth have never been over 300ppm since the beginning of time however now the carbon dioxide in the atmosphere are over 300ppm. In fact scientist predict that within the next 50 years the earth will project an unrestricted amount of carbon dioxide that will burn fossil fuels. This is a devastating fact. Global warming is destroying some of the planets most beautiful landmarks, such as glaciers, national forest, and mountains...
