One last observation on George Will, the Washington Post and climate change. Beyond the scientific questions involved (is the aggregate area of polar ice decreasing due to climate change, what are the implications of that, etc.) the Will piece raises a broader issue: how much credence should media outlets give to columnists or others who deny anthropogenic climate change is occurring?
Obviously, the people who run the Post editorial pages should not lend their platform to discredited arguments (hold the snark, please). But this is a tougher question than it seems on the surface. Has man-made climate change now entered the realm of universal scientific acceptance, like evolution, quantum mechanics, or the notion that the earth orbits the sun and not vice-versa? Almost, but not exactly. There is an overwhelming consensus among scientists who have studied the issue. But that’s not the same as universal acceptance.
Also, since climate science involves computer modeling of very complex systems, it’s inexact. “Climate change” and “global warming” are themselves vague terms. The future – not just temperatures but sea levels, impacts on agriculture, changes in local living conditions and political stability – is very hard to predict. The policy options are numerous. This pocked terrain means there’s plenty of room for debate on the nature and impacts of climate change and the science used to assess those things. Some think the problem is overhyped by Al Gore and others, or that government-centric policy fixes such as carbon trading won’t work. Those arguments should be aired and grappled with.
But frankly, there isn’t much serious scientific debate on the existence of anthropogenic climate change itself. Given the preponderance of scientific opinion on the topic, media outlets should be very skeptical of pieces that deny it. Almost always, they’re based more attitude than science. This doesn’t mean you can’t argue that climate models are flawed — they are — but if you run with that, make sure it’s a serious, rigorous argument.
What you shouldn’t do, though, is what Will did: cherry-pick headlines that appear to fit an unsupported thesis and pretend you are making a serious argument. This has the effect of discrediting your own position, that of the media you’re working in, and, indirectly, the science you cite.
All of this underlines how important it is to communicate the science clearly, to distinguish the specious arguments from legitimate ones – or else the whole debate breaks down. (And we’ll never figure out how to address this issue as a society.) I’m sure George Will doesn’t have editors question his opinions very often. But some things are not just a matter of opinion, and his editors have an obligation to get this stuff right. It’s journalism 101. Which is why the Post’s apparent decision to ignore its own failings here is so baffling.
Update: TPM’s Zachary Roth reports that Will’s next column comes out swinging against his detractors. Which will probably have the effect of ginning up more faux-controversy over the substance here, which is really not in dispute. That’s what a columnist gets paid for, I suppose, but something is seriously amiss here.
