    Hannah Grecian
    Dan Valladares
  • Greenhouse Effect, Climate Change, and Global Warming
    Greenhouse Effect- When greenhouse gasses trap some of the Sun’s heat and light in the Earth’s atmosphere
    Climate Change- Seasonal changes in the climate over a long period of time
    Global Warming- Earth’s average temperature increasing gradually due to the greenhouse effect
  • How Global Warming, Climate Change, and the Greenhouse Effect are Related
    The Greenhouse Effect is a main cause of Global Warming
    Global Warming speeds up the Natural Climate Change process

  • Primary Causes of Global Warming
    Buildup of Carbon Dioxide in the atmosphere mainly from fossil fuel emissions
    Deforestation, because plants store carbon and when the plants are killed, it goes into the atmosphere
    Methane being released in various ways

  • Possible Consequences If We Do Not Work To Stop Global Warming
    Ice is melting worldwide
    Ecosystems will change
    Hurricanes and other storms may become stronger
    Sea levels rise faster
  • How Global Warming is Impacting the Economy
    Changing weather patterns make it difficult for farmers to grow crops reliably
    The crops they are able to grow will cost more to make up for their lower yield
    The public will have to pay more money for food
  • Several Ways to Fight Global Warming
    Replace light bulbs with compact fluorescent bulbs
    Drive less or choose efficient cars
    Buy energy efficient appliances
  • Basic Arguments Against Global Warming
    Climate Change is a natural process
    We can’t stop it and it would be a waste of money
    A small amount would be beneficial
  • Personal Opinions About Global Warming
    Global Warming should be take seriously by everyone
    It can harmfully affect the environment and the economy in many ways
    We should all try to do little things to stop it from getting increasingly worse
