Lindzen: “What happens if I get rid of about 60-65% of the CO₂ in the atmosphere? … We’ll die. We’ll die of starvation. At 160 parts per million, virtually no plant will survive. No plant survives, there’s no food.”
…
We hear it more and more nowadays. That there is now a 97 per cent consensus.
Oh, that’s fake! How should I put it? It always depends on the question. So, for instance, if you asked a question if doubling CO₂ is more likely to warm than to cool the Earth, I would think you’d get 100% agreement. But that’s not the same as saying it’s a serious problem. So, at that level, if you ask the right question and put a funny interpretation on the answer, you can say all scientists agree. You just haven’t said what they agree with.
In 1988, you had a Senate hearing in the US, and you had a man called James Hansen (US climatologist – HS) testifying. He came there and said that increasing CO₂ was going to cause a lot of warming. And Newsweek had a cover showing the Earth on fire, and it had a label: “All scientists agree”. And that was very interesting, because at that time, almost no scientists were working on this. People were told all scientists agree. Now, think of that from a propaganda point of view. You don’t know science, you haven’t studied it, most people haven’t studied it. Even among the people who studied the science, for this problem, a big part of the problem is fluid mechanics. Almost no physicist ever studies fluid mechanics. So you have something that hardly anyone has studied. And you’re saying: “What am I going to do? I don’t understand this.” You are told all scientists agree. This is a source of comfort. You don’t have to understand it. If all scientists agree, you can agree, too.
