Libertarian law prof. Jonathan Adler has a brief but interesting post up at the Volokh Conspiracy blog, explaining something of the internal conflict he faces in favoring limited government but acknowledging that it is likely that man is pushing the climate in ways that generates costs that merit concern:

Great post, Jon. I think that there are many Austrians who understand WHY there might be a climate change problem to which man contributes, as the atmosphere is an open-access resource, in which there are no clear or enforceable property rights that rein in externalities or that give parties with differing preferences an ability to engage in meaingful transactions that reflect those preferences.
But, flawed human beings that we are, we have difficulty truly keeping our minds open (subconscious dismissal of inconsistent data is a cognitive rule) and we easily fall into tribal modes of conflict that provide us with great satisfaction in disagreeing with those evil "others" while circling the wagons (and counting coup) with our brothers in arms.
Sadly, this is very much in evidence in the thread to your own post.
