So there is a very simple question, of course, with climate change. If you consider putting this amount of greenhouse gas into the atmosphere, Co2 and other gas, then does the climate react and, if so, how does it react? That’s obviously a sensible question to ask. The only way you can answer that is to make measurements and to model the climate as best you can. It’s the best you can do. What else can you do? You could read tea leaves and do tarot cards.
Science is never right. The power of science is it's the only human system of thought I can think of that accepts its own fallibility. The great Jacob Bronowski, in The Ascent of Man, said that. He said that this is - it’s the expression of our humanity because it’s the one discipline that understand its own fallibility, just like we are fallible. But that's the point. The point is that science is the best you can do at any given point. So you've got to act on it.
