Hi, I’m a theoretical physicist and have followed climate research for something like 20 years. I have actually often been wondering about exactly the topic of this post: the employment of advanced statistical analysis within climate research. From the friends and acquaintances that I have within climate research I never got the impression that the full force of statistical analysis was being used – something which seems to be confirmed by your post. I think it is very important to do so – to perform credible test of hypotheses and to extract information from large sets of data modern statistics seems indispensable.
Thanks for another enlightening post. I found it interesting how much of the issue revolves around language and definitions. When you mention “standard conventions” in the last paragraph, is that what you are talking about: making sure everyone is using the same meaning for the same word (such as ‘uncertainty’) in a given context?
[Response: Yes, that's part of it, but not the whole story.
There are some conventions already regarding results from model results, naming of variables, and meta-data/attributes (netCDF 'CF' conventions used in the WCRP community). The range of data is wider than just model results (e.g. station records, climate proxies and indexes, and various types of analytical results such as empirical orthofonal functions and gridded data), and there is a wider range of formats used among these (try different portals for getting station records and you get ASCII files with differnt looks).
The attributes which already exist are well-defined, but there seems to be a need for a more extensive glossary and more attributes (e.g. on evaluation of the methods in addition to new aspects coming in with more elaborate earth system models). Hence, the idea is to link the attributes and a commonly respected glossary, both for exchanging data between methods or scientists, and between climate services and non-scientists. A common convention could lead to more fruitful collaboration - I call it the 'lego-principle' where it's easier to build on others work. -rasmus]
As a student of climate science with some Physics training, member of AGU and AMETSOC, and as professional statistician, my view of what I have seen is less like the situation in the medical community where sometimes statistics is brought in as an afterthought (but see http://biostat.mc.vanderbilt.edu/wiki/pub/Main/FHHandouts/bayes.short.course.pdf), and more that climate science is being asked to do more and more with less and less, including being coupled to economic and policy models. As it stands, Geophysics (catchall for Climate Science and Oceanography and Atmospheric Sciences and …) is a descriptive and explanatory discipline. It has, in many areas, properly adapted to the Bayesian revolution. But to the degree to which The Public asking what, from a purely scientific viewpoint, might be Unreasonable Questions regarding time frames and attributions of specific phenomena, the standard Bag of Tricks seems strained.
Here, then, is the place, need, and role for a fervent community of statistically minded explorers, ones who can, because of experience with Economics and even Political Science, bridge the gap between phenomena and characterizations of risk, and do it in ways that can inform policy and The Public. This is why in climate work, as in my own professional practice, I find Bayesian approaches so valuable: They allow answers and estimates and decisions from nearly any motley assortment of information, and declare how good their assessments are.
There’s also a need, I think, to work these at multiple time scales. We, collectively, want to know what the next decade or two will bring. But, in the end (or in the limit), greenhouse gas emissions need to get to as close to zero as they can be, irrespective of what’s finally decided about geoengineering, and asymptotic impacts on civilization are likely to be substantial, even if we do get our collective act together. The long view is one of the purposes of The Azimuth Project (see http://www.azimuthproject.org/azimuth/show/HomePage) spearheaded by Professor John Carlos Baez.
Meanwhile, there’s lots that can be done with checking assumptions of analyses, and bringing the best known to bear upon climate questions, in the small and in the large. My sense is that statisticians working in time series and Bayesian methods just love to crank on new kinds of problems, in part to show off new algorithms, in part to strain and test them with genuinely hard tests, and in part to serve.
Is there some kind of a summary article or book I could read on statistical methods in climate science? Statistical inference is a subject close to my heart, and I am particularly interested in the methods used to reconstruct historical temperatures from various proxies, as well as CO2 content. I imagine these are well-understood problems, so I am hoping for a reference that is readable by a physicist with a background in statistics but very little in climatology.
[Response: Von Storch and Zwiers, Statistical Analysis in Climate Research is an excellent reference. CO2 content does take much statistics (other than the statistics of instrumentation -- reproducibility of measurements --something that is pretty simple and really well understood) since it is a globally well mixed gas. Temperature is harder since getting from proxies to temperature is not straightforward, and then averaging properly over the globe requires some form of interpolation. Lots and lots of literature on this. --eric ]
This ties in nicely with the recent paper by Cowtan and Way. Geostatistics is an advanced discipline at this point and I was really quite surprised that something like their work wasn’t already part of the routine workflow.
It is refreshing to see source climate statistics instead of seeing its vocabulary misapplied to support self-delusion of climate change causation – as: “Did global warming cause this weather event?”
It may be worth further simplifying your perfect weather/climate definition, now to say that a series of weather events makes up a climate, and climate is defined as a group of weather events. Your definition is more concise and correct, but in plain speaking, I want to say that EVERY weather event – even the most anomalous, works to define a climate, and any newly defined climate will include the weather events that define that climate.
In the past I have been shocked to hear meteorologists publicly address the issue and apply the 30 year rule to define a changed climate. By confusing causation and correlation- it works to misdirect a lay audience. I, along with the press need a fundamental understanding of climate statistics, Thanks for the links and lesson plan.
Perhaps we can now answer this way: “No. global warming did not cause this storm, but it certainly correlates with our warming, destabilizing climate.”
Standards in data formats is a great idea. To see this in a wider context, I wish biologists could get their heads around this (I do bioinformatics). Take just one kind of data: short segments of DNA sequence. These are usually published as genomic coordinates (chromosome, start and end positions), rather than the actual sequences, since this is generally more compact. Now you start running into problems:
– there can be more than one instance of the same genome with slight variations even though they are ostensibly the same version
– some use 0-based coordinates, others 1-based coordinates, and the format doesn’t always make it clear which is intended
– coordinates are often reported in tables in formats not designed for easy extraction by scripts like MS Word, Excel or worst of all, PDF
A big part of the problem is that the reward system targets publishing, rather than data management. Even journals that actively encourage supplying data don’t police the reusability of the data too closely.
On the whole reusability of climate data is not that bad compared with some other sciences. At least a fair amount is published in clearly documented formats.
I enjoy this site even as only a science dilettante. I need help (ideally from a real climate scientist). A long time online chess buddy is claiming to be a scientist and is showing signs of denialism saying the media is exaggerating and in turn influencing science. Could you please visit the following link and please at least make a short response to his posts – his username is turbojuice (I am billyraybar). Thank you. http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?dln=526141;pid=491840
Some media do, in fact, exaggerate warming claims. The point is to focus on the science and the peer-reviewed literature not the politics and the blogs. Of course he won’t want to hear that unless he’s a scientist.
For some additional context, see Climate and Statistics Workshop @ NCAR, 2007, which had both good climate scientists who did statistics and statisticians generally involved with climate and/ore geospatial work, on this agenda.
Most talks are good (one isn’t), but I especially recommend (statistician) Jim Bergman’s presentation, including thoughful comments p.19:
‘How can statisticians become involved?
The Key: Becoming involved in a ‘team environment’ with scientists.
• NCAR, where teams operate
• SAMSI (and NPCDS), where teams can be formed
• National labs (both LANL and LLNL have climate/stat teams)
• Large interdisciplinary grants available today
• Statistics cannot generally fund involvement of statisticians in other
disciplines which, in turn, rarely have much money for statistics.
• Shortage of statisticians
• The time needed for a statistician to get deeply involved with
another science and to also learn the statistics needed for it.
• Scientists often have a hard time judging what they can do
themselves and when they should seek statistical help.’
Bill #12: what the media exaggerate is the contrarian case. It’s tobacco and AIDS denial all over again – a faux debate. There are many uncertainties in the science and the occasional finding that pokes holes in details, but claims that warming stopped in year X, there is an ice age imminent, etc. are given undue prominence when there is no real evidence for this sort of position, just as there is no real evidence that tobacco isn’t a health hazard, or HIV doesn’t cause AIDS.
Science is never 100% certain – anyone taking a contrarian position who is 100% certain is not taking a scientific position, but the media mistake this sort of bravado for a real position on the science.
Nice article thanks. Yes there’s complexity of experts managing mathematical models and statics. The major over-riding issue that causes ‘extreme events’ in understanding across the board about climate science is “semantics” – not enough attention is spent on this.
what can make sense to scientists and mathematicians still will not make sense to 99% of the worlds population.
and thus the Blogosphere and think tanks of raving nutters on climate science.
The responsibility of being clearly understood is totally upon the shoulders of those wishing to communicate something from themselves to others. Until that is improved doesn’t make much difference how good or accurate the science is.
imho, the worst thing that has negatively affected global understanding of the importance of climate science and future risks was in fact Al Gore’s Inconvenient Truth. Good intentions can sometimes be a road to hell. cheers fwiw. sean
Sean: “The responsibility of being clearly understood is totally upon the shoulders of those wishing to communicate something from themselves to others.”
Horse crap! Communication is a two-way street, and half the fricking country has barricades of burning tires set out just to forestall any efforts at scientists trying to make inroads. There is no shortage of talented communicators telling anyone who will listen how deep we’re in the mud. They can express it at any technical level with any degree of politeness, and they will be met with morons who insist that their ignorance is superior to the expertise of the expert.
Here’s a newsflash, Sean. Al Gore got most of the science right! He and his message were attacked solely because he was Al Gore. What is more, Al Gore was saying the same things for over a decade before AIT. At any time, one of his many conservative colleagues from the Senate–who know as well as Gore does that the threat of climate change is real–could have stood up with him. Voila! The politics would have been neutralized. But where was John McCain? Where was Colin Powell? Hell, even Dubya had to ultimately admit climate change was real.
Climate change is only a political issue because half of the political spectrum in the US, the UK and Oz lack the courage to admit it is real.
@19 Hi Ray. ‘relax’?
re “Horse crap! Communication is a two-way street,..” No it is not mate. Dialogue and discussion is a two way street. Moving knowledge from point A to point B in a manner that it will “effectively” be understood by B is a ONE WAY street.
That is the issue I was speaking to. And it is not ‘horse crap’, it’s valid true and correct. In my personal experience (including mngt and staff training 1on1 and in a classroom) and my firm opinion. I also believe there is manifold evidence of this in academic circles in particular linguistics, advertising, and human psychology fields. You may disagree, that’s fine.
My comment about Al Gore (who I admire for doing what he did btw) had nothing to so with what % of the science he got right. This is a comments section so i try to keep it short. have another look what I said “the worst thing that has negatively affected global understanding”. In retrospect I believe there was a better way, as it caused more problems in understanding over time than it solved.
The IPCC or some other formal body would have been better placed to “produce” such a work as Gore did and simultaneously taken full responsibility for what was presented .. and then followed through with such a marketing / information / education campaign to politicians, public leaders, business, and the public.
These “one offs” uncoordinated attempts by individuals incl real climate have very limited positive impact in public opinion overall. Why? Because they are easily undermined by a more coordinated “marketing campaign” that is highly funded by very serious self-interest groups and self-opinionated elites with an over inflated view of their own abilities, insights, and wisdom.
also fwiw re: “Climate change is only a political issue” … because it was always a “political” and “public policy” issue and not a science issue. On this score ex-PM John Howard is correct. But that’s the only bit he got right in his recent speech. Best to you.
@19 ps And I stick to this …. “The responsibility of being clearly understood is totally upon the shoulders of those wishing to communicate something from themselves to others.”
It doesn’t mean that some people on the receiving end might well be intellectually incapable of comprehending nor may refuse to listen. But that is a different story. The responsibility first rests with the speaker not upon the receiver. If one cannot gain and hold the attention of the public, it is NOT the public’s fault. Is this not true? If not why not?
These comments go back to the statistics issue of the article. Even between intelligent acadmeics issues arise over “semantics” and meanings of statistical terms and methodoliges. If they have difficulty, then poor old Joe Public with the matter of “semantics”. Poor use of words leads to confusion.
In the IPCC glossary AR4 & AR5 they speak of forecasts, projections, predictions and predictablilty. The nuances may be clear to a climate scieitists or IPCC report author, but the only thing the public get is the glossary. menawhile the IPCC Reports do not in all cases follow the word meansing in the glossary anyway – plus sceptics never follow the meaning s and make it up as they go. With no care no resposnibility whe they misrepresent the IPCC Authors.
How dare they do that and get away with it? I say this – the IPCC allows it in the first place and left the field of play leaving it to Al Gore, and any other motivated individual to do the “communication” job they have not done. Thus it is all screwed up over crap like “hiatus / pause / not hitting “the IPCC predictions” etc. What ‘predictions’ I ask? The IPCC don’t do ‘predictions’ anyway. Not in the SEMANTIC sense that word has in the real world of Joe Public. THUS the naysayers win, because it was so easy to win.
Unless Ray or anyone else can prove to me that a 6 month old baby or a 3 year old child is 50% or equally responsible for the communication process of a parent educating them about life’s basics and who is in charge… & responsible for ‘communication’ …… ? Cheers
Communicating something as complex as AGW, essentially involving the whole field of climatology, in a complex, global, political environment is never going to be tidy as say, a chess game. Though I’ll admit there has occasionally been some resistance when it comes to prying tetchy climate nerds out of their ivory towers.
Amy: If this humiliating experience is really troubling you, there are things we could do about it.
Sheldon: For instance?
Amy: Well, the first thing that comes to mind is isolating the part of your brain where the memory is stored and destroying it with a laser.
Sheldon: Hmm, no. One slip of the hand, and suddenly I’m sitting in the Engineering Department, building doodads with Wolowitz.
Amy: All right. Have you considered improving your socialization skills, thus allowing you to communicate more effectively with other people?
Sheldon: Isn’t that their burden? I’m the one with something interesting to say.
Amy: Fair enough, but in its essence, teaching is a performance art. In the classroom paradigm, the teacher has the responsibility to communicate, as well as entertain and engage.
Sheldon: I sense that you’re trying to slow-walk me to an epiphany. Would you mind very much jumping to it?
Amy: Perhaps you should consider taking acting lessons.
Sheldon: Acting lessons. Interesting. It might help if I could act as though I care about my students and whether or not they learn.
Sean: “The responsibility first rests with the speaker not upon the receiver.”
I’m gonna go out on a limb here and guess that you haven’t interacted with teenagers much. Dude, if an audience is not willing to entertain the message, it doesn’t matter how the speaker presents that message.
Sean: “The IPCC or some other formal body would have been better placed to “produce” such a work as Gore did and simultaneously taken full responsibility for what was presented.”
Because nobody has ever challenged anything the IPCC has said. Unh-unh. No way. Never. Dude, did you just wake up after a 30 year nap? The IPCC is one of the most villified organizations on the planet. There are nutjobs that think they have their own black helicopters and death squads! And some of them are in the US Senate!
OK, Sean, convince me. Give me 10 concrete things scientists should be doing that they aren’t already doing–keeping in mind that they are first and foremost scientists who already have the overwhelming responsibility of increasing human understanding of the planet’s climate. Don’t give me BS suggestions like “Scientists need to speak up!” They are already doing it–and getting death threats when they do. Don’t tell us they need to engage the public and explain the science–they are already doing that and being shouted down when they do. Don’t tell me that they need to advise policy makers. They are already doing so for those who will listen. And for their trouble, they are branded “activists” and accused of perverting science.
Sean, you may get the feeling I am sensitive about this. I am. I’ve been fighting this fight for 2 decades, and at this point it appears to me that we have convinced all of the reasonable humans already. The rest are ineducable–or put another way, too cowardly to face the truth. As with every other existential threat humans have faced in the past century, the only ones who can save our pathetic species are the scientists, and as usual if we succeed, the thanks we will get is being called alarmists by the great unwashed we have saved. If we fail, we’ll be blamed by the likes of you.
Sean wrote: “the worst thing that has negatively affected global understanding of the importance of climate science and future risks was in fact Al Gore’s Inconvenient Truth.”
With all due respect, that’s utter nonsense.
Al Gore’s movie did not in any way “negatively affect GLOBAL UNDERSTANDING of the importance of climate science and future risks”.
On the contrary, by effectively and accurately communicating the current scientific understanding of anthropogenic global warming, Al Gore’s movie contributed powerfully to better “global understanding” of the nature, severity and urgency of the problem.
Your error is to confuse the delusions of brainwashed mental slaves of partisan Republican propaganda that has demonized and vilified Al Gore for over 20 years with “global understanding”.
In reality, the victims of Fox News who turn red-faced with rage and begin spouting crackpot conspiracy theories about the IPCC at the mere mention of “Al Gore” are actually a miniscule minority compared to “global” public opinion.
Comment by SecularAnimist — 22 Nov 2013 @ 12:16 PM
perceived consensus and political ideology … most strongly related [to respondents’ views on climate].
… AMS should: … acknowledge and explore the uncomfortable fact that political ideology influences the climate change views of meteorology professionals; refute the idea that those who do hold non-majority views just need to be “educated” about climate change ….
As far as contrarian arguments go:
I have found that most of the arguments (if not all) are simply “raising reasonable doubt.” The contrarians essentially do what a good lawyer would do in criminal court when there is no exculpatory evidence. And I have to admit, some of the contrarians have been doing this very skillfully.
Unfortunately (for them) reasonable doubt has very little weight in scientific research – because it shouldn’t. Oddly they don’t seem to understand that.
But reasonable doubt appeals very much to common sense intuition. And so it dominates the discussion – in the minds of skeptics – and seems to be a valid reason to reject global warming.
It’s not that scientists don’t communicate – they do – it’s that they can’t break through this barricade created by the contrarian’s reasonable doubt.

The problem with that is that the so-called “arguments” of the so-called “contrarians” don’t actually raise “reasonable” doubt. They just spout lies and nonsense.
A “lawyer in criminal court” would be held in contempt if his defense consisted of nothing but blatant laughable falsehoods, and accusations that the judge, prosecution, police, and indeed every law enforcement agency and judicial system in the world were all conspiring to frame his client:
“The prosecution’s case rests on multiple eye-witnesses and ballistic evidence which they claim prove that my client shot the victim — but ladies and gentlemen of the jury, the explosive properties of gunpowder are merely an unproven theory and what’s more the prosecutor is a liberal, and fat.”
The “reasonable doubt” argument relies on the idea that we shouldn’t make radical changes to our way of life before being absolutely sure. This argument fails in two important ways. First, we can’t be absolutely sure of anything in science. Second, not doing anything about our fossil fuel habits is highly likely to make radical changes to our planet’s environment. Turning the argument around, we shouldn’t continue to burn fossil fuels without limit UNLESS we can be reasonably sure that doing so won’t lead to significant harms. But, in fact, we can be reasonably sure that continuing on the present course will lead to serious problems in as short a time as 50 to 100 years.
“But reasonable doubt appeals very much to common sense intuition. And so it dominates the discussion – in the minds of skeptics – and seems to be a valid reason to reject global warming.” If a tidal wave seems to be approaching your house on the beach, does “reasonable doubt” suggests you shouldn’t move to higher ground unless you can be absolutely sure you will be swept away if you don’t?
@24 Ray .. “I’m gonna go out on a limb here and guess that you haven’t interacted with teenagers much.” Poor call there: Would father of 4 and a manager of McD+ more count? :)
“Dude, if an audience is not willing to entertain the message, it doesn’t matter how the speaker presents that message.” Totally agreed. imho Al Gore proved that people were willing to listen and they went in droves. People who go to Blogs for whatever reason are also willing to listen too. Problem there is they are manipulated via sophistry and don’t realise it. Once you lose those people they are gone. Some people who went to see Gore and accepted have later switched to believing the blogosphere and Monckton level BS instead.
I get your angry and frustrated. So am I. I am not your enemy.
So I will close on this good point of yours Ray point especially in regard one particular sensitive reply : “if an audience is not willing to entertain the message” … see you, it’s a waste of time here.
Would father of 4 and a manager of McD+ more count?
How about a State Training Manager role? How about being in charge of running all aspects of a $40 million per annum business 7 days per week with 900 staff and 90% of them under 25 years old? Just a glib passing comment.
The fact that different models produce different results is a good example of something that could be exploited to seed reasonable doubt. No, the contrarians don’t need to lie, a little bit of rhetoric will do the trick. That’s why seeding reasonable doubt is such a hideous tactic.
Comment by Retrograde Orbit — 22 Nov 2013 @ 11:51 PM
And I am going off topic here, sorry …
Seeding reasonable doubt to sink a scientific theory is not exactly brand new. The proponents of Creation have used it for 150 years to battle the theory of evolution. And they have been fairly successful – as far as public opinion goes. And I am worried the same will happen for climate change.
Comment by Retrograde Orbit — 22 Nov 2013 @ 11:56 PM
Yup. No concrete suggestions. Just, “Communicate better.” Great. Thanks.
A recent survey published in USA Today and elsewhere shows, to my mind surprisingly, that significant majorities in every surveyed US state–something like 45 of them–think AGW is real and want something done about it. That very little is done is, to my mind, thus not really a communication problem (a convincing problem) anymore. Yes, scientists and statisticians can always learn to communicate their knowledge more effectively and that definitely can help, but I think it’s mostly at the margins. The problems are power politics, money, and status-quoism, generally speaking. Thus I find this particular discussion in the comments section much ado about very little. (FWIW I’m never convinced by blog commenters referring to their own longtime experience as warrant for the veracity of their arguments, so I’ll refrain from sharing mine.)
@ 29 SA .. that argument of yours is as good as any on a climate science denier website. Full of holes throughout it. But to you, you’re a genius, with nothing left to learn. Therein lays the nexus of the problem. people who do not know how they themselves communicate telling others why their ideas and communication is all so wrong. Don’t go defending yourself in court, or taking civil law suits out on others. You have no idea about how a Court operates and how little reliance there is on ‘evidence’.
Retrograde Orbit, don’t waste your time, go back to lurking and using the site as a source only. These guys know it all already. That’s why the everything is going so smashing with the IPCC and UNFCCC and GHG cuts.
@38 Aaron maybe the recent US survey you mentioned is one I’m also aware of which I won;t bother giving a link to either. There are others of course by academics sources in 2011 and 2012 which paint a very different picture entirely. Which is more accurate requires more thorough analysis than a comment. A bit like GCMs perhaps? Not as simple as it may appear on the surface. :) And drawing conclusions from the latest news report and using that to suggest a pov is probably flawed by default is risky business. imho and ime.
Meanwhile what’s the reality? The IPCC process started 25 years ago now. What’s the outcomes on the ground today? Has the US ratified Kyoto or been able to lead the world to an even better global agreement yet? If any vote went to congress on Climate Change issues would it pass both houses? Has the EPA been empowered to monitor Shale gas/csg projects according to the Clean Air Act yet? Would that get through Congress or the media scoundrels? What actual position did the US take to COP19 in Copenhagen 2009 and now the meeting at Warsaw? These are the questions in my mind that count for more than the latest public opinion poll.
This is where the tyres meet the road. Theory is wonderful, so too positive thinking, as are thought bubbles and assumptions without solid evidence to support them bar an ‘opinion’ that well ‘it feels right to me.’
But luckily the IPCC formally did take on Lord Monckton publicly proved to all he was a flake who manipulated materials, lied through his teeth, had no basis for his claims, and destroyed his ludicrous reputation across the world as an intelligent human being interested in the truth of Climate Science. Oh, hang on. Sorry, I got that wrong. That didn’t happen because Monckton is still out there and pops up all over the world on radio talk backs shows and the Murdoch print media or Fox News where everyone makes fun of these deluded climate scientists … people just like Gavin, Rasmus, and Stephan without a word being said, and not one single press release in 25 years.
By saying “scientists and statisticians can always learn to communicate their knowledge more effectively” shows you are not really interested in the issue I raised. So i’ll leave it there.
Wotan and Way have been posting to Curry’s blog this week. I hope they know what they are doing. And don’t end up like a polar bear dancing on the melting arctic ice flows as a result.
Aaron when someone defaults to presumptuous rhetorical questions as a tool to put another down and dismiss their pov out of hand, one has a choice of ignoring it or responding. But when someone asks a question on a discussion board the first thing they should assume is that someone might just answer it. The response will likely follow the original tone and attitude of the question and how respectful and genuine that was. Had Ray been genuine I would have gladly emailed him life’s Resume. But of course that wasn’t the point was it? :)
I have been online since 1995 ie 18 years. I have a ‘little’ experience on Usenet and Discussion boards along the way. Very direct and confronting at times. But not always. I think I have a learnt a lot. One of those was to never make hasty decisions about others. Another was how to ask really good and genuine questions to illicit much needed information from others.
But that’s not all I learnt. Now that link I left as a gift. The author is a high grade academic with an excellent reputation. Richard King, look him up. But please whatever you guys do do not listen to the 1 hour interview nor read his book. I’d hate to hear about the impact of any cognitive dissonance such a step may cause innocent victims as a result of me sharing that URL. So best ignore that too, and I’ll just run along. Best to you, and yours. [sincere apologies for the length and wasted bandwidth]
That’s not what I mean. Above Ray said:
“and at this point it appears to me that we have convinced all of the reasonable humans already. The rest are ineducable–or put another way, too cowardly to face the truth”
That sounds like drawing a battle line: You are either with me or you are against me! If you are still on the other side of the line you must be against me! I stopped trying to convince you I am going to fight you now!
I understand Ray’s anger and frustration. But still, the drawing of battle lines is not helping.

Er, it’s when the lobbyists turn up at the science sessions — money, in large amounts, starts to be obviously spent — that yer battle lines are getting not just drawn but entrenched. That’s big money, coming out of the shadows.
Remember, it’s better to fund the controversy on all possible sides — that’s how you set scientists up to teach the controversy.
There’s no question of commercial importance that can’t be put off by a pious appeal to and funding of further research.
Unfortunately, mainstream media outlets are perpetuating the misconceptions. One way they achieve this is by granting outlier voices disproportionate visibility in the public arena, creating misleading and counterproductive debates. http://link.springer.com/article/10.1007/s10584-013-0704-9
In the survey of surveys was Q. “Warming is extremely important personally (and is likely to influence voting)”.
Here are the results for some the states, random sample. Nevada 12%, Florida 14%, Louisiana 9%, Alabama 7%, Montana 5%, New Jersey 12%, West Virginia 6%, New York 11%, Rhode Island, Delaware 8%, Michigan 8%. I could have looked at more but a pattern is emerging. (It looks more like the green vote?)
Something is going on in this survey behind the top line figures, I suspect that respondents are trotting out the “right” answers to the **motherhood** questions like “Global warming has been happening” but giving some more thought to those questions that require a more measured PERSONAL response.
This can be seen in the huge disparity (disconnection) between the strong agreement with, say, the question “Warming will be a serious problem for the world” [ ~70% ] Compared with the massive disagreement with the “Warming is extremely important personally” [ ~7-12% ]
These kinds of disconnects have been showing up in many surveys for many years, across all nations not only the US. imho.
You did not ask for any concrete suggestions. You merely sought to blame the current situation on poor communication by scientists. I’ve actually been meaning to write up some general guidelines for the public consumer of scientific information since the piss poor article in The Economist about how science is on the verge of failure. That article suffered from the same myopic view of how science works that you are demonstrating.
Part of the problem is that people view this situation in isolation. There is a very, very long history of scientists calling attention to potentially severe threats to civilization. They are invariably met with derisive cries of “Alarmist!” by laymen who have neither the acumen to understand the problem nor the courage to accept that it is real. When the scientists eventually come up with a technical solution and the problem ameliorates, the doubters take the resolution as proof they were right all along.
One of the first examples I can think of was the crisis near the turn of the 19th and 20th centuries when soils were becoming depleted of nitrogen. This problem was deemed sufficiently severe that Fritz Haber was given a Nobel in Chemistry for figuring out how to synthesize ammonia despite his later role as the father of chemical warfare.
Later scientists who called attention to the dangers of exponentially growing population were deemed with the same epithet of alarmist when the green revolution postponed the inevitable demographic catastrophe.
The ozone hole? Identical. You often see climate denialists trotting out this example as “proof” that scientists are lying to keep people in a state of fear. This was also a good example of industry PR lasting long after the industries involved had moved on.
The Y2K bug. Same thing. People claim it was overblown. I know for a fact how much work it took to fix it, because I know people involved.
The dangers of tobacco–this is the most direct analogue, since the denial industry features many of the same players. John Mashey has written extensively on the connections. It is also interesting to look at the connections and similarity of tactics adopted by the anti-science forces here and those adopted by anti-evolution/creationist movements.
In all of the late 20th century/early 21st century examples, there has been a concerted effort by spin doctors to erode peoples’ faith in science. And I am afraid that faith may be all science has to offer the crowd who are more concerned with the antics of the Kardashians and UFC/NASCAR than the real world.
Retrograde Orbit, your post reminds me of the observation that class warfare occurs whenever the poor become so exasperated that they return fire on the filthy rich. We are already in a war. If we don’t draw the battle lines, they will draw themselves.
Sean, I was responding to the idea that the reasons for public misunderstanding of the science ‘n statistics, and much more importantly, public inaction on climate change, belongs to bad communication on the part of scientists. I was trying to suggest that in the broadest terms, this seems now to be untrue and that the problems lie elsewhere. Your own most recent post all but confirms this (with some wiggles around the issue of “scientific consensus”). The percentage difference between those who think AGW is real and those who think it’s “extremely important personally” is huge, as are the two ideas themselves. This is not a problem for scientists communicating science. It’s a cultural/political problem, and in that instance it’s much more about dialogue and on-the-ground interaction between stakeholders than any abstract concern with scientific consensus, etc. (Poll your neighbors: I will wager two things: 1)a very large percentage of them will have an opinion on climate change. 2)a very small percentage of them will have even heard of the “pause,” whatever their opinion.) Communicating science is only one relatively small part of a huge mosaic of responses to the reality of the climate crisis.
Aaron wrote (#38): “That very little is done is, to my mind, thus not really a communication problem (a convincing problem) anymore. Yes, scientists and statisticians can always learn to communicate their knowledge more effectively and that definitely can help, but I think it’s mostly at the margins. The problems are power politics, money, and status-quoism, generally speaking.”
I think that is quite right. For the most part, I think “scientists and statisticians” have been communicating what they have to communicate quite well, and the constant overwrought agonizing about how to better communicate “the science” is misplaced.
The problem is that many people never even hear what the scientists have to say, because they are being drowned out by the massively funded bellowing bullhorn of the denialist propaganda machine and the deafening roar of pseudoscientific drivel, outright lies, slanderous hate speech and crackpot conspiracy theories that they call “reasonable doubt”.
And the job of that propaganda machine is made that much easier because most scientists seem reluctant to raise their voices much louder than a whisper.
Scientists don’t need to learn to “communicate their knowledge more effectively”, they need to learn how to shout.
… economic motives often drive non-precautionary business decisions. In virtually all reviewed cases it was perceived to be profitable for industries to continue using potentially harmful products or operations. However, decisions are also influenced by a complex mix of epistemological, regulatory, cultural and psychological aspects. For instance, characteristics of the research environment and the regulatory context can provide business actors with opportunities to enter into ‘political actions’ to deny or even suppress early warning signals. Also, business decision-makers face psychological barriers to awareness and acceptance of the conflicts of values and interests entailed by early warning signals. Cultural business context may further contribute to the denial of conflicts of values.
The chapter concludes with a set of reflections on how to support more precautionary business decision making. A prominent policy response to the conflicting interests of business and society is introducing regulations that attempt to steer business rationality towards internalising external effects. Innovative solutions such as assurance bonding should be considered.
There is a need to better understand and expose why business actors do not respond voluntarily to early warning signals with precautionary actions. Blaming business, in particular with hindsight, tends to be common reaction that may not always be constructive. It often misses the complex or even contradictory set of motives and drivers that business actors face.
Few people intend to be evil, most decisionmakers in business think they’re making rational economic choices under the rules they’re obligated to follow (e.g maximizing stock price in the short term).
Demonizing tends to increase the number of demons, duh.
And speaking of the topic, thanks to Rasmus for an opening article -loaded- with links to relevant useful interesting information about statistics-and-climate; seeing how many people are actively working at making us smarter about this, and seeing local and national as well as global information accumulating, is helpful.
Folks, read the linked pages. Lots of good science, I hope more of the scientists speak up.
@48 Ray, thx for the response there. I am not sure what others think about it, but from where I sit it pretty well confirms the basis of my own overview comments and key suggestions of the core issue re “communication’ is all about. So I’m at a loss why you believe you disagree with me. What’s the purpose of effective communication, and how does one know when it has been successful? (Rhetorical)
Now nothing I have said has been about ‘blaming’ anyone nor fault finding, but speaking to the reality as it is. eg you say ” You merely sought to blame the current situation on poor communication by scientists.” I did not. Ray I have checked my prior posts and word searched various pages, and only ONCE did I use the word “poor” and it was in regard poor word choices, ala semantics etc. If you or anyone else sees that as over the top “blame and fault finding” well, whatever. What is a comments page for? (rhetorical)
@50 Aaron. Most of my focus was/has been on the IPCC specifically and/or lack of any central ‘authoritative responsible’ body being active in the field of the public domain. I suggest you have not understood my meaning at all and are cherry picking aspects of it only, not the whole of it. and rather than making silly online “bets” you are right, how about reading up on what academic papers actually say about ‘public opinion and understanding’?
Skepticism, disinformation, and media hype is one thing. They do have an effect on others. Climate science communication is another. It too has an effect on others. BOTH exist within the same SPACE. To pretend they do not and that people simply need to read the IPCC Reports or RC is a joke and all is well with ‘communication’ is a joke. (isn’t it?)
UK Study 2011: *Scepticism and uncertainty about climate change: 1) Scepticism is strongly determined by environmental and political values rather than by education or knowledge. 2) Public uncertainty about climate change has remained remarkably constant since 2003, although BELIEF that claims about the issue ARE exaggerated has DOUBLED. 3) The paper describes a novel and highly reliable measure of public scepticism about climate change, the Scepticism Scale. http://www.sciencedirect.com/science/article/pii/S0959378011000173
UK Study 2012 Uncertainty & attitudes towards climate change – “In both groups, attitudes towards climate change became significantly MORE Sceptical after reading the editorials, but we observed no evidence of attitude polarisation – that is, the attitudes of these two groups did not diverge.” http://psychdemo.cf.ac.uk/home2/whitmarsh/Biased_assimilation%20pre-print.pdf
What is climate change scepticism? http://www.sciencedirect.com/science/article/pii/S0959378013001477
Role of the IPCC? IPCC is THE leading international body for the assessment of climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide THE WORLD WITH A CLEAR scientific view on the current state of KNOWLEDGE in climate change and its POTENTIAL environmental and socio-economic IMPACTS.
Because of its scientific and intergovernmental nature, the IPCC embodies a UNIQUE opportunity to PROVIDE rigorous and balanced scientific INFORMATION to decision makers. By endorsing the IPCC reports, GOVERNMENTS acknowledge the AUTHORITY of their scientific content.
Oslo, 10 December 2007 – The IPCC and Albert Arnold (Al) Gore Jr. were awarded the Nobel Peace Prize “for their efforts to build up and DISSEMINATE greater KNOWLEDGE about man-made climate change, and TO LAY the foundations for the measures that are NEEDED to counteract such change”.
It is now 2013 – 25 years post-IPCC being created, and 6 years since the IPCC won the Nobel Peace Prize. Judge the current RESULTS and OUTCOMES in the real wolrd right now today, and compare that with the *theory* and *goals*. Successful or not at disseminating greater knowledge, providing scientific knowledge, and SEEN AS THE AUTHORITY by ALL Governments and by ALL People? .. yes/no/don’t know. (rhtorical) Thx and Best
@51 SA “Scientists don’t need to learn to “communicate their knowledge more effectively”, they need to learn how to shout.”
If the message is being drowned out by denialist propaganda, and that is the reality, then Climate Scientists / IPCC / whoever need to deal with that reality and counter it with more effective communication techniques that work in order to achieve the desired results.
If shouting is the answer and it works, then that is being MORE EFFECTIVE in their communication style by default. Which is the complete opposite pov of “how to better communicate “the science” is misplaced.”
Either their is a lot of cognitive dissonance going on here or multiple mind mudhras or outright and irrational ** denial ** of what I have been saying. Best.
@26 Hank (btw I always appreciate your straight forward contributions with add-on info here for years)
OK, attempt to refute I will. I am aware of other studies similar to this one, and they too show similar conclusions. I don’t argue those conclusions. I agree with them because they are rational and reasonable. I have had some experience in internal “surveys” and understand the dynamics involved here to a fair level, not expert. Don’t claim to be. I express my opinion as best I can and will explain it or provide more info nuances if asked. No one has asked me a single thing in this direction thus far. No problem my end.
OK I’ll stick with the summary on the page linked: “refute the idea that those who do hold non-majority views just need to be “educated” about climate change;” I don’t refute that, there’s a lot of truth in it. However I claim it is misplaced and off-base. Do not conflate “education” with “communication” – they are not equivalent. If this needs explaining then I suggest people should Google scholar it.
re: “convey the widespread scientific agreement about climate change” is another good conclusion in the survey I agree with. This truth extends across the public sphere as well. It’s a core issue. Way too many believe there is limited consensus, when the opposite is the truth.
One recent public poll/study I saw (by memory) only 7% were found to be profound non-AGW sceptics (others had some doubts). When asked how many others were skeptics they said 47% would be. When asked what was the scientific consensus they believed it was 50/50. iow they totally rejected or did not know about any of the studies putting the scientific consensus for AGW/CC risks at ~97%.
You and others seem to be only “blaming” the denialists for this. Why?
May I use an analogy instead of “data”? 5 people over several years come to my son denying I am his father. When he comes to me each time and asks, I refer him to the documented “data”, his birth certificate listing me as his father. I do not discuss it further. I refuse to get a DNA test done. Why? Because even a DNA test may only be 97% accurate anyway.
The 5 people have seeded him with compelling doubts to a point where he does not believe me, and yet still I stay silent. he asks intelligent questions and yet still I refuse to say a word about the 5 people falsely accusing me of not being his father. I know these 5 people, and I know what they are like, and they know they are wrong, and yet still I say nothing about them and ignore my son and do not instigate direct communicate with him about what I know to be true and know to be false. Why should he believe me?
It’s been proven scientifically that eye-witness accounts are more often than not unreliable, even when honestly believed by the witness to be true and accurate. Research it.
Here’s two examples of the efficacy of the law courts getting it right (especially in the US) Hurricane & O.J.
Surely you don’t need more examples? Nice theory. It has manifold flaws in it and provably so. It’s all about who wins the “debate”, the “rhetoric” and the sophistry in the court room. Until you brought in “plea bargaining” which essentially has knee-capped your Justice system. Plus a ton of unconstitutional and unethical irrational laws. :)
> lack of any central ‘authoritative responsible’ body being active
Name one case where that’s worked out, for any global problem?
These things are solved by people cooperating, to the extent they get solved.
Look again at that ‘Late lessons from early warnings’ documents; the first book didn’t discuss climate change at all, explicitly because of the uncertainties. The new second volume does, because there’s more known.
Look again at the discussion of beryllium disease — a modern example of the industry lawyer lobbyist lies and deception approach to a problem, quite clear.
>You and others seem to be only “blaming” the denialists for this. Why?
I don’t blame the poor stupid credulous copypasters for being what they are: easily misled and easily exploited. Because I’m aware people are like that. We fall for this sort of bogosity all the time.
Look at the Climate Reality project again, at the rate it’s growing. Those folks are working with the real problem, with presentations that are being improved — and fact-checked by scientists.
If we solve this, it’ll be their presentations that accomplish the change.
If memory serves (which it often doesn’t for me) this topic of communication became a sore spot a few years back. There is a tendency toward clumsy assessments or outright blaming-the-victim which trolls discovered could be used to derail conversation. Ironically, though the trolls have moved on to other stratagems, conversations are still getting derailed by default whenever the topic arises.
On the one hand, it’s a knee jerk reaction, on the other nobody wants to give trolls an opening. It’s unfortunate, but bottom line, if you want to discuss communication here, adjust your language accordingly in order to communicate about it.
But — Sean —
you’ve taken over a wonderful science topic that’s worth us learning from.
Could you take your issue and those attracted to it somewhere else?
Because the Statistics and Climate thread could still be about statistics and climate.
I’ve read about half of the links in the original post and mean to read them all and try to learn about statistics and climate. Here, if possible. Now, with luck.
Education starts with us, here.
If we’ll shut up long enough for the scientists to educate us.
Challenge: list the links in the original post.
Read them, check them off your list.
Ask smart questions showing a beginner’s understanding of the statistics.
Better yet, let’s hope some actual statisticians wanting conversation with the climatologists show up and ask better questions.
Give them a chance. Better places for offtopic stuff are plentiful.
Education, available here, is damn rare.
Sean: “The responsibility of being clearly understood is totally upon the shoulders of those wishing to communicate something from themselves to others. Until that is improved doesn’t make much difference how good or accurate the science is.”
Does that paragraph sound familiar, Sean? It is what you wrote back in #17. It is also simply flat-assed wrong. Communication by definition involves a sender and a receiver. Both have to work if the communication is is to be successful. Yes, a speaker can pitch his presentation incorrectly for his audience. However, an audience that is lazy or unwilling to hear what the speaker has to say will also torpedo the process.
Sean: “imho, the worst thing that has negatively affected global understanding of the importance of climate science and future risks was in fact Al Gore’s Inconvenient Truth.”
And then you come up with some vague suggestion that the IPCC should have made AIT rather than Gore. As if the chuckleheads whose oppose Gore find a UN panel any more credible. Gore had been making the same presentation for years. A documentary maker merely decided to film it. Now at any point during those years, a Republican politician could have stood up with Gore and depoliticized the topic. Did they? Nope. At the same time, scientists all over the world were also giving popularized talks on climate change. Ask Jim Hansen if his expert status saved him from accusations of “political activism”.
Sean, my criticism of your position is that you are criticizing those who have been most active for the longest in getting the truth out there rather than those funding and running the lie machine of anti-science. And what is more, you are criticizing people who are trying to popularize the science on their own time even as they try to come to a better understanding of the frontiers of climate science in their day job.
I would suggest that rather than making scientists take time out from their important day jobs to refine their presentations to the point where even the most blinkered imbecile cannot understand them, we might better expend some effort getting the average lay person to better comprehend how science fricking works. I contend that this would pay benefits not only for climate science, but would also benefit the lay person by making them a better consumer of medical research, safety research, etc.
I contend that the problem is not with what scientists are saying but rather with the public’s inability to comprehend what real science sounds like and how to distinguish it from the blatant and transparent crap dished out over at WTFUWT.
@59 Radge, thanks for your comments again. Much appreciated. I hear what you are saying. I’ll simply state that it is intentional with each step shift dealing with the reality of what comes back.
Despite the fact that my basic pov/idea is going over people’s heads, that in itself is actually proving my point. I am saying what I say and the form that I write it for a rational proven reasons. Damn it is annoying though. Is my communication effective relative to purpose? Well that depends on how one looks at it. I say yes it is.
There’s an assumption (actually at least 10+, but to keep it short) being made by all that an improvement in communication by scientists would be able to sway entrenched ‘sceptics’ to a scientific view of the evidence.
What one should, could, might be able to see here now (per the reactions) is the exact same dynamic utilised by denier website to deny what is actually being said and twist it into sometime else entirely. It’s human nature. Next step is Gavin shipping me off to the bore hole. :) which is fine by me, it’s his website.
[Response: I moved your posts to the open thread because they were (are) off topic. Please continue your discussion there. -gavin]
And there is no point speaking to people to do not wish to listen or remain open minded enough to consider they may be mistaken about their initial reactions and the subsequent effects that come from that. Nothing exists in a vacumme.
I’m merely planting seeds. A gardener will show up one day and the penny will drop. I have nothing to prove. I don’t live by others agreeing or fawning over me, nor laying garlands at my feet that I am right or brilliant. :) Best.
“It may be worth further simplifying your perfect weather/climate definition, now to say that a series of weather events makes up a climate, and climate is defined as a group of weather events.”
I don’t think it’s worth it – on one level your definition is a tautology (since the climate IS the sum/average of all weather events) and on another level – quite a counterproductive one, because it obscures important differences between climate and weather – that both forcing and predictability of climate and weather are very different. Let me explain:
It is my understanding (and if I am wrong I would welcome setting me straight) that weather is very sensitive to chaotic processes, while in climate much of this individual variability of weather events simply “evens out”, thus filtering out the signal of chaotic forcing and leaving a more predictable signal of underlying fundamental thermodynamic forcing. So when you write:
“I have been shocked to hear meteorologists publicly address the issue and apply the 30 year rule to define a changed climate”
I’d suggest that the reason for this “shocking” practice may have a very good reason – the “30-year rule” filters out (all? most?) of the chaotic variability of weather events, as well as short-term fluctuactions (El Nino/La Nina cycles + perhaps part of the decadal variability). As a result, what’s left behind should be the long-term change – i.e. tha what we area after when discussing “climate” change. Your disapproval of this practice and promoting instead the definition of a climate as a simply “series of weather events” seem to obscure this reality.
The filtering out of chaotic events has also other serious implication: improves the reliability of predictions. Again, you definition obscures it, and by doing so, plays into a frequent line of argument of climate change denialists, who say that if scientists can’t predict the weather 2 weeks from now, how on Earth are we to believe them when they make predictions about climate 100 yrs from now. To which I answer that I have no idea what temperature will be in my town on, say, February 15 (weather), but I am pretty sure that it will be lower than on July 15 (climate) – and I can plan accordingly (e.g. inviting my friends for a BBQ on July15 instead of February 15). The definition of climate as a simply a series of weather events – obscures this reality too.
To sum up – I don’t see any upside for your redefinition of climate as series of weather events – as a tautology it does not bring any new insights and only downsides – obscuring the important differences in forcing and predictability between climate and weather and by doing this opens itself to be used to mislead the public by the people of bad will.
(If I have made errors in my assumptions, I’d appreciate pointing them out to me)

“Dear Dan, thx for the question. The increases in global avg mean temps are in fact NOT directly tied like a multiplication table to CO2 ppm in the atmosphere. The system is far more complex than that. Please let me explain a few of the variables involved – CO2e is only ~50% of the AGW forcing, on top of this factor there is land use, forest clearing, concrete use and much more involved in driving up Temps. Also CO2 itself is only ~50% of the total GHGs ie CO2e AGW forcings. There are time lags with the climate system responses plus natural variability on top that which is is undefinable. There is ~90% of excess heat being absorbed by the oceans that does not show up fully in surface temps measurements. There are regions not covered by accurate temp data collections and thus those areas ‘modeled’ on estimations. Given all the above and more, one cannot take a view of a *direct co-relation* being present for atmospheric CO2 levels and Surface temps as measured. Does this help clarify the situation better for you? Feel free to ask more questions and I’ll do my best.
