In this week’ s must listen, Utah Senator Mitt Romney, who recently has left the door open to supporting a carbon tax, talked to KCPW radio host Roger McDonough about his views on climate change. Check out the interview (climate talk starts three minutes in and lasts until around the nine-minute mark) to hear why he hopes “climate change is significantly caused by human activity.” (Okay, here’s why: “Because if it’s not, there’s nothing we can do about it. So let’s hope we can have some influence.”)

Romney reiterates that he’s “looking at” the carbon tax and seems intrigued by the fact that oil and gas companies support the concept. “We are stewards of the earth and if we can make modest changes now… those are things we ought to do anyway.”

Related, this Letter to the Editor in the Deseret News thanks Romney for “taking positive steps on climate change.”

Way to go, EcoRight!
