The Candidates on Climate Change: Unspoken but not Unclear

As noted by many others, climate change was MIA at the presidential debates and, to a large degree, throughout the election season.  So let's ask the two key questions and let their (past) words speak for themselves: 

What causes climate change?

Obama:
September 2012, Charlotte, NC: “My [energy] plan will continue to reduce the carbon pollution that is heating our planet - because climate change is not a hoax.”

Romney:
October 2011, Pittsburgh, PA:  “My view is that we don't know what's causing climate change on this planet.”

Do you support US policies to reduce carbon emissions?

Obama:
November 2011, Canberra, Australia: “As we move forward over the next several years, my hope is, is that the United States, as one of several countries with a big carbon footprint, can find further ways to reduce our carbon emissions,”

Romney:
November 2011, Manchester, NH: “Now I know there is also a movement to say that carbon dioxide should be... managed by the Environmental Protection Agency. I disagree with that. I exhale carbon dioxide. I don’t want those guys following me around with a meter to see if I’m breathing too hard.”
