The science is still out. I’m a Ph.D. scientist, and people say ‘well, you’re a skeptic’ and my answer is ‘well, all scientists are skeptics. That’s what being a scientist is.’ And, so when you hear a consensus saying ‘gee, we think this is a big problem,’ and then you actually look at the real science, and you find out, gosh, the temperature has not gone the way we predicted it would, we have to go back and ask ‘how are our assumptions doing? Are we really right?’ And when we’re talking about the size of investment we’re talking about, we need to have a great deal of confidence. What we have though are opportunities to make sensible changes. […] What we need to do in the final call is have a good public discussion about this. And, when you do, you find people are not willing to go any further than they have to because of the other expenses in life.
