  1. 1. What is it? What will it do? What can we do about it? Global Warming
  2. 2. What is Global Warming? <ul><li>An increase in the Earth’s atmospheric and oceanic temperatures due mostly to pollution </li></ul>
  3. 3. What Causes Global Warming? <ul><li>Greenhouse Gases </li></ul><ul><ul><li>Definition: Gases in the atmosphere that absorb and emit radiation </li></ul></ul><ul><ul><ul><li>some greenhouse gases are natural </li></ul></ul></ul><ul><ul><ul><ul><li>water vapor, carbon dioxide, methane, nitrous oxide, and ozone </li></ul></ul></ul></ul><ul><ul><ul><li>other greenhouse gases are manmade </li></ul></ul></ul><ul><ul><ul><ul><li>carbon dioxide, nitrous oxide, and methane </li></ul></ul></ul></ul><ul><ul><li>Manmade greenhouse gases result from burning waste, wood, and fossil fuels </li></ul></ul><ul><ul><li>We need some greenhouse gases to keep the Earth warm </li></ul></ul><ul><ul><li>Too many greenhouse gases, however, make the Earth HOT </li></ul></ul><ul><ul><ul><li>This is known as: THE GREENHOUSE EFFECT </li></ul></ul></ul>
  4. 4. The Greenhouse Effect
  5. 5. The ENHANCED Greenhouse Effect <ul><li>When too many greenhouse gases are present, less radiation from the sun is able to escape the Earth’s atmosphere </li></ul><ul><li>This causes the Earth’s temperature to increase </li></ul>
  6. 6. The Earth’s Rising Temperature <ul><li>According to StopGlobalWarming.com: </li></ul><ul><ul><li>Scientists commissioned by the United Nations have determined that global temperatures should increase by 1.1°C – 6.4°C over the next few decades. </li></ul></ul><ul><ul><li>The earth’s temperature has already increased 0.17°C every decade since 1978. </li></ul></ul><ul><ul><li>Several SRES scenarios were developed that took into account: population growth, economic activity, international co-operation, and the use of fossil fuels / renewable resources </li></ul></ul><ul><ul><ul><li>A1 : The A1 scenarios are of a world more integrated </li></ul></ul></ul><ul><ul><ul><li>A2 : The A2 scenarios are of a world more divided </li></ul></ul></ul><ul><ul><ul><li>B1 : The B1 scenarios are of a world more integrated, and more ecologically friendly </li></ul></ul></ul><ul><ul><ul><li>B2 : The B2 scenarios are of a world more divided, but more ecologically friendly </li></ul></ul></ul><ul><ul><li>All scenarios show a dangerous increase in temperature levels </li></ul></ul>
  7. 7. The Earth’s Rising Temperature
  8. 8. What Happens When the Temperatures Rise? <ul><li>Polar ice caps melt </li></ul><ul><li>Increased probability and intensity of droughts and heat waves </li></ul><ul><li>Warmer water and more hurricanes </li></ul><ul><li>Rise in sea levels </li></ul><ul><li>Massive crop failures </li></ul><ul><li>Extinction of plant and animal species </li></ul>
  9. 9. Polar Ice Caps from 2004-2007
  10. 10. Hurricane Katrina – The New Norm?
  11. 11. South Florida – Before and After Rising Sea Levels
  12. 12. How Can We Prevent These Atrocities? <ul><li>Recycling </li></ul><ul><li>Purchasing environmentally safe automobiles </li></ul><ul><li>Using minimal electricity </li></ul><ul><li>Reducing CO 2 emissions </li></ul><ul><li>Spreading the word on global warming </li></ul><ul><li>Cap and Trade Programs </li></ul><ul><li>Approving the Kyoto Protocol </li></ul>
