Abstract
Global warming is a large increase in the Earth’s climatic temperature over a short period of time, and had become one of the most controversial topics that we have been facing. What impacts does global warming have on the atmosphere and what actions can we take to rectify the problem. Does global warming exist and what can we do about it?
Global warming is caused by natural and human interference. Some global warming differences with natural and anthropogenic climates changes are, natural climate changes include volcanic activity and anthropogenic changes are caused by human influences such as burning coal oil.
I believe that global warming is taking place; climate change has already had observable effects on the environment. Glaciers are shrinking, ice on rivers and lakes are breaking up earlier, plants and trees are flowering sooner. The changes in the weather is one indication, many places have been experiencing more floods, droughts and more severe heat waves. According to the Environmental Protection Agency (EPA), the average surface temperature across the contiguous 48 states has risen at an average rate of 0.13°F per decade. Average temperatures have risen more quickly since the late 1970s and seven of the top 10 warmest years on record for the United States have occurred since 1998, with 2012 being the warmest year on record.
A second indicator is the change in the sea level. After a period of approximately 2,000 years of little change, sea level averages has rose throughout the 20th century, and the rate of change has accelerated in recent years. When averaged over all the world’s oceans, total sea level increased at an average rate of 0.06 inches per year from 1880 to 2013. However since 1993 average sea level has risen at a rate of 0.11 to 0.14 inches per yea roughly twice as fast as the long-term trend.

...Impacts of Climate Change on Biodiversity 1. Introduction Climate change (also known as global warming) refers to an increase in mean annual surface temperature of the earth’s atmosphere, owing to increases in concentration of greenhouse gases such as carbon dioxide, methane and nitrous oxide in the atmosphere (Ninan, 2009). Biodiversity, on the other hand, is shorthand for biological diversity, and it is about the living world with which humanity not only co-exist but has evolved as a dependant part. The term biodiversity acknowledges that the natural world is a whole living system, and we are a part of it (Corlett & LaFrankie, 1998). The phase “climate change” and “global warming” are now a part of our lives and rarely does a day goes by without a mention, in the press or on the radio, of the possible causes of climate change and its consequences. This phenomenon has sneaked up on us in a somewhat short period of time and is accelerating at an alarming rate. It is perhaps the most serious problem that is threatening the civilized world today (Ninan, 2009). This paper postulates that climate change poses a serious threat on biodiversity. It will put forward evidence of how biodiversity has been affected worldwide, and will seek a solution to this problem 1.2. Biodiversity and its importance Simply put, biodiversity represents the fabric of life itself. It is comprised not only of numbers of species, but also includes the variety of all......

...Does Global Warming Exist? Team B BCOM275/ Business Communication and Critical Thinking February 13, 2013 Annie Moats Does Global Warming Exist? Planet Earth has been around for over four billion years. During this time it has gone through multiple weather patterns, to say the least. Ice ages and super storms have plagued the earth since the beginning of time. The issue that faces the world today is global warming. There is no doubt that the weather patterns are changing, but the question is if it is caused by humans or is it just in the natural process of the earth. Whether or not global warming exists is a controversial topic. It is easy to choose a side based on one’s opinion, but it goes much deeper than common knowledge. There are pros and cons to each side of the argument and it can be surprising what information is out there that has not even been publicized yet. Making an informed decision requires research into both sides. Also, the arguments surrounding global warming can change depending on which countries are discussing it. For several decades global warming has been debated within the scientific community and with society as a whole. Pro’s for Global Warming To understand global warming and its effect on the planet, the scientific principles need to be explained. The atmosphere is a thin spherical envelope of gases surrounding the earth’s surface. Its inner layer, the troposphere, contains the majority of the air that humans breathe.......

...1PHL1 Global warming or the high averages of global temperatures are caused by natural as well as human induced reasons. Though many people do not believe that global warming exists, evidences are coming up from all parts of the world supporting the occurrence of global warming. Many people are conveniently ignoring the warning signs produced by the earth; the important evidence of global warming is the temperatures itself. The average temperature across the world is higher than the previous years. Many areas are experiencing the highest temperatures ever recorded. There is evidence that due to this rise in temperature even the polar ice caps or ice glaciers have started to melt. According to reports, many countries around the world have been experiencing a very warm temperature even when to those countries that experience winter. Evidences show that the combined land and ocean temperature has increased than the average. According to the opinion of some experts, the temperature of the earth is rising at a rate of a fifth of a degree every decade. Scientists and experts reports that human activities are causing global warming, and if the present rise in temperature continues, the sea-level will increase and the arctic summer sea- ice will disappear by the second half of this century. There are quite substantial evidences showing that the climate change like, prolonged summer seasons, the increased heat waves and regular tropical storms are all resulted by global warming......

...Global Warming Global warming has been one of the most fervently debated and scientifically challenging topics of the 21st century. According to NASA, as early as 1904, Swedish scientist, Svante Arrhenius, was among the “first persons acknowledged to investigate the effects of doubling atmospheric carbon dioxide and how this would affect the global climate”. (1) As technology and scientific studies progressed throughout the 1900’s and into the 21st century, the effect of human civilizations on climate change was thrust into public spotlight. While fluctuations in the earth’s climate is a natural phenomenon, the vast amount of greenhouse gases expelled into the environment due to anthropogenic influence likely enhances, or acts as a catalyst, for overall climate change. Numerous studies exist that show increases in carbon dioxide levels throughout history via direct sampling as well as ice core analysis. In 1957, “Charles Keeling began measurements of atmospheric carbon dioxide from an observatory on the Mauna Loa volcano in Hawaii. He soon identified what became known as the ‘Keeling Curve’ – a graph that showed atmospheric concentrations of carbon dioxide increasing year by year.” (2) A quick view of the Keeling Curve, even by the untrained eye, shows a strong correlation between human industrialization and the sudden increase in greenhouse gases, See Figure 1. While the increases in CO2 alone does not point to human intervention, the clearly recognizable rise in...

... Does Global Warming Exist? Customer’s Name Institution Instructor’s Name: Course Name Does Global Warming Exist? Global warming is the increase in the earth’s temperatures as a result of human activities such as the burning of conventional fossil fuels, factory emissions, agricultural processes and greenhouse gas emissions. The human activities cause too much carbon dioxide to be emitted into the earth’s atmosphere resulting in global warming. The global warming processes involves the sun light waves entering and heating up the earth atmosphere and then are reflected back as infrared waves into the atmosphere. These infrared waves are trapped in the earth’s atmosphere together with carbon dioxide and greenhouse gases altering the earth’s temperature from normal conditions to extreme temperatures which are disastrous for human survival. Global warming has become a major social and scientific concern during the past decade. The facts about the existence of global warming are everywhere worldwide. The most crucial proof of climate change is of the melting of all the glaciers all over the earth at a rapid pace which some scientists predict would be catastrophic and cause real trouble by drowning cretin countries partially (Haugen, Musser & Lovelace, 2010). Another example is the spread of diseases such as dengue and yellow fever in certain......

Global Warming

...13 October 2009 Global Warming The Earth's climate is constantly changing over time. Many climatologists believe that the temperature of the Earth slowly fluctuates over time. In fact, several scientists estimate that between 15,000 and 30,000 years ago the Earth was covered by large sheets of ice. This period of time was known as the Ice Age. As the temperature of the Earth began to rise 7,000 years ago, the Ice Age came to an end. The first theory of global warming came in 1824 when French mathematician Jean Baptiste Joseph Fourier discovered that the Earth's temperature was slowly increasing. Fourier argued that the earth's atmosphere traps solar radiation and reflects it back toward the earth. In the late 19th century Fourier's theory was labeled the "greenhouse effect" when Nobel Laureate Svante Arrhenius coined the term to explain how carbon dioxide traps heat in the Earth's atmosphere. Today, scientists disagree on the effects of global warming while some deny the phenomena all together. Despite these arguments many historians point out the direct relationship between man and the environment, often referencing the American Dust Bowl of the 1930s, where large scale soil erosion reduced parts of Colorado, Kansas, New Mexico, Oklahoma and Texas to arid deserts. Currently, many governments and corporations are working to reduce fuel emissions and produce "Earth friendly" products such as hybrid cars. Yet, many scientists warn that global warming is an imminent......

...Professor Rudolph English 102 13 December 2011 Warming Up Topic The issue of global warming has been front page news for over a decade from magazines, newspapers, journal articles, books and even local news channels. This has begun 20 years ago when a Global Warming treaty was signed at the United Nation Earth Summit in Rio de Janeiro in 1992(Qtd. Harf p. 141). Global warming is the unusual rapid increase in the average temperature of the earth's atmosphere and is responsible for changes in global climate patterns. It occurs when greenhouse gasses including carbon dioxide, methane, black carbon, and other toxic gasses trap the heat and light from the sun in the earth's atmosphere, which increase the temperature. Some scientists agree that human consumption of the earth's natural resources and activities over the years had contributed to the earth's current state of being. However, opposing sides claim that there is no evidence to support this; rather it is just a bogus statement. They believe human action has nothing to do with the earth’s hot temperature. The controversy involves a disagreement over the fact, cause and consequences of the global warming. Both sides of the issue can find multiple experts to support their case that the earth is or is not warming, that global warming is either the consequences of human activities or a cyclical phenomenon and that global warming will be good for us or will bring tragedy. Global warming has created awareness amongst the......

...atmosphere, heating up the world. Global Warming is a growing problem and needs to be stopped now. Global warming is an interesting topic. There is confusion amongst scientists about what it really is. Global warming is defined as the release of green house gases into the air that trap heat on the earth, causing for warmer temperatures. The issue of global warming is also very up in the air, because many people do not even believe that it exists, and because of this, there is much debate about what people should do about global warming. Global warming is affecting the earth a lot, and it is affecting it fast too. This decade has been the hottest decade in centuries (Stuart, 11-01-2005). Because of this the polar ice caps are melting, and it could change the flow of the North Atlantic Current (The Day after Tomorrow, 2005). The change in flow could cause immeasurable effects to the Earth, and could change the weather that occurs on the earth dramatically. According to the IPCC 2001 report, the Earth's surface has warmed by about 1 degree Fahrenheit, and that is the biggest it has raised in centuries (Stuart, 11-01-2005). If the earth continues this pattern, there may not be a very hospitable area around in a few centuries. The hotter atmosphere on the earth causes the ocean temperature to rise, and coincidently hurricanes get more power from warmer waters, which is why hurricanes of late have been so damaging. Not only does global warming affect the earths weather patterns...

...the problem of global warming, in which the temperature of Earth is rising quickly than ever before, and it is affecting every aspect of life on this planet, from agriculture to animals to humans. It is believed by many, that the advance technology is one of the main reasons why it exists, but the debate never ends on this. Along with that, emission of greenhouse gasses and deforestation are also considered some main reasons for its cause. . Global warming is not just a scientific concern but also encompasses economies, geopolitics and individual lifestyle. Several policies have been issued throughout the world, with the motive of conserving our nature, and helping reduce its effect on our planet. Other than that, there are also several ways which every individual can follow, which in turn will contribute to fight its cause in one way or the other. Global warming is not just man made but is also a natural cause. There are definitely several man made causes, such as the carbon dioxide emissions from fossil fuel burning power plants. Most of the power plants are operated by burning fossils, and with the growing technology and new gadgets, we are dependent on using electricity for almost everything. Also, nowadays almost everyone have their own car, and to meet the demands, more and more cars made and used every day with the help of burning fossil fuel. When the gasoline is burnt in the atmosphere, it releases carbon dioxide, which is another cause of global warming.......

...Global Warming Anita Orzel Southern New Hampshire University Global Warming The earth has undergone periodic changes known as global cooling, and global warming. Today’s global warming is unique, due to human influences. American people should be concerned, as the world's scientific experts agree that industrial and land use activities are having an unfavorable impact on global warming. Burning of fossil fuels such as coal, oil, gasoline cause buildup in greenhouse gasses, in addition, deforestation, and destruction of ozone layer create global warming. Earth will suffer serious environmental damage if there are no precautions taken now to reduce global warming pollution. To prevent further damage to global warming caused by human activities, policies must be implemented and diligently enforced, all nations need to partake in action plan to implement policies such as fossil fuel conservation and recycling programs. Greenhouse gases help sustain life on earth by trapping heat from the sun and keeping the earth warm. Some greenhouse gasses develop naturally some occur from human activities. Naturally occurring gasses are, water vapor, carbon dioxide, methane, and nitrous oxide (An Overview of Greenhouse Gases 2009). Human activities, such as, burning of solid waste, fossil fuels such as, oil, natural gas, and coal, wood, raising of livestock, and industrial activities add to the greenhouse gasses, and destroy the ozone layer.

First we will look at comparing and contrasting natural versus anthropogenic climate changes and include examples of each type. We will then discuss which position I will take in wither global warming exists or not. After that we will I will assess two current mitigation strategies for global warming and analyze the effectiveness of the mitigation strategy. Lastly we will look at the policy changes that I would propose to help stabilize global climate, and what business sectors or nations would be held to stricter standards to my proposed policy. To start this paper off I will first look at comparing and contrasting natural versus anthropogenic climate changes and providing examples of both. But I think to start off we need to first know what natural climate change and anthropogenic climate change are. Natural climate changes are anything that effect the climate of the earth in natural ways, for example the sun, the moon, the atmosphere. But what is anthropogenic climate change? Anthropogenic climate change is defined as; “the production of greenhouse gases emitted by human activity” ("Anthropogenic Climate Change," n.d.).

Global warming is when the earth’s temperature increases, which is caused by greenhouse gasses such as carbon dioxide, water vapor, nitrous oxide, and methane. These gases trap heat and light form the sun in the earth’s atmosphere causing the temperature to rise on earth. Greenhouse gases are necessary for the survival of life on our planet but due to the large increase of average global temperatures people are pointing at human activity for speeding up the process to a degree that is deemed unsafe.

Some people believe that Global Warming is a serious problem where others may argue it is nothing to concern ourselves about. In this report, we will read some thoughts of some FOX News fans and see their opposing thoughts and comments. We will also read the debate between 2 Doctors who have very different views about Global Warming. Global Warming Global Warming is the rise in the world’s stratosphere and oceans since the latter part of the nineteenth century. [1] From before the 1900’s, the worlds mean surfaced stratosphere has increased by about 0.8 °C (1.4 °F), increasing by 2/3 since 1980.[2] Global temperatures increase causing sea levels to rise drastically bringing changes to the amount and the pattern of our precipitation which then expands subtropical deserts.[3] In the Arctic, it is believed that Glaciers, permafrost and sea ice is believed to be caused by the warming. Some different types of heat waves could be droughts, heavy rain and changes in crop yields. From all around the world we continually see the degree in which warming varies.[4] If the word “global” means temperatures increasing to 4 °C (7.2 °F)”, then limitations for adapting to our physical bodies is most likely exceeding in most......
