(R) The US National Academies of Science, the National Aeronautics and Space Administration (NASA), and the National Oceanic and Atmospheric Administration (NOAA), and many others, say that climate is changing because of the human activities, and others do not agree with that. The Heartland Institute, the Heritage Foundation, and the American Association of Petroleum Geologists, and many others, argue that the gas emissions produced by people are too small to change the climate.

Scientists cannot come to a conclusion, if global warming is a cause of actions of humanity or is consequence of natural internal and external forcing mechanisms, such as solar output, ocean variability, volcanism and others.
(Argument)
(R) There are many arguments supporting the point of view that climate change is human activity consequence. (E) According to NASA: “75% of the 20th century increase in the atmospheric greenhouse gas CO2 is directly caused by human actions like burning fossil fuels. CO2 levels were 389ppm (parts per million) as of Apr. 2010 - the highest they have been in the past 650,000 years.” (C) As far as CO2 absorbs heat, and it’s amount produced by people rises, it can be a causation of global warming.
(E) Intergovernmental Panel on Climate Change reported that: “Human produced greenhouse gases will continue to accumulate in the atmosphere causing climate change because the earth's forests, oceans, and other "carbon sinks" cannot adequately absorb them all. As of 2009, these carbon sinks were only absorbing about 50% of human-produced CO2. The other 50% is accumulating in the atmosphere.” (R) People continue to destroy the forests for wood, (IC) so trees will absorb less and less CO2 in the future, this can lead to huge increase of CO2 in the
Since measurements began in 1958 -- and it can be assumed to have been the case since the industrial revolution -- emission of carbon dioxide into the atmosphere has risen steadily as a result of the burning of fossil fuels (Quay, pp 2344). Although there is much argument over the implications of increasing carbon dioxide levels in the atmosphere, there are several points that almost all scientists would agree on: firstly, carbon dioxide acts to absorb radiated heat; if present in our atmosphere will do just that to some extent. Second, the concentration of carbon dioxide in our atmosphere is rising. Third, the temperature of the planet is rising - although the amount of this increase and the causes of this rise are subject to disagreement (Philander, pp 193).
Today, some scientists are skeptical about the consensus on climate change. This can be compared to a situation in ancient times, where the majority of people believed the earth was flat, and only a minority dared to question that consensus. These challengers note that something not known is how much does the earth’s atmosphere respond to added carbon dioxide (McNider and Christy). This means that no one has any idea of what CO2 levels did to the earth’s climate before meaningful history. So, as many sci...
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
So what is the big deal? The problem, and the reason why this concept instills fear directly into the core of scientists, is the rate at which, over the past 1,300 years, atmospheric carbon dioxide levels have risen. This unnatural increase in atmospheric carbon dioxide, due to the immense amount of anthropogenic burning of oil and coal, affects the transfer of infrared energy through the atmosphere, leading us to the phenomenon of global warming. 1). 61). The aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid afore Moreover, it can also be seen “as presenting us with the largest collective action problem that humanity has ever faced, one that has both intra- and inter-generational dimensions” (Jamieson pg. 61).
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted
In recent years, climate change has been a controversial topic. Many people, including country leaders argue that the change is real and irreversible, while others claim it is a tactic to envoke fear among people. Climate change is defined as, “a change in the typical or average weather of a region or city” (nasa). Their is remarkable evidence for both sides of the debate which raises the arguable question, is climate change real? In this essay, I will explain both arguments of the topic about the controversy that surrounds climate change. For argumentative paper you must also develop your own position and defend your point of view on this topic. In your intro please provide a clear thesis statement.
Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57% of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver, 2009).
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Even if the reason of climate change may be the natural cycles, we humans are the major determinant to it. The huge amount of greenhouse gases in the atmosphere is causing the climate change and this amount is rising day by day, as a result of our actions. Greenhouse gases, like carbon dioxide, generally absorb and emit the heat in the atmosphere to keep the Earth’s climate habitable. However, as we continue to burn fossil fuels, this habitable Earth’s temperature will blow up, and as a result, some species will die out due to various problems which are caused by climate change. According to EPA (Environmental Protection Agency), the most obvious consequence of climate change is the rising sea levels, which will cause some seashore habitats to become unavailable to live to its species.
Climate change is one of the most discussed topics of the twenty-first century. Although this subject is very often on the daily basis of lots of people, most of them do not know much about it. So let us define climate change. People think that climate change is the same thing as global warming. However, global warming only represents one aspect of climate that is temperature. Climate change is any significant change in temperature, precipitation, or a wind pattern that occur over several decades or longer.
The Earth is currently locked in perpetuating spiral of climate change. While the global climate has unarguably been changing since the dawn of it's manifestation, the once steadied ebb and flow of climate change has become increasingly more unpredictable.The risk of rising sea levels, and drought plaguing the fresh water supply, during the time that flooding and sporadic storm conditions turn once fully inhabited regions into uninhabitable death traps. Climate change catalyzed by human's increased production of carbon dioxide, is more noticeable than ever in our recorded history (United States, 2014 National Climate Assessment). Thankfully however, with the changing weather conditions due to carbon related emissions, the change in public opinion about their personalized influence on climate change is also increasing. Kevin Liptak Jethro Mullen, and Tom Cohen note that In reaction to the most recent governmental report on climate change, even the U.S. government believes that a stronger approach needs to be taken to correct our self-generated cataclysm.
In the modern era, climate change is a variation of weather over a long period of time, and it is the most important and controversial global issue. It is arguable in different positions, especially on science, culture, and politics. These three fields all cause a lot of latent concerns. The science of climate change brings out several harmful phenomenon, such as global warming. With respect to the climate change, the culture of humanity may be changed because the changing climate is the most important key factor of forming today’s human societies. Instead, climate change is now a political issue, which will affect the public attitudes directly. In other words, it means the government tends to review and provide latest information in order to adapt and retard the climate change. Over a long period of time, climate change has been taking place because of human activities that affect the scientific, cultural, and political sides.
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
