David Keith vs the apocalypse

David Appell highlights this passage from David Keith's new book:
Imagine how effectively the world might collaborate if we discovered a massive asteroid inbound for a 2050 impact. But, this is not what we face. The claim that climate change threatens an imminent catastrophe is an attempt to play a trump car of (seemingly) objective science in order to avoid debate about the trade-offs at the heart of climate policy and about the role that values play in driving each of our personal judgements of the moral weight we accord to competing interests. But climate change is one of many problems, so there is no substitute for realistic assessment of our risks and open debate about the trade-offs between them, for we cannot avoid all risk or solve all problems.

-- David Keith, A Case for Climate Engineering
There's no question that there is a strain of apocalyptic thinking in environmentalism (is there any ideology that does not have some element of this?)  But as so often when you try to ascribe motives to people, Keith does not have this quite right.

Yes, some people picture climate change as an "imminent catastrophe." And depending on your definition of "catastrophe" or "imminent" you could be right by your own lights. But I don't think the appeal of the end-of-the-world thinking is that it short-circuits a debate about "values." The idea that we are having a conflict about values is just wrong, wrong, wrong. So what is the appeal?

In the first place you have to acknowledge the general appeal of extremism in political debates. This has been apparent for thousands of years, ever since there was a need to appeal to large groups of unrelated people using abstract ideas. Go back to the Greece of Thucydides, 2,500 years ago, and you find oligarchs swearing that democracy will lead to economic collapse, famine, incest, and cannibalism, and democrats swearing that oligarchs will crush the life out of the people, steal their money, rape their women, and so forth.

Extremism makes it easy to talk to low-information voters, which has always been a prime need of all political activists. Keith views environmental extremists as cunningly evading a serious and rational weighing of the relative risks and benefits of alternate courses of action. In reality, of course, insofar as shouting calamity from the rooftops is strategic at all, the strategy is to compete with other prophets shouting a different kind of doom from other rooftops.

An Assyrian clay tablet dating to around 2800 B.C. bears the inscription: “Our Earth is degenerate in these later days; there are signs that the world is speedily coming to an end; bribery and corruption are common; children no longer obey their parents; every man wants to write a book and the end of the world is evidently approaching.”[1]


Then, too, there is the even longer tradition of prophecies of doom, predicting an apocalypse that will consume the wicked. This goes right back to the Hebrew Bible and even before that. What appeals about these stories is not that they change the narrative of values -- prophets will have that conversation with you all day, every day, firmly in the belief that they are getting the best of the exchange. It is to reconcile their certainty that their values are correct and that they are in harmony with the universe with all the evidence around them that they have little power and the world is not ordered as it should be. This is the appeal of apocalypse stories to the devout, be they Christians, Muslims, extreme environmentalists, or libertarians (for libertarians, of course, the part of the Beast is played by fiat currency.)

The people who think the world is ending, imminently, should not be confused with the people who think the world is on a bad path, and needs to get on the right one, imminently. The two groups have plenty in common. They don't like large parts of the society we live in. They may dress funny. They may be strident and intolerant of gradualism. But while the former are in retreat from reality, the latter most decidedly are not. They are the Quaker abolitionists smuggling slaves to freedom, the women's suffragettes being dragged off to jail, the marchers on Selma and Washington braving the fire hoses and the dogs. And they are also, very proudly, the scientist arrested fighting mountaintop coal mining and the activist laying down in front of trucks to stop pipelines.

There is the judicious weighing of risks by armchair intellectuals, and there is action by those who have weighed the risks to those that cannot defend or protect themselves and chose to act, according to their own moral code. The latter may or may not succeed in affecting significant change; the former never will.

Dear Andrew Revkin: Time to rethink your dismissal of Cook et al

Doubling down:
The clear message of the team conducting this fresh assessment of the climate science consensus is that it’s vital to close that gap to have a chance of breaking societal deadlock on cutting greenhouse gas emissions. On his Skeptical Science blog, John Cook, the paper’s lead author, put it this way:
Quite possibly the most important thing to communicate about climate change is that there is a 97% consensus amongst the scientific experts and scientific research that humans are causing global warming. Let’s spread the word and close the consensus gap.
Forgotten [Really? Did they say climate communication was the only thing that mattered? No, they said "to have a chance." I.e., closing the gap is necessary but not sufficient condition, not the only thing that matters] in much of this is a point made in an e-mail message sent to me and some other science communicators this morning by Dan Kahan, the Yale law professor who studies the cultural filters that influence how people perceive and react to information. Kahan linked to his fresh post reviewing how many times in recent years such studies have been promoted, then asked this:
Climate scientists aren’t the only ones whose message never gets through. The “science of science communication consensus” that deficits in knowledge & rationality are not the problem [there's more than one problem!]— 99.9999999% agree! — never does either, & to the very people it should be of value too, viz., those trying to promote constructive engagement w/ climate science.
Is there someone studying that science communication problem???!
. . . 
This doesn’t mean it’s a waste of time to communicate climate science [in contrast to what you tweeted yesterday]. But it does mean that communicating the science of science communication matters, too.
For more on the wishful nature of hopes that closing such gaps will matter much, read Keith Kloor and David Appell.
Dear Andrew,

I like a lot of what you write, and I respect your ability to take a second look at your positions and well, it's time. Your own shifting justifications for why Cook et al doesn't matter should be a warning sign that something is amiss: "This study will not fundamentally alter the climate debate forever" (*) is quite a climb-down from "This is an irrelevant study that tells us nothing new and changes nothing."

The Cook study added a greater degree of rigor to the evidence that 97% of climate scientists agree global warming is happening and is human caused. Most Americans -- 70% in the 2011 Six Americas study -- do not know this. Attempting to defend the initial, rather rude and ill-thought-out, dismissal of the study reflects a natural and predictable defensiveness, but you should reconsider.

Neither the authors of the study nor anyone else claimed the study solved all the problems in communicating the science of global warming, still less that it showed a way past all the obstacles to collective political action.

But as a piece of science communication -- a subject you have written and lectured about on many occasions, and therefore seem to think is relevant in some way to the challenges we face -- it was a stunning success(**). Both your initial dismissal and the further attempts to justify it are wrongheaded and invite the label of "inactivist" which some have attached to you.


-----------------------------

* A point Appell makes in even more bizarre fashion when he crows ("Climate Candy: The Proof" (!)) that the Huffington Post is no longer leading with the study the next day (?)).

** Let us consider some of the reasons for its success:

1. A simple message.
2. Careful research that sticks to the facts.
3. A message grounded in what we know well, not in new science, extremes, or "single study syndrome."
4. Information that the disengaged (not aware it has been available for some time) have REPEATEDLY TOLD POLLSTERS would increase their concern about global warming.
5. Despite a message well-gauged to increased concern, it is not apocolyptic, not overwhelming, and not likely to make people want to "tune out" the issue.

The intolerant moderates






Skeptical Science won the internet last week with a superb original paper by Cook, Nuccitelli et al that evaluated over 12,000 sources and found 97% of climate scientists agree that global warming is happening.



Amazingly some people managed to miss the point:
Their names are practically a role call of the "intolerent moderates" -- journalists who have chosen to define themselves as independent-minded thinkers ready to castigate both sides. The intolerant moderates accept that climate change is happening and action is necessary, but struggle to occupy a middle ground condemning the excesses of both sides. Since the excesses in the climate debate are not at all equally distributed between science deniers and the concerned, this positioning often leads to tepid critiques of climate deniers coupled with energetic castigation of the other side for minor, or, as in this case, nonexistent sins.

Dave Appell just doesn't see the point of the study:
I'm not very keen on these kinds of numbers -- they are made for lazy journalists who don't want to examine the complexity of the science, reporters who just want a number that quickly and easily supports their position.
Or maybe reporters who want to convey to their readers a simple, rock-solid case that a majority of climate scientists believe climate change is real and is caused by humans something only 30% of Americans know to be true (Really).

Kloor is spouting the same sort of nonsense:
The latest example is this survey by John Cook et al that is getting a lot of undeserved attention in the mainstream media. I say that because, questionable methodology aside, the survey tells us nothing new and is, as science journalist David Appell noted, “a meaningless exercise.”
I enjoy their quoting one another for added support: but they are both completely, utterly, ludicrously wrong.

It's hard to say which is the more fundamental fail here: that Kloor doesn't understand that replicating results is critical to science, or that he thinks that he has somehow become a scientist, whose responsibility it is to follow and critique the bleeding edge of climate science, rather than his actual role as a science journalist helping the public grasp the critical core of the field, a job that evidently has to be done by scientists, who have pulled off a massive coup of science communication, only to be sneered at by the people who are paid to perform that function themselves.

I really expected better of Revkin than to jump on this bandwagon. This is why the survey is not a "meaningless exercise":

Source
Half of the public in this survey -- HALF -- said that if 90% of climate scientists agreed that global warming is happening, it would increase their concern. This mind-boggling result is possible, again, because SEVENTY PERCENT OF THE PUBLIC DIDN'T KNOW MOST CLIMATE SCIENTISTS THINK GLOBAL WARMING IS HAPPENING.

That three SCIENCE JOURNALISTS do not know this about their audience is scandalous. It borders on professional incompetence. These people are lecturing scientists about science communication?

UPDATE: In the comments, MikeH perceptively notes that the intolerant moderate is a subspecies of the VSP:

They are the Very Serious People (popularised by Paul Krugman in his NYT column)
(http://rationalwiki.org/wiki/Very_Serious_People)

"Valuing common sense over scientific consensus when there is a conflict. When pushed far enough VSP will eventually err on the side of science but will hold a candle for pseudoscience as long as it has a veneer of respectability.
Loves the hell out of the balance fallacy. They feel uncomfortable pointing out flaws concentrated in the right-wing or left-wing without pointing to an opposite example. "Both sides do it!"

Climate scientist 2+2=4
Denier 2+2=5
VSP 2+2=4.5
