Last week, two reports came out that look at how much it will cost to drastically reduce the pollution that causes global warming. Both used economic models to project how the growth rate would change. One used a realistic set of assumptions, and the other stacked the deck with extreme assumptions.
But both of them look at only one half of the real question. They ask “How much will it cost?” (Answer: Surprisingly little). But we also have to ask, “What do we get in return for that investment?”
