More conversions on global warming
As CT commenters pointed out on my last post, there’s a rush of former sceptics announcing their change of views on global warming. Here’s Gregg Easterbrook and John Tierney. Ron Bailey, who changed his view on the science last year, has now taken the next step, observing that the economic costs of Kyoto are likely to be modest. Meanwhile, the Howard government’s push for nuclear power has turned a hitherto lukewarm endorsement of the science on global warming into positive enthusiasm on the topic.
But we haven’t seen much movement yet from the many local pundits who’ve spent the last few years denying the evidence on global warming and attacking those who presented that evidence.
For some, of course, credibility doesn’t matter. Like PP McGuinness, they’ll jump on to the nuclear bandwagon without ever admitting they were wrong about global warming. But I’d hope for something better from, say, Michael Duffy, who claims to be an advocate of reason, but has enthusiastically promoted climate contrarianism.
