Think, Read, and Write: Christy and Emanuel on Climate Change
By Amy Willis
This episode was recorded live at the University of Alabama, Huntsville, featuring two guests, both climate scientists, but with different views on what we know about climate change and what policies should be put in place, if any, to deal with it.
Here are some questions based on their conversation.
Please keep Econlib’s comment policy in mind.
1. In what ways is climate science like macroeconomics? How are climate models like economic models? How are they different?
2. Christy claims that the debate over climate change really entails a moral question, not a scientific one. What does he have in mind? To what extent do you agree?
3. In discussing temperature trends over the past ten to fifteen years, Roberts says, “one person’s eon is another person’s blink.” What does he mean by this, and how does it help illustrate the differences in the perspectives of the two guests?
4. Christy thinks the upper bound of the Emanuel’s temperature change forecast is unlikely to occur. How do you think he might justify that claim?
5. Emanuel concedes that current climate models are imperfect. How does he justify his predictions in the face of that imprecision? How does this influence the policy applications Emanuel thinks should follow?
