Freeman Dyson has upset the green movement again, by reminding them that one of the world’s most renowned physicists is a climate skeptic.
According to Dyson;
What I would like to emphasize is that human actions have very large effects on the ecology, which have nothing to do with the climate. Carbon dioxide is what we’re producing in big quantities and putting into the atmosphere. This happens to be a very good fertilizer for all kinds of vegetation, good for wildlife, good for agricultural production, so it has many benefits. And this is something you have together with the climate effects, which are much less certain, so it’s a question of drawing a balance. I’m just saying I don’t understand it and neither does anybody else. I’m skeptical because I don’t think the science is at all clear, and unfortunately a lot of the experts really believe they understand it, and maybe have the wrong answer.
Of course [the weather] concerns me, but of course, we don’t know much about the causes of those things. We don’t even know for sure whether it is more variable than it used to be. I mean the worst disasters were the Ice Ages, and nobody really understands for sure the causes of Ice Ages, so I’m not saying the climate disasters aren’t real, I’m merely saying we don’t know how to prevent them.
The new book looks interesting. I haven’t read any Freeman Dyson books yet, but I’ve read some of Dyson’s blog posts. In my opinion he has a gift for explaining difficult concepts. The new book, Dreams of Earth and Sky, follows other popular Dyson books, The Scientist as a Rebel, and Disturbing the Universe.
