How are human activities the primary sources contributing to global warming that has occurred over the past 50 years?
Abstract
The topic of global warming is of much controversy, as many scientist argue whether or not it is a real phenomenon, or if it is human induced or naturally occurring in our environment. However we can clearly see that there are many changes in our climate as we are been affected by higher temperatures and other adverse weather conditions, which all point fingers to the theory of global warming.
The aim of this research paper, is to provide information to the uneducated masses, about the factors that contribute to global warming, identify the effects of global warming, and show how global warming has changed over the past 50 years and to illustrate how human activities have contributed to global warming, while providing recommendations to minimize its effects.

Introduction

Since its conception, global warming has been one of the most controversial topics debated among many scientist and politicians. For the past twenty (20) years, the controversy surrounding the issue is whether or not we as humans have in fact created the proposed phenomena, or if we have acted as catalyst and increased the occurrence of the process all together. A few individuals, like Habibullo Abdussamatov a climate researcher, however deny the fact completely that global warming is actually occurring in the environment. Many arguments are being constantly raise by global warming, such as: Does global warming exist? Are humans to be blamed for the phenomena? Or is it just a natural cycle that occurs in nature? With all the debates and questions, the uneducated masses would wonder, what is global warming? According to the Merriam Webster dictionary, global warming is defined as an increase in the earth 's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution.
So is this phenomena real? Roach 2010 “evidence suggesting global warming is overrides any arguments

    Anthropogenic climate change is an establishment phenomenon. Within the scientific community, the question is no longer whether climate change will occur, but at what rate, with what effects, and what, if anything, we can do about it. The biggest culprit in climate change is an increase in atmospheric carbon dioxide, which is generated primarily through burning fossils. Earth’s average temperature is based on daily measurements taken at several thousand land based meteorological stations around the world, as well as data from weather balloons, orbiting satellites, transoceanic ships, and hundreds of sea surface buoys with temperature sensors. Scientists around the world have researched global climate change for several decades. As the evidence has accumulated, the most qualified to address the issue have concluded that temperatures have increased over the past century, that it is extremely unlikely that natural causes can explain the warming, and the human produced greenhouse gases are the plausible explanation for the warming that has occurred.…

    The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that there is no connection between the two, and that the Earth is just going through its natural cycle.…

    Global Warming is an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. Thus there is no indication that the warming between “1975-1998” and “1975 to 2009” is unnatural, unusual and/or caused by anthropogenic carbon dioxide emissions. Global Warming may have started in 1975, but there is no observable evidence of anthropogenic carbon dioxide emission based global warming began in 1975. Most climate scientists agree the main cause of the current global warming trend is human expansion of the “greenhouse effect” warming that results when the atmosphere traps heat radiating from earth towards space.Yet the big question standing still is, is Global Warming real? Well here's what you need to know about the warming planet, how it's affecting us, and whats at stake. In recent years, global warming has been the subject of a great deal of political…

    The view that human activities are likely responsible for most of the observed increase in global mean temperature ("global warming") since the mid-20th century is an accurate reflection of current scientific thinking. Human-induced warming of the climate is expected to continue throughout the 21st century and beyond.…

    Global warming’s a severe concern that is plaguing our environments and communities. Global warming occurred when the rise in the average temperature of both the Earths atmosphere along with the oceans. Since early 20th century the Earth’s temperature has continued to raise giving merit to the beliefs that global warming warrens concern. Jiansong (2011) believed tropical storms became worse over the years and global warming has become such an issue become such an issue it needs to be combated. Miller (2012) preformed experiments to measure the change in the earth’s tempters over the years. Venkataramanan (2011) believed that global warming led to an increase of disasters like hurricanes, droughts and floods; Sherman (2010) believes global warming was a severe problem. Sherman (2010) people must first look at the global temperature change, secondly people must observe the climatic changes, and lastly people need to forecast the weather trends to get a better understanding of what global warming really is and how we can improve our surroundings. Jiansong (2011), Miller (2012), Venkataramanan (2011), and Sherman (2010) discussed the global temperature changes.…

    Global Warming has become a major issue in our environment within the last couple of years. Why should we care about that though when we have our own little set of problems to worry about? Maybe because an increase in temperatures can cause a rise in sea level, an increase in the intensity of already extreme weather events, and considerable changes to the amount and pattern of precipitation. All of this may lead to a vast space of tropical areas and will increase the speed of desertification. The more we look into how global warming we think “What is the cause of it all?” Many have thrown around ideas about what they think the cause might be but no need to throw anymore because new evidence has shown that we are the cause of Global Warming.…

    Controversy over global warming exists as a dispute regarding the nature and consequences of global warming. The theory of global warning as presented in the mainstream media currently assumes that carbon dioxide is an atmospheric greenhouse gas and since humans are producing more carbon dioxide than previously, the temperature must therefore rise. The cause of global warming is not actually known, but in it 's simplest terms the debate boils down to whether or not global warming is caused by human interference or part of a naturally occurring cycle. The debate has recently become one-sided in favor of human interference due mostly to three factors: political pressure on scientists to produce research that supports the global warming theory, public misconception of what scientific consensus is, and an irresponsible that media promotes sensationalized viewpoints to sell advertising.…

    Climate change, often referred to as global warming, is a rising issue that has been further developed over recent years. To clarify, the term ‘climate change’ refers to any significant change in the measures of climate lasting for an extended period of time. Such changes include but are not limited to major changes in temperature, precipitation, or wind patterns occurring over several decades or longer. Therefore, the specific term ‘global warming’ is only one aspect of climate change and used when referring to recent and ongoing rise in global average temperature near Earth's surface. This steady rise in temperature is causing significant changes in weather and climate which is alarming because even small changes can create problems in our delicately balanced environment which will lead to challenges in our society. As a human race, we depend on the environment for fresh food, fresh water, and fresh air, so when there are complications with the balance of the environment, there are potential complications to our survival.…

    For the past couple of decades, researchers and scientists have gone head to head in attempting to figure out if global warming does exist. Some people argue against the point and some people may support it. The facts supporting human responsibility are there; however, some people do not tend to believe them, while others do. Professor Ian Pilmer, a geologist and professor of earth sciences, tries to convince people that nature is the main cause of global warming, and he uses his authority to create this false impression to force people into quick judgments. He also makes a hasty generalization in stating that “global warming and a high CO2 content bring prosperity and lengthen your life (Eggleton 171).” Pilmer thinks that just because the air people breath is made up of carbon dioxide and that it is good for one’s body, is a quick personal judgment. Llissa Ocko, on the other hand, who is a High Meadows Post-Doctoral Science Fellow at EDF gets straight to the point when she states that, “scientists are more confident than ever that humans are responsible (“How”).” Although many scientists are scholarly individuals, there exist so many different scientific viewpoints on the topic that it becomes difficult to know whom to believe.…
