I am aware that some of the concepts introduced in Part II are difficult. Species extinctions driven by human actions are easy to understand, but thermodynamic models relating energy and the global economy are very hard to understand.
I want to point out that humans, especially orthodox economists, are just as deluded as I said they are, a point which becomes easier to make when we consider Paul Krugman's Could Fighting Global Warming Be Cheap and Free? (hat tip, reader Reed).
This just in: Saving the planet would be cheap; it might even be free.
But will anyone believe the good news?
