Steamboat Springs Climate change has not arisen as a significant campaign issue for 2008 yet, but I expect it will do so. It's been some time since I've written on the subject, and I would like to add a perspective that is seldom, if ever, mentioned.
CO2 is the focus of concern about man's impact on global climate change. Science does not support this view. Water is the main greenhouse gas; many times more important than CO2. In fact, anthropogenic CO2 is a trivial greenhouse gas. We make a big mistake by viewing CO2 as a pollutant. We should view it as essential to the feeding of the world's burgeoning population. CO2 is food!
We haven't heard from the Malthusians much since the '70s, but feeding the world's people is beginning to surface as a major concern again. I believe many of us will live to see the day when atmospheric enrichment with CO2 is sought, and the clean burning of fossil fuels will be applauded. We should be careful about spawning damaging, unintended consequences. Alarmism tends to drive us to overreaction and premature actions, a la the banning of DDT, which has resulted in the deaths of millions with malaria. It's something to think about.
