Strangelove Rides Again

The Economist has a short introduction to 'geo-engineering,' which I wrote about previously. When I heard James Lovelock speak some months ago, he voiced qualified support for Paul Crutzen's idea of spraying sulphates into the stratosphere to help counteract warming -- but not because it would get us out of our fix. Rather, he said, it might buy us time to restore the carbon balance. The Economist piece is very good. I especially appreciate the quote from the Carnegie Institute's Ken Caldeira, who says: "I started doing this work in an attempt to show that geo-engineering was a bad idea. I still think it's a bad idea, but every simulation we do seems to shows it could be made to work."
