Jonathan Adler asks what it will take to convince libertarians and conservatives that climate change is a problem. Probably the recognition that man-made global warming does not mandate any particular policies. Of course, to a certain extent, libertarians and conservatives are entitled to be skeptical of the grounds used to justify certain policies. Golly gee, there's this problem which, arguable means, we must lose ever more liberty; and the people telling us all about this problem are, in large part, people who are always agitating for policies which result in loss of freedom, especially economic freedom.

Still, no policy position is mandated by acceding to the reality of climate change.
