Update: You will be able to watch a recording of the debate around August 24 on Youtube, the link that worked briefly has been taken down.
The debate I announced here between Steve Koonin and Andy Dessler took place Monday August 15th, it was very educational and illuminating. I will try and write more about it in a few days.
In short Andy Dessler said that economic models suggest that climate change is a negative for human civilization and not positive at all. But he avoided putting any numbers to this assertion.
Dessler believes that wind and solar produce electricity cheaper than fossil fuels, and that they can provide most of our power. Koonin counters that the only reason wind and solar are cheaper is that the cost of fossil fuel backup and the required changes to the U.S. grid are not included in the solar and wind costs. Koonin shows an estimate of $2.4 trillion to upgrade our electric grid to work with mostly wind and solar.
Koonin stated that the costs of climate change are minimal, and in 100 years will not be noticeable because the world economy will grow so much in that time. Climate change, even in the worse scenarios, only reduces economic growth very slightly, by 4% or less, and everyone will still be better off. He notes that in the past global warming and climate change have benefited mankind since people are much better off today, and much more resilient to climate change, than 100 years ago. He also points out that the poor of today should not be made to suffer because the elites (that is the U.S. and the western world) believe, without evidence and only based on models, that fossil fuels are polluting or dangerous. He adds that solar and wind are not pollution free.
Koonin quotes U.S. economist Anthony Downes, who once said:
“The elite’s environmental deterioration is often the common man’s improved standard of living.”
From “Up and down with ecology- the ‘issue attention cycle,’” by Anthony Downs (link)
Obviously Koonin won, the swing was 25% in his favor. Let us hope that these results are not changed online like they were in the last big climate change debate.
