Shortcut To Catastrophe

By George Monbiot, AlterNet. Posted September 1, 2006.

A prominent scientist's idea to re-engineer the atmosphere in order to cool the earth could be as dangerous as climate change.

Challenging a Nobel laureate over a matter of science is not something you do lightly. I have hesitated and backed off, read and re-read his paper, but now I believe I can state with confidence that Paul Crutzen, winner of the 1995 prize for chemistry, has overlooked a critical scientific issue.

Crutzen is, as you would expect, a brilliant man. He was one of the atmospheric chemists who worked out how high-level ozone is formed and destroyed. He knows more than almost anyone about the impacts of pollutants in the atmosphere. This is what makes his omission so odd.
