“The current climate change is an outer mirror of our inner consciousness. It is an outer mirror of our attitude to try to conquer nature, instead of being in harmony with nature, but in the end the part can never conquer the whole.” - Swami Dhyan Giten. Climate change has been a common topic for discussion and debate in recent years. Many people question the idea of global warming and prefer to categorize it as a merely a theory. Whereas there are other individuals are certain about the effects and consequences of environmental pollution on the global climate. Although climate change is often seen as a theory, there are an abundance of facts to support its existence. Global warming or climate change is defined as, “a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.” Those against the idea of global warming will argued that this gradual increase in overall temperature is not solely attributed to the greenhouse effect but instead a natural warming cycle. Although this may be true, human activities do not elude blame for the drastic increase in global temperatures in the last century. In the earth's atmosphere has accumulated immense amounts toxic gases produced by motor vehicles (11,000 lbs of CO2 per vehicle) and the burning of fossil fuels (21.3 billion tonnes of CO2 per year), these toxic emissions are also to blame for acid rain which damages crops around the world. Ultraviolet rays omitted by the sun and deflected off of earth is unable exit the atmosphere due to this blanket of pollution. This phenomenon know as the greenhouse effect is responsible for climate chan... ... middle of paper ... ...we observe and recognize these changes as they do not solely impact the environment but also pose a huge risk to our health. In conclusion, global warming is not a theory but in fact a phenomenon. Steps must be taken in order to reduce environmental degradation that is caused by human activities, which continue to disrupt the earth’s natural cycles. People must put aside their own ignorance and inform themselves of the facts of climate change. If we continue to categorize climate change as a myth, there is no chance of returning the earth to its most prosperous for both the environment and all species including humans. The facts that support the existence of global warming are not concealed. Everyone is able to look outside and see the unpleasant change that the environment has undergone. http://www.who.int/mediacentre/factsheets/fs313/ http://www.wikipedia.com
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
Ever since the advent of weather observation and prediction technology in the past 150 years, science has created a consensus that the earth is getting warmer, and that human influence is to blame. Some even blame this change, known as global warming, for bouts of extreme weather including cyclonic storms, droughts, wildfires, and heat waves. These scientists (and much of the public) believe that our influence is the problem, as our emissions of carbon dioxide and other greenhouse gasses, the product of the usage of our fuels, are polluting the atmosphere and trapping energy from the sun within. However, a minority group, scientists and public skeptics alike, believe this warming trend is merely a coincidence with the earth’s naturally cyclical climate, and that the activists are overstating something they know little about. Many even agree that if the prospect of our influence were to be true, the effects are not at all that bad, unlike what it is hyped to be. Thus, global warming has become a debatable theory. Much like legislation that prevents schools from teaching evolution as anything more than a theory, now there are also laws that mandate that global warming be considered debatable, and to argue both sides of it (Jonas).
One of the main causes of climate change is the massive amounts of greenhouse gases, especially carbon dioxide that is being released into the air. This causes pollution in the air and, subsequently warms the Earth. By the end of the century, Earth is expected to raise about 2 degrees (Adams). The implications of a global pollution are potentially disastrous; industrialized cities and cities with high traffic are set for massive negative
Global warming is an increase of carbon dioxide, nitrous oxide and methane disrupting the earth’s ecosystem ultimately causing climate changes, this is just one of the tradeoffs of the modern life we live. Some doubt that global warming is a real issue despite the increasing natural disasters, freak weather and populations of species becoming extinct. Global warming is one of the challenges that we are facing today, it is much like the climate changes faced in the past but our climate is changing more rapidly. Wi...
Climate change, otherwise known as global warming, has grown more apparent in recent years, with increased natural disasters, significantly warmer temperatures and unreasonably long seasons. Global warming is one of the main concerns that scientists have been researching for the past century. Scientific evidence shows that global warming is caused by human behaviors. Due to the amount of human-induced carbon dioxide and other greenhouse gases that have been released into the air, the earth is becoming a highly poisonous place to live on. Earth’s climate has been constantly changing ever since the Industrial Revolution, when innovations began and factories were built, which emitted mass air pollution. As more technological advances continued the years after, the amount of carbon dioxide in the air also increased. According to the UPI Space Daily News, “Global emissions of carbon dioxide (CO2) - the main cause of global warming - increased by 45% between 1990 and 2010, and reached an all-time high of 33 billion tonnes in 2010” (Writers 1). The 1900s through the 2000s is the time period in which humans caused the most air pollution by creating vehicles and other industrial machinery. In the contemporary time period, human activities that contribute to climate change consist of hydraulic fracturing, rice cultivation, the increase of fossil fuel burning, and the rise of deforestation.
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.
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.
Climate change is an inevitable phenomenon that is being experienced globally in various forms, such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the fourth assessment report of the IPCC project, even with immediate implementation of mitigation strategies, global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damage in the future. It is estimated that global temperature will rise by 1.8 oC - 4.0 oC by the end of the 21st century (Izaurraade, 2009).

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...
The Earth’s average temperature has risen one and a half degrees over the past 100 years, and the temperature is expected to rise about .5 to 8.6 degrees. The small changes in temperature can cause a devastating effect on the planet 's climate and weather patterns. The predominant factors resulting in the warming of the earth are the emissions of CO2 and deforestation. CO2, which damages the ozone layer, comes from several sources, but the most problematic are those coming from the burning of fossil fuels from power plants. This releases thousands of tonnes of CO2 into the atmosphere every year. Another cause of these emissions is the burning of gasoline for transportation, which continues to increase because of our
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.
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
The planet Earth has seen a 1.4°F increase in global temperature since the 19th century; carbon dioxide concentration has increased by 40% since 1880, the highest in 800,000 years; sea ice in the Arctic is shrinking; sea levels have increased by eight inches thus far; and the ocean’s acidity is increasing. Global climate change is all too real. Global climate change is not a myth.
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”).
