From the Paper
" Scientists all over the world are growing increasingly concerned about the steady build.up of trace gases in the atmosphere. Presently, the most abundant trace gas in the atmosphere is carbon dioxide (CO2). This has been due primarily to the use of fossil fuels. Several studies have concluded that CO2 emissions may alter the radioactive balance of the earth, increasing the global temperature and dramatically changing global climate (Jager, "Floating" 6).
The "greenhouse theory," which states that increases in CO2 will warm the earth, was first developed by scientists before the turn of the century. This theory holds that CO2 and other "greenhouse" gases in the atmosphere allow the sun's ultra.violet and visible radiation to penetrate and warm the earth, with the (...)"

From the Paper
"In late 1989 and early 1990, dramatic world events such as the fall of the Berlin Wall shared newspaper headline space with a debate over a problem in theoretical and applied climatology: the "greenhouse effect" of increasing global temperatures due to the increased level of certain gases, notably carbon dioxide, in Earth's atmosphere. The greenhouse question briefly became a matter of heated international and domestic political debate, as when the Bush Administration, influenced by Chief of Staff John Sununu, took a "hard line" against proposed measures to reduce the increase in greenhouse.gas levels .
Since that time, the public debate over the greenhouse effect has faded somewhat, not because scientific views of the problem have changed, but simply because the media and public, whose attention is short.lived, have gone on to other issues."

Abstract
A paper which examines the arguments that refute that it is not accurate to mainly attribute the problem of global warming to the increasing carbon dioxide emission caused by human activities. The paper discusses the issue of global warming and explores the reasons behind the argument that carbon dioxide emissions are most likely the cause of the global warming. This paper provides the necessary information needed to support the argument presented, as well as discusses and analyzes the opposing arguments that are given in light of this controversial environmental issue. In the last part of the paper the author contends that despite opposing claims refuting the main argument, increased carbon dioxide emissions are still the primary reason why global warming has been prevalent over the years.
From the Paper
"There are significant effects in the health of human beings and the environment due to global warming. Human health is threatened because too much heat in the atmosphere causes certain deadly diseases to propagate. Malaria is an example of this disease, which propagate under local climates (hot and humid climates). Excessive heat also result to respiratory ailments and death. Heat strokes attack many people especially when they encounter heat more than their body temperature can take or adapt to. Environmental elements such as water resources dry up due to excessive evaporation. Climate changes occur when excessive precipitation happens because of uncontrollable conditions in the atmosphere. Different landforms become barren and dry, making it impossible for plants to thrive. When this happens, animals that live in their habitats will leave, and may not survive. All of these effects in the environment contribute to the imbalance in ecological diversity."

Abstract
This paper discusses that concerns have been raised about a rising concentration of carbon dioxide in the atmosphere. The paper explains that the issue has been examined using climate models, such as the one called EDGCM based on a 120 year long model run, starting in 1985 with an increase in carbon dioxide in the atmosphere. The paper relates that a global climate model such as this allows for a study of climates in the past present and future.
From the Paper
"Such computer-driven models are one of the primary tools now used in climate research. The EDGCM model also serves as a learning tool for students and provides data to the public in a more easily-accessed manner than is true of some other models ("EDGCM: The Project" paras. 1-3)."

From the Paper
"The term "greenhouse effect" refers to the global rise in the earth's temperature within the biosphere as a result of excess man-made gases. The gas which is causing the most damage is carbon dioxide. Under normal circumstances, carbon dioxide is important for sustaining life on the planet. In the process of photosynthesis, plants absorb carbon dioxide and release oxygen into the atmosphere. This cycle is essential for the maintenance of human and animal life as well as plant life. However, in order for this process to be effective, there must be a balance between the amounts of carbon dioxide and oxygen that exist in the air. The problem with the greenhouse effect today is that there is too much carbon dioxide in the atmosphere. This excess gas is the result of pollutants which have been caused by the ..."

Abstract
This paper describes how greenhouse gases contribute to global warming. It begins by describing how greenhouse gases occur in the atmosphere. It discusses the importance of greenhouse gases and then describes what causes the harmful greenhouse effect. Finally, the paper describes the negative impact of the greenhouse effect on the Earth's environment.
From the Paper
"Greenhouse gases are components of the atmosphere that contribute to the warming of the Earth. Some greenhouse gases occur naturally in the atmosphere, such as: water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Human activities have increased the concentrations of these gases over time. The burning of fossil fuels such as oil, coal, and natural gas as well as other activities like deforestation, has lead to higher concentrations of Carbon dioxide. Live stock, paddy rice farming and losses of pipelines have lead to higher concentration of methane in the atmosphere. Activities, such as the use of nitrogenous fertilizers for agricultural reasons, and the burning of vegetation, have increased the nitrous oxide concentrations. The only greenhouse gas that is not directly affected by human activity is water vapor (Greenhouse gas, 2007)."

Abstract
The first part of the paper explains the natural workings of the greenhouse effect. In the next part, the paper details how human activity has upset the balance of greenhouse gases, thereby, giving rise to the phenomenon of global warming. The third part of the paper then looks at the environmental dangers that have been associated with the global rise in temperature. In the final section, the paper examines how people have tried to address the problem of global warming, both through technology and through legislation.
From the Paper
"Perhaps the most common misunderstanding about the greenhouse effect is the general view that this phenomenon is artificial or human-made. However, the greenhouse effect has kept the Earth warm and habitable for over four billion years. Without the thermal blanket of the greenhouse effect, the Earth?s temperature would plunge to an estimated 59 degrees Fahrenheit, making it uninhabitable for most of the living organisms on earth today (EPA).
As a natural phenomenon, the greenhouse effect is set in motion when energy from the sun heats up the layer of greenhouse gases in the Earth?s atmosphere. Sunlight is composed of a range of radiant energy, including several forms of radiation. When sunlight reaches the Earth?s atmosphere, the atmosphere then reacts with the sun?s radiation in three different ways."

Abstract
This paper discusses the effect that clouds have on the greenhouse effect. The paper is written as if it were discussing the opinions of three groups of scientists. The first group believes that clouds counteract the greenhouse effect; the second says they make it worse and the last don't know.
From the Paper
"The greenhouse effect is one of the least understood environmental problems. Most people think of the greenhouse effect in negative terms. However, it must be realized that the greenhouse effect is essential for life of earth. For example, in A Green History of the World Clive Ponting states, Without greenhouse gases in the atmosphere to trap outgoing terrestrial infra-red radiation, the average temperature on the earth would be about -18 degrees Celsius and too cold for life. These gases primarily carbon dioxide and methane, maintain the temperature at about 15 degrees Celsius (Ponting, 1991, p. 387)."

Abstract
The paper outlines the issues of the greenhouse effect in Australia. The paper gives group and individual viewpoints on the subject, listing proposed options that might solve this problem. The paper further examines how Australia relates to the international community on this issue. The writer concludes with a personal opinion as to the best solution to this problem.
From the Paper
"The Australian Government (2005), in an effort to better battle further environmental damage to its land, either by its own actions or through the actions of others, acknowledges that for the last several years and decades, "the national and international focus has predominantly been on strategies to reduce greenhouse emissions," and that despite its own readiness to fix the environment, there has been on the part of others "an unwillingness to devote serious attention to adaptation strategies." The problems which the Australian Government (2005) has identified and begun to battle have resulted in such environmental and weather effects as "an increase in annual national average temperatures..., more heatwaves and fewer frosts..., more frequent El Nino Southern Oscillation (ENSO) events..., reductions in average rainfall and run-off..., more severe wind speeds in cyclones..., an increase in severe weather events..., and a change in ocean currents.""

Abstract
This paper discusses whether or not the greenhouse effect is really responsible for the earth's warming over the last century. It brings up the theory that perhaps this a part of the earth's natural cycle. This paper then discusses the Milankovitch Cycles which details the natural changes that the earth undergoes and the effect of these changes on the environment. The author feels that this theory, as presented in the article, disproves the greenhouse effect theory.
From the Paper
"The same happens in reverse in a time of high temperatures.
The ocean circulation systems redistributes heat better and this accounts for the speed of the ice melting in the Antarctic.
Milankovitch Cycles are than able to explain the temperature differences noted in the Antarctic. The ice melting is a direct result of this rise in temperature. The higher temperatures effecting the ocean circulation system also adequately explains why the ice melts at a fast rate."

Abstract
This paper explores different attached greenhouses, their benefits and their components, including detailed descriptions of flooring, roofing, glazing, insulation and venting. It discusses how they conserve energy and how they are virtually self-sustaining year round.
From the Paper
"The 'glazing' of the greenhouse is also very important- this is the material that allows the sunlight to come in and stay there, making the greenhouse warm and allowing plants to grow, even in the coldest of weathers. The two choices for glazing usually come down to glass and plastic. Glass is a good choice for your greenhouse because it is scratch and weatherproof, stable at high temperatures, has typically clear views (when clean) and has good solar transmittance. However, it is very difficult to install and is expensive. Plastics like polycarbonates, polyvinyl fluorides and fiberglass-reinforced polyesters are cheaper and easier to install, strong and resistant to breakage, have shown better plant growth results, and have a high solar transmittance.

Abstract
This paper discusses the various sources of justifications to act against greenhouse gases and carbon dioxide, as two leading causes of an irrefutable trend toward global warming. The paper discusses the views of the critics and skeptics against taking these steps and then looks at the views of those in favor of the proposed actions against global warming.
From the Paper
"When the great majority of scientists independently come to similar or supporting conclusions, however, it is usually a good bet that they are correct. It would appear that the over-whelming evidence supports the idea that we are experiencing global warming, that human activity is contributing to this warming and that we can't afford not to act. I would agree with Stevens that there is a wide range of opinions on how much impact global warming is having and on how much humans are contributing. From the articles I have read it seems that there is very little scientific evidence AGAINST the global warming scenario. Skeptics seem to be focusing on discrediting the global warming supporters, rather than proving that there is no warming or that no human impact exists."

Global Warming, 2007.
This paper looks at automobile emissions, the greenhouse effect, development of technology and possible solutions to this worldwide problem.
917 words (approx. 3.7 pages), 3 sources, MLA, $ 32.95
»
Click here to show/hide summary
Abstract
The paper discusses how automobile emissions contribute to global warming because the presence of carbon dioxide, or methane, in the atmosphere raises the earth's temperature. The paper explains that the greenhouse effect is caused by excessive fossil fuel emissions, a result of human overuse and misuse of the environment, that causes the earth to heat up. The paper maintains that everyday citizens must take a stand against global warming. The paper suggests three solutions to this global problem and asserts that there is no international, or international relations issue, more important than global warming.
From the Paper
"Automobile emissions contribute to global warming because the presence of carbon dioxide, or methane, in the atmosphere raises the earth's temperature. In recent decades, international automobile manufacturers and governments alike have made some efforts to reduce automobile emissions, through measures like placing smog devices on cars; mandating smog inspections of cars and introducing hybrid automobiles."

Abstract
This paper begins by citing some statistics on carbon dioxide emission rates in the United States to demonstrate the need for changes in U.S. commuting policies and technologies. The paper then discusses two overall approaches that could be taken in order to cut the emissions of motor vehicles and suggests that these approaches are mutually supportive. The paper goes on to discuss the many environmental effects of carbon dioxide emissions and concludes with a warning of what will happen if the problem is not addressed.
From the Paper
"National Research Council brought out a report in 1997 recommending that important changes in the U.S. commuting policies, technologies, and activities may turn essential to minimize emissions of the motor vehicles and the following hazard of global warming at the time of the consequent century. And due to the fact that commuting has its part in the society of the nation and economy, there needs to be a balance created in mobility and need for access of people as against the resources of the environment and natural resource requirements. The report has said that there are two overall advances which have to be taken into account in cutting of the emission of motor vehicles of the generally termed greenhouse gases in course of time."

Abstract
This paper attempts to show how, by analyzing greenhouse gas uptake via measuring the trunks of different ages of tree stands, an estimate of carbon content can be derived. It looks at how the amount of carbon dioxide present helps to determine the success of the regeneration of deforested areas and the effects of mitigating global warming. It tests the difference in carbon accumulation in different age stands of trees to see which is most helpful in carbon accumulation and aiding in the fight against global warming.

From the Paper
"The data we collected is vital to the reduction of greenhouse gases and necessary decrease of global warming in this day and age. Awareness is key to this situation due to the fact that roughly 25% of annual greenhouse gas emissions from human activities come from the United States (Rubin et al, 1992). By knowing the proper means of reduction of carbon emissions, one can contribute to the conservation of the planet, and live a healthier lifestyle. Maintaining healthy young forests is crucial to reducing the effects of emissions. Carbon uptake is strongest in trees before 50 years of age. Therefore, deforestation and reforestation techniques are important in the window of time after this stage. By clearing out forests and planting new trees, carbon mitigation will increase again over the next period of 50 years."
