"What I have discovered in 20 years of studying the universe, from here to there to everywhere, is that the universe is complicated, and when things happen, it is almost never like ‘A happened and therefore B’. No, A happened and therefore B, C, D and E, but then there is this thing F, and that had a 10% effect, and that prompted G to go back and tip over A, and it is always like this – everything is interconnected. And so a lot of these far-right fundamentalist religion people, and a lot of these people who are anti-global warming, anti-evolution, anti-science, what they do is they take advantage of the fact that things are complicated, and their lives are based on things being simple – if we do this, then this will happen – if we invade Iraq, we will be treated as liberators, if we pray, then good things will happen, and this stuff is wrong. But we have a culture where people are brought up to believe in simplicity, and if A then B. And so when you point out that scientists say the earth is warming, but we had a really devastating winter this year, then these people will say “oh, obviously global warming is wrong”. No, global warming can cause worse winters locally. It’s complicated. But people don’t want to hear “it’s complicated”, and boy, the conspiracy theorists and anti-scientists take full advantage of that."
