Recommended: Carbon dioxide affecting our environment
Over the last century, predominantly in the last twenty years, the earth has endured unparalleled heating. A person’s first response might be why? Hasn’t global warming always existed? Yes. It has always been a menacing epidemic but there have been obvious changes to the environment. With the drastic weather changes, it is suspected that all of the polar ice sheets should be melted by 2100. Many scientists have studied what could be the cause of this epidemic. The fact of the matter is that the scientists have established what exactly is causing it, which are high levels of carbon dioxide. Global warming is life threatening and for the majority, caused by the human race and our technological advances.
A collection of scientific evidence specifies that… “since 1950, the world's climate has been warming, primarily as a result of emissions from unfettered burning of fossil fuels and the razing of tropical forests” (Science). With this motion enhances to the ether's unseen blanket of carbon dioxide and other earth-warming “greenhouse" gases. In recent studies research has revealed that “…methane, which flows from landfills, livestock and oil and gas facilities, is a close second to carbon dioxide in impact on the atmosphere” (Science).
The standard view on global warming is allocated in half, but the majority believes that global warming does exist, but it is not contrived or heightened by human activity. The problem with the standard view is that yes, there are other factors that have been known to amend the earths temperature, but it is obvious that pollutions that are only caused by advances in technology and human development are the leading cause. It is important to change the general view so there can be developments to cur...

...regressive and the earth will continue to heat but if we cut back on our use of technology and the development on new land we can decrease the earth’s temperature. Humans obviously have a hand in the increase of temperatures, but as previously stated events in the past with drastic climate changes have occurred. In the future there are bound to be dire changes to the climate. As humans we need to put more effort into advocating this cause by cutting back on our use of technology and destruction of nature.

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).
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
In the article “Counterpoint: Cooling Off” by Dr. Amy Witherbee, a Professor at University of Arkansas, she shares the concerning statistic “Carbon dioxide has increased 30%, methane has increased more than 100%, and nitrous oxide has increased about 15%” (Witherbee). This is concerning because these dangerous gases called greenhouse gases cause many problems and are a hazard to our planet. One of the biggest issues facing the world today is climate change; to address this issue, we must lower greenhouse gas levels and use cleaner energy sources.
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.
Furthermore, this analysis must take place amidst serious gaps in the existing research and technology concerning the developing climatic conditions. For these reasons, global warming stands as one of the most daunting policy issues facing our world today. This is compounded by the debate over the very existence of climate change. While countless sources of empirical evidence testify to the very real presence of climate change the world over, considerable denial of the phenomenon still exists. The argument has been made that evidence of climate change is a gross overstatement, or in some cases, a complete fabrication.
Nine of the eleventh hottest years in the 20th century have occurred since 1985 which is not consistent with a natural trend. Glacier Shrinkage is occurring at a much faster rate than can be explained by natural trends. Even when the heat effects of volcanoes and other misleading weather phenomena that would make the temperature of the earth seem higher than it actually is being taken out of consideration studies show that the surface temperature of the earth has been increasing at a rate of 0.17 degrees Celsius per decade. These figures are not consistent with a natural trend, and, when one considers the tens of thousand of years in which humans have inhabited the earth, and that humans have really only started burning fossil fuels heavily since the industrial revolution, and the fact that the world’s population is only going to increase, this number is dauntingly
The evidence clearly provided in this essay strongly supports the argument that greenhouse gases caused by air pollution are the main cause of anthropogenic climate change. The tables and graphs demonstrate just how greenhouse gases contribute to climate change. As is evident, climate change is an ever growing problem globally. Due to the increase in anthropogenic air pollution, greenhouse gases have amplified also, as shown by table 2. Figure one shows how carbon dioxide in the atmosphere has increased exponentially, mirrored by anthropogenic emissions of carbon dioxide. The various examples described clearly support the argument that greenhouse gases caused by air pollution are the major anthropogenic causes of climate change.
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
Background and Audience Relevance: There are always conversations about our planet. We see our earths glaciers melting, weather temperature rising, and pollution affecting our resources. But for some reasons we tend to look away. We should be more aware of this potential event and I’m here to inform everyone about what actually is global warming and the effects of it.
As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. Everyone in the world today is experiencing the effects of global warming. These effects might be small now, but if we don’t protect our planet now then the consequences will greatly be increased.
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors. I...
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”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
