Geoengineering

Jeff Goodall quotes Ken Caldeira (via Brad DeLong):

“Thinking of geoengineering as a substitute for emissions reduction is analogous to saying, ‘Now that I’ve got the seatbelts on, I can just take my hands off the wheel and turn around and talk to people in the back seat.’ It’s crazy.”

Here's another analogy: geoengineering is like Nixon's price controls of the early 1970s. A sensible approach to galloping inflation is a monetary contraction in conjunction with temporary price controls. But imposing price controls without the monetary contraction gives you an explosion of inflation when the price controls are ultimately lifted.
