Megan McCardle channels Jonathan Adler on the politics of global warming. I agree with McCardle and New Jersy Governor Chris Christie in taking a more nuanced approach. Human activity has probably contributed to global warming but the extent of the effect and prognosis for the future is unclear, but unlikely to be anywhere near the Gorean nightmare. Many of the proposals to combat warming cannot be justified on the basis of their costs and benefits.
Of course, that's hard to translate into partisan politics and sometimes I think the obstinence of the right is caused by the fascism of the left in which no discussion of the facts or the desirability of remedy is regarded as legitimate. But the real problem, as McCardle points out, is choosing facts to fit a predetermined position.
Being honest about the facts doesn't mean that we'll all agree or that the "middle" view is always correct. Reasonable people disagree about the facts and is that disagreement - and not someone's moral character or self interest - that makes for political disagreement.
