Jay Rosen at his PressThink blog examines the range of approaches different publications have taken in covering presidential candidates who are climate change deniers (AKA "Republicans") and offers some options:
1. Normalize it: treat denialist claims like any other campaign position. Here you simply say “the Senator doubts that climate change is really happening” and leave it at that, treating this as a normal position in a debate that carries on. You deal with a candidate’s denialism by not drawing any special attention to it. Just as some candidates think we need a fence at the southern border and others don’t, some think climate change is a myth or hoax and others do not. That’s politics! Advantage: It appears to be the most neutral way of handling the issue. And in a bitterly contested election neutral sounds awfully good. The problem: gross abandonment of the “checking” function that a free press is supposed to provide. It’s hard to feel good about that.
2. Savvy analysis: is denialism a winning move or is it costing the candidate? Here you go beyond stating “the Senator doubts that climate change is real” to look at the likely gain or loss in taking such a position. The risks and the rewards. What the polling says. Bracketing all questions of evidence — of truth — you focus instead on the smartness of the tactic. Advantage: you get to sound savvy and smart yourself, cool and analytical, not like those hotheads at Grist. Problem:Who cares if it’s true, let’s find out if it works! shatters the illusion that journalists can and do “hold their feet to the fire.” It’s hard to part with that.
3. Persistence: Call it what it is — a rejection of the science — and keep calling it that. “The Senator doubts that climate change is real, a position at stark odds with an overwhelming scientific consensus.” Here, you take responsibility for pointing out to voters that, while the candidate has his views, the evidence does not support them. And you do this not once, but every time the issue comes up. This is the fact-checking solution. Advantage: puts the campaign press back on the side of truthtelling. A major plus! Problem: likely to result in charges of bias from the candidates so described, likely to trigger the backfire effect among some voters (“in which corrections actually increase misperceptions among the group in question.”)
Senator, the Intergovernmental Panel on Climate Change said in 1990, “Emissions resulting from human activities are substantially increasing the atmospheric concentrations of greenhouse gases,” leading to global warming. They said it again in 1995. They said it again, but more strongly in 2001. They were even more emphatic in 2007. And in 2014 they said they were 95 percent certain that human action was the primary cause of global warming. The World Bank has come to similar conclusions. The position you have taken on this seems to suggest that you have better evidence than they do. Will you be making that evidence public? And may we have the names of your science advisors so we can ask them where they are getting their information? (Links.)
You can quarrel with the wording of my hypothetical press conference question but I hope you get the point. Actively confronting the candidate is a more aggressive way to go. Advantage: Fulfills the watchdog role of the press and says to politicians: there are limits, this is beyond the pale. Problem: Easily politicized, certain to trigger culture war attacks. Plus the backfire effect is likely to be even stronger.
What to do? All four paths have problems. In my view 2.) is the worst option, 1.) is not much better, 3.) is probably the best choice, but that doesn’t mean it will make a difference, and 4.) is the riskiest but might be a worth a try.
The fourth approach was pretty much how I operated as a journalist, but I have to say, I don't think it accomplished much. Officials would simply turn to a less aggressive journalist instead of dealing with me.
