Abstract
This nine page paper examines why global warming has become the primary threat facing polar bears. The writer looks at the Arctic polar bear population, which has been estimated to be approximately twenty-five thousand, of which about fifteen-thousand are in Canada, and has been impacted in a number of negative ways by climate change caused by air pollution. For example, the writer notes studies which have documented measurable effects in the body sizes and reproductive success of bears at Hudson's Bay and in other Arctic regions, and data that indicates that these changes are due to gradual climate change in the Arctic because of global warming.
From the Paper
"Based upon studies conducted over the last twenty years, many scientists have concluded that global warming has become the primary threat facing polar bears. The Arctic polar bear population, which has been estimated to be approximately twenty-five thousand, of which about fifteen-thousand are in Canada, has been impacted in a number of negative ways by climate change caused by air pollution. (Stirling 12) For example, studies have documented measurable effects in the body sizes and reproductive success of bears at Hudson's Bay and in other Arctic regions, and data indicates that these changes are due to gradual climate change in the Arctic because of global warming."

Abstract
This paper describes the causes of the global warming phenomenon that have been a part of earth's geological history since the dawn of geological time. The paper also looks at the effects that global warming has on the earth and in particular its effects in the Arctic Circle.
From the Paper
"Climate change in general, and global warming in specific, are by no means new phenomena. Since the dawn of geological time, surface and atmospheric temperatures on Earth have fluctuated enormously. In some cases, worldwide climate change has led to actual shifts in land masses, leading to changes in the ways human beings and societies evolved. For example, global climate change caused the so-called Ice Age: "During the Quaternary period (the past million years) the ice cap has repeatedly spread to middle latitudes over the sea, with corresponding glaciation on the continents," (Gribbin Forecasts 73). The disappearance of the dinosaurs and other prehistoric creatures may in fact be due to climatic changes. Global warming has also been intense in our geological history: between ice ages, it is possible that no portion of the earth was covered with glaciation whatsoever (Gribbin Forecasts 73). Moreover, such massive temperature and climate transformations probably did not occur as a result of human intervention, but rather were a result of complex environmental, meteorological, and astronomical influences. Climatic fluctuations are indeed natural and inevitable."

Abstract
This paper describes the different steps in the process of global warming, describes its primary causes, and explains how the problem of global warming is exacerbated by the effects of global warming in the Arctic.
From the Paper
"Global warming is no myth. Since the Industrial Revolution, the earth's average surface temperature has risen about one degree Fahrenheit, "with accelerated warming during the past two decades," according to the United States Environmental Protection Agency ("Climate"). Most of the global warming that has occurred over the past several decades is a direct product of human activities: factory emissions and automobile emissions especially. The emissions from factories and automobiles create what are known as "greenhouse gases," mainly carbon dioxide. The earth actually has a natural "greenhouse effect," a layer of the earth's atmosphere that keeps surface temperatures warm enough for biological life as we know it. Without a natural greenhouse effect, Earth surface temperatures would be far lower than they are now. However, the overall rise in the Earth's surface temperatures since the Industrial Revolution has occurred far faster than it would have without human intervention. Accelerated global warming can have dire consequences for life on earth. For example, according to Kate Ravillous of New Scientist, the west coast of the United States could suffer a severe water shortage by 2050 due to global warming. Most of the culprits of global warming exist in the most heavily industrialized and populated parts of the world such as the United States and Eastern Europe. However, the geological and environmental factors that directly cause global warming occur in one of the most sparsely populated regions of the globe: the Arctic. Global warming begins with anthropogenic factors such as auto emissions, proceeds to rising Arctic surface and air temperatures, and becomes magnified by several positive feedback mechanisms. In fact, if left unchecked, global warming in the Arctic will account for most of the damage incurred by the phenomenon world wide because of the positive feedback mechanism."

Abstract
This paper discusses the increase in global warming and the factors that are contributing to it. The paper discusses the different effects that global warming is having in different parts of the globe and how it is affecting the plants and animals of the various regions. The paper ends by specifically discussing the effects of global warming on polar bears and how it has led to polar bears being on the endangered species list.
From the Paper
"World Watch reports that the Arctic is now warming at nearly twice the rate of the rest of the globe (Mastny 2005). This warming is accelerating ice melt at the North Pole and presents serious implications for the region's wildlife and people, global sea levels, and overall planetary warming (Mastny 2005). The ice could disappear almost entirely over this century, "creating a feedback loop that accelerates overall planetary warming by replacing the ice with darker water surfaces that absorb the sun's heat" (Mastny 2005). Moreover, seals, seabirds, and other animals that depend on food found at the ice edge are also beginning to suffer from the changing Arctic climate (Mastny 2005). Changes in the ice cover in northern Canada have led to hunger and weight loss among the polar bear population, and scientists project that some regions could become uninhabitable for the bears within twenty years (Mastny 2005)."

From the Paper
"From all of the science, it really does seem that global warming and rising sea levels could pose a huge danger to our future survival on this planet. If you think this is true, it's time to start thinking about what you can about reduce global warming. If you live near the coast, buying a lifejacket might not be a bad idea! But seriously, there are things you can do. For example, you can start by selling that SUV and buying a bike. And then use the profit to buy stamps and write your MLA - because all of us need to be doing something about this."

Abstract
This paper examines the eating and sleeping habits of bears including their hunting and hibernation customs. It also looks at their mating habits and the "relationships" between mates and offspring. A physical appearance of each type of bear is provided through photographs.
From the Paper
"Bears are animals that are found all over the world. No matter what the climate, you can find a species. Most bears have the same features; powerfully built bodies, long heads, short rounded ears, and small eyes (Grizmick?s Encyclopedia). Most bears also have five long toes with arched claws that are incredibly sharp. In this paper I have decided to discuss the three most predominant species. ? No other animal has made such a strong impression on the peoples of the Northern Hemisphere; as long as the lion was still unknown, the bear was considered to be the king of beasts. (Grizmick?s Encyclopedia).? "

Abstract
This paper deals with both the scientific and political details of global warming. The author describes how global warming is a disturbing and controversial trend that has received increased attention in recent years and how politics often come into play when dealing with international global warming issues.
From the paper:
"Global warming has been a topic of scientific research and debate for decades. In recent years there has been a significant increase in public and political concern over the issue. Many people wonder if global warming is nearly as bad as scientists claim it is. Some question its very existence, insisting that the world is wasting its time and money researching the effects of global warming. Although many people believe that global warming is not a problem, it is an important issue because there are international complications, there is sufficient evidence of its existence, and it is a potentially dangerous situation."

Abstract
In this article, the writer discusses that the planet is currently facing the challenge and danger of global warming. The writer maintains that science and technology have brought us to this crisis, in that industrialization has led to global warming. It seems highly likely that we will have to rely on these very same things, i.e. science and technology, to rescue us from the peril we are in due to global warming. Within the ambit of scientific responses to global warming, two basic kinds of response exist: mitigation of global warming, or adaptation to the effects of global warming. This paper examines the research to determine which approach seems more appropriate and useful for saving ourselves from global warming. It recommends that we look to adaptation using science and technology, as mitigation has clearly failed.

Abstract
Essay
From the Paper
"Examples include sequestering carbon in trees. This would involve planting a vast number of trees, because trees take in carbon dioxide. They incorporate in into their leaves, roots and stems via photosynthesis. Due to the long life of trees, this would mean that the carbon had been sequestered away from the environment for about 100 years. Another approach is carbon management, in which carbon dioxide emitted during the burning of carbon fuels is caught and then sequestered away from the atmosphere. The question of course is where to store it. One suggestion is to sequester it in the ocean. The problem with this solution is that we do not know what the long-term effects on the ocean would be. In addition, the technologies to capture carbon dioxide emissions are still in the very early stages. Fertilizing the ocean with iron is an innovative idea propounded by an oceanographer in 1987."

Abstract
This paper looks at how global warming is an issue that is often discussed as if it is a certainty, with considerable concern created about what will happen to the planet if continued global warming is not prevented. It considers whether global warming is a real problem by describing the nature of it including the role the greenhouse effect plays. It is followed by a consideration of some of the arguments made against global warming. By describing the nature of global warming, the role of the greenhouse effect and the arguments against it,the author makes an informed decision about whether or not global warming is an issue of concern.
From the Paper
"It is noted that human activity is not the only way to create greenhouse gases. Methane is naturally produced by cows and other animals and carbon dioxide is naturally produced by plants. However, human activity is thought to be the reason that greenhouse gases have increased significantly enough to effect global temperatures. The environmental protection agency (EPA) notes that ?since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15%? (EPA). Pollution, deforestation and increased agriculture are also thought to be part of the problem (EPA). This means that while natural processes do change the concentration of greenhouse gases, human activity in the last century is thought to have changed greenhouse gases so significantly that global warming results."

From the Paper
"The findings of the Intergovernmental Panel on Climate Change or IPCC are stark and shocking and have already impacted on contemporary social consciousness. The important aspect that needs to be emphasized is that, unlike previous reports and assertions about climate change, the present report by modern scientists have achieved a sense of legitimacy and finality about the present situating. There seems to be, in effect, less possibility that these findings are speculative or questionable. "
"The findings are severe and rigorous in their view that the impact of climate change is potentially life - threatening and could result in the demise of human civilization if it is allowed to continue unchecked."

»
Click here to show/hide summary
Abstract
This report looks at the problem of global warming as a theme for research into the attitudes of the public at large about global warming as a scientific and media based issue of concern. The research is important because it can show connections or disconnections that the general public have about global warming theories and measure attitudes and beliefs toward this complicated issue. The objective of the current report or study is to give randomly sampled members of the general population a questionnaire about global warming and then compare results with extant reportage on global warming, to measure public attitudes. The experimental outline was formed using the qualitative survey methodology. Important or relatively interesting results include an apparent disconnect in public perceptions of the connection between ozone layer depletion and global warming. The current report introduces the problem or issue, explains the issue and finishes with a discussion and concluding remarks, including areas for future research.

From the Paper
"Working globally in concerned international communities is seen to be key to solving the problem and reducing greenhouse gas emissions. But steps must be taken to reduce the threat of global climate change at the individual, local, state, and national, as well as the international, level. Steps could be as complicated as urban design and waste management research, or as simple as planting a tree. Many cities have voluntarily taken the initiative to improve the environment by implementing greenhouse gas reduction strategies. These strategies can help communities save money as they lower the risks to human health caused by global warming. People must be willing to work together from the individual to the international level to find beneficial answers and solutions to the problem."

From the Paper
"Many environmental experts as well as scientists and medical experts are becoming increasingly concerned about the effects of global warming over the past few decades. This sense of alarm is fueled by the fact that many hypothetical theories and predictions previously made about the probable effects of extreme weather and climatic changes and believed to be an indication of global warming, are in reality occurring worldwide. These events have caused scientists to forecast even more extreme effects of global warming for the future."

Abstract
This paper examines the increase in global temperatures and how this is directly related to human activity. The writer looks at a report which states that the current decisions made by the majority of developed nations are a direct contribution to global climate change and that climate change is reversible with minor financial commitment and infrastructure change on the part of these developed nations. The paper explains that in order for positive change to occur, it is necessary for all countries to commit to reform. The writer notes that researchers have developed low-cost strategies to curb the precursors to global warming. The paper concludes that these strategies are likely to improve the economies of most countries through increasing job opportunities, and by helping to stop global climate change while the planet is still able to recover.
From the Paper
"Each year, almost one million persons are lost within sub-Saharan Africa to drought, water shortages, and lack of food (Young, Dooge,& Rodda, 62). Global warming has been linked directly to these outcomes, as well as other changes in ecologies throughout the world. Researchers argue that global climate change will potentially be the single greatest challenge faced by the human race, but also that if actions are taken immediately then the negative outcomes of global warming can be stopped. Moreover, there is a moral imperative that global warming be stopped in order to help those hardest hit by its outcomes, such as those currently dying in sub-Saharan Africa."
