Another Prominent Dissenter: Physicist Dr. Glenn Marsch: ‘Trying to eviscerate our economy so that we can’t combat the much greater threat of cooling is one of the worst things we can do’
Dr. Glenn A. Marsch is a professor of physics at Grove City College where he teaches physics: 'What if they’re wrong and we’re actually about to embark on a period of global cooling? What if, in fact, the carbon dioxide we’re emitting is truly as potent a greenhouse gas as people say it is; and what if it’s keeping our temperatures relatively safer now and preventing them from plummeting? In that case, trying to eviscerate our economy so that we can’t combat the much greater threat of cooling is one of the worst things we can do. The problem with the precautionary principle is that on the basis of ignorance, it says that we must do something that could be deleterious. Rather than helping, we could be hurting when we can least afford it.'
I’m certainly not willing to say that all of it was due to human activity. I would suspect that little of it, maybe less than half of it, is due to human activity. The point is I’m not sure. There are a lot of uncertainties in this.
I’m also skeptical that this 0.6 oC temp increase is necessarily a bad thing. That’s why people often differentiate between AGW (anthropogenic global warning) and CAGW (catastrophic anthropogenic global warming). Even if people did cause the majority of global warming, I doubt that it’s harmful overall.
