I think there’s an underlying psychology that each climate change denier displays. It is composed of classic anti-intellectual distrust of expertise and an over-amplified belief in intuition over data and evidence. This results in a huge range of conspiratorial thinking grounded in a devaluing of reason and evidence as good epistemology.
Facebook and to a lesser degree Twitter are two of the few avenues I’ve found that actually lets those of us who promote critical thinking, punch some holes in the confirmatory echo-chambers within which most science deniers live.
For example, a couple of times lately I’ve seen statements to the effect of, “the climate has changed in the past” as if that somehow obviates the fact that humans are causing the current change:
I’ve blurred Brad’s face and picture because he’s an old friend of mine but Twitter is an open forum so I’ve left that profile unobscured:
That the climate has changed before does not mean that humans haven’t pumped enough CO2 in to the atmosphere over the last century to cause more heat to be trapped (the Greenhouse Effect) which in turn causes the global mean temperature to rise (global warming) which in turn causes the climate to change. This is not a difficult concept.
But nothing beats a face-to-face “intervention.”
Happy critical thinking!
