Transcript of "Global Warming"

  1. 1. Global Warming (and Climate Change) dun dun dun…
  2. 2. How it happens: <ul><li>dun dun dun… </li></ul>
  3. 4. <ul><li>The Greenhouse Effect: greenhouse gases (carbon dioxide, methane, nitrous oxide, fluorocarbons) make the earth warmer by trapping energy in the atmosphere. </li></ul>
  4. 5. <ul><li>Global Warming: Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities. </li></ul>
  5. 6. http://epa.gov/climatechange/kids/gw.html <ul><li>Climate Change: Climate change represents a change in these long-term weather patterns. They can become warmer or colder. Annual amounts of rainfall or snowfall can increase or decrease. </li></ul>
  6. 7. THE COOLEST GUY EVER!: <ul><li>(ever!) </li></ul>
  7. 8. Al Gore! <ul><li>His film, based on his book, to raise awareness for Global Warming won an Academy Award! </li></ul>
  8. 9. The Kyoto Protocol <ul><li>The Kyoto Protocol called for a dramatic reduction of greenhouse gas emissions over a period of 5 years, between 2008 and 2012. </li></ul><ul><li>The Kyoto Protocol was adopted on December 11, 1997 and was put into effect on February 16, 2005. </li></ul><ul><li>The United States refused to ratify its participation in this treaty. </li></ul>
  9. 11. Some Vocab: <ul><li>Cap-and-trade system: sets an aggressive cap, or maximum limit, on emissions. Sources covered by the program then receive authorizations to emit in the form of emissions allowances, with the total amount of allowances limited by the cap. </li></ul><ul><li>Pollution Permits: companies have to pay a certain amount for the pollution they produce. </li></ul><ul><li>Gas Tax Suspension or Holiday: would reduce the tax on gasoline, for at least a little bit. Not a very good environmental idea because as soon as gas costs less more people will buy and use it. </li></ul>
  10. 12. Hillary Clinton <ul><li>The Good: </li></ul><ul><li>-A plan that proposes a cap-and-trade system that cuts greenhouse gas emissions levels from 1990 by 80% by 2050. </li></ul><ul><li>-The focus would be on efficiency and investment </li></ul><ul><li>-Also a National Energy Council to coordinate action across federal agencies. </li></ul><ul><li>The Bad: </li></ul><ul><li>-Calling for a suspension of the federal gas tax over the summer. </li></ul>
  11. 13. Barack Obama <ul><li>The Good: </li></ul><ul><ul><li>-Centers around a cap-and-trade that calls for an 80% emission reduction from 1990 levels by 2050. </li></ul></ul><ul><ul><li>- Also auctioning 100% of the pollution permits. </li></ul></ul><ul><ul><li>- The proposal also calls for a $150 billion investment plan to boost clean energy and create green jobs, proposals to boost efficiency, build a smart electricity grid, and encourage public transportation. </li></ul></ul><ul><ul><li>- Unlike Clinton he does not endorse the suspension from the gas tax. </li></ul></ul>
  12. 14. John McCain <ul><li>It’s Not Too Bad But Not Too Great: </li></ul><ul><ul><li>-His plan calls for a cap-and-trade system that would gradually reduce levels of greenhouse gases from 1990 by 60% by 2050. </li></ul></ul><ul><ul><li>-His plan would give away pollution permits instead of auctioning and give polluters much leeway to buy carbon offsets instead of reducing their own emissions. </li></ul></ul>
  13. 15. The Effects of Global Warming:
  14. 16. SAVE THE POLAR BEARS! Glacial retreat and disappearance!
  15. 17. And people say that global warming isn’t a problem…riiiiight….
  16. 18. Extreme Weather! <ul><li>i.e.: -increased hurricane power </li></ul><ul><li> -increased evaporation </li></ul><ul><li> -extreme temperature changes </li></ul>
  17. 19. And Ocean Levels Rising <ul><li>In the past 100 years global sea levels have rose 4-8 inches. </li></ul>
  18. 20. Oh…and this… Welll….maybe not exactly…
  19. 22. And the final slide: <ul><li>If action is not taken now, the earth we know will be gone forever! </li></ul><ul><li>The rising sea levels will cover amounts of land we now use, animals will become endangered and even extinct, and the entire balance of the planet will be ruined. </li></ul>
