In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real? Is it man-made or is this just a natural cycle of earth? Does it really affect earth’s inhabitants? Should action be taken against it? If so, what kind and to what extent? It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life. This proves to be hazardous to the future of the planet; some people worry that many of the resources the environment provides that are taken for granted will not be available for future generations to utilize or protect. Many scientists now agree that humans largely influence the progression of global warming which in turn affects greenhouse gas levels, glaciers, storms, and the sea.
Firstly, the term global warming refers to the event in which the surface temperature of earth increases because of solar radiation trapped in the atmosphere. The sun’s radiation comes in the form of light waves which pass through the atmosphere and absorb into the earth and warm it, with the exception of a few waves bouncing off and reflecting back into space in the form of infrared radiation. Some of those infrared rays do not make it back to outer space because they get blocked by the atmosphere and descend back to earth’s surface. This is not necessarily a bad thing because it provides a comfortably warm and consistent climate; without these rays the planet would be freezing. The issue begins when an excess of greenhouse gasses from pollut...

The Pros and Cons of Global Warming Essay - Global warming, by definition is the “ 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.”(Webster) In the last several decades, there have been numerous debates regarding global warming. As of now it has become one of the biggest problems facing the world today. Scientists do believe that our production of greenhouse gases and carbon dioxide is having a warming effect on the atmosphere, but it also is creating a positive impact to on the planet....   [tags: Global Warming Essay]

Global Warming is Causing Climate Change Essay - Global warming is the increase in the earth’s atmospheric temperature. Naturally occurring gases such as carbon dioxide, methane, nitrous oxide, ozone and water vapor trap heat from the sun, preventing it from leaving the atmosphere. These naturally occurring gases along with human made hydro fluorocarbons (HFCs), per fluorocarbons (PFCs), and sulfur hexafluoride (SF6) are collectively known as greenhouse gases. This essay will explain why global warming is fast becoming a cause for concern and why preventative measures are being taken....   [tags: Global Warming Essays]

Global Warming: Humans Are Destroying the Planet Essay - Global warming is the gradual increase of temperature in the world’s atmosphere. It is often caused by high levels of carbon dioxide and other pollutants. It may also be increased by fossil fuels and agriculture causing many severe consequences, such as: species extinction, reduced forest and coral reefs, drought increases in Africa, severe flooding in Asia, threats to small islands because of ocean levels rising, and severe weather in hurricane zones. Our society today is destroying the climate....   [tags: Global Warming Essay]

Essay on Global Warming: Humans Are Destroying the World - In a century, various parts of the world will be underwater and there will be no life. Human activities such as burning fossil fuels, transportation emissions, and deforestation have caused global climate changes that can lead to catastrophic results if people do not take action. The main event that is contributing to Earth’s destruction is global warming. Global warming is a long term used to reference “a large increase in the Earth’s average surface tem temperature that results in large changes in climate.” Differences in “solar radiation, atmospheric chemistry, and oceanic and atmospheric circulation resulted in global climate changes.” Many human activities contribute to the much of the...   [tags: Global Warming Essay]

Essay on Global Warming: A Dangerous Reality - Global Warming has been a nuisance to environmentalists in recent years. It has been affecting Earth’s oceans, habitats, and biodiversity. Over the years, scientists have conducted experiments to understand the causes and effects of global warming and they have searched for solutions. They have warned others about the dangers of pollution and human activities and have urged others to do something about it. Films, such as Al Gore’s documentary “The Inconvenient Truth”, have also raised international public awareness of climate change and have re-energized the environmental protection movement; however, some politicians, government officials, and scientists have opposed this theory....   [tags: Global Warming Climate Change]

Essay about The Impact of Global Warming on Oceans - Water takes up a larger percentage of the surface of our Earth than does land. The earth’s oceans are vital aspects to our environment and it is necessary that we take care of them. On another note, global warming is an issue that is having effects on almost all aspects of our environment. Global warming itself means a gradual increase in the temperature of our Earth’s atmosphere over large periods of time. There is evidence that global warming has occurred in the atmosphere, however, now we are beginning to see its effects in the world’s oceans, as well....   [tags: Global Warming Climate Change]

The Effects of Global Warming Essay - The Effects of Global Warming What is global warming, and how is it affecting the Earth and its inhabitants. Global warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades....   [tags: Global Warming Climate Change]

Essay Global Warming and the Greenhouse Effect - Global Warming and the Greenhouse Effect      Recently, global warming has moved to a serious scientific issue. Because sunlight is constantly falling on the earth, the law of physics say that the planet has to radiate the same amount of energy back into space. Infrared radiation is sent out by the earth through the atmosphere, where molecules (carbon dioxide) hold outgoing radiation for a while, warming the surface.1 The molecules are kind of like glass in a greenhouse which is why this process of warming is called the greenhouse effect....   [tags: Environment Global Warming Climate Change] 1908 words

Global Warming Essay - Global Warming Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. (Melissa Phillips). This results in an increased emission of greenhouse gases. (Caroline Quatman). Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. (Brent C. Willhoite) Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases....   [tags: Environment Global Warming Climate Change]

Global Warming Essay - Global Warming Mission Plan a. Analysis of the Problem 1. History of the Problem      Some scientist's have been concerned since 1896 about what might happen if there were 5.5 billion tons carbon dioxide in our atmosphere. In 1961 a British scientist did an experiment showing that the carbon in the air was absorbing some of the sun's radiation. Afterward a Swedish scientist, Suante Arrhenius, found out if the radiation of the sun was trapped in the carbon dioxide the temperature of the earth would increase by 1-2 degrees....   [tags: Environment Global Warming Climate Change]
