Toward the end of the discussion, Roberto Denis of Sierra Pacific Resources says he cares deeply about the environment. But I'm left wondering whether he believes that global climate change exists and, if he does, whether he believes it is a serious environmental issue. We know he cares deeply about consumers and their ability to pay their power bills (to his company), but what about the economic impacts of climate change and the costs of inaction that will eventually be born by the same consumers? Does he care about those costs?
