To me it's just obvious that there must be some truth about our environmental problems that is true for everyone, whether they're left- or right-wingers. There must be some truth that we could define together based on knowledge, and I wanted to know where this knowledge was. How much could we agree upon from the facts?

But all I saw was this arguing going on - it was like watching a house burn down while the fire brigade was arguing about how the fire brigade should be organized. I felt, "God! Couldn't we agree upon something, and see how much we could start doing on that basis?"
