Abstract
The paper presents the thesis that as global warming causes the earth's average temperatures to rise, crop production will experience a decrease. The paper discusses how temperature extremes have been shown to dramatically reduce the agricultural productivity potential. The paper relates that technology will play an important part in the production of crops and wealthier countries will be better prepared for technological supports. The paper points out that while there are conflicting reports concerning the specific effects of global warming and climate change, it is clear that farmers must be willing to enter a process that includes ongoing assessment and adaptation to the changes that are occurring.

"One important factor to crop production, and specifically fruit crop production is that failures are likely to occur due to the early growth of these crops in warmer weather resulting in the loss of crops due to cold snaps. This has been noted in the research in the foregoing literature. As well, there are agriculture crops that will initially be more productive however, the literature in the foregoing review has illustrated the likelihood that in the longer run, crops certain crops will be less productive due to higher temperatures."

Abstract
The paper discusses how, as the Earth's average temperature rises, crop production decreases. The paper notes the significance of a decrease in crop production and provides a literature review. The paper shows how, in general, global warming has a negative effect on crop production and the unpredictability of climatic change can also have a negative effect on crop production when farmers are ill-prepared. The paper points out, however, that although many crops will suffer, certain crops such as winter wheat seem to thrive in the global warming models.

From the Paper
"Peng et al. (2004) explore the affect of higher night temperatures, from global warming, on rice production. They evaluated these effects by a direct study on the effects of global warming on crop production, by analyzing weather data at the International Rice Research Institute Farm, from the years 1979 to 2003. They examined temperature trends and how they related to rice yield, by using the data obtained from irrigated field experiments, that were conducted at the International Rice Research Institute Farm. The researchers found that rice production fell 10 percent for each 1o C increase in minimum temperature. However, maximum temperature had an insignificant effect on crop yield. Therefore the researchers concluded that there was direct evidence that rice yields decreased with increased nighttime temperature associated with global warming."

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 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 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."

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 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."

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."

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."

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."

Abstract
This paper begins by defining and explaining the problem of global warming. It then looks at what causes global warming, giving an explanation that global warming is sometimes referred to as the greenhouse effect because it is these "greenhouse gases" that are most commonly cited as being responsible for this phenomenon. The effects of global warming are also discussed and finally a brief discussion about how we can stop global warming is the concluding section.
From the Paper
"Global warming has been the subject of much debate since the concept of the greenhouse effect was first introduced by Nobel prize winning scientist Svante Arrhenius in 1896. Inspired by the onset of the industrial revolution, Arrhenius theorized that the earth's temperature would rise as a result of the mass consumption of fossil fuels. However, he postulated that humanity would flourish in a warmer climate, whereas there is a growing consensus in the scientific community today that just the opposite is the case. "

From the Paper
"According to A Primer on Global Warming, life on earth is dependent on the so-called "greenhouse effect," which keeps the planet about 59 degrees F warmer than it would otherwise be. It was the French mathematician and physicist Jean Fourier who first described in 1827 how Earth's thin atmospheric blanket warms the earth. The atmosphere, Fourier suggested, possesses special greenhouse-like properties that permit solar energy to enter and strike the earth as visible light, but which then impeded the energy's return into space as infrared heat. These "properties" are in fact the so-called greenhouse gases, which permit solar energy as visible light to pass through the atmosphere, but which absorb and re-radiate a portion of the same energy as it leaves Earth's surface as infrared heat. The net effect is a warming of the atmosphere. The relative warmth of a cloudy versus a cloud-free night sky is an accentuated example of this effect, since the water vapor making up clouds is itself a greenhouse gas."

Abstract
This paper looks at global warming and its impact, both climactically and politically, upon Canada. In particular, the paper asserts that global warming has impacted Canada's environment in a tangible way and has also transformed Canadian politics - perhaps not for the better. Additionally, the paper examines how global warming is impacting vulnerable wildlife species and aboriginal or native societies in various regions of Canada. Furthermore, the paper looks at global warming's effects upon Canadian politics, with special attention devoted to the charged rhetoric surrounding the issue. The paper concludes that global warming is sharpening the ideological and political divide between those Canadians who believe something drastic needs to be done and those who do not feel so inclined.
From the Paper
"The more temperate Northern Canadian climate also has serious implications for ultraviolet B exposure in Canadian inland waters. Although one recent study suggests that "dissolved organic matter-mediated ultraviolet B exposure" is not a serious problem for those Canadian inland waters that were examined, the same report also found that "optically clear" and at-risk ponds were much more common (perhaps even surprisingly common) in the artic eco-zones - particularly in the Northern artic and in the artic cordillera (Molot et al, 2511-2512). To sum up this entire section, Canada's climate is changing in ways that put many aquatic and terrestrial species in harm's way."
