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.""

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
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."

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 (...)"

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)."

The natural greenhouse effect
The enhanced greenhouse effect
Global warming ? a controversial issue
Global warming ? the political debate
From the Paper
"Global warming is a highly controversial subject. While the basics of the greenhouse effect are quite well understood predicting what might happen if greenhouse gases continue to be released in the atmosphere is unclear. Owing to the fact that there is no consensus over global warming among scientists it is of great importance to look at global warming from an objective point of view. This essay is based upon information given in various publications. However, most publications provide biased information."

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
In this article, the writer notes that global warming is an issue that has been occupying Canadian as well as global headlines recently. The writer points out that although the severity of the problem has been recognized for quite some time, global warming has only recently become a 'mainstream' issue amongst Canadians and public interest in putting pressure on the governments of the world, to take action. The writer then discusses that this is a complex and all consuming task that requires extensive commitment and cooperation not just of governments, but also of industries of the world. The writer maintains that the main obstacle cited to pursuing the reduction of the greenhouse gases is the fear that it will negatively impact the economy and cut jobs. The writer concludes that many scientists, including David Suzuki and the United Nations IPCC, believe that any further increase in greenhouse emissions will devastate economies in the long run and keeping greenhouse emissions near current levels would cost only a very small fraction of the world's economic output.

What is the Greenhouse Effect?
What is Global Warming?
The Effects of Global Warming and Global Climate Change
From the Paper
"The Sun provides earth with great amounts of energy, of which about half is reflected or absorbed by the atmosphere. Ultraviolet light is absorbed by the ozone layer, while infrared (heat energy) is absorbed by the CO2 and water in the atmosphere. The energy absorbed by the earth surface is reradiated back into space. However, while most of the solar energy reaching the earth is visible light, the energy reemitted by the Earth is mainly infrared. This infrared energy is absorbed by the CO2 and water in the lower levels of the Earth's atmosphere. Because of this naturally occurring effect, the Earth's surface temperature is such that the planet is capable of sustaining life. This phenomenon is called the 'greenhouse' effect."

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
The paper argues that the world needs to act to curb the greenhouse effect and the resulting global warming. The paper examines how human activity related to industrialization has upset the natural balance of greenhouse gases that have kept this planet habitable. The paper also discusses how people have tried to address the problem of global warming through technology and legislation and argues that a balanced and global approach must be adopted to bring the greenhouse gases back to their original levels. The paper asserts that people must be willing to make sacrifices, to use less gas and to convert to more renewable energy sources.
From the Paper
"The planet's natural ability to trap heat at necessary has kept if habitable for over four billion years, and maintaining this delicate balance is important for the planet's survival. The thermal blanket of heating gases has kept the earth warm and habitable. If not for these gases, 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)."

Global Warming, 2002.
This paper is a structured argumentative essay which debates that global warming is a natural process and that the greenhouse effect argument is unsupported.

Abstract
This paper is a structured debate, arguing three points in support of global warming as a process: The current increase in temperature is a part of the natural cycle in the earth?s temperature; Milankovitch cycles adequately explain the effects of warming and the effects seen are explained by the earth?s natural systems enhancement. The author also refutes the common arguments made to support the idea of the greenhouse effect. A formal outline is included.
From the Paper
"The first argument was that the observed increase in temperature is a result of natural variations in the earth?s temperature and not a product of man?s impact on the world. This argument is because the earth has natural variations in temperature and that these natural variations are an adequate explanation for the changes in temperature observed. Since the exact cause of the increase in temperature cannot be known, this argument is not proof that the greenhouse effect is not occurring, but is proof that the impact of man is not necessarily the cause. This proof at least adds to further consideration of the issue and to questioning the assumption that the impact of man must be the cause of an increase in temperature."

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.

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 ..."
