All I'm doing, all I have done for 40 years, is spend time with the best scientific experts, gain their confidence, and take advantage of their patience in explaining things to me over and over again in progressively simpler language that I can understand, so that I can read it back to them and get their sign off, where they say, "Yep, that's it, Al. You've got it." When I understand it, I know I can explain it to other people. When the scientists' predictions end up being true, I see that as an opportunity to say to people, "Listen carefully to what they're saying now."
