Refuting the last few scientific arguments for denial is not going to bring conservatives around. Clever new ways of talking about climate action are not going to bring conservatives around.
Research on public opinion shows that conservative opinion is responsive to one thing above all else: the cues of conservative elites. People don’t have strong opinions on political “issues” one way or the other. They believe and do what people like them believe and do, and they take their cues on that from trusted tribal leaders.
To put it more simply, conservatives will tend to believe on climate change whatever people on Fox (or talk radio) tell them about climate change.
It is conservative elites, and only conservative elites, who have the power to end this surreal farce. Judging from Rush Limbaugh’s take on hurricanes, they do not yet feel any pressure to do so.
