Global Warming Essay - 932 Words

Global Warming When one starts a car or burns wood, the last thought on their mind is the consequences to these actions. Unfortunately, the daily dangers to earth are not widely known. Due to the constant change of society, this planet must cope with various problems. One of the most important ecological structures is the ozone layer. The same shield that protects us from the suns deadly radiation, can also act as a blanket engulfing us in heat. This situation is know as the greenhouse effect. Greenhouse gases cause global warming. What causes the greenhouse effect and what can be done to reduce global warming? The problem of global warming has been around for some time now. Though not until recently has it become a†¦show more content†¦This process is not new. In fact, without the greenhouse effect, the average surface temperature of the earth would be about 59 Fahrenheit degrees lower than it is today. Long before civilization intervened , the thin blanket of gases that surround the earth was efficiently trapping a tiny portion of the sun?s heat and keeping it near the surface to warm up the air just enough to prevent temperatures from plunging to frigid extremes every night- which, of course, is exactly what happens on the moon and on planets like Mars that have very thin atmospheres (Gore, 1992). The greenhouse effect received its name because the atmosphere of the earth acts much like the glass roof on a greenhouse. Sunlight enters the greenhouse through the glass as it heats up the plants. Then, the warmth is trapped as the glass slows the withdraw of heat. Similarly, the earth?s atmosphere lets most of the sun?s light enter and heat the surface. The earth then sends this energy, called Infrared Radiation, back into the atmosphere (showed in the diagram on page 7). This is when the actual effect takes place. Not all of the Infrared Radiation is sent freely into space. Certain gases in the atmosphere absorb it and send it back toward earth. Such gases are Carbon Dioxide, Ozone, and water vapor. As stated earlier, this process becoming more important.

There are extremists who do everything possible to stop contributing to the warming, but the average person does little to alleviate the issue and in many cases refuses to acknowledge that there is a problem at all. Dating back to millions of years ago, even before humanity was born, the world has always experienced one form or another of warming; so the warming seen today is not as bizarre as many mayRead MoreGlobal Warming And The Warming1353 Words   |  6 PagesGlobal Warming With it being the presidential election season the talk of global warming, also known as climate change has come up in conversation more. But should it be associated with whether you are republican or democrat? Global warming should not be rather you â€Å"believe† in because it is a stated fact. The definition by Oxford Dictionary declares that global warming is a gradual increase in the overall temperature of the earth s atmosphere generally attributed to the greenhouse effect causedRead MoreThe Warming And Global Warming1442 Words   |  6 PagesThe Warming World Around Us The world is warming and we cannot deny it, the longer we deny the larger the problem it will become. Global warming is affecting the world economy, the overall health of the population, and most importantly the environment that surrounds us. Ignoring this problem will not just make it suddenly disappear; the world has to make an effort to stop it while it can still be maintained. Accepting the fact that it is happening is just the first step, the next step is takingRead MoreGlobal Warming1677 Words   |  7 PagesThrough the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since theRead MoreGlobal Warming1410 Words   |  6 PagesGlobal warming was first mentioned by ‘Svante August Arrhenius in 1896’, but in ‘1753, Joseph Black discovered carbon dioxide’ and in ‘1827, Jean-Batiste Fourier suggested that atmospheric effect kept the earth warmer than it would otherwise be’, (Direct.gov. n.d. A history of climate change). Since this time, reports, and study have be done with graphs to show the impact of global warming and what could happen to our planet. In 1979, the first conference was held this was called ‘International climateRead MoreGlobal Warming1245 Words   |  5 PagesGlobal Warming The major threat of today’s world is global warming. Due to various reasons global warming turns out to be a serious issue in the last few years. Today people believe in global warming while this concept was not so much believed and people interpreted in some other meanings what was happening in the past. Global warming is amplification in the temperature of earth because of industrial pollution, fossil fuels, and agricultural practices caused by human being, other and natural gasRead MoreGlobal Warming1316 Words   |  6 PagesControversy over Global Warming One of the largest argued topics in our world today is over global warming. People argue that is real, and others argue that it is fake. The effects of global warming create a growing danger for the ecosystem we live in by damaging glaciers and weather patterns. Humans contribute to global warming yet non-believers will think otherwise. Global warming is the greatest challenge facing our planet. According to the IPCC (Intergovernmental Panel of Climate Change) mostRead Moreglobal warming1539 Words   |  7 Pagesof global climate over long periods of time. Climate model projections made by the US Intergovernmental Panel on Climate Change (IPCC) show that, recently, global temperature has increased. This increase in temperature is referred to as global warming. One of the main causes of global warming is greenhouse gases. Greenhouse gases are gases in the atmosphere that absorb solar radiation to keep the planet warm. These gases have increased, so more solar radiation is trapped ins ide raising global temperaturesRead MoreGlobal Warming1050 Words   |  5 PagesTake a position: Global warming is a real problem. 1000 word Essay. Using persuasive technique Global warming is the increase in the average temperature of Earth’s surface. Since the late 1800’s, the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8degree C). Climate change is happening and its effects are real. However, the larger the change in climate, the more negative the consequences will become.

Personally I don’t care very much about global warming and have never been active in green movements. The evidence presented in this class is very informative and useful when taking into account the numerous known and unknown causes and cures for global warming. However, my attitude towards global warming is unchanged. According to the Common Attitudes Toward Global Warming handout I think
