A qucik and dirty cost benefit analysis of climate change
The guy in the video talks this up as a knock down argument for acting to mitigate and prevent climate change. It is far from that, but it is one of the strongest arguments you can pack into five minutes (plus four minutes of hype). I'm interested in it because it is exactly the kind of simplified cost benefit analysis I teach when I teach scientific reasoning with the Giere textbook. So I need to note it for the future when I figure out how to create a course that uses the Giere textbook at LCCC.

two points of scientific literacy
Some random parts of my scientific reasoning mid term. Questions are in bold. My answers are in regular font.
13. What are the basic elements of a Darwinian model of the origin of species?
Four point answer: Some reference to common descent
Five point answer: Common descent, random variation and natural selection.
Talking about finches will not help you here. Mentioning adaptation doesn’t help much either. Adaptation is only a part of the model in that it is something that is to be explained. Adaptation is observed, and then explained using random variation and selection. In philosophical terms, adaptation is the explanans, variation and selection are the explanandum.
18. Why are special creation theories marginal science?
Because they do not make any testable predictions. Three points off if you say because there is no evidence for them. The real problem is that the theories are not developed enough that there can be evidence for them.
