CBS News Poll - Eye on Earth: What do Americans think can be done on climate?

CBS News polling shows that Americans are concerned about climate change and most want it to be addressed right away, but what do people think can realistically be done about it? 

We asked Americans to weigh in on a few measures being proposed, asking specifically whether they think these goals are realistically achievable or not.  Public opinion is mixed, and views are shaped by political partisanship, as well as by broader views of climate change — the more urgent people think it is, the more optimistic they are about achieving these objectives.
