Bill Nye the Science Guy and Tucker Carlson debate climate change, climate change "deniers," and what the world would look like without the impact of human activity.
TUCKER CARLSON: Bill Nye the Science Guy is now aspiring to a new title: Bill Nye the Psychoanalyst Guy. During a Facebook Like event with Senator Bernie Sanders today, the mechanical engineer and TV personality said, "Skeptics of global warming suffer from the psychological delusion of cognitive dissonance." It's a slight bump up from last year when he was open to the idea of imprisioning skeptics of global warming as war criminals. Is that the choice? Bellevue or Nuremberg? Bill Nye joins us now. Bill, it's great to see you. That doesn't sound like science to me, Bill Nye the Science Guy. That sounds like something very different.
BILL NYE: Cognitive dissonance is not an delusion; it's a feature. It's human nature. We in the science community are looking for an explanation why climate change deniers or extreme skeptics do not accept the overwhelming scientific evidence for climate change. And the most reasonable explanation is you have a worldview and then you have evidence and the evidence disagrees with their worldview so you deny the evidence, and along with that you deny the authorities that are providing the evidence. If you have a better hypothesis for why climate deniers deny the overwhelming scientific evidence, bring it on. It is not a delusion. It's just like the fox and the grapes. He can't reach the grapes so he says the grapes are no good.
CARLSON: People do come to every debate with preconceptions. You're right about that of course. But the essence of science is extreme skepticism. We always ought to be asking ourselves, "Is our hypothesis true?
NYE: Climate change denial is denial. The evidence is overwhelming. Don't get me wrong. I love you as a person more than life itself, but the evidence for climate change is overwhelming. So we are looking for an explanation for why you guys are having so much trouble with it.
CARLSON: Slow down before the name calling begins and before you try to end a conversation, let's start it by asking what exactly you mean. I think most people are open to the idea that the climate is changing. It's always changed, as you know.
NYE: It's the rate, Mr. Carlson, it's the rate that is such a concern.
CARLSON: The core question from what I can tell is why the change? Is it part of the endless cycle of climate change or is human activity causing it. That seems to be the debate to me and it seems an open question, not a settled question, to what degree is human activity is causing that. Is that not an open question?
NYE: It's not an open question. It's a settled questions. Human activity is causing climate change.
CARLSON: To what degree?
NYE: To a degree that it's a very serious problem in the next few decades.
Watch the rest of the video for more back-and-forth "conversation." It includes talk of jailing climate skeptics and an inordinate fascination with grapes.
