What do the moon landing and climate change have in common? They’re both fake. Well, at least if you belong to a certain small but very vocal group of people. As a part of this group, you might also be convinced that 9/11 was an inside job, that the CIA killed Martin Luther King and, yes, that radical free market policies will cure all the world’s ills.

Climate change deniers tend to be also conspiracy theorists and hard core free market ideologues, a new study finds. Apparently climate change denial very often goes together with the usual host of other fringe convictions and opinions. The reason for this, the climate science psychologist Adam Corner speculates in the Guardian could be

“…that it is the libertarian instinct to stick two fingers up at the mainstream – whatever the issue – that is important. Because a radical libertarian streak is the hallmark of free-market economics, and because free market views are popular on the political right, this is where climate change scepticism is most likely to be found.”

So what’s the solution? Corner suggests that

“the challenge of engaging with climate change sceptics is finding the lens that better fits their ideological views – not just shouting the science more loudly.”

Or maybe climate change has to be turned into a rogue topic – censored in the news, blasted by scientists, decried by the public – before it gains acceptance – among deniers. But then again, there is no such thing.
