CAROL COSTELLO (HOST): So Todd, I mean, do most voters really care about climate change? Are we just talking about this and people's eyes are glazing over? 

TODD GRAHAM: Yes, we care. No, our eyes aren't glazing over. Climate change is real. The science is out there. I mean, come on, it's the 21st century and we're way behind. We just had 180 countries sign the Paris Accords. We need to act on this and everyone knows it except for a small portion of Americans who are conservative -- but not just conservative, ultra-conservative, and they're not even honest about why. Now, Donald Trump's problem isn't that one tweet. He's consistently said he doesn't believe in climate change or that it’s human induced. So yeah, it's a real thing and you can't win a presidential debate by denying it. 
 
MICHAEL WARREN: Can I just say that I disagree strongly with that, that Americans really care about this. It's pretty low on the list of issues that people care about. I actually think in a weird way this is a winning issue for Donald Trump because the sort of preoccupation a lot of Democrats, and frankly a lot of the folks in the media, have with climate change as an issue seem really out-of-touch with terrorism, crime in the streets, the concerns about the police, and all these things we’re seeing as big issues. The problems of climate change I think have really gone down in the minds of voters and I don't think it will have that big of an impact.
