More proof, if any were needed, that American conservatives are not conservative: they identify their opposition with the aristocracy via a (weak attempt at a) posh accent.
It’s a topsy turvy world down here. You never could tell the good guys from the bad guys from day one. Hey, Lord Monckton! These are not really your friends!
I don’t like this guy’s politics by the way, but I love his accent. That is the strand of Texas vernacular I aspire to.
And make no mistake, this ad shows he is running mostly on a platform of talkin Tixen and bein Tixen. And catch that Texas swing fiddle in the second half! Yeehaw! Yep, we may mess up the whole world before we’re done, but we shore do know how to have a good time! Now that’s conservative!
One big difference between the web and the old “news” media is that some stories stay current, and some bubble up later when you least expect it. I posted something on rec.food.cooking in 1994 or so about a salsa recipe heavy on the cilantro; normally I’d buy a bunch of cilantro and have no use for 80% of it until I learned how to make a red salsa adapted from an otherwise mundane little Mexican cookbook. This recipe is still floating around the net. I am sure I’ll come across it again…
People are making an error common to those comparing science to commercial software engineering.
Research: *insight* is the primary product.
Commercial software development: the *software* is the product.
Of course, sometimes a piece of research software becomes so useful that it gets turned into a commercial product, and then the rules change.
It is fairly likely that any “advanced version control system” people use has an early ancestor or at least inspiration in PWB/UNIX Source Code Control System (1974-), which was developed by Marc Rochkind (next office) and Alan Glasser (my office-mate) with a lot of kibitzing from me and a few others.
Likewise, much of modern software engineering’s practice of using high-level scripting languages for software process automation has a 1975 root in PWB/UNIX.
It was worth a lot of money in Bell labs to pay good computer scientists to build tools like this, because we had to:
– build mission-critical systems
– support multiple versions in the field at multiple sites
– regenerate specific configurations, sometimes with site-specific patches
– run huge sets of automated tests, often with elaborate test harnesses, database loads, etc.
This is more akin to doing missile-control or avionics software, although those are somewhat worse, given that “system crash” means “crash”. However, having the US telephone system “down”, in whole or in part, was not viewed with favor either.
We (in our case, a tools department of about 30 people within a software organization of about 1000) were supporting software product engineers, not researchers. The resulting *software* was the product, and errors could of course damage databases in ways that weren’t immediately obvious, but could cause $Ms worth of direct costs.
It is easier these days, because many useful tools are widely available, whereas we had to invent many of them as we went along.
By late 1970s, most Bell Labs software product developers used such tools.
But, Bell Labs researchers? Certainly no the physicists/ chemists, etc, an usually not computing research (home of Ritchie & Thompson). That’s because people knew the difference between R & D and had decent perspective on where money should be spent and where not.
The original UNIX research guys did a terrific job making their code available [but “use at your own risk”], but they’d never add the overhead of running a large software engineering development shop. If they got a bunch of extra budget, they would *not* have spent it on people to do a lot of configuration management, they would have hired a few more PhDs to do research, and they’d have been right.
The original UNIX guys had their own priorities, and would respond far less politely than Gavin does to outsiders crashing in telling them how to do things, and their track record was good enough to let them do that, just as GISS’s is. They did listen to moderate numbers of people who convinced them that we understood what they were doing, and could actually contribute to progress.
Had some Executive Director in another division proposed to them that he send a horde of new hires over to check through every line of code in UNIX and ask them questions … that ED would have faced some hard questions from the BTL President shortly thereafter for having lost his mind.
As I’ve said before, if people want GISS to do more, help get them more budget … but I suspect they’d make the same decisions our researchers did, and spend the money the same way, and they’d likely be right. Having rummaged a bit on GISS’s website, and looked at some code, I’d say they do pretty well for an R group.
Finally, for all of those who think random “auditing” is doing useful science, one really, really should read Chris Mooney’s “The Republican War on Science”, especially Chapter 8 ‘Wine, Jazz, and “Data Quality”‘, i.e., Jim Tozzi, the Data Quality Act, and “paralysis-by-analysis.”
When you don’t like what science says, this shows how you can slow scientists down by demanding utter perfection. Likewise, you *could* insist there never be another release of UNIX, Linux, MacOS, or Windows until *every* bug is fixed, and the code thoroughly reviewed by hordes of people with one programming course.
Note the distinction between normal scientific processes (with builtin skepticism), and the deliberate efforts to waste scientists’ time as much as possible if one fears the likely results. Cigarette companies were early leaders at this, but others learned to do it as well.
In general this relates to the common error of people putting expectations from their own professional lives onto other disciplines, including the endlessly misplaced emphasis on frequentist reasoning in climate from engineers and MDs (Crichton and McIntyre both), or the desire for tight proofs from physicists (Dyson, Laughton, even Motl). In neither group is a “balance of evidence” argument useful, but that’s how most of earth science works.
Judith Curry leaves only one possible argument for doubt that she has jumped the shark.
You’ll need some context for this one:
Lets frame belief, disbelief, and doubt in the context of the Italian flag, that was introduced previously on the hurricane thread in which evidence for a hypothesis is represented as green, evidence against is represented as red, and the white area reflecting uncommitted belief that can be associated with uncertainty in evidence or unknowns.
Let’s look at an example in the above-linked article:
Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.
This statement is often used as a litmus test for belief regarding global warming, i.e. you believe this statement (consensus) or you don’t (skeptic). Very likely denotes a probability of anthropogenic influence between 90 and 99% (lets pick 95%) and I interpret most to mean between 51 and 90% (lets pick 70%), with the remainder (30%) associated with natural variability. Hence, the Italian flag analysis could represent this in the following way:
5% assigned to uncommitted belief (white),
67% assigned to anthropogenic forcing (green),
28% assigned to natural variability (red).
my personal weights for the Italian flag are:
My assignment allows the anthropogenic influence to be as large as 70% and as small as 30%
As I have pointed out previously, that last sentence is immensely sloppy, conflating a hypothesis (a proposition that must be either true or false) with a weighting.
Now, I believe (and haven’t really made the case) that weightings are much more useful in decision making under uncertainty than are hypotheses. But that’s not the issue here. The issue is that Judith Curry, in unveiling her new intellectual tool with great fanfare and off-key notes of false modesty, conflates confidence in a hypothesis with weighting.
- p (f < 50%) : 0.02
- p (f > 50%) : 0.98
- p (f < 50%) : 0.02
- p (50 % <= f < 60%) : 0.02
- p (60 % <= f < 70%) : 0.1
- p (70 % <= f < 80%) : 0.72
- p (80 % <= f < 90%) : 0.1
- p (90 % <= f <= 100%) : 0.02
Historical surface temperature observations over the 20th century show a clear signal of increasing surface temperatures. Italian flag: Green 70%, White 30%, Red 0%. (Note: nobody is claiming that the temperatures have NOT increased.)
OK, is it fair to say that “Note: nobody is claiming that the temperatures have NOT increased” means that nobody claims that “Historical surface temperature observations over the 20th century show a clear signal of increasing surface temperatures”? I mean, if nobody can claim the contrary, then the signal must be clear, right? So what does that white 30% represent? Does it represent 70% “it has warmed and I can deal with it” and 30% “it has warmed and I am in denial”? Or does it represent “although nobody claims it hasn’t warmed, and there is a 0% chance that it hasn’t warmed, there is still a 30% chance that it hasn’t NOT warmed?”
Now consider the adulation that this muddle obtains from the peanut gallery. (Note, there’s plenty more where this came from, but this is from another essay in the series. Thanks to bluegrue in comments.)
Oliver Manuel: Thank you, Dr. Curry, for having the courage to question the way uncertainty has been characterized in climate assessment reports.
Gordon Ford: Excellent post. When we were young we all feared “the monster under the bed”. Many have not learned to live with monster. In the real world (such as gold mining) one learns to live with the error in the estimate exceeding the estimate.
Paskvacs, eggcorning fiercely: I’m personally in favor of letting science guys work this out all by themselves. If they end up committing suicide, so be it. Say “La V”. But, as soon as you try to ‘reasonably’ let the legal system (with any new tweaks you want add) get their greedy little hands on anything like this fiasco, you –and not the scientists– are the one committing suicide.
hunter: Very interesting. I like this concept very much.
MaxL: Thank you, Dr. Curry, for introducing the discussion of uncertainty and questioning the way it has been used in climate science.
Baa Humbug: Would it be fair to say, if the true uncertainties in the climate models were enunciated clearly, Kyoto would not have happened and Copenhagen would have been a side show attended by a handfull of people?
and finally I will quote the entire comment of one Danley Wolfe along with Curry’s response
Danley Wolfe: Judith,
this is a great post. I think the phrase “(t)here can also be epistemic uncertainty about how a physical, chemical or biological process works is extremely important. Scientists suffer from “completeness fallacy” meaning they need to carry through work to some meaningful level of completion (for reasons such as need to mark progress, need to publish, need for peer recognition, need to meet deadlines for IPCC assessments, etc.). A model which lack sufficient treatment of all suspected independent variables – and their interaction is – under- ie., mis-specified. Result is that the model will tend to over-emphasize or under-emphasize attribution for the variables that are fully treated. I have long suspected this to be the case in climate modeling for global warming. There are many forcings and some are known to be underrepresented in the modeling such as aerosols / clouds and black soot.
curryja: Danley, very true, same goes for solar also.
OK. I am stretched to the limit. Somebody has to call “horseshit” here, and it might as well be me.
Admittedly, she is very highly published. I know a couple of her students and think highly of them. On the other hand, to be honest no paper of hers has ever come across my radar in anything I’ve investigated. (As a dilettante, I don’t contribute much to the primary literature myself, but I do read a whole lot of stuff.) I mean, could this be the stuff of some subtle neurological decay, where a formerly competent scientist starts making no more sense than the peanut gallery? After all, dedicated naysayers are still highly intelligent and scientifically competent by comparison to the lay public (that’s the whole problem) even though they are actually quite ignorant and confused about the actual science. So a decline to that level of functionality would not be obvious, and if a person already had tenure, it would ordinarily go uncommented upon.
Or alternatively, is the peer review system so shabby that a person of modest intellectual accomplishments, one who, despite years of connection to the scientific community, numerous publications and promotion to a position of responsibility, is capable of such vapid, illogical, pointlessly contentious writing.
Either way it’s sadly amusing to see this nonsense treated by the fan base as the breakthrough in reasoning about uncertainty that it obviously isn’t.
But as far as I can see, the uncertain hypothesis raised here is
Well this is entertaining. MT and others seem annoyed because they think I invented uncertainty or am taking claim for it or something? Hardly. Its the Emperor’s New Clothes thing. And the fact that MT and others don’t get it (i.e. that uncertainty and allegations of overconfidence of IPCC are important things to talk about, its the naked emperor, really) just tells me how clueless some members of the community actually are.
I give MT credit for at least discussing what i say in the blog, rather than rehashing old drive by comments that I’ve made at other blogs. But i suggest he try out his arguments over at my blog, where they would receive some real dissection from some serious experts in logic, bayesian reasoning, etc. Nobody ever burns their bridges with me in terms of meaning i wouldn’t pay attention to their argument.
I have to admit this is a surprisingly gracious response to my less-than-gracious posting. I am, in that regard at least, impressed and grateful.
I still can extract no sense from the Italian Flag arguments to date; it seems to me that there is no unifying method at all, just a sort of fig leaf for various commingled classes of rough intuitive guess.
Now, arguably that is all that IPCC is providing, and all we’re discussing is whose intuition is more reliable. If that is the case, though, that is how it should be discussed. Devices intended to illuminate should not obfuscate.
If you want to discuss uncertainty, and decision-making under uncertainty, by all means, let’s do that. (I’ve been trying to close that loop for decades, myself.)
As for the critique of models which so exercises Tom Fuller, let me withdraw it for the sake of more productive argument. If Dr. Curry wants to throw red meat to the inactivists on occasion, she should be held to account. But that only a secondary cause of my disappointment with her contributions to date.
Let’s focus on where the focus belongs, on how to think about uncertainty.
If Dr. Curry will continue to allow me to post on her site I will actually be grateful but I will nevertheless behave as an ingrate. If Dr. Curry is to make a genuinely positive contribution to the problem of how to deal with uncertainty in the high-stakes field of climate policy, she will need to proceed at least with considerably greater clarity than she has managed to date. It’s my impression that considerably greater care is needed as well.
I will continue to be an advocate for clarity and precision of thought. I hope others with some interest in uncertainty will stop yielding Dr. Curry a free pass on these matters, where she is an obvious novice.
If she actually wants to participate in a discussion of uncertainty, then it is important to do so carefully. One aspect of the problem is separating out one’s own biases from the various other sources of error, and another is careful thought along lines that are unfamiliar to most physical scientists. The casually appealing ideal of “separating politics from science” may turn out to be more subtle of a matter than it might at first appear.
I guess I was in a dreadful mood, too. The world is looking particularly messed up to me these days. (Willard has taken to calling me Doctor Doom, but I assured him that I am Victor to him.)
I really do think Judith Curry either jumped the shark or was never on this side of the shark. This flag stuff really looks very amateurish.
It might have been more prudent on my part not to ask the question in that way. But I did want the whole issue to get some attention, and in that I succeeded. I certainly wont apologize for this flavor of criticism to anyone who doesn’t hold McIntyre to a comparable standard.
I’m impressed by the constructive spirit in which she receives this criticism. I will be more impressed if she actually addresses it. Indeed, sharks of this breed can be unjumped, as it appears Claude Allegre has just demonstrated. I’m willing to grovel on the substance if somebody can make a coherent case for it.
Update: Pleased to see James in agreement.
Update: Fuller raises the interesting question as to whether I posted this out of scientific or political motivation (or, for that matter, out of sheer self-destructive stupidity, which I’ve been wondering from the start).
Here’s my defense.
While there is no room for ad hominem arguments in science, what Curry is doing is apparently very far from science. Then the question of what she is doing and why becomes relevant as a political question, yes. I present a case that IFA as we have seen to date is not science.
Is she doing not-science because a) she knows it is not science and wants to fool others b) she is no longer capable of doing science or c) she was never capable of doing science?
Now, I can assure you on the basis of experience that this conversation is going on behind the scenes among actual, real scientists. The question is only whether I was right or wrong to raise it publicly, to bring it into the open.
There is no doubt I was rude within the norms of science. I stipulate that.
The credulity and adulation associated with the transparent nonsense has been a matter of some political importance. There has never been much risk that this nonsense would percolate up through scientific discussions, but there is an increasing risk that it will be forced down to science from the congressional level. So arguably it’s important to raise the question, and I did so.
In this case, the contradictions are elementary enough to be accessible to a diligent political staffer. So making the case in such a way that such a staffer would be likely to come across it and work through it may be important. It’s not hard to imagine this cluster of half-baked ideas making its way into the national discussion via too much credulity at the top.
Therefore, for a change Tom Fuller is right. My motivation is indeed political. I wish to defend science from an injection of nonsense from the political level. Lysenkoism never works out very well. And Lysenkoism is exactly the central risk of politicization of science.
I wrote this in June of 1992. It’s nowhere near as clever as I remembered it, alas. I had been a student of climate science for about 2 years at this point. As youll see it’s not without some merit, but it reminds me now of the confused nonsense on the Watts site. (Sheepish grin…) This should encourage us that people are corrigible, but that it takes a long time.
Of course, back in the old days internet musings about climate had an audience of about twenty-three souls. So it didn’t matter that much. Those were the days…
Here’s my prognosis for the broad historical outline of the next few
decades, as they will be remembered by the far future. I do believe
that global change issues will be the dominant feature of the coming
period. I am also confident that deliberate human intervention on a global
scale will eventually occur, and probably fairly soon.
==== BEGIN SCIENCE FICTION
“The end of immediate prospects for massive nuclear exchanges around 1990
combined with increasing awareness of the huge impact humanity was having
on the global environment. The first international conference on the
environmnet, held in Rio de Janiero in 1992 was a turning point.
The USA, representing the world’s largest market and economy, felt immune
from external economic pressures, and found itself alone in maintaining
an economy-centered view at the conference. This, while politically useful
internally in a weak economy and a three-sided election, and also much
(though quietly) appreciated by certain economic interests in Europe, profoundly
weakened the global geopolitical position of the United States, driving the
developing nations into a much closer connection with Western Europe, as
global attention shifted from nuclear to environmental security.
Shortly thereafter, many of the rainforest nations, and notably and
quite vigorously the Brazilians and Indonesians, made major efforts
to stop the extensive burning of the rainforests. This period also coincided
with the major volcanic eruption in the Philippines, Mt. Pinatubo, in 1991,
and also with a period in which the greenhouse warming was just beginning
to accelerate to alarming proportions. This acceleration had been largely
masked by the volcanic eruption, and had also been considerably slowed
by the smoke from the enormously extensive burning of the rain forests.
The sudden lifting of these two masking phenomena around 1994, combined
with the rapid background increases in radiative forcing, led to the
Great Warming of the 90s. Agricultural failures were widespread, and
sea surface rises which had once seemed hypothetical now appeared imminent.
Extreme heat waves occurred in parts of America and China, causing much
human suffering. Demands for action were heard worldwide.
Suggestions for massive tree planting were widely implemented, but the
impact of these measures was slight. Then some wags suggested reinstating
the burning of the rainforest, and the possibility of massive deliberate
dust releases entered the public awareness. Environmental purists were
outraged, feeling that anthropogenic mitigation efforts were somehow as
immoral as negative anthropogenic impacts. This position was inadvertently
bolstered by some technophiles who claimed that economic activity should
be untrammelled by environmental concerns, and that repairs to the damage
could be implemented more efficiently and cost effectively than by limiting
the activities in the first place. (Of course, time has proven both these
positions to be drastically incorrect.)
In fact, the economic so-called conservatives ended up being a larger
impediment to the implementation of the Massive Dust Release Programme
than the so-called greens, the latter group being neutralized by the
support for dust releases by the majority of professional biologists and
ecologists who felt that the pace of warming represented an immediate and
profound threat to already highly stressed ecosystems worldwide. The
so-called conservatives resisted the loss of national sovereignty to
a worldwide institution that would be required to coordinate and regulate
the emissions due to economic activity, and to allocate the required
emissions to the appropriate geographic locations.
Nevertheless, in 2005, with the enthusiastic participation of the North
American Bloc, the World Organization of the Ocean and Atmosphere
(WOOA) was formed, the first actually sovereign instrument of world
government, with the participation of almost all countries. By 2019, the
few minor holdouts had been pressured into participating, with Kazakhstan
and Libya being the last to join.
In subsequent decades, control over climate was improved with careful
allocation of CO2 and dust emissions and sensitive salinity controls over
ocean currents. Massive ecosystem loss continued for some time, but the
climate control itself went well for about two centuries, until the source of
carbon was depleted, and suddenly the world faced the prospect of Global
Cooling, but that is a subject for a later chapter…
==== END SCIENCE FICTION
Here’s my review from Future Me:
Main points right: recalcitrance of the US, relatively rapid emergence of climate into public and political awareness. Right on right and left wing resistance to geoengineering. Looking on target about a gradual slip into geoengineering.
Stupidly wrong, that climate control is the first step of global governance. We already had the GATT when I wrote this.
Woefully wrong that the less developed countries could or would make climate a priority. Absurdly and sadly wrong that once push came to shove anybody would gave a rat’s ass about preserving ecosystems. I don’t know when ecological conservation became a lost cause. It feels like a long time.
A first pass at a greatest hits list; updates will not necessarily be noted as such. I had a request for key papers in the history of modeling so the emphasis leans that way. Also a few books listed.

Choice quotes from today’s NYTimes:
- “It’s a flat-out lie,” Mr. Dennison said in an interview after the debate, adding that he had based his view on the preaching of Rush Limbaugh and the teaching of Scripture. “I read my Bible,” Mr. Dennison said. “He made this earth for us to utilize.”
- “This so-called climate science is just ridiculous,” said Kelly Khuri, founder of the Clark County Tea Party Patriots. “I think it’s all cyclical. Carbon regulation, cap and trade, it’s all just a money-control avenue,” Ms. Khuri added. “Some people say I’m extreme, but they said the John Birch Society was extreme, too.”
- “They’re trying to use global warming against the people,” Ms. Deaton said. “It takes way our liberty. Being a strong Christian,” she added, “I cannot help but believe the Lord placed a lot of minerals in our country and it’s not there to destroy us.”
