    • 1. Global Warming
    • 2. Agenda
      • What is Global Warming
      • Greenhouse effect interactivity
      • The Evidence
      • The Effects
      • How can you help?
    • 3. What is global warming ?
      • Global warming or climate change is the gradual increase of the average temperature of the Earth
      • The average temperature of the Earth's surface is around 59˚F or 13 ˚C.
      • Greenhouse Gases in the atmosphere hold in heat
          • Without these gases, the Earth’s surface temperature would drop to around 0 ˚F.
    • 4. The Atmosphere
      • The Earth is surrounded by a thin layer of gases
          • Oxygen
          • Carbon Dioxide
          • Nitrous Oxide
          • Methane
      Greenhouse gases
    • 5. Atmosphere
      • Supplies gases required for life
          • Oxygen
          • Carbon dioxide
      • Offers protection from the sun’s ultraviolet radiation
      • Helps control Earth’s temperature by trapping solar energy next to the surface
    • 6.  
    • 7. The Evidence Before and after pictures of Montana’s disappearing glaciers
    • 8. The Effects
      • Water levels will rise in oceans
      • The timing of the seasons will change
      • Increased spread of disease
      • Stronger hurricanes and storms
      • Animals change behavior
      • More plant and animal species will become extinct
      • Allergies get worse
    • 9. How can you help?
      • Use fluorescent lighting in your home
      • Drive a hybrid car
      • Use alternative energy sources for electricity and heat
      • Green roofs
    • 10. Green roof Back Back to TOC Next
    • 11. Endangered species
      • U.S. Fish and Wildlife Service Endangered Species List
      • Center for Biological Diversity
    • 12.
