Stop looking for specks of climate skepticism

Since it’s Sunday, I feel called to preach. My text:

Why worry about a speck in your friend’s eye when you have a log in your own? (New Living Translation)

Here are some specks and logs that showed up in this week’s #scicomm stream of thought.

Responsibility for polar bear arguments

Harvey et al., “Internet Blogs, Polar Bears, and Climate-Change Denial by Proxy” (2017) identifies an argumentative strategy used by those who question the links between climate change, arctic sea ice, and declining polar bear populations (TWQ):

the main strategy of denier blogs is therefore to focus on topics that are showy and in which it is therefore easy to generate public interest. These topics are used as “proxies” for AGW in general; in other words, they represent keystone dominoes that are strategically placed in front of many hundreds of others, each representing a separate line of evidence for AGW. By appearing to knock over the keystone domino, audiences targeted by the communication may assume all other dominoes are toppled in a form of “dismissal by association.”

Stripping this of its mixed metaphors, the claim is:  TWQ claim that by refuting the arguments about polar bears put forward by those on the side of the authors (or angels, TOTSOTA), they are refuting the existence and significance of AGW.

I think this is an accurate statement of one TWQ argumentative strategy which (unlike Harvey et al.) I will document below. However, Harvey et al. are mistaken in taking this strategy to be illegitimate. Quite the contrary: the TWQ strategy is a well-justified and strategic response to the case made by TOTSOTA. To throw in another metaphor:  TWQ polar bear arguments are TOTSOTA chickens coming home to roost.

New York Times: Your reporting fed McCarthyite attacks on Kevin Folta

So, follow below the fold to find my defense of these three claims:

1. Folta is an outstanding science communicator.
2. He is being targeted by McCarthy-style attacks.
3. The New York Times and the Chronicle of Higher Education failed to resist the McCarthyism.

The cost of hidden metaphors

The New York Times’ blog Scientists at Work is a good example of how scientists’ communication might focus on process, not results.  I’ve been enjoying the current sequence about glaciers in Bhutan;  each episode ends with a cliffhanger!

A couple of words in the most recent post jumped out at me, though.  In addition to “reconstructing the history” and “behavior” of the glacier–how it “changed in the past”–the scientist-author explained his interest in figuring out what the glacier was like when it “last maintained a robust, healthy profile.”  Healthy?

“Burden of Proof” #1: Managing our own thinking

In the discussion over at Climate Etc. a couple of weeks ago, there was a particularly clear instance of a move I see a lot–in the blogosphere, and in regular arguments:

I think most people who like science and are interested in climate science would welcome more “skeptic” arguments that meet the above criteria. It is a relief, even when disagreeing, to have some sort of a common language and set of expectations. Without that, argument is pointless, or to put it another way: The first thing you need to prove to me is that your ignorance is something that concerns me.

That’s exactly what I decline to do. The hockey stick needs no defense. Rather, you need to find some cogent explanation of why your ignorance of paleoclimate concerns me.

The writer here asserts that his position “needs no defense”;  it’s up to his opponents to produce reasons–or in other words, they have the burden of proof.

Of course, both sides can make this move.  Another writer comes back later in the discussion to assert that it’s the “hockey stick” [graph] that needs the defense:

There is no basis for discussion about AGW that starts with “the Hockey Stick is correct and unassailable”.

The true statment is  “the Hockey Stick is part of a very large con game and until the AGW side acknowledges that and apologizes, nothing they say should be believed.”   [Later:]   AGW is discredited until it confesses its fraud.

And this argumentative move–“MY position stands until YOU meet your burden of proof”–isn’t just confined to the climate debate.  Should genetically modified crops be presumed to be safe, until there is definitive evidence that they are harmful?  Or by the precautionary principle should this kind of new technology be considered dangerous, until it is shown to be safe?

To straighten out what’s happening in these moves, I want to distinguish between (a) the way people are using “burden of proof” to manage their own, personal thinking, and (b) the way they are using it to manage the debate they are having with other people.  For more on (a), proceed below;  (b) will follow in the next post.

Making arguments expensive

Back in the golden age of the climate controversy–say, about 18 months ago–there was a time when everybody was challenging everybody else to debate. I suppose you couldn’t click more than a few links before tripping over a gauntlet.

What does a formal debate offer that the ordinary disorderly flow of arguing in the blogosphere doesn’t?  To pick up on a theme from my last post:  a formal debate allows the participants to control  what they are taking responsibility for–and to force others to take responsibility, too.  Roger Pielke, Jr. is a masterful debater, and his recent challenge to critics of “climate pragmatism” shows this strategy at its finest.

Debate in the blogosphere: A small case study

Steve Patterson over at RAIL recently wrote a typically fine piece on How Comments are Killing the Commons.   Coming at the subject as a student of public discourse, I find myself a little more tolerant of the blogosphere’s “partisan clowning” etc.  I’m more curious about specific communication strategies we can adopt to make comment threads work.  Steve McIntrye of Climate Audit recently referenced an essay by myself & Michael Dahlstrom, and my participation in the comment threads gave me an opportunity to observe close up several helpful and unhelpful strategies at work.  Here are three things I learned about blogospheric debate, especially in contrast to communication in more face-to-face settings.
