  1. Greenhouse Effect—A Hot Topic Being One Member of This World We Must -- Face This Problem

  2. They are all killers of our Earth!

  3. We must do something to stop it!

  4. Members • Instructor: Elinor • Team Leader: Hsin-Chih Huang • Teammates: Rita Huang Angela Hung Pei-Chin Wu Yu-Hshan Guo Yi-ling Guo Yi-Ting Lin Yuan-Cih Chen Ming-Hong Siyu

  5. Contents • Motivation • Purpose • Information Coordination • Discussion • Conclusion • Suggestion • Reference

  6. Motivation The global warming hurts our lives seriously, shouldn't all of us understand and care about it? The global warming is about our earth and our environment. We all should do something for the place where we live.Save our earth—and save you and me!

  7. Purpose 1.To know the reasons why global warming happens. 2.To recognized the implements applied at present. 3.To understand the advantages and disadvantages after applying implements described above .

  8. Information Coordination The reasons why greenhouse effect happens: Many scientists and leaders contend that this happens when gases in the atmosphere– especially carbon dioxide,released by burning oil and other fuels – trap the sun's heat.

  9. Information Coordination The reasons why greenhouse effect happens: • Burning Power Plants • Cars 5. Buildings • Trucks 6. Methane • 4. Airplanes 7. Deforestation • 8. Carbon in Atmosphere and Ocean Some Living Example

  10. Information Coordination Some Living Example:

  11. Information Coordination Some Living Example:

  12. Information Coordination The implements applied at present: 1.Kyoto Accord 2. Framework Convention On Climate Change

  13. Information Coordination The implements applied at present: Kyoto Accord • ‧Industrialized countries which join the agreement • will going to do. • ‧The goal. • ‧The way to reach the goal.

  14. Information Coordination The implements applied at present: The Framework Convention On Climate Change ‧The ultimate objective. ‧Why should the level be achieved within a time-frame sufficient?

  15. Information Coordination The advantages and disadvantages of the implements described above: Advantages—They are reasonable limits to these countries. Disadvantages– Not all countries have joined the accord.

  16. Discussion 1.Being a junior high school student, what can we do? 2.Is the world really warming up? Is the warming really caused by the human activities? Should we worry about it?

  17. Discussion--1 Being a junior high school student, what can we do? 1.Take public transit whenever possible. 2.Do not turn the air conditioners on when the degree is under 25. 3.Use things which can recycle again and again. 4.Plant more trees.

  18. Discussion--2 Q:Is the world really warming up? Is the warming really caused by the human activities? And Should we worry about it? A: About these questions, there are two different thoughts, one of them is yes, but the other one is no. But according to the scientists, our Earth is really warming.

  19. Discussion--2 • Yes. It has become clear that the world is warming up slowly. According to the U.S. Environmental Protection Agency, the earth has warmed by about one degree Fahrenheit over the past100 years. • What is less clear is that what is causing global warming– and what we can or should do about it. Some believe the warming is simply part of the world’s natural climate cycle. If the warming is natural, then there may be little humans can do to stop it. We may just have to learn with warmer temperatures.

  20. Discussion--2 • No, our Earth is not warming up by human activities. As you can see, the Earth is still very lively, and the weather had changed since millions years ago. The ice age had came and gone for many times. There is no need to worry about our Earth. • If the Earth is really warming up, it is just because the Heat Island Effect, not the Carbon.

  21. Conclusion American writer Mark Twain once said, ‘‘Everybody talks about the weather, but nobody does anything about it.’’ Now, people really are trying to do something about it. Though we are just junior high students, we still can influence the people around us. From now on, we should do more to save our earth. It’s not difficult for us to do it. Just do it!
