“When it’s a consensus among the uninformed, it’s not worth much“:
What can we take away from all this? First, lots of people get called “climate experts” and contribute to the appearance of consensus, without necessarily being knowledgeable about core issues. A consensus among the misinformed is not worth much.
Second, it is obvious that the “97 per cent” mantra is untrue. The underlying issues are so complex it is ludicrous to expect unanimity. The near 50/50 split among AMS members on the role of greenhouse gases is a much more accurate picture of the situation. The phony claim of 97 per cent consensus is mere political rhetoric aimed at stifling debate and intimidating people into silence.
Yes. Anyone who cites that number at this point is either a liar or appallingly ignorant.

Related, I was going to post about this interview with Jerry Taylor, formerly of Cato, who seems to aspire to be continually out of synch with reality:
I began to change, maybe five or six years ago, for several reasons.
One, the scientific evidence became stronger and stronger over time. A lot of conservatives think of climate change as similar to the population issue. You have to remember, in the ’60s and ’70s people were frantic about population growth. And it just peeled away as an issue, simply because it was wrong — or the projections were. And so I would say the same thing: [climate change] is just one in the endless parade of environmental apocalypse stories.
That’s simply not true. The scientific evidence has not become “stronger and stronger over time.” In fact, particularly with the pause, and the complete failure of the models, the uncertainty is growing.
Judith Curry addresses it:
…it is interesting to see Libertarian arguments about climate change policy they [sic] don’t seem overly caught up in the UNFCCC/IPCC ideology, or its antithesis ideology. The Climate Hawks (e.g. Dave Roberts) love this kind of libertarian ‘conversion’ story. But to my mind, Jerry Taylor’s argument for a carbon tax doesn’t really hold up.
Nope.
