Debate: Be it resolved that global warning is anthropogenic, not natural

This activity was developed during the Teaching Climate Change Using Ice Core Data workshop, held in June 2008.

Topic: Global Warming, torn between myth and facts


Course Type: introductory level or upper level

Description

This activity is a debate that will require students to defend strongly, their position, for or against, and be prepared to criticize the opposing view. The activity should come toward the end of the appropriate course and might be organized as follows:

  1. Choose the two sides by drawing straws. Defend position to the best of your ability, no ducking.
  2. Students will be expected to gather scientific data (e.g.from NOAA Paleoclimatology webpages) and read the appropriate texts (instructor may wish to restrict this to the last 400K years).
  3. Students will also be expected to read the major books of the skeptics and to make as strong an effort as possible to improve the skeptic's arguments.
  4. Proponents must behave according to the highest scientific principles and must admit what they do not know.
  5. Skeptics must use data published at any time in reputable journals but are allowed to lie by omission, but not in any other manner.
  6. Proponents do not know the rules that the skeptics are following. Skeptics do know the rules that the proponents are following.
  7. The debate will run as follows (for a 55 minute class; increase segments for longer classes or as needed; the instructor may or may not wish to arrange an audience)
    • Instructor gives overview and describes purpose.
    • Each group gives 2 minute summary of their position.
    • Each group gives 6 minute detailed presentation of their evidence and arguments proponents go first.
    • Each group gives 5 minutes for rebuttal.
    • Each group has 4 minutes for response.
    • Each group has 2 minutes for summary.
  8. During the next class session, the class as a whole, without taking sides, will discuss the outcomes of the debate. At this point, the instructor will reveal the hidden rules and discuss the debate.
  9. If possible, arrange for a real scientist and a skeptic to have a similar debate in front of the class.
