  • 1. Global warming
    By: Billy Tascarella and Phil Bohner
  • 2. The greenhouse, climate, and global warming
    Greenhouse gases trap infrared radiation keeping the lower levels of the atmosphere hot and the upper ones cold.
    Climate change is a change in weather patterns and seasonal changes
    Global warming is the heating of the earth over a long period of time
  • 3. How there related
    Greenhouse gases trap heat in the atmosphere causing global warming
    Global warming then causes the climate changes
  • 4. What causes global warming?
    Global warming is a gradual increase in planet wide temperature caused by the greenhouse gases
  • 5. Consequences
    Weather patterns change
    Melting glaciers and rising sea levels
    Some wildlife could become extinct
  • 6. Impact on the economy
    We have to use less oil to try and stop global warming and that would cause a lot of people to lose jobs
    Extreme weather will impact our economy if we have to pay to clean up the aftermath
  • 7. Fighting global warming
    Don’t use as much water if u have to don’t use hot water use cold water
    Recycle and save energy
    Use less fossil fuels you could carpool or ride a bike or walk
  • 8. Against global warming
    Some scientist say that global warming is natural and the Earth tends to heat up or cool down every once in a while.
    Satellite imaging shows no signs of global warming
    Global climate computer models can not predict future climate changes
    global warming of a modest amount of global warming would benefit the Earth
  • 9. My opinion
    Billy's opinion
    I don’t think humans play a big part in global warming
    I think its natural
    Phil's opinion
    I think humans have something to do with it
    I believe it’s a combination of humans effect and earths natural heating
