April 8, 2010 -- “When the facts change, I change my mind. What do you do, sir?” Attributed to economist J.M. Keynes, that retort has always been good advice. Now that carrying on with “business as usual” greenhouse gas emissions has been revealed as a road to disaster, should environmentalists change their minds on nuclear power?
To be sure, the dangers of the nuclear industry have not gone away. A major nuclear war, by creating “nuclear winter” conditions, would end most life on Earth. Humanity, however, has managed the threat of nuclear war in the past, and the chances are that we will continue to do so.
If thousands of nuclear power reactors were in operation, reactor accidents would be frequent enough that they would almost stop being news. But deaths would probably be few, and other losses would be relatively minor compared to the dead oceans and scorched grainlands of the greenhouse future.
