Scientists Need Attitude

The mass psychology of climate change - scientists need 'attitude'


Brian Davey, 2 December 2009

I am sure that there are a good few scientists who have got into studying climate change, thinking, as one CRU academic put it, that "the science speaks for itself" and really wanting to stay out of the increasingly bitter dog fight with all the rubbish repetitively thrown at them by climate change denier. The CRU storm and the dirty tricks used shows, if it wasn't clear enough already, that staying outside and above the mud fight is a forlorn hope.

Whatever the scientists want they cannot avoid that the science is deeply unsettling in its implications for everyone on planet earth, for every parent of a child because of what it says about their future, for every business whose production involves a huge amount of carbon energy in its input and particularly for businesses which sell carbon energy. It is patently obvious that millions, perhaps billions of people would prefer not to believe the climate science - and for these people climate scientists appear to be the bringers of thoroughly bad news.

Does not everyone knows what happens to people who bring bad news? If they don't they are lacking something in their education.

Ibsen's play

According to the Guardian, staff at the CRU have now received personal threats. The police have been asked to investigate. Ibsen pictured an almost identical situation just over a hundred years ago in his play An Enemy of the People. The chief character, Dr Stockmann, is dismayed to find that when he identifies that contaminated water from the towns tannery threatens the health of visiting tourists who might go to recently developed spa baths he is attacked by all and sundry - because of the financial ruin that closing the spa baths will bring upon the town.

While climate scientists get the police to defend their personal safety perhaps it is worth thinking about how they are going to defend themselves intellectually. For it is too innocent to believe that they can just "let the science speak for itself" against the thunderous clamour of a carbon-money based PR machine which bases itself on the wish of a large part of the public to look away from the reality of an exceedingly unpleasant future.

In this regard let us start with the observation, which ought to be obvious but clearly isn't, that the science can only "speak for itself" fully to other scientists operating in the same peer group. To the overwhelming majority of the population the science doesn't speak to them at all - they can't make head nor tail of it.

Indeed we can go further. This very unwelcome set of messages is probably perceived by many as coming from those kind of people who they think they remember from school - who rather than caring about enjoying themselves, who instead of being normal and caring most about sex, drugs, rock and roll, football and fashion, spent all their times in their bedrooms swotting and thought rather too highly of themselves for being clever - geeks and anoraks in fact, kill-joys. To this group of people the science says these people are still kill-joys.

Let me give a deeper explanation of where some of these kind of intense emotions come from. Every one of us has the experience when we grow up of "feeling small" when we are small - and particularly when in the presence of somebody who " knows what is in our best interest ". All the way through life we put ourselves in the hands of people who have an expertise and knowledge that we do not have - because it is quite impossible to know everything. Frequently, moreover the fact that other people have knowledge that we do not have puts us in the position of having to follow their advice, or even their direct instructions or orders. For a lot of people this is problematic emotionally when it re-awakens the feeling of being made to feel small. It triggers an exaggerated sensitivity about their social status and powerlessness. It is out of this that being patronised and condescended to is so emotionally tricky. There are situations where we have to act on advice where we feel unqualified to evaluate it and this leaves us uneasy - even worse if "the expert" pronounces in an insensitive fashion. This can easily reawaken our childhood feelings of humiliation, condescention, inferiority and powerlessness.

Now it is true that when scientists tell us "what we have to do" in regard to climate, they are, of course, not telling us what they personally want us to do but what nature, as shown in the science, requires us to do. This is completely impersonal. But that is not how it may feel at the emotional level for some people.

The traffic warden may also be telling us completely accurately what the parking regulations say - and that makes it particularly galling for some people. After all, compared to the exceedingly important person that I am, this person, this parking enforcer, otherwise has no status at all and certainly would not normally be the sort of person telling me what I can do.... (I'm trying to get into the attitude here, dear reader - in fact I don't own a car and have never had a parking warden hassling me about where I lock up my bike.)

Now let us think about this in relation to climate science. Time was when the important people who set the big agendas were entrepreneurs, economists, senior officials, senior politicians - then along come these people from the universities backing up what the eccentric greenies were saying. And what these climate scientists say is not only a nuisance and an inconvenience to business as usual - suddenly the economists and politicians and business people are being told that they need to dance to another groups agenda, to make radical adaptations to how economics works, to set up new policy frameworks, adopt ideas that cramp the previous freedom of action newly won by the free marketeers - so does it surprise that this creates resentment? Does it surprise that these scientists are felt to be on the make - to be after influence, power, research grants... their right to tell "us" what we should be doing.

To many people the fact that scientists - belonging as they do to the social group I identified earlier - are telling us what is required of us is not something that they are going to accept just like that! It's not just the elite that might start to get pissed off by all these green tips that the tree huggers want when they tell us how we should start living differently.

This thought was sparked in my mind when an acquaintance wanted to recruit me to what I personally think of as an odd medical idea and described her motives partly as being "subversive " in relation to the medical establishment. The idea that one might come across some very simple notion which has not occurred to all the medical scientists is appealing - despite all their clever knowledge and training ordinary people "with common sense" can make up their own cures - this would certainly "put all those clever doctors in their place".

Now the point about these resentments and emotions is that while climate scientists are playing cricket and "letting the science speak for itself" the PR and advertising agencies, the spin experts and many politicians understand these issues of mass psychology intuitively and play them very skillfully.

When they do so they also connect up to may people's money worries. We live in a society where the mass media constantly tells us that success is to be measured by how much we are able to buy, to consume. At the same time it is usually stressful and difficult for most people to actually earn the money to buy and consume at the level people are told they should aspire to. Parallel to all this the people running businesses are trying to make as much money as possible. Then along come these scientists, wearing wooly jumpers and camping in fields near power stations and the governments starts to accomodate the ideas of these wierdos - in order to tax away all our hard earned money.

Of course the idea that climate change is a scam for governments to tax people more is rubbish - but what this oft repeated mantra shows is what is uppermost in many peoples minds - money. This is part of climate change denial too.

Climate change denial thus contains a good dollop of bloody-mindedness against the "know whats best for yous" - including not only those clever scientists but the governments who think they have the right to take "our" money away from us and "think they know better than we do" how it should be spent - in this case on that "climate mitigation nonsense" that scientists gabble on about.

I suspect then that many climate change deniers are deliberately hooking into this notion of "the common sense of the ordinary man and woman" which trumps head-in-the-clouds science - as well as their prevalent monetary worries. There is a deeply rooted anti-intellectualism here, created by the emotional dynamics that arise in a society in which both knowledge and money are power. In this case the fact that we are dealing with science that is not even addressing a clearly visible current problem but something that scientists and politicians say will happen decades in the future adds a further twist. Climate change becomes an ideal target for rabble-rousing journalists and fringe politicians to whip up and play on a particular mass emotional complex. This is not just denial pure and simple, it is contrarianism - where "to be contrary" is both an intellectual and an emotional response of rejection. This is a topic which many people understand in a way which is emotionally structured by a toxic mixture of inferiority complexes and money worries.

So, what is to be done about this? Well, for a start we can notice that there is more at work here than just denial. We are also dealing here with some complex psychology, giving rise to some rather nasty emotions: a compensatory hatred which allows people to feel secretly that there are, in fact, superior to these scientists in their understanding - even though they, the scientists, have spent years studying the issues while the deniers have read two articles about grapes growing in the medieval warm period, seen three television programmes and have become instant experts.

Almost all of these amateur experts when confronted with real expertise and authority in their lives - for example when they go to their doctors - wouldn't say boo to them, but will do exactly as they are told. The flip-side of an inferiority complex is that people are actually very sensitive to being made aware that they hardly know a thing - so the correct approach for climate science is to rub the noses of the sceptics in their own ignorance.

So climate scientists have to stop thinking that the science will speak for itself. They have to stop playing cricket. If we want to use a sporting metaphor, they have to start playing rugby. This is well expressed in a recent posting at the GreenFyre blog that followed the CRU revelations which called on the scientists to go on the offensive by aggressive questioning of the sceptics. The aim of this exercise is to reveal the shallowness of their attack:

Which studies were compromised, how? be specific. Cite papers and data sets. What is the evidence? where is it? what work is affected? how? show me the evidence that says so.

This supposed scandal involves perhaps a half dozen people, how does it affect the work of the 3,000+ others who’s work makes up climate science?

How does it affect the work that was done before the alleged culprits graduated from university? the work from before they were born?

Of the 30,000(ish) studies that make up climate science, which ones are undone? where is the evidence? be specific … show us exactly how and why?

You are certain it topples climate science? how? where? which studies? what evidence? You don’t know? then how are you certain?

Please run through a list of the studies you believe are affected? Hockey stick? what’s that? please refer to specific papers and studies.You don’t know? then how can you be certain?

Ahhh, Soandso 2004? so just how is it compromised? what part of the work? I thought you were certain?


This suggestion puts it very well: climate scientists have got to learn "attitude". Otherwise the PR industry, funded by carbon's vested interests, will continue to make mincemeat of them.

Kloor Calls Me a Hypocrite

I've got a bit of a soap opera on my hands here. I'd appreciate some advice.

I suggested to Keith Kloor (#46) that he ought to mention the bizarre anomalies of 2010 on his blog:
Keith, it is hard for me to take this enterprise seriously if you don’t find space for some talk about what is happening in Russia, Pakistan, China and the eastern US this summer.

The situation on the ground has changed in the last couple of months, folks. You’d think that might have some effect on the argument.
Keith deflects this (#48) by making a similar challenge to me:
No, let’s talk about adaptation. Michael (46) writes:

“The situation on the ground has changed in the last couple of months, folks. You’d think that might have some effect on the argument.”

Well, for the sake of argument, let’s say you’re right: that these events you refer to have a AGW fingerprint. Well, realistically, you must know that this doesn’t change the other facts on the ground: that fossil fuels will still be the dominant source of the world’s energy for the foreseable future, even if tomorrow China, India, Russia and the U.S. all agreed to curtail their carbon emissions.

So where does that leave you with your high-minded concerns for the people of Pakistan, Russia, etc? Surely you’ll start arguing forcefully that we should start to pay equal attention to adaptation, in order to mitigate future suffering that is bound to come from more AGW-related floods, fires, and heatwaves?

Can I expect this to have some effect on your argument? Can I expect you to talk more about adaptation?
I responded to his request (#59) as follows:
Regarding adaptation, a few points.

Adaptation is crucial. It is necessary, but it is not sufficient.

As Eli says, “no adaptation without mitigation”. Without mitigation, the size of the disruption we are adapting to grows without any meaningful bound. If we are determined to get to the worst case, it will be pretty much the worst.

Adaptation is relatively local and relatively short-term. Mitigation is global and long-term. So we don’t need to talk about century time scales for adaptation, nor do we need to talk about global policy alignment and international governance.

A given level of climate change will have a larger effect in poorly governed countries than in well-run ones. Russia is as rich as, say, Chile, which responded very effectively to a recent (albeit nonanthropogenic) disaster. Russia has little tradition of effective local governance, and a long history of environmental neglect, and it is showing. I don’t think anybody is saying otherwise.

Wealthy countries are not immune, especially if they neglect infrastructure as if they couldn’t afford it. (That’s the real lesson of the arguably entirely natural Katrina, isn’t it?) See recent comments by the governor of Iowa “This is the new normal”.

While some polities are better at optimizing good times and others are better at preparing for bad times and others are good for nothing at all, there is plenty of precedent for adaptation at the regional scale. We know, intellectually and practically, how to do it, even if some of us chose not to.

We have no comparable skills in making global decisions. Mitigation, after all, is just adaptation writ large; adaptation that won’t work unless everybody cooperates. So adaptation is just ordinary, local politics and should be discussed in locally focussed fora. In large countries like the US, or at the international aid level, there are perhaps some issues about cross-subsidies, but while important, they are not qualitatively dissimilar from disaster relief and infrastructure assistance issues in the past. Mitigation, however, presents new and urgent difficulties which require changes in how the whole world operates.

There is a cliche metaphor about adaptation without mitigation: deck chairs.

In short, adaptation and mitigation are not a tradeoff. They are two faces of the same coin. The longer mitigation is delayed, the more mitigation will cost and the more adaptation will cost. But most adaptation discussion needs to focus on particular regions and particular vulnerabilities.

None of this makes the present hemispheric meteorological configuration any less weird. This is, arguably, not “weather” in the ordinary sense. It should cause people to rethink their opinions.

I for one feel very differently about the situation now than I did a few weeks ago. A few weeks ago I thought “major impacts in the future are very likely”. Now I think “major impacts have very likely started”.
Really, I thought that was fair and responsive and pretty useful. So, since I responded (I thought reasonably and responsibly) to his challenge, did he respond to mine?

See for yourself. He responded with a top-level article, mostly about what I take to be some imaginary version of me, called The Ethical Hypocrites. He summarizes my response (he links to exactly the text quoted above) about mitigation thus:
Tobis countered with the typical zero-sum talking point, that mitigation (curbing carbon emissions) has to take precedence over adaptation, and that in any event, adaptation was largely a local matter.

This is the standard argument from climate advocates, who believe that encouraging talk about adaptation will undermine the urgency that should be paid to mitigation. Thus, the emphasis has to remain on mitigation, they argue.

But now that climate advocates such as Tobis are asserting that climate change has arrived with a vengeance, with tragic human consequences, I’m wondering: is it not irresponsible and unethical of them to play down the need for adaptation in order to keep the focus on mitigation?
Is that a fair summary?

Did I really "play down" the need for adaptation?

I'm happy to discuss any of the points here. I can imagine somebody thinking I am wrong about this, but I'd really like some insight into how someone would see what I said as hypocritical.

At first I thought Keith was being defensive, just trying to avoid the factual questions about 2010 as entering a new phase in climate change. But he seems bound and determined to accuse me of something now; that seems more than just ducking the question I asked him. I wonder what this is about.

Pakistan Versinkt

Pix of Pakistan flooding here.

Here's a map via BBC I've seen in several places (what an elegant palette...):



At first glance I thought that was flooding in meters, but no, it is flooding in million cubic feet per second. This is about double the normal outflow of the Mississippi, according to Wikipedia, or about 12 times the flow of the Rhine, or for Westerners, about 4000 times the normal discharge of the Rio Grande. More to the point, it is about four times the normal discharge of the Indus river itself.

The population of Pakistan is over 130 million. Some estimates are saying that 12,000,000 people, or almost 10%, are directly affected by the flooding. This is more than the entire population of Belgium, Sweden or Greece. Or Ohio, or Ontario, or Washington and Oregon combined.

The Russia Thing


what climate change looks like (BBC)

I am not sure how to take being definitely regarded as climate scientist by both Roger Pielke Jr (who is in and out of the Tobis-ooh-scary club) and Brad Johnson (an associate of Joe Romm), but not quite so definitively by anyone commonly regarded as a climate scientist. I suppose I should accept it as better than nothing. But Johnson's topic is worth following up. And I really liked that he got an actual meteorologist to back me up:
Like Dr. Tobis, Carver [Meteorologist Rob Carver, the Research and Development Scientist for Weather Underground] believes that manmade global warming has fundamentally altered weather patterns to produce the killer Russian heat wave. “Without contributions from anthropogenic climate change,” Carver said in an email interview with the Wonk Room, “I don’t think this event would have reached such extremes or even happened at all”:
I agree with Michael Tobis’s take at Only In It For the Gold that something systematic has changed to alter the global circulation and you’ll need a coupled atmosphere/ocean global model to understand what’s going on. My hunch is that a warming Arctic combined with sea-surface-temperature teleconnections altered the global circulation such that a blocking ridge formed over western Russia leading to the unprecedented drought/heat wave conditions. Without contributions from anthropogenic climate change, I don’t think this event would have reached such extremes or even happened at all. (You may quote me on that.)
Cool. Thanks for taking the heat, making a stronger claim than I did, Rob! And thanks for the work on this, Brad!

I want to explain my thinking in some detail on this, but I really don't have the time to do it justice right now. Of course it will be half-wittedly nitpicked and mocked to oblivion if I post it on a blog whether it's brilliant or foolish. I wonder if it rates a real paper somewhere. That would be a novelty...

But a short version occurs to me. Remember when I tried to explain that "global warming" and "anthropogenic climate change" don't mean exactly the same thing? Well, the fact that we now have situations like this one, and last year's in Australia, allows for making the point clear with some examples.

See, what we are worried about is not global warming. Global warming itself causes relatively little damage, at least at first. What we are worried about is climate change.

Anthropogenic global warming does not cause climate change.

Anthropogenic climate change causes global warming,.

Global warming (at the surface, just like global cooling in the stratosphere) is one of the more predictable symptoms of anthropogenic climate change. But if you change the forcing, you change the response. That's not a very deep scientific result, is it?

"Anthropogenic climate change" - well that's a tedious mouthful, isn't it? Not in a sense, no, not really. Not as tedious as what is happening this instant in Pakistan and in Russia, anyway. That's what abrupt climate change looks like.




Update: Tamino weighs in with a compelling graphic.



Update: Fire and Rain, a climate change anthem. Good call, Gareth.

Suzanne, the plans you made put an end to you.

A Moderate Approach to an Extreme Problem


Well, there are spectra of opinion, but let's go with the three bears approach.

First, you can believe that the risks of anthropogenic global warming are trivial, consequential, or vast.

Second, you can believe that the social changes required to solve sustainability issues are trivial, substantial, or fundamental. The libertarian believes that the changes are trivial, and will be borne by the marketplace without direct intervention. The radical environmentalist believes that the modern attitude is irreparable, and sustainability is an existential social question as well as an existential environmental question. The moderate view is that some adjustments are needed.

These are separate questions. Your opinion on one should really have no bearing on your opinion on the other. That leaves nine possible opinions.

More to the point, they are different kinds of question.

The first is not a question of political philosophy at all. It is simply a question of fact; the dominant questions are physical, chemical and biological. It is not "radical" to believe that the risks are severe, nor is it "reactionary" to believe that the risks are trivial. It's pretty much either right or wrong.

I believe the risks are severe.

The second is a question of political philosophy. Can the modern, post-Soviet, market-oriented worldview survive as is? Does it need some adjustment? Or must it be scrapped altogether. Here, I think the labels of "radical" and "reactionary" are quite appropriate, and this is where the dangers of immoderate beliefs lie.

I am a moderate. I think we can find our way through this without huge disruption to our culture, which has much to say for itself. I think the risks of extreme cultural change are real enough. History teaches us that absolutism is a great risk itself.

But I think it's obvious, looking at the evidence, that carbon emissions must stop. (Update - In response to comments, I mean here NET carbon emissions. As Arthur put it in a recent message, the carbon either has to stay in the ground or go back in the ground. We cannot use the ocean as a carbon dump.) I find myself being cast as an "extremist" for saying this in public discussion, even though it's pretty much what the entire expert community believes. No. After decades of gross neglect, the problem has gone from manageable to extreme. But it's not "extremist" to say so.

In short, I think we can preserve the modern western freedom and most of the prosperity, and indeed make it better in some ways. It's not automatic. It won't be easy. I don't think we can afford a revolution any more than we can afford the status quo. We have to fix our creaking, out of date and out-of-touch societies to be in touch with the world around us. The next century will, hopefully, not be as awful as the first half of the last one was, but we'll need to be very smart to avoid the future being much worse than what we have had recently. We can preserve individual freedom, a functioning marketplace, and collective security while eliminating extreme poverty, just as we always intended. But we have to work at it.

That's a centrist, middle-of-the-road position. It's just the problems that have, from thirty years of neglect, gotten extreme.

Update: Check out Andrew Sullivan on the liberal/conservative divide. (Yet another hat tip to Scruffy Dan here.) A correspondent writes the following very interesting reflection:
Is it possible that, at this level – the principled, humane, calm, smart, broad-minded, pragmatic, courteous, inclusive, reality-based level – there really is no difference between conservative and liberal? That once having ascended the peak to actual, functional intellectual, emotional and spiritual adulthood -- to human maturity -- the paths of liberal and conservative meet, as they say all spiritual paths do?

Maybe we are all both conservative and liberal all along. Ask yourself: if you won a new car on some game show, but could only have one of the following two options, which would you choose – brakes, or an accelerator? The answer, of course, is every car needs both, just as every person, and every polity, needs both brakes (conservatism) and accelerator (liberalism) – and hopefully, both in good working order.
The only thing I might disagree with is which is the brake and which the accelerator, these days. The words seem to me to have lost much meaning beyond a sort of cultural cohesion.

Whitehouse Speaks on Necessity of Scientist-Advocates

No, not that Whitehouse, this one:


via Why Sharks Matter on Southern Fried Science.

The link leads on to three nice related articles, of which this one is my favorite. John Fleck will probably like it too, since it mentions John as exceptional, something I agree with.

It argues against the Pielkian point of view,
Ultimately, politicians are useful [to conservation] because only they can make the important policy changes required to make the conservation movement’s goals a reality. However, they won’t do this unless there is overwhelming support from the public- the kind of support that merely publishing papers and speaking at conferences cannot possibly generate.
as does Senator Whitehouse:

The Beeb Apologises


Hallelujah! A first glimmer of responsibility from the mainstream press.

Professor Trevor Davies, UEA’s Pro Vice Chancellor for Research, received a letter, as reproduced below, from Mr Stephen Mitchell, Deputy Director and Head of News Programmes, BBC News.
Dear Professor Davies, firstly I should apologise once again for the delay in this response to one of the matters you raised earlier this month when you visited BBC News. I had promised to get back to you more quickly than in fact proved possible, given that several people involved in the edition of the Today Programme last December proved difficult to contact and our own archive of a programme broadcast seven months ago proved less reliable than I had hoped !

However I can now share with you the results of my investigation into your complaint about a sentence in a John Humphrys introduction to an item in the Today Programme on December 4th last year.
At 8.10 am, after the 8 O'clock news bulletin had ended, John Humphrys opened a discussion on the so called "Climate Gate" affair as follows:

"The theft of a few emails from a relatively obscure university in East Anglia is threatening the future of the planet. And if that sounds like the plot of a bad disaster movie ... well, suspend your disbelief for just a moment. The facts are that the emails were stolen and they revealed that some researchers in the university's Climatic Research Unit had been distorting the debate about global warming to make the threat seem even more serious than they believed it to be. It is also the case that the mightily influential United Nations intergovernmental panel on climate exchange regards this as so serious its head has announced that it will investigate. Where we enter less certain territory is what effect all this will have on attempts to fight global warming by those who believe it really DOES threaten the planet. Not that everyone does. Phillip Stott, emeritus professor of biogeography at London University is sceptical and he's with me. I'm also joined by Jonathon Porritt, the founder of the Forum for the Future and former environmental adviser to the govt .But first our Environment Correspondent, Richard Black:"
The first thing to say is that
the sentence : "The facts are that the emails were stolen and they revealed that some researchers in the university's Climatic Research Unit had been distorting the debate about global warming to make the threat seem even more serious than they believed it to be" is incorrect. For that I apologise wholeheartedly on behalf of the Today Programme.
There's considerable hemming and hawing after that, which you can see here, but at least we have this much. That's a start. Will we ever get as much from the New York Times?

Thanks to Big City Lib for the tip.

Moscow Doesn't Believe in This


Moscow has been as hot as Texas for a month. I keep looking at the forecast and it keeps looking like the forecast for Austin. This is wunderground's forecast as of 2:45 PM my time on August 7 2010 (19:45 UCT I believe)



Of course, there are several reasons that 100 F (about 37.8 C) in Moscow is much worse than 100 F in Texas. Here in Texas it is not uncommon; hence both biota and people are used to it. We have air conditioning and heat-hardy plants. Moscow sits surrounded by areas that are normally wet, cool, clammy bogs, but now are dried out and fire-prone.

It's around midnight in Moscow. The current conditions are listed as 82.6 F (28.1 C) and "smoke".

Normal July high temperature is 73.8 F (23.2 C); August's normal high is 70.3 (21.3 C).

Are the current events in Russia "because of" "global warming"? To put the question in slightly more formal terms, are we now looking at something that is no longer a "loading the dice" situation but is a "this would, practically certainly, not have happened without human interference" situation?

Can we phrase it more formally? "Is the average time between persistent anomalies on this scale anywhere on earth in the undisturbed holocene climate much greater than a human lifetime?" In other words, is this so weird we would NEVER expect to see it at all?

There are two approaches to answering this question. One is statistical (mathematical), and the other is integrative (based on experience and expertise rather than number-crunching).

A great deal of what is wrong with the extra-scientific debate is the overvaluing of frequentist statistics in domains where physical experience and understanding applies. Formulating this formally as a Bayesian question is more work than it's worth, I expect. But we still come away with impressions.

The statistical approach would be to go over the observational temperature records of the past century until about 1980, looking for a comparable anomaly. We'd have to set some parameters in advance: duration, physical scale, amplitude. Then we could evaluate. If no such events turned up, we would remain somewhat uncertain, the record being too short. If several did, we could easily argue that this event by itself is too "normal" to be "caused by" "global warming". On the other hand, we may well find that anything comparable occurred in the local winter; no summertime warm anomaly of this magnitude and persistence could be found.

Or we could argue that this is not an unusual "blocking" event; we have seen persistent meridional winds before. If you look at the pattern, you'll see that it doesn't actually stretch across the whole of Asia; there's a cool zone in the middle between the two hot zones. Now we are asking whether we haven't seen this particular flow pattern before. And I think that, in fact, will turn out to be correct.

Now we need to start talking about flow regimes and their connection to radiative forcing. And we're getting a little abstruse and into territory that people who don't know much about the atmosphere are lost. So they will try to drag us back to a proof of statistical significance. That's climate politics. Anything you say will be held against you. What we actually want to do is identify a mechanism whereby shifted forcing could result in this unprecedented jet stream regime. That's climate science; you're allowed to raise difficult questions posed by observation, and propose approaches to answering them. (I'll bet somebody will use a CGCM ("climate model") to investigate this problem before all is said and done. What do you think?)

But right now I feel like hazarding a guess. As far as I understand, nothing like this has happened before in Moscow.

I refer you to this paper on heat wave (and cold snap) mortality in Moscow by Revich and Shaposhnikov. Therein a heat wave is defined as a period where the daily average temperature exceeds a monthly average in the 97th percentile at least 5 times, and of those exceeding the 99th percentile at least 3 times.

They end up with a threshhold of "extremely hot" of a daily average of 22.7 C (72.9 F) in July, the hottest month. Even the coolest day in our five day forecast is several degrees in excess of this. Today's average temperature is is 29.8 C (85.5 F).

They mention in passing that the summers 2000-2005 were hotter than normal, at the 95 % level considering only July and August. They found an average of six days per month exceeding the threshold. "The heat wave of July 2001 was truly exceptional both in temperatures and in length." they say. "In July 2001, daily average temperatures exceeded 25 C for 9 consecutive days (the norm is only 3 days per year). Maximum daily temperatures on these days always exceeded 30C."

Let's compare with a list of new daily records (via a recent comment here by Alexander Ac):



Note in particular seven daily high temperatures in a row, all in excess of 33.2 C (91.8 F). And all time records (not just daily records) have been set twice since then. So it seems reasonable to suggest that the conditions we are seeing are bizarre. (If anyone knows more, please chime in.)

The formerly remarkable heat wave of 2001, then, is "the sort of thing we'll see more of" with global warming. But it may turn out reasonable, in the end, to say "the Russian heat wave of 2010 is the first disaster unequivocally attributable to anthropogenic climate change". (I also ventured something like this about the Australian fires last year.)

Remember this?

Barry Brook quotes an anonymous colleague, and agrees.
“Given that this was the hottest day on record on top of the driest start to a year on record on top of the longest driest drought on record on top of the hottest drought on record the implications are clear...

It is clear to me that climate change is now becoming such a strong contributor to these hitherto unimaginable events that the language starts to change from one of “climate change increased the chances of an event” to “without climate change this event could not have occured”.
It will take some time to settle out. But we've been so trained on the "loading the dice" thing that we may be excessively reticent.

This f***er is weird, and scary, and definitely gets filed in the "no time to relax" folder.

Update: While the weather is bizarre, the consequences (the fires and smoke) do indeed have a social component.

Yulia Latynina argues in The Moscow Times that forest management was gutted by Putin at the behest of the forest products industry. I am interested to see this story being picked up by rightwing web sites in the US. If this is the story it sure seems like deregulation and business-friendliness at work to me. It seems to refute the libertarian argument that private management is more responsible than public management.

Of course, we really need to compare to an alternative universe where the Russian bureaucracy remained in charge; it might well have been no better.
