More information will not change that. I've watched those people in Congress and their questioning of climate specialists. There's no amount of new information that will change their minds. I think it is an unholy influence of religion (Christ will save us), anti-Science (Science is some sort of dodge), economics (it will cost money to change), right-wingnut politics (if the left wants it, it must be bad), and finally, sheer ignorance (they never took a Science course they liked, and in most instances it appears they've never taken a Science course).
Congress is not a bunch of enlightened individuals. As individuals, they appear well-intentioned. However, put Klieg lights on them and their "questions" are really campaign points. And they usually have law backgrounds. That isn't bad in itself but they appear more intent on the form of an argument than on the basis for an argument. And then there is the lack of academic honesty: instead of admitting they do not know, they will accuse everyone else in the room of not knowing.
