From the March 9 edition of CNBC's Squawk Box:
JOE KERNEN (HOST): Let me ask you this, let me ask you one other thing, just to get to the nitty gritty. Do you believe that it’s been proven that CO2 is the primary control knob for climate? Do you believe that?
SCOTT PRUITT (EPA ADMINISTRATOR): No, I think that measuring with precision human activity on the climate is something very challenging to do, and there’s tremendous disagreement about the degree of impact. So, no, I would not agree that’s a primary contributor to the global warming that we see. But we don’t know that yet, as far as -- we need to continue debate -- continue the review and analysis.
KERNEN: It’s, it’s a -- I agree. When I hear “the science is settled,” it’s like I never heard that science actually got to a point where it was – that’s the whole point of science is that you keep asking questions, you keep asking questions. But I don’t want to be called a denier, so it scares me. It’s a terrible thing to be called. Anyway, administrator Pruitt, I know you don’t want to be called that either. Thanks for being with us this morning I appreciate it.
PRUITT: Thank you very much.
