‘Well, you’re arguing facts against opinions. OK, I mean, the fact that the amount of carbon dioxide in the air has rocketed up since the Industrial Revolution, and continues to rocket up, is a fact. Now, it’s so much a fact that even the climate change deniers look away from it and don’t deny it.’
— Professor Steve Jones, Feedback, BBC Radio 4, 18 October
Have a look at that last sentence. It represents such a cherishably stupid, rude, fatuous, crabby, bigoted, ignorant, petulant, feeble, fallacious, dishonest and misleading argument that if it turned out the speaker in question was a professor of logic or philosophy you really might want to shoot yourself in despair.
Can you see what the problem is? Let me explain. This angry professor character wants us to believe that there are people called ‘climate change deniers’ who are so far outside the pale of reasonable discourse that even when they are right it’s another sign of just how wrong they are.
Atmospheric CO2 has been rising since the Industrial Revolution, Jones is telling us, but those pesky deniers are so slippery that they refuse to deny this fact. If they did, presumably, it would make Jones’s job a lot easier because then he’d be able to provide a clear example of these wrong ‘opinions’ deniers supposedly hold. Apparently, though, Jones is unable to produce such a clear example. So instead he has to fabricate one and — in the very next breath — to discount it by conceding that actually this is a point on which ‘even’ the ‘deniers’ agree.
Am I being too harsh on Professor Jones? His field is genetics rather than atmospheric physics, so perhaps we shouldn’t be surprised if he sounds here like a rather desperate man flailing well beyond his pay grade.
