Global warming fact or fiction Global warming fact or fiction Document Transcript

  • GLOBAL WARMING: FACT OR FICTION Global Warming: Fact or Fiction Victoria Rock AIU Online BUSN300-1202A-15
  • GLOBAL WARMING: FACT OR FICTION AbstractThis report will explore the topic of Global Warming in terms of fact or fiction surrounding theimpact on the environment worldwide. The purpose of this report is to inform members ofCongress about the two opposing viewpoints on this matter.
  • GLOBAL WARMING: FACT OR FICTION I. Background of Global Warming A. Impetus for the subject 1. Arguments for the topic 2. Arguments against the topic II. Discussion A. Melting Glaciers B. Unpredictable Weather III. Conclusion
  • GLOBAL WARMING: FACT OR FICTION I. Background of Global WarmingOne of the most debated topics on Earth is the issue of climate change or Global Warming.Global Warming fist became a concern in the 19th century when the industrialized revolutionfirst began. Scientist believe that the increase use of fossil fuels and deforestation has causedgreenhouse gases, which in turn has affected our climate temperatures. The National Oceanicand Atmospheric Administration, a national climatic data center, and the National EnvironmentalSatellite, Data, and Information Service (NESDIS) are central to answering some of the mostpressing global change questions that remain unresolved. A New York Times reporter said,“Global warming has become perhaps the most complicated issue facing world leaders (GlobalWarming & Climate Change, 2012)” The Natural Resources Defense Council says, “Climatechange is the single biggest environmental and humanitarian crisis of our time (Global Warming,2012).” In short, are we spending too much time, energy, and resources is assuring ourselvesthat global warming in deed an issue or is it merely a natural occurrence of nature in which wehave become more aware of due to our increase in knowledge? A. Impetus for the subject 1. Arguments for the topic The NOAA has said that the climate has warmed in some areas and cooled in others and the global surface temperatures tied 2005 as the warmest on record. (Global Warming: Frequently Asked Questions, 2012) Scientists feel that if we don’t reduce the emissions from the burning of fossil fuels and deforestation, the rise in the average temperatures will have far reaching effects on weather patterns, health issues, wildlife, glaciers, and sea levels. (The Consequences of Global Warming, 2008)
  • GLOBAL WARMING: FACT OR FICTION According to the EPA, the burning of fossil fuels and deforestation has caused the concentration of heat tapping “greenhouse gases” to increase significantly and these gases are preventing heat from escaping into space, much like the glass panels of a greenhouse. If greenhouse gases continue to increase, climate models predict that the average temperature at the Earths surface could increase from 3.2 to 7.2ºF above 1990 levels by the end of this century. Scientists are certain that human activities are changing the composition of the atmosphere, and that increasing the concentration of greenhouse gases will change the planets climate. But they are not sure by how much it will change, at what rate it will change, or what the exact effects will be. (The Consequences of Global Warming, 2008) 2. Arguments against the topic The main argument of the issue of global warming is the lack of scientific evidence linking the emissions of greenhouse gases as a result of human activity. British television producer Martin Durkin produced, The Great Global Warming Swindle (2007) in which he interviewed the scientist that was fist involved in the research of global warming as well as economists, politicians, and many others who are skeptical of the consensus of global warming. In this film evidence is shown that the earth is just going through natural changes which it has done for thousands of years and since the industrial revelation and increase in CO2 into the atmosphere, temperatures have actual deceased instead of increase. (Durkin, 2007)II. Discussion
  • GLOBAL WARMING: FACT OR FICTIONThe debate on global warming being fact or fiction is in fact a debate on what exact factorscontribute to the acceleration of the melting glaciers and the unexplained changes in weather.There is plenty of evidence to substantiate the fact that the glaciers are indeed melting morerapidly than a hundred years ago, and in many areas over the world weather has become moreand more unpredictable and violent. A. Melting Glaciers The Uppsala Glacier in Argentina is more than a thousand years old and is showing major evidence of melting while the Perito Moreno Glacier also in Argentina is thriving in defiance of the global climate change. Experts at the University of Alaska Fairbanks claim that due to increase in heavy precipitation in the area and strong cold winds, the glacier seems to be getting reinforced. (World’s 7 Largest Glaciers by Continent, 2009) B. Unpredictable weather Undeniably we have been experiencing extreme weather changes such as heat waves, droughts and killer storms like Katina which wiped out New Orleans. Isn’t this fact enough for us to look for solutions instead of laying blame on who or what is responsible? III. Conclusion The real issue is the identification of the economic impact of these changes we are seeing now due to global warming and what is yet to come. More importantly the need to implement policy changes in the way we run our governments and do business, not to combat global warming, but to ensure that our economies survive.
