The 10th anniversary of the still unpublished Watts et al. (2012) manuscript

Anthony Watts:
Something’s happened. From now until Sunday July 29th [2012], around Noon PST, WUWT will be suspending publishing. At that time, there will be a major announcement that I’m sure will attract a broad global interest due to its controversial and unprecedented nature.

Watts suspended his holiday plans, put his blog on hold over the weekend to work on something really important. With this announcement PR expert Watts created a nice buzz. Out came a deeply flawed manuscript on the influence of the direct surrounding of weather stations (micro-siting) on temperature trends.

Even before reading it the science internet was disappointed. David Appell responded: "Clunk. That, to me, seems to be the sound of the drama queen's preprint hitting the Internet.". William Connolley: "Watts disappoints ... its just a paper preprint. All over the world scientists produce draft papers and send them off for peer review. Only dramah queens pimp them up like this."

Roger Pielke Sr. burned another part of his scientific reputation build by his regional climate modelling work by writing a press release about his godson's manuscript: 

"This paper is a game changer ... this type of analysis should have been performed by Tom Karl and Tom Peterson at NCDC, Jim Hansen at GISS and Phil Jones at the University of East Anglia (and Richard Muller). However, they apparently liked their answers and did not want to test the robustness of their findings.. ... Anthony’s new results also undermine the latest claims by Richard Muller of BEST ... His latest BEST claims are, in my view, an embarrassment."

After all the obvious problems became clear, which somehow this eminent scientist could not find himself, he wrote a new blog post:

"To be very specific, I did not play a role in their data analysis. He sent me the near final version of the discussion paper and I recommended added text and references. I am not a co-author on their paper. I am now working with them to provide suggestions as to how to examine the TOB question regarding its effect on the difference in the trends found in Watts et al 2012."

The Watts et al. (2012) study is so fundamentally wrong in its basic design and execution that it is still not published now ten years later. While Watts naturally keeps on citing it to claim one cannot trust observed temperature trends. This fits to his new job at the Heartland Institute, a company so immoral that they still work for Big Tobacco. 

Below you can find some details on a recent study from Italy, which suggests that had Watts' study been done right, it would have found that micro-siting is a minor problem for climate trends.

The question of how micro-siting influences temperature observations is an interesting one. Expecting to see an influence on trends is another matter. I have no clue how that was supposed to work and Watts et al. (2012) also did not explain the extraordinary physics.

Even if such a thing existed Watts et al. (2012) could not have found convincing evidence on trends; the most fundamental problem of the study setup is that the study tries to analyse trends, which requires at least two points in time, but only had siting information for one point in time. Why this is a problem was explained well at the time by Pete:

Someone has a weather station in a parking lot. Noticing their error, they move the station to a field, creating a great big cooling-bias inhomogeneity. Watts comes along, and seeing the station correctly set up says: this station is sited correctly, and therefore the raw data will provide a reliable trend estimate.

To see an influence of micro-siting you need to something to compare with. You need to either have two points in time with information on micro-siting or two or more points spatially. Our Italian metrological (the science of measuring, not meteorologists, the science of the weather) colleagues of Meteomet did the latter.

Coppa et al. (2021) installed a weather station only 1-meter from a road and as comparison had a weather station 100 meters away from the road, perfectly sited in the middle of a grass field. More precisely they installed seven stations at 1, 5, 10, 20, 30, 50 and 100 m from the road and this is a 2-lane asphalt road, which is half a meter above the grass and leads to an airport in the surrounding of Turin, Italy.

Climatologically the most important plot in the paper is the one below. Let me walk you through it. On the y-axis is the temperature differences in Celsius compared to the seventh station, the one 100 meter from the road. The plot shows six box plot triplets; there are the six temperature differences. The three colors are for the daily maximum temperature (white), the daily average temperature (red) and the daily minimum temperature (blue). Careful, more common would be that the red color denotes the maximum temperature. The thick part of the box plots spans 50% of all observed temperature differences, the horizontal bar inside it the mean temperature difference.

So the temperature difference of the station closest to the road to the well-sited station is ΔT₁, the triplet at the left. The maximum temperature close to the road is 0.12 °C warmer, the average temperature is about 0.2 °C warmer and the minimum temperature is 0.3°C warmer. With increasing distance from the road, these small effects gradually become smaller, which gives confidence that these differences, while small, are real. This is somewhat less true for the maximum temperature, which behaves more erratically.

This metrological study is important for climatology, even if it basically found a null effect. Understanding uncertainties in measurements helps us focus on the real problems. Unfortunately such studies are not cited much and unfortunately too often the importance of science is judged by the number of citations. This study clearly illustrates why this is a bad way to micro-manage science.

What does this mean for observed global warming trends? To make a worst case estimate one could assume that all stations were perfectly sited on lush grasslands in the past and are now close to a road in a subtropical climate with harsh sun light to get a trend error of 0.2 °C in the mean temperature of land stations, which represent a third of the Earth's surface. So even with such unrealistic assumptions this would change the global temperature trend much less than 10%.

The opposite scenario might be more realistic. Climate stations often started close to buildings as the then expensive scientific instruments had to be read by observers. Nowadays it is easy to build an automatic climate station with autonomous power and radio communication far from buildings.

The upside of this being the 10th anniversary is that people could check the micro-siting of the stations again and have two time points. It would likely give a null result, but that is valid.

4th anniversary of Variable Variability


The previous birthdays I have simply forgotten, my apologies, but today is the 4th anniversary of Variable Variability.

More than usual birthdays, the day is a bit arbitrary. Many years I already wrote the occasional essay for my homepage. Ideas that I wanted to share, but were not big enough for an article or thoughts that I was afraid I would forget again with my terrible memory.

The first post of Variable Variability on the 30th of April 2011 was thus a republication of an essay from 2004 on the fractal nature of clouds and the limits of the fractal approximation.

The first two posts specially written for Variable Variability are: Is obesity bias evolutionary? and Good ideas, motivation and economics, both on the 28th of May 2011 somehow. Must have been a writing-fever day.

They are still good posts, but not much read because of the time they were published. To reduce your weight it may help to consciously eat less and move more, but that is an empirical question, it is not as obvious as many claim. Science is a creative profession and knowing where good ideas come from can thus be helpful. The second skill would be a good intuition, which of these problems to tackle. You also need technical skills, but they are overrated.

Another contender for the beginning of this blog would be January 2012, when I posted a press release on the famous homogenization validation study of the COST Action HOME. From a meeting several years before, I vaguely knew that Roger Pielke Sr. was interested in homogenization. Thus I asked him if he was interested in a repost. Roger referred me to someone called Anthony Watts of Watts Up With That. Coming from a good source, Watts asked me whether he could repost, maybe he noticed that I was not too enthusiastic (I had read some WUWT posts by that time) or maybe he read the post (and did not like the message that homogenization methods improve temperature trend estimates) because in the end he did not post my press release.

To promote the press release I started to look a bit more at other blogs and comment there. Now I see this as part of blogging, thus you could see this as the start of blogging.

Mitigation sceptics seem to have a tendency to think that scientific articles are written for the purpose of pissing them off. But they are not that important. Most scientists hardly know they exist. I did know that there was some trouble on the other side of the Atlantic in the USA, that a larger group there was sceptical about climate change. Being sceptical is sympathetic and there are so many real uncertainties. So why not? I was completely unprepared for the industrial production of deceit and misinformation and the rock bottom quality of the nonsense these people made up. I still wonder why mitigation sceptics do not orient themselves by the real uncertainties and problems; they are spelled out in detail in every IPCC report. It sometimes looks like winning a debate is less important to the most vocal mitigation sceptics than angering greenies, which is best done by stubbornly repeating the most stupid arguments you have. (In the light of the discussion we are just having at ATTP, let me add that I this is not an argument, I do not think this paragraph will convince anyone of climate change, I am just describing how I personally see the situation.)

Like the blogger of And Then There's Physics, I naively thought that it may be helpful to explain the mistakes in the posts of WUWT. Now keeping more of an eye on other blogs, I noticed a WUWT post about an erroneous conference abstract by Koutsoyiannis, which was called a "new peer reviewed paper". I wrote: "As a goal-oriented guy, Anthony Watts found the two most erroneous statements". That was the first time I got some readers and at least Watts admitted that there was no peer review. The other errors remained.

Earlier this year I wrote a short update:
Now two and a half year later, there is still no new activity on this [Koutsoyiannis] study. I guess that that means that Koutsoyiannis admits his conference abstract did not show what the State of the Climate and WUWT wanted you to believe. Together with all the other WUWT fails, it is clear that someone interested in climate change should never get his information from WUWT.
But well, who is listening to me, I do not have the right party book.

A little later Anthony Watts put WUWT on hold for the weekend because he was working on something big. He had written a manuscript and a press release and asked for blog reviews. Thus I wrote a blog review about this still unpublished manuscript. This was the first time this blog got a decent number of comments and the time people informed each other in comments elsewhere that there was this new blog on the block. That was fun.

I have somewhat given up on debunking misinformation and aim to write more about what is really important. Sometimes the misinformation is a nice hook to get people interested. I had wanted to announce the birth of the new Task Team on Homogenization (TT-HOM) anyway. By connecting this to the review of the UK Policy Foundation with silly loaded questions, more people now know about TT-HOM than otherwise; normally setting up a a new Task Team would have been a boring bureaucratic act not much people would be interested in.

Debunking does not seem to have much impact, even in cases of clear misquotations and when Watts deceives his readers about his number of readers, there is no bulge. The number of WUWT readers is a small matter, but it does not require any science skills to check, everyone can see this was deception. However, no one complained about being lied to.

America's problems with mitigation sceptics are not because of the science, mitigation sceptics seem to make this claim to make adult political debate about (free market) solutions impossible. By not complaining about deception they make clear that their issue is not the science. Their response to a new scientific paper is almost completely determined by the question: can it be spun into a case against mitigation? If they were interested in science, their response would be determined by the quality of the study. America's problems with mitigation sceptics can thus also not be solved by science or science communication. The American society will have to find a political solution for their toxic political atmosphere. Maybe that simply starts by talking to your neighbour, even if he has the wrong bumper sticker. Go on the street and make it clear to everyone this is important and something to think more about and make it clear to politicians that it is costly to peddle nonsense.

Wishes

Blogging has been a lot of fun. I like writing, playing with ideas and debating.

The first two posts got 50 to 100 pageviews up to now. They were purely written for fun.

If you write a scientific article you can also be happy to get a 100 readers. But if it inspires someone else to continue the thought, to build on it, it is worth it.

Compared to the number of readers a scientist is used to, this blog is a huge megaphone. Thank you all for reading, your interest is very rewarding and nowadays another reason to write posts. With that megaphone also comes responsibility. I guess that mitigation sceptics will not like much of what I write, but when colleagues do not like something I hope for their honest feedback. That would be valuable and is much appreciated.

Blogging has given me a broader perspective on climatology and science in general. Where else would I have heard of the beautiful ideas of John Zyman on the social dimension of science? (Thanks Mark!)

A birthday is a good day to wish something. Do you have anything you would like me to write about? I will not promise anything, I still have about 100 drafts in the queue, but welcome new ideas. I am always surprised how much people read my posts about how science works and the intricacies of the scientific culture. It is my daily life, almost like writing about washing the dishes. It is easy for me to have a blind spot there, thus if you have any questions on science, just shoot.

Please do not wish a post why homogenization increased the trend for some station in Kyrgyzstan. Not on a birthday.

The quality assurance system of WUWT

My immature and neurotic fixation on WUWT

More neutral titles for this post could have been: "why do I blog about pseudosceptics?" or "how to play climateball(TM) for scientists".

Last week I wrote about the unchristian, indecent, ugly language at WUWT, in my post: The conservative family values of Christian man Anthony Watts. Just a sample: Pathetic whining, creature, sub-human, odious toads, evil, Hitler, Stalin and diseased narcissism (archive).

I just noticed that I had missed an insult by Anthony Watts himself, in his response to my request to remove a comment with the usual pun on my last name.
Looking at how often your cite WUWT in negative connotations, I’d say you have a fixation.
To fully appreciate the insult, you need to clicking on the link to Wikipedia. (Let's ignore the irony of Watts linking to Wikipedia in a post about how unreliable Wikipedia is and how the evil William M. Connolley single handedly turned Wikipedia into an alarmist CAWG propaganda tool. In other words, how Connolley as one of the editors and backed by the scientific literature kept their nonsense to a minimum.) Wikipedia writes about fixation (psychology) (archive):
Fixation is a concept originated by Sigmund Freud (1905) to denote the persistence of anachronistic sexual traits. ... More generally, it is the state in which an individual becomes obsessed with an attachment to another person, being, or object (in human psychology): "A strong attachment to a person or thing, especially such an attachment formed in childhood or infancy and manifested in immature or neurotic behavior that persists throughout life". ... Fixation to intangibles (i.e., ideas, ideologies, etc.) can also occur.
While minor compared to the language directed at Connolley and Mann, that is not a very nice thing to say. I would see it as an indication for a rather modest willingness to engage in a constructive dialogue to improve mutual understanding.

I guess a fitting reply would be: projection. Also part of Wikipedia's coverage of psychology.
Psychological projection is the act or technique of defending oneself against unpleasant impulses by denying their existence in oneself, while attributing them to others. ... Although rooted in early developmental stages, and classed by George Eman Vaillant as an immature defence, the projection of one's negative qualities onto others on a small scale is nevertheless a common process in everyday life.
Climateball is hard to sustain if you are not having fun. Are we even now? #kindergarten

Had Mr. Watt chosen a nicer term, he would have been partially right. Let me try to explain in this post why I blog and comment on pseudo-sceptics and especially on WUWT. This post will finish with some ideas on how to do so effectively.

I like using the term WUWT & Co. for blogs that spread misinformation about climate science. It is a neutral and clear alternative to "denier blogs", which the speudo-skeptics claim points to holocaust deniers. It does not, but one should not give them too much opportunity to change the topic.

A reason to find WUWT somewhat interesting is that the pet topic of Mr. Watts is the quality of weather stations. That is how I got introduced to the man. After writing a paper on the homogenization methods to remove non-climatic changes from historical instrumental data, I wrote a blog post about this. Knowing that Roger Pielke Sr. was also interested in that topic, I asked if Pielke was willing to repost it. He referred me to Watts, who asked me for permission to repost it. He probably thought I was okay, because of Pielke. After reading that homogenization improves temperature trend estimates, he never published it. You have to set priorities.

The main reason for my interest, however, is probably my personality. I like to understand how things work. I like civilised debate. I like reason. Hearing or inventing a new strong argument is a joy, similar to the joy of listening or making music. When I hear a claim, no matter how much I like the person or claim, my brain automatically starts producing counter arguments. This is a very effective way to annoy people, my apologies to all my friends for that.

That is who I am, that is why I became a scientist. I also believe that reason, civilised debate and the power of arguments are what have given us the rule of law, democracy, human right and prosperity. They are the foundation of our open societies and they are what WUWT and Co. are destroying in their political battle against science.

Knowing a little about climate and knowing how science works, it is obvious to me how wrong most of the WUWT posts are. It would be hard for me not to refute this nonsense. As WUWT is the biggest blog of this community and can be seen as its mainstream, it seems to make sense to give it more attention as even more extremist blogs that not even pseudo-sceptics take seriously.

Creationism is even more irrational. The evidence for evolution is even stronger as for climate change, by orders of magnitude stronger. However, that is a local problem the Americans have to deal with. The misinformation of WUWT and Co. affects all. Climate change is certainly not the only important global problem, but a solvable one.

If people would decide that it is better to suffer the consequences as to solve the problem, so be it, that is democracy or as Jac. commented at AndThenTheresPhysics:
In a democracy, you have to respect if the people’s consent is that they will accept climate change with all its consequences to happen; but at least let scientists make sure it is an ‘informed consent’ then.
That quote is the end of an interesting discussion at AndThenTheresPhysics. A discussion about the value of refuting climate "sceptics" and how scientists can contribute. As many people do not read comments, I would like to summarise this discussion below.

I have to admit to like reading comments (and call-in radio), especially at AndThenTheresPhysics. Most comments are not informative, but you have the chance of reading or hearing something you might otherwise not hear in the mainstream media.

Others disagree and like comments less.

Click on the time stamp to see the comments on it.

The not yet very interesting opening gambit at AndThenTheresPhysics (ATTP) was by Mike Fayette.
So why not find common ground with the skeptics and actually try to get something useful done? .. Mock the folks that exaggerate the threat the same way you mock the folks who deny basic physics.
The simple answer to the first part is: you can try to find common ground about political problems. Climate "sceptics" hinder this political discussion by refusing to talk about politics and claim problems with solid science. Unfortunately, you cannot negotiate with nature. Reality simply is.

The answer to the second part is that it is rare that people who worry about climate change make claims that are clearly untenable. Reality is sufficiently scary and is for them more then enough reason to act. Furthermore, climate change is a wicked problem with a lot of uncertainty and especially on the warm side it is hard to exclude much. Still, if people get too warm and fuzzy about climate change, I naturally do correct them.

My favorite future blogger, Mark Ryan, replies:
Mike Fayette’s comments, and his experience, are very interesting, [VV: If someone at a scientific conference starts a reply this friendly, expect a nasty comment or question.] and make me think about the problem of how scientific communities relate to evidence, compared with how the public –and particularly the political communities in the public- relate to it.

There is a lot of confusion about the fact that knowledge is fundamentally a social property –no individual can claim decisive knowledge across a domain (actually, some individuals obviously do, but they’re invariably wrong). What happens instead is that individuals [scientists] build on what they understand to be established knowledge, do their work, and add it to the constellation of previous and contemporary contributions.

Some elements within the knowledge constellation are much better established than others, and are therefore more likely to be true –with the well-worn caveat that no question is ever 100% closed. But this caveat is actually much more trivial than those who misunderstand it would have us believe; this point was never made better than in this short essay by Isaac Asimov. This is the best response I can think of to Mike’s earlier remark about competing theories in science.

There must be a hierarchy of knowledge for scientific knowledge to be possible. Core ideas support the contingent or peripheral ideas, otherwise every researcher’s work would arbitrarily re-establish first principles. ... Almost all research deals with anomalies or minor controversies, but based on established foundations; if someone wants to remake the foundations, they quite rightly find it hard going. ...

We have had over four decades now of a constant conflation of politics and science, a response to the culture of scientistic authority promoted in mid 20th century, and the new kinds of health and environmental risks that modern life has created. The net result is that complex and specialised knowledge is counterposed to commonsense and intuitive, easy to relate to, (but incorrect) alternatives. This is the “better story” that Mike mentioned, and large percentages of the public just buy into this without a second thought, because they are now conditioned to look straight past specialist scientific knowledge to project political motives onto the people making it. For people who buy into this politicisation of science, there is no need to educate themselves to understand the complex theories and jargon of the scientists, because in any case, they imagine scientists use facts the way we all see lawyers use facts in various media. It does not occur to them that the simple explanation has already been considered and improved on by the people who study the topic. ...
A clear example of such a simple explanation is the meme going round that CO2 is heavier than air, will thus stay close to the ground and cannot act like a greenhouse gas. (This ignores turbulent mixing.) Do people really think that no scientist in all these decades has ever tried to measure up to which height CO2 is a well mixed gas? It is fine to ask such a question. It is insane to immediately claim to have refuted the greenhouse effect.

Mark Ryan continues to explain that blogging about science makes sense:
ATTP, you said in your post that you were going through a phase of wondering what the whole point is.

It is a few years back now, but I started reading blogs like this one as a skeptic. My training is in politics and the philosophy of science, which at least gave me some basis for spotting patterns in the literature I was reading. My interest in climate came from my interest in the philosophy of statistics, but I had read social theorists like Thomas Kuhn, Harry Collins and Michel Foucault, and was predisposed to a very political take on the production of scientific knowledge.

Not having the appropriate scientific background, I needed to visit sites like this – at the time it was Tamino, Skeptical Science, Real Climate[,] etc, just so I could understand what I was looking at when I tackled even things like IPCC papers. Eventually, the most striking pattern I found in the so-called ‘mainstream’ climate literature was a constellation of arguments converging towards consilience [consilience refers to the principle that evidence from independent, unrelated sources can "converge" to strong conclusions], and a rigorous commitment to explaining the science. I didn’t find sites like Joe Romm’s very helpful, by contrast.

On the so-called “skeptical” sites, and in the small amount of scholarly literature, the pattern is negative -mutually contradictory arguments. This body of literature was not converging to an alternative, but was fixated on driving wedges into any cracks of uncertainty they could find. It was the comparative ‘shapes’ of the two different bodies of argument that convinced me.

I want to say I think what you do is tremendously valuable; it is clear, articulate, and sets a tone that encourages skeptical people, like the one I used to be, to stay with you. In this intensely polarised environment, that is a delicate act to pull off, but if I was running a blog, you would be one of my models. It is one of the unfortunate things about blogging, that you send your missives out into the void and never quite know whether you’re making any difference -it’s a kind of alienated form of social being, in a way. But you create a rare environment here, so well done.
Jac. had a similar experience as Mark Ryan and added:
... I am not a scientist. I am working in the legal/judicial system. The number of climate change cases that are brought to the courts is growing, and so is the body of literature about climate change liability that I am especially interested in. I think I am quite well informed on the legal liability aspects of climate change and the potential role of the judiciary. I started reading off and on some blogs about climate change some months ago, because I wanted to try to understand some of the science as well, and I also wanted to learn and understand about the way scientists and skeptics interact and discuss about their arguments and what these arguments are.

So my background and reason to start reading this blog seems to be somewhat similar to Mark Ryan. I completely agree with what he wrote (23/5, 1.30 pm) about the ‘shape of the two bodies of arguments’. I made the same observations, and arrived at the same conclusion.

I also noticed that generally speaking there is a difference in ‘tone’ and ‘style’ in the way the scientists argue and the way ‘skeptics’ argue.

Typically, the question of the scientist is one out of curiosity, whereas the questions of the skeptic are typically more like an aggressive cross-examination. Also typically the skeptic is not satisfied with the answers he gets; there is always another question following, never mind if it is coming from quite a different perspective, or he just changes the subject or disappears. Therefore, in my perception the typical skeptic is not interested in finding common ground with the scientist; he is on a ‘fishing expedition’ to see if there are any contrarian arguments that cannot easily be discarded by scientists, so he can claim that the science is far from settled and too uncertain for political decisions.

So my conclusion is that the skeptics in the blogosphere are not genuinely interested in (the advancement of) climate science.

If that analysis is correct, scientists have little if anything to win in engaging in discussions with skeptics on scientific issues because the skeptic has nothing to offer there and has a different agenda altogether. I am not at all surprised then that for scientists, discussions with skeptics can be irritating and tiresome. I assume that is what ATTP meant when he started this post.

For me these discussions are not pointless. For me, seeing how the arguments flow was helpful in understanding the climate debate. Like Tucholsky said: the understanding that the people have is usually wrong, but in their sensing the people are usually right. This blog has been guiding my ‘sensing’ of the climate debate and who is right probably just as much as it has been guiding my understanding of the arguments. ...

I wonder what it would be like if scientists would not engage in discussions with skeptics with the intention of convincing them – they won’t allow you to – but with the intention to demonstrate to other lurking readers (like me) that science has better (and more polite) answers and deeper understanding to offer than the skeptics have. It might turn out to be a whole other kind of ballgame, one that is far less frustrating for scientists.

And if you don’t feel like playing anymore, I think it would be perfectly OK to say ‘we have tried to explain you the science more than once, but either you seem not able to understand the science which is regrettable, or you just do not want to understand which is fine, but either way and with all due respect you have offered nothing to this discussion that has any merits and you and your repetitive comments are becoming a bit of a boring noise, so thank you for participating, but we will block you from this post / this blog.’ I think scientists could be a little more assertive about sticking to the rules of their discussions.
Our climate philosopher, Willard, got scared:
No more ClimateBall ™ ?
http://www.khaaan.com/ [Warning sound]
Jac. could reassure him:
Still Climate Ball I suppose, but how scientists want to play it. If scientists start perceiving (and thus expecting) that the game is not about trying to find common scientific ground with the skeptics or about advancement of science, but about proving how wrong/mistaken the skeptics are (while still maintaining the cool, rational, unbiased and open-minded, fact-based balanced way of truly scientific reasoning that, in my view, really is the stronghold of scientists that earns them credibility), scientists might find it less frustrating to be playing the game. In this other version of Climate Ball moving the goalposts is considered as acknowledging you have lost the previous argument. Don’t complain about moving the goalposts, but instead explicitly claim it as victory and as soliciting for another beating on another subject.

My selfish reason for suggesting this is that I would not want the scientists getting so frustrated that they are pulling out of the debate.
AndThenTheresPhysics regular BBD followed the same route and wrote previously:
FoxGoose, it’s an open secret that I used to be a fake sceptic. At one time, it was something of a USP [Unique Selling Point], even. Quote mining my past is an old, tired tactic. It also reveals something rather unpleasant about those doing it.

But to answer the question:

- I’ve learned more than you in the last three years.

- I’ve demonstrated that I am intellectually honest enough to overcome my denial.

- I’ve got the balls to keep the same screen name and own every statement I’ve ever made in public using it.

- Once I discover that I have been lied to and manipulated, I never forgive and I never forget.
Rachel naturally asked: "Wow, BBD. What made you change your mind?"
I discovered that I was being lied to. This simply by comparing the “sceptic” narrative with the standard version. Unlike my fellow “sceptics” I was still just barely sceptical enough (though sunk in denial) to check both versions. Once I realised what was going on, that was the end of BBD the lukewarmer (NB: I was never so far gone as to deny the basic physics, only to pretend that S [the climate sensitivity] was very low). All horribly embarrassing now, of course, but you live and learn. Or at least, some of us do. ...

Always check. Fail to do this in business and you will end up bankrupt and in the courts. I failed to check, at least initially, and made a colossal prat out of myself. Oh, and never underestimate the power of denial (aka ‘wishful thinking’). It’s brought down better people than me. ...

There wasn’t a single, defining eureka moment, just a growing sense of unease because nothing seemed to add up. ... Once I eventually started to compare WUWT [Watts Up With That] with RC [RealClimate] and SkS [Skeptical Science], that was it, really.
Thus maybe the information deficit model is not that bad. At least when people have to time to gather all information, hear all sides and think it over. Thinking deficit model might be a better name. How do we get people to start thinking? One way would be to reduce the vitriol in posts about science, this reduces critical thinking and strengthens tribal thinking. (Hard to do, the dramatic opening helped to get you to read until here.)

It also points to the importance of trust. Being lied to is not nice. In that respect I would not expect BBD to ever go back to the climate "sceptics". If BBD detects an inconsistency, I would expect that he would simply point it out to scientists. The way scientists do. If the evidence changes, you will hear it first from scientists.

Building up trust again will be hard for the pseudo-sceptics after having displayed how untrustworthy they are. But it would help if they would stop their disinformation campaign against science, stop repeating their completely idiotic talking points, and would start to make scientifically valid points about real uncertainties and weaknesses. They would be welcomed back home. Unfortunately, that is somehow a huge if and I do not expect this to ever happen, just to see the group get smaller and smaller, being laughed at by their neighbours and die out.

Steve Bloom wondered:
Jac, as I’m sure you know, most scientists, even climate scientists, choose not to play [Climateball] at all. But is it helpful to imagine the response to this blog (and the climate science blogosphere generally) of such a non-player who is considering starting to play? Is the lesson that other forms of engagement and outreach (e.g. reaching out to their local media and giving community talks) are a better use of their time? Or maybe it’s most effective to instead focus their research efforts onto things that will inform a better policy direction?
Many scientists are introverted or otherwise not interested in a public debate. That is fine. As a community we should be present, but people should do what they do best. Most "challenges" by pseudo-sceptics are so basic and repetitive that many lay people following the climate "debate" may well be better suited to reply.

Outreach will not help you avoiding the pseudo-sceptics. They will be the ones motivated to ask the questions. Expect some creative and weird ones. But eye to eye even pseudo-sceptics know how to behave. Youtube suggests that the main exception to that rule is Lord Monckton. (Highly recommended funny video about the comedian behind Monckton).

To close, Willard summarised the climate "debate" as:
ClimateBall™ can be fun! Stripped down to its bare essentials, ClimateBall ™ is just a conversation disguised as a scientific discussion.
More seriously, Jac. closed with the main purpose of the "debate":
In a democracy, you have to respect if the people’s consent is that they will accept climate change with all its consequences to happen; but at least let scientists make sure it is an ‘informed consent’ then.
What did I learn about the climate "debate" from the above comments?

1. Do not expect to be able to convince the people that have being a climate sceptics as their identity. Explain the science and explain why the climate "sceptics" are wrong for the lurkers. Explain why science is fun and why it produces reliable knowledge. Show you are open and interested in a better understanding.

2. Stay on topic to be able to go in depth like scientists would if they have a dispute. Pseudo-sceptics like to change topics before acknowledging that they were wrong on their first one. Make this strategy clear to the lurkers and explain that this suggests that the pseudo-sceptics are not really interested in understanding the problem. If necessary "answer" new topics with links (e.g. to the Skeptical Science list of Global Warming & Climate Change Myths).

3. Be friendly to people you do not know and might be honestly interested in the answer. There is no need to accept any kind of abuse, but try to make sure that there is a clear difference in tone between science and non-science.

4. Search for the name of your discussion partner and the topic. Very often he has discussed the topic before somewhere else and already knows all the answers. In this case, point out to the lurkers that your discussion partner is not interested in the answer, but just wants to create doubt.

5. Be fairly strict with moderation on your own blog, if you have one. The ugly language at WUWT we started this post with is great for stroking tribal feeling and very effective in reducing people's ability to think rationally. Not something you would like to see at a science blog. Personally, I also remove a large part of the comments without arguments, they waste the time of the reader looking for a real discussion. If you do this, you will only have to remove few comments, because people will adjust their tone.

6. Another function of the ugly language may be to discourage scientists from taking part. Try to ignore the misconduct and not to take it personally. These people do not know you and are only demonstrating their own problems. This is clearly illustrated by the hilarious puns on my last name. If those people would know me only a little bit, they would at least write something about homogenization or about my fixation with WUWT.

Try to have fun playing climateball and keep your eye on the WUWT ball.

[UPDATE. Maybe this and the previous post worked. Anthony Watts created an Open thread and asked what could we do better? He gives some suggestions himself.
3. I’d like less name calling. The temptation is great, and I myself sometimes fall victim to that temptation. I’ll do better to lead by example in any comments I make.
4. I’d like to see less trolling and more constructive commentary. One way to achieve that is to pay attention.
Let's see, how this works out. I am somewhat sceptical because they need the tribal atmosphere to suppress critical thinking. ]

[UPDATE: Just found an old post on Skeptical Science, Understanding climate denial, that mentions three more people that changed their mind based on the evidence, D.R. Tucker, Craig Good & Nathan McKaskle. It is not impossible, but probably still rare. Ironically Nathan McKaskle used to be a blogger, but gave up not knowing whether he had changed a single mind. That is a pity, changing people's minds does not happen immediately after reading an article, it takes time, if only to be able to say that one has always held the new position.]

[UPDATE 2016. Just found two more people convinced by science: Windchasers and Tadaaa. It does happen.]

Every time I examined a denialist argument, a little research quickly convinced me that they were wrong; invariably their references were unreliable and their arguments incoherent.

The conservative family values of Christian man Anthony Watts

[UPDATE II: Anthony Watts responds. With intimidation.]

[UPDATE: WUWT Moderator dbstealey feels that William M. Connolley is evil; see below]

Anthony Watts has a reposted an ugly article by Pointman about William M. Connolley, in which I have a cameo appearance as collateral damage. The comments below the post are below any level. Williams name inspires these good Christians to toilet puns. My last name reminds these Republicans of the last time they had anal sex. I guess it would be of no use to explain these man of the world that the Dutch name Venema does not rhyme to the English word enema.

Maybe Anthony Watts did not notice these comments, he is so busy searching for the truth after all. Thus I asked him:
Dear Anthony, I am saddened that you would repost something like this. I had expected better of you. While I understand it would be pointless to ask Pointman to do so, could you at least remove the pun on my name by ATheoK and the various hilarious puns on William Connolley's name, please?
This comment was not published, but replaced by [noted]. The comment by ATheoK was not changed. And I even asked politely, last time the enema appeared on WUWT, Anthony Watts was only willing to remove it if I repeated the request with the magic word please.

My next comment:
Victor Venema says: [noted]

Dear Anthony Watts, it is regretful that you approve of the horrible language used in these comments. This ugliness is not something I had expected to see at WUWT, if only on opportunistic grounds. Don't you want WUWT to be a broadly read somewhat respectable mainstream anti-CAGW blog? The comments on this post do not sound like conservative or Christian family values to me, but more like atheist übermensch extremist thinking.

If you have to resort to this kind of language, you have lost the rational debate. Kudos for making this official.

While we now know that you condone abusive language, I am wondering if you also officially support misinformation. You know that this statement by NikFromNYC is wrong: "Here is the hockey stick you [Connolley] helped create, the WUWT site rating that just tripled in 2013: http://www.alexa.com/siteinfo/wattsupwiththat.com"

Surely, having "the world's most viewed site on global warming and climate change", the number of readers is important to you and you know your blog statistics. Any other blogger knows, surely you do. You know this is wrong, you need no scientific knowledge or skills to see this. You also publish the Wordpress summary results at the end of the year and everyone else knows it is wrong. Don't you think that the right thing to do would be to correct this misinformation? What would Jesus do?
In the hope of getting this one published, I had not added the link with the evidence that Watts has no respect for reality whatever the topic.

Fortunately not all conservative Christians are like Watts and his ilk. Maybe it helped that I had just had a long detailed and mainly pleasant discussion with Evan Jones on the Watts et al. (2012) manuscript. If people want to honestly discuss science, I am happy to talk to them if I have some expertise. Jones writes:
Over the last year-plus, I have had oddly reasonable exchanges with both Connolley and Victor Venema concerning the surfacestations paper. We explored their three main objections and have addressed them. That was actually quite valuable, as it turns out.

I do understand that they are controversial figures, and many have crossed swords with them, but I have made out okay. They found out we are for real — which they needed to know. I found out what their criticisms are and where how they will be arguing against the paper, down the road — which I needed to know.

REPLY: he seems to have a different persona when not in public view. In my case here and at his own blog, he wears his contempt on his sleeve – Anthony
I will be so modest and assume that Watts is speaking about Connolley. That does not resolve the difficulty of understanding how commenting at WUWT and writing on your blog would be outside of the public view. But then, that doesn't really matter, I have given up trying to understand these fake sceptics, the only reason to debate them is to show the lurkers the way back to reality.

The more important question is why the American evangelical Christians are sacrificing their place next to Jesus with their support of such a dishonest and uncivilised political movement. Christians in the rest of the world seem to read another bible and would never condone such unchristian behaviour. In the USA, the people of the Evangelical Environmental Network (EEN) have already realised this.

While I understand that conservatives do not like some of the proposals for policies to combat climate change put forward by progressives and greens, I am disappointed by them tolerating this kind of language in their ranks. Weren't the conservatives once the people that wanted to conserve civilised manners, that claimed to have the moral and Christian values on their side? What happened to these conservatives? How could the rude behaviour of Anthony Watts and Rush Limbaugh become the conservative life style?

If you would explain a Martian the original conservative ideology, these Martians would expect conservatives to respond to climate change the way Newt Gingrich proposed, instead of betraying their own values in comments at WUWT and Co.

[UPDATE: It has gotten even worse, after all the vitriol there were two sane comments.
None of which excuses the reference to him [@wmconnolley] in the original article as “creature” or the comment reference “sub-human”.
I agree with The Other Phil. It doesn’t help to simply throw names at anyone,especially not terms with such an unpleasant history
So much humanity broke WUWT "moderator" dbstealey's back. He quoted from a piece about Elliot Rodger, Osama bin Laden, Anders Behring Breivik and Christopher Dorner:
Evil is not limited to the occasional spree killer. In the last century Hitler and Stalin oversaw cults of personality built on this same model under which millions died. Stalin’s Communism and Hitler’s National Socialism were messy and contradictory ideologies. They ultimately existed so that one man could exercise his power fantasies and destroy as much of the world as he could. And here in our own country, there is an ideology that is obsessed with controlling and shaping all of human behavior. We call that ideology by many names such as liberalism or progressivism, but it’s more accurately a diseased narcissism whose followers strive to stamp out anyone who doesn’t think like them, and to control the lives of everyone else.
And commented that quote with:
It’s from another blog, but guess who it applies to here [my bold].

That also applies to Michael Mann. Anyone reading his tweets and other comments knows what a warped person he is. Personally, I could understand pretending to have won the Nobel Prize. Lots of insecure folks self-aggrandize with fictitious accomplishments. But Mann constantly flings out insults at anyone and everyone who doesn’t toe his line, and he cowers from any fair debate [I suspect that connolley would tuck tail and run from any fair, moderated debate, too, since the science flatly contradicts his bogus narrative].

We are dealing with people who would be rejected by any normal society. But this is life in the new millennium. We just have to keep plugging away. And so far, it’s working.
On other blogs the moderators have the responsibility to keep the discussion somewhat civilised. Anthony Watts' guard dog, sock puppeteer and favoured mod, dbstealey aka Smokey aka dbs aka D Boehm aka who knows what else sees this differently.

No idea why Michael Mann suddenly makes an appearance.

Creature, sub-human, "the WC needed cleaning", "WC flushed", odious toads, evil, Hitler, Stalin and diseased narcissism. Those are the words of extremists, I would not want to get my science information from.

The idea that William M. Connolley would run away from any debate is almost funny. Given that he was commenting below this ugly post, which is an unfair and badly moderated debate, especially when dbstealey comments using one of his many sock-puppets and simultaneously moderates his opponents. Previously Connolley has offered to debate Lord Monckton, but the Lord did not take up the offer.

The often used term narcissistic to describe Connolley is probably the most ironic part. It is pure projection: it are the extremists at WUWT that think that William M. Connolley single handedly kept Wikipedia's climate articles clean of their nonsense. They are the ones that do not recognise the swarm intelligence of Wikipedia and how Connolley could never have kept Wikipedia clean without the other Wikipedia editors and the scientific literature.]


[UPDATE II Now also Anthony Watts chipped in. His response below my second comment, the published one, is rather long and content free. You can read it in this archive if you want to check my paraphrases.

I found it because William M. Connolley tweeted: AW invents new version of Godwin: "Oh puhleeze, invoke Jesus? Nope that’s when YOU lose".

The key sentence may be: "I know your university stoked ego can’t assimilate criticism from us mere peasants, so I don’t bother."

It would be nice if he would not bother and would stop the misinformation campaign, he calls "criticism" and I call WUWT.

The term "university stoked ego" probably tells more about Watt's inferiority complex than about me. My last name, which the ugly crowd at WUWT likes to make fun of, actually means peat bog worker in Dutch. I am the first in my family to obtain a PhD. Coming from a relatively poor background I am extremely thankful for the enormous support and trust society has given me for my studies and now to be allowed to do the job I love.

A job I love because of the culture of curiosity, reason, civility and truth. The anti-thesis of WUWT and Co. If Watts feels like a peasant, he might think about why scholars, scientists and cultured people no longer feel welcome in the Republican party where only two generations ago they could still be proud to be a Republican. These groups have the same range of political preferences as everyone else. Thus my guess would be that they are disgusted by the anti-intellectual and coarse political culture and by people putting ideology above values. WUWT is a mere symptom of this larger problem.

Watts may also feel inferior because people so often find that the posts at WUWT are completely wrong. This is documented daily on HotWhopper. However, Watts should not take this personally. If I had to publish five posts a day, my quality would also go down. Especially, if those posts would have to follow an ideological story line and I could thus not orient myself by the scientific literature. Given those difficult circumstances, Watts is doing a great job and I have often praised him as a great PR expert.

The next complaint is that I would "whip up comments here [at WUWT] then go write a post [at Variable Variability] about how terrible we are here [at WUWT]." I don't know. I thought this was called decency. To first alert Anthony Watts that there is a problem and to give him the possibility to correct it. I find that more decent as immediately writing a post about an over-the-top comment, the way Anthony Watts did about a comment someone made at AndThenTheresPhysics that was removed when people complained. But maybe those are just my exotic moral values.

Is it necessary to state that the comments below that WUWT post on AndThenTheresPhysics were similarly hateful. But were not removed?

Next Anthony Watts sends a mixed message. Climate "sceptics" often complain that scientists are not willing to debate them, like dbstealey above, but when scientists show up they are bullied.

Watts published my comment email address; the good Christian regularly intimidates people by publishing private information when he feels cornered. He "calls me out" for using my university email privately and threatens to write a blog post about Victor Venema and the University of Bonn to flesh this out. Nice chap, isn't he? That will stimulate civilised debate.

(Dear readers, do not worry, private use of the internet is allowed in Bonn and Germany has freedom of research in its constitution, thus I do not have to fear harassment by the fake sceptics. I am happy to life in a country where scientists cannot be bullied by political pressure groups that do not like the inconvenient results.) ]

Why doesn't Big Oil fund alternative climate research?

A short post. Asking the question is answering the question.

Jo Nova, an Australian climate ostrich, is begging for money to keep blogging. Anthony Watts helped her with an appeal to his readers. Below his post "ClimateReason" complains:
"We are woefully underfunded and under resourced. Every sceptic I know of has to fund their own projects and have jobs unrelated to their interest in climate.

It takes me a year to research my large articles. Who funds me? No-one. Can I afford the time and money? No. Could I do more if Big Oil funded me? Of course. But they don’t, because money from this source for sceptics is completely imaginary. "
Big Oil prefer to give their money to politicians and PR firms, not to research. That Big Oil does not fund research suggests that even they think mainstream science is solid.

Very solid. If they had just the smallest bit of doubt, it would pay off for them to fund studies on climate change big time. They have so much to lose that money would be largely irrelevant. They already do much research themselves and also fund much external research. Universities get funding from oil companies for a large range of other research topics. Thus the structures are in place, the money is there.

If I had a good idea and could not get funding from national funding agencies, I would have no problem with accepting money from companies. My university certainly would not.

Not that I not expect to have problems with a research proposal because it would challenge the mainstream. On the contrary, I expect that a proposal that challenges the mainstream would have more chances of being funded. Is anything more beautiful fundamental research? Another rhetorical question. However, maybe for more speculative ideas, that are likely to fail, the profit motive of an oil company could improve my funding opportunities. Most scientists would be happy to use such an opportunity.

Poor climate ostriches, not even their oil companies believe in them.

On the reactions to the doubling of the recent temperature trend by Curry, Watts and Lucia

The recent Cowtan and Way study, coverage bias in the HadCRUT4 temperature record, in the QJRMS showed that the temperature trend over the last 15 years is more than twice as strong as previously thought. [UPDATE: The paper can be read here it is now Open Access]

This created quite a splash in the blog-o-sphere; see my last post. This is probably no wonder. The strange idea that the global warming has stopped is one of the main memes of the climate ostriches and in the USA even of the main stream media. A recent media analysis showed that half of the reporting of the recent publication of the IPCC report pertained this meme.

This reporting is in stark contrast to the the IPCC having almost forgotten to write about it as it has little climatological significance. Also after the Cowtan and Way (2013) paper, the global temperature trend between 1880 and now is still about 0.8 degrees per century.

The global warming of the entire climate system is continuing without pause in the warming of the oceans. While the oceans are the main absorber of energy in the climate system. The atmospheric temperature increase only accounts for about 2 percent of the total. Because the last 15 years also just account for a short part of the anthropogenic warming period, one can estimate that the discussion is about less than one thousandths of the warming.

Reactions

The study was positively received by amongst others the Klimalounge (in German), RealClimate, Skeptical Science, Carbon Brief, QuakeRattled, WottsUpWithThatBlog, OurChangingClimate, Moyhu (Nick Stockes) and Planet 3.0. It is also discussed in the press: Sueddeutsche Zeitung, TAZ, Spiegel Online (three leading newspapers in Germany, in German), The Independent (4 articles), Mother Jones, Hürriyet (a large newspaper in Turkey) and Science Daily.

Lucia at The Blackboard wrote in her first post Cotwan and Way: Have they killed the pause? and stated: "Right now, I’m mostly liking the paper. The issues I note above are questions, but they do do quite a bit of checking". And Lucia wrote in her second post: "The paper is solid."

Furthermore, Steve Mosher writes: "I know robert [Way] does first rate work because we’ve been comparing notes and methods and code for well over a year. At one point we spent about 3 months looking at labrador data from enviroment canada and BEST. ... Of course, folks should double and triple check, but he’s pretty damn solid."

The main serious critical voice seems to be Judith Curry at Climate Etc. Her comments have been taken up by numerous climate ostrich blogs. This post discusses Curry's comments, which were also taken up by Lucia. And I will also include some erroneous additions by Antony Watts. And it will discuss one one additional point raised by Lucia.

Atmospheric warming hiatus: The peculiar debate about the 2% of the 2%

Dana Nuccitelli recently wrote an article for the Guardian and the introduction read: "The slowed warming is limited to surface temperatures, two percent of overall global warming, and is only temporary". As I have been arguing before, how minute the recent deviation of the predicted warming is, my first response was, good that someone finally computed how small.

However, Dana Nuccitelli followed the line of argumentation of Wotts and argued that the atmosphere is just a small part of the climate system and that you do see the warming continue in the rest, mainly in the oceans. He thus rightly sees focusing on the surface temperatures only as a form of cherry picking. More on that below.

The atmospheric warming hiatus is a minor deviation

There is another two percent. Just look at the graph below of the global mean temperature since increases in greenhouse gasses became important.


The anomalies of the global mean temperature of the Global Historical Climate Network dataset versions 3 (GHCNv3) of NOAA. The anomalies are computed of the temperature by subtracting the mean temperature from 1880 to 1899.

The temperature increase we have seen since the beginning of 1900 is about 31 degree years (the sum of the anomalies over all years). You can easily compute that this is about right because the triangle below the temperature curve, with a horizontal base of about 100 years and a vertical size (temperature increase) of about 0.8°C: 0.5*100*0.8=40 degree years; the large green triangle in the figure below. For the modest aims of this post 31 and 40 degree years are both fine values.

The hiatus, the temperature deviation the climate ostriches are getting crazy about, has lasted at best 15 years and has a size of about 0.1°C. Thus using the same triangular approach we can compute that this is 0.5*15*0.1=0.75 degree years; this is the small blue triangle in the figure below.

The atmospheric warming hiatus is thus only 100% * 0.75 / 31 = 2.4% of the total warming since 1900. This is naturally just a coarse estimate of the order of magnitude of the effect, almost any value below 5% would be achievable with other reasonable assumptions. I admit having tried a few combinations before getting the nice matching value for the title.

NoFollow: Do not give WUWT & Co. unintentional link love


The hubris at WUWT.
Do you remember the search engine AltaVista? One reason it was overrun by Google, was that Google presented the most popular homepages at the top. It did so by analysing who links to who. Homepages that receive many links are assumed to be more popular and get a better PageRank, especially when the links come from homepages with a high PageRank.

The idea behind this is that a link is a recommendation. However, this is not always the case. When I link to WUWT, it is just so that people can easily check that what I claim WUWT has written is really actually there. It is definitely not a recommendation to read that high-quality science blog. To the readers this will be clear, but Google's algorithm does not understand the text, it cannot distinguish popularity from notoriety.

This creates a moral dilemma. Do you link to a source of bad information or not? To resolve this dilemma, and make linking to notorious pages less problematic, Google has introduce a new HTML-tag:

<a href="" rel="nofollow">Some homepage</a>.

If you add NoFollow to a link, Google will not follow the link and not interpret the link as a recommendation in its PageRank computation.

Skeptical sunlight

We are not the only ones with this problem. Many scientifically minded people have this problem, especially people from skeptical societies. Note, that here the word skeptical is used in the original meaning. From them I have this beautiful quote:
As Louis Brandeis famously said, "sunlight is the best disinfectant". Linking directly to misinformation on the web and explaining why it is wrong is like skeptical sunlight. ...

I think the correct way to proceed is to continue providing skeptical sunlight through direct linking. For one thing this demonstrates that we are not afraid of those who we oppose. In general they don’t link back to us, and that demonstrates something to casual readers who take note of it. ...

But while we are doing this we must be constantly vigilant of the page rank issue. Page ranking in Google is vitally important to those who are pushing misinformation on the web. It is how they attract new customers to their vile schemes, whether they be psychics or astrologers or homeopaths or something else. Even if we as skeptics are providing only a miniscule fraction of a misinformation peddler’s page rank, that fraction is too much.
Our links are probably the smallest part, but they may be important nonetheless. These links connect the climate ostrich pages with the main stream. Without our links, their network may look a lot more isolated. This is also important, PageRank is not just about links, but about links from authoritative sources.

If you search in Google using:

link:www.wattsupwiththat.com

You will find many pages linking to WUWT that most likely do not want to promote the disinformation, on the contrary.

Anthony Watts calls inhomogeneity in his web traffic a success

[UPDATE. Dec. 2013. The summary of 2013 of WUWT has just been released and the number of pageviews of WUWT has dropped. In 2012 WUWT had 36 million page views, in 2013 only 35 million. Not a large drop, but a good beginning. And it should be noted that a constant readership leads to reductions in ranking as the internet is still growing fast. Thus these number are a clear contrast to the increases in ranking that Anthony Watts announced below.

This confirms that WUWT does not only gives bad information on climate science. Let's hope more people will realize how unreliable WUWT is and start reading real science blogs.]

Success


Anthony Watts pretends to be beside himself with joy. WUWT has an enormous increase in traffic!! In his post Announcement: WUWT success earns an invitation to “Enterprise” he writes: "You are probably aware of the ongoing improvements to WUWT I’ve made. They seem to be paying off. Lately, things have been looking up for WUWT:" and shows this graph.



With such an increase in the quantity of readers, why care about quality? Thus suddenly it is no longer a problem that Wotts Up With That Blog (now called: And Then There's Physics) clarifies the serious errors on WUWT daily.


Comments

The WUWT regulars are cheering.
JimS: Congrats, Anthony Watts. I see that your blog stats have arisen to the level that the AGW alarmists wished the temperatures would also arise to confirming their folly.
John Whitman: The extraordinary ranking of your venue is the best kind of positive energy feedback loop to increase stimulation of critical independent thinkers in every country. You and everyone of them can draw rejuvenating intellectual energy from it. Wow.
George Lawson: The AGW crowd will see this as another nail in their coffin! Almost as painful as this year’s Arctic ice melt.
Stephen Brown: Congratulations! I bet that the rise and rise of WUWT is causing a certain amount of underwear wadding amongst the Warmistas!

Increase?

But is the number of WUWT readers really increasing?

A first indication that this is not the case, is that Anthony Watts did not really write it explicitly. His post and the plot certainly suggest it and he did not correct the people commenting that clearly thought so, but Watts did not explicitly write so. That should make one suspicious.

A second indication is that Watts is very touchy about it. When Collin Maessen, as someone working in IT, pointed out to Watts on Twitter that, Alexa is not very reliable, the response is that Watts blocks Maessen on Twitter.

WUWT not interested in my slanted opinion

Today Watts Up With That has a guest post by Dr. Matt Ridley. In this post he seems to refer to a story that was debunked more than a year ago:
And this is even before you take into account the exaggeration that seemed to contaminate the surface temperature records in the latter part of the 20th century – because of urbanisation, selective closure of weather stations and unexplained “adjustments”. Two Greek scientists recently calculated that for 67 per cent of 181 globally distributed weather stations they examined, adjustments had raised the temperature trend, so they almost halved their estimate of the actual warming that happened in the later 20th century.
I tried to direct those WUWT readers that are interested in both sides of the conversation to an old post of mine about why these Greek scientist were wrong and mainly how their study was abused and exaggerated by WUWT.

Naturally, I did not formulate it that way, but in a perfectly neutral way suggested that people could find more information about the above quote as my blog. I see no way my comment could have gone against the WUWT commenting policy. Still the response was:

[sorry, but we aren't interested in your slanted opinion - mod]

Strange, people calling themselves skeptics that are not interested in hearing all sides. I see that some people from WUWT still find their way here to see what the moderator does not allow. Here it is:

Investigation of methods for hydroclimatic data homogenization

UPDATE: Sou at Hotwhopper wrote a post, WUWT comes right out and says "We Aren't Interested" in facts , about his post. Thank you, Sou. So I guess I will have to keep this post up. And that also makes it worthwhile to add another gem to be found in the WUWT guest post of Dr. Matt Ridley.

Christians on the climate consensus

Dan Kahan thinks that John Cook and colleagues should shut up about the climate consensus; the consensus among climatologists that the Earth is warming and human action is the main cause. Kahan claims that research shows that talking about consensus is:
a style of advocacy that is more likely to intensify opposition ... then [to] ameliorate it
It sounds as if his main argument is that Cook efforts are counter productive because Cook is not an American Republican, which is hard to fix.

Katryn Hayhoe

As an example of how you communicate climate science the right way, Kahan mentions Katryn Hayhoe as an example. Hayhoe is an evangelical climate change researcher and stars in three beautifully made videos where Hayhoe talks about God and climate change.

Except that she also talks about her religion, I personally see no difference with any other message for the general public on climate change. She also openly speaks about the disinformation campaign by the climate ostriches.
The most frustrating thing about her position, she says, is the amount of disinformation which is targeted at her very own Christian community.
Maybe naively, but I was surprised that the Christian community is a special target. While I am not a Christian myself, my mother was a wise environmentally concious woman and a devout Christian. Also when in comes to organized religion, I remember mainly expressions of concern about climate change. Thus I thought that Christians are a positive, maybe even activist, force with respect to climate change.

Thus let's have look what the Christian Churches think about climate change.

Readership of all major "sceptic" blogs is going down

In my first post of this series I showed that the readership of WUWT and Climate Audit has gone down considerably according to social bookmarking site Alexa; see below. (It also showed that the number of comments at WUWT is down by 100 comments a day since beginning 2012.)


reach of WUWT according to Alexa

reach of Climate Audit according to Alexa

I looked a bit further on Alexa and this good news is not limited to these two. All the "sceptics" blogs I knew and had statistics are going down. Bishop Hill, Climate Depot, Global Warming, Judith Curry, Junk Science, Motls, and The Blackboard (Rank exploits) are all going down. Interestingly the curves look very different for every site and unfortunately they show some artificial spikes. Did I miss a well known blog?

Decline in the number of climate "sceptics", reactions and new evidence

My last post showing that the number of readers of Watts Up With That and Climate Audit are declining according to Alexa (social bookmarking) has provoked some interesting reactions. A little research suggests that the response post by Tom Nelson: Too funny: As global warming and Al Gore fall off the general public's radar, cherry-pickin' warmist David Appell argues that WUWT is "Going Gently Into That Good Night", could be a boomerang and another sign of the decline. More on that and two more indications that climate change ostriches are on their way back.

Public interest in climate change

An anonymous reader had the same idea as Tom Nelson, but did not write a mocking post, but politely asked:
"how do you know it is not a general diminution of interest in climate change?".
That is naturally possible and hard to check without access to the statistics of all climate related blogs and news pages. However, as you can see below, the number of readers of SkepticalScience and RealClimate seem to be stable according to Alexa. This suggests that the decline is not general, but specific to the "sceptic" community.
