There are three major camps, if you like, in the debate. There are what are often called the warmers: those are people who think that humans are changing the climate, and that this is dangerous. Then there are the lukewarmers: these are people that say that, well, it may well be that humans are having a significant effect on climate but it’s not dangerous. It’s either neutral or in fact it may be benign. It may be a good thing. It’s a good thing we got out of the little ice age, for example Pat Michaels, I have to mention, is a leading lukewarmer. In fact, I can plug his new book called lukewarming, which published by Cato quite recently. I recommend it highly. I am neither. I am a true skeptic. Although, it’s a little tricky because, ah, and this is where my, I guess my philosophical training comes in, it’s not a question of saying it’s humans are not affecting the climate. It’s more a matter of saying we don’t know what affect humans are having on the climate. In other words, it’s not a claim, it’s a concern. It’s an open question.
