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.
