ryland @41, the problem with Lomborg is not that he studies how best to tackle global warming, nor even that his proposed solution isn't a solution. It is that his "research" in support of his conclusions is distinctly second rate, and probably constitutes academic misconduct. I have quoted other peoples opinion on this here and here, but I have not read his books and must rely on their opinions in that regard. However, one issue I have looked at is the use of different discount rates in the "Copenhagen Consensus".
Kare Fog gives the story:
"4) Inconsistent use of discount rates
The experts were instructed in advance to use two discount rates, viz. 3% p.a. and 6 % p.a. That is, the benefit/cost ratios are calculated twice, once with the low rate, and once with the high rate. In practice, however, only the results obtained with the low rate (3 %) have been used in the conclusions. So, the high benefit/cost ratios for the many programmes in the fields of health, nutrition and diseases were calculated using a discount rate of 3 %.
The only exception is in the field of global warming. Here, Yohe et al. use a discount rate of 5 %, gradually declining over 100 years to 4 %, whereas Green uses 4 %.
Why did the climate specialists not use the prescribed discount rates? As to Yohe et al., the explanation given by the economist Richard Tol here is as follows:
"On the discount rate: I do not know what the other papers used. We used a consistent discount rate — all calculations, and all reporting was done with the same discount rate. The models that we use would require extensive recalibration for a different discount rate. . . As we used dynamic optimization models fitted to observations, we had to stick to the discount rate we had. As the rest of the Copenhagen Consensus used simpler methods, they should have used our discount rate."So Richard Tol thinks that all other specialists should have used the discount rate that gradually declines from 5 % to 4 %, because his group could not easily adapt to the prescribed 3 %, whereas it would have been relatively easy (?) for all others to adapt to his group´s discount rate. In any case, the result is that the disocunt rates are not comparable.
As to Green, he performed his calculations with a 4 % discount rate, but also included results for a 3 % discount rate.
Now, when all data for all items were summarized and compared, all other projects were represented by the benefit/cost ratios obtained wit a discount rate of 3 % (the results with a 6 % discount rate were not used in the final evaluation). Only the climate projects were represented with different discount rates. And these rates were higher than those used for other issues. Which is against the usual thinking that the longer the time perspective, the lower must the discount rate be. As the climate issue has the longest time perspective, it should have the lowest discount rate.
This is especially remarkable in the case of Green´s project. Here there existed a version where a 3 % discount rate was used, but in spite of this, the version included in the final ranking was the one using a 4 % discount rate. And that matters quite a lot. As stated in the previous paragraph, for Green´s project, 4 % yields a benefit/cost ratio of only 16:1, whereas 3 % yields a benefit/cost ratio of 28.5:1. Which would have brought Green´s climate project near the top of the ranking list, above the efforts against tuberculosis, malaria, child diseases and heart diseases. The climate project would have got a priority near the absolute top. But the slight change in discount rate, from 3 % to 4 %, sent the climate project far down along the ranking list, out of the range of projects that are granted money.
Incidentally, this is the same situation as in the Copenhagen Consensus 2004. There, the discount rate used for the climate issue was 5 %, whereas that used for HIV/AIDS was 3 %.
So there is an obvious reason why the climate issue always is ranked last. It is systematically treated with a higher discount rate than the other issues.It would of course be interesting to hear Lomborg´s comments to this criticism. And indeed, he has been forced to comment upon this in a debate in a local Danish newspaper in February 2009. See here."
On this, I have verified independently that Tol in fact used a higher discount rate than was used examining other projects considered by the Copenhagen Consensus, and that that materially alters the priority rating of takling global warming as compared to those other projects.
In the case of Tol's paper, that may just be Tol's fault, although Lomborg ought to acknowledge the problem, something he seems determined not to do. But in the Green case mentioned above (which I have not independently verified), the choice to use the valuation based on the 4% rather than the 3% discount rate was Lomborg's, and amounts to academic fraud.

@CBDunkerson, What an excellent question!
"Obviously, 'inoculation' is a useful tool to halt the spread of misinformation, but how do you get through to someone who has already been successfully inoculated against reality?"
I've been teaching a form of counselling for 30 years. I'll give you my take on it.
I think we need to start with the common personal decision making aparatus - feelings. Most people from my experience decide most everything based on their feelings. Feelings can be manipulated to be made up of a large part of the past so the person walks around with a pseudo-reality made up of old attitudes and painful emotions as if it's all real. These become self perpetuating. Self fulfilling justifications.
As an example - an argry man can become convinced that everyone is defensive. If they are not defensive in the first second of a conversation with him I expect they will be by the second or third second.
I see ideologies as being the pseudo realities that hold all the painfull past in place. When a person is very relaxed and open I don't have much trouble with a sensible discussion of climate change. Very few are that relaxed and open!
The world views I've come across occupying climate denial are those of the right wing, the religeous evangelical, the haters of communism, those working for fossil fuels. Of course a clear headed right wing, evangelical anti communist fossil fuel employee could be an ally to climate science. It's about cultural blind spots.
A workable path out of this blocked up pseudo real life is through relationships that have trust and humour. Once those features are in a life - a relationship with someone who does know about climate change science and who is also trusted personally, humour is able to be used to begin to break up the rigid mass of the pseudo real. The ideological blocks of pain filled attitudes after a big laugh are loosened up for a little while.
With skillfull humour and a good relationship the approaches that John Cook discusses become with in reach. Then his recommendation about weak denial inoculation looks work able to me. Having done that with denialist friends I know that it's possible for me to acheive that.

Perhaps, I have missed the purpose of this thread and should not have posted as what I'm saying is not exactly in line with the discussion. This is about Lomborg's h index, which is an index that is totally independent of his credentials related to CC and what he says. It is also about whether he deserves to be given 4 million dollars by the Australian Government to establish his research centre in Australia and further obfuscate the CC debate.
Now, if this an esoteric discussion purely about academic credentials amongst academics, then I am happy to take your point. This, unfortunately, is not going to enlighten the wider public about the quality of a CC argument, who these academics are and what they are saying. In fact, in Australia, most CC related comments that make it to the wider public are mostly by non climate scientists writing denier based articles in the Murdoch press or comments made by right wing shock jocks. While Sks does conduct a proper balanced debate based purely on the science, the economics and social impact; this debate does not filter into the public forum because, in Australia, the mostly denier/skeptic comments get a free unchallenged run because those putting up a more balanced position have been hounded out of the public forum with torrents of abuse and trolling. In other words the public do not get a balanced view based on the science. I am not suggesting that some CC credential for CC scientists be used to select scientists for research centres, the h index should be enough. Also, I would be fairly sure that Lomborg probably doesn't use it or would use any other artificially CC related credential. I would be pretty sure that he would select his academics using his own criteria. What I am saying is that the wider public do need some way to assess the quality of a CC article in the public forum. Unless climate scientists properly engage in the public debate then they will well and truly lose the debate despite what they might be arguing in purely academic circles. In public forums in Australia, it's too easy to be a denier. It should not be.

ryland @ 41...
The challenge comes with the "at least in part" aspect of his position. Over the years it's become undeniable that climate change is, in fact, happening. So now the default denial position is that it's happening and humans are responsible "at least in part." This is not much of a shift in position. Lomborg still says that we should continue to burn FF's because not burning it would hurt the poor, which is a position that's not supported by research.
Catch that? The shift in position is there to make higher profile climate deniers sound credible, while their position on any kind of action to limit carbon emissions remains completely unchanged.

ryland @39, first, Lomborg purports to be an expert on environmental issues including global warming. Ergo Cook and Dana are in the same field as his purported area of expertise. However, his actual area of expertise (in as much as he has one) is game theory. Therefore for comparison I did a google scholar search for game theory and here are the first to authors registered on Google Scholar from that search:
So exactly was your point?

ryland at 08:17 AM on 28 April 2015Lomborg: a detailed citation analysis
I was under the impression that Lomborg fully accepts both the science of climate change and that humans are responsible at least in part. I thought his field was not climate science per se but how humans could best adapt to climate change and the cost benefits of various approaches. I can't see how this is reprehensible or in any way undermines what climate scientists promulgate. In fact it seems to complement their efforts as he is saying the effects of climate change are going to be manifested so how can we best deal with them.. I cannot understand why there is such antipathy for an appointment that has little to do with the science of climate change and a lot to do with how best to cope with it.

Tom Curtis at 08:13 AM on 28 April 2015Inoculating against science denial
Tom Dayton @2, a further nitpick. "x implies y" if, and only it cannot be the case that x is true and why is not, ie, if x is sufficient for y. You can flesh out "cannot" as a logical relationship or a causal relationship, but "implies" indicates sufficiency in either case.
It is true that nowadays there is a common meaning of "implies" which means merely that it hints at, but that is not the meaning used in the the common claim that "correlation does not imply causation". Indeed, it is probably a bastardized meaning that comes from the inflation of language evident when you see politicians or reporters say that they "refute an accusation" when they merely mean that they reject it (as if, like God, their claiming something makes true). (A refutation, of course, reqires the actual giving of evidence (ie, a rebutal), and the evidence actually proving the point,ie, that the rebutal is successful, and not merely rhetorically).

Rob Honeycutt at 07:23 AM on 28 April 2015Lomborg: a detailed citation analysis
ryland... The issue here is that Lomborg's publishing record on climate – the subject matter of the center he's being funded to lead – is nearly non-existent.
Perhaps his h-index is more in line with those publishing on game theory (the subject of a couple of his papers), but I would doubt that's even the case.
-
ryland at 07:12 AM on 28 April 2015Lomborg: a detailed citation analysis
The comparisons made by Bradshaw don't seem to take any account of the h-index in different disciplines. It is all very well contrasting Lomborg with Nuccitelli or Cook or whomsoever but such comparisons are largely meaningless. Why is there no comparison of Lomborg with others in the same field? It is claimed that the h-index has a strong discipline biasand that comparisons should be made after normalisation via h/(h)d where h is the individual's h-index and (h)d ther average h-index for the discipline. Was that done? If so I obviously missed it. Overall this seems a comparison of grapes with car tyres. Not one of the better articles in SkS

Full disclosure: I am non-religious, in the usual sense. Attacking religion is a bad idea. After all, we are faced with a situation where the universe and human interests are not aligned. We die. We suffer injustice. We suffer from imperfection. We drop our keys in the toilet. We can understand all of these conditions from a scientific perspective, but it won't stop us from trying to build narratives to cover the basic fact that human interests and the universe are not aligned. Any single version of the religious narrative may be wrong from a scientific perspective, but it may be critical to remaining sane in bewildering conditions. The non-religious have their own fictions, of course, and for the same reasons. One of the great questions of the 20th and 21st centuries is whether or not the value of the individually-derived narrative will rise above the collectively-derived narrative. We'll still be telling ourselves stories, though, regardless.
Note, of course, that this doesn't mean we shouldn't act on the best information--presumably what science provides, and religion shouldn't try to describe the physical universe. What science doesn't provide is meaning and purpose. We have to figure those out for ourselves. -

@Sunspot
Be careful about such claims. Yours are after all a form of dogma as well. The idea that science and faith cannot exist simultaneously did not really come into existance until the Skopes trial. However I would say that attempting to refute science using little more than faith cannot succeed on its merits.However, I might be willing to argue that science cannot exist at all if viewed through a political lens.

...certainly are a lot of comments about Herr Lomborg, hereon. Australia supports more climate deniers than (seems) most other nation-state "entities" (John's associates and most of y'all herein from "down under" notwithstanding), but will Lomborg, in the end, really matter? Deniers are all about the status of their wallet, that status always more important than anything else...even their children's future. ...Don't think that can be changed. We've stated the inevitable...let's proceed to arrange our lives and the lives of those over whom we have effect and let the climate Devil take the hindmost. After all, six billion less humans on the planet would put us about where survival for the remaining billion would be virtually assured. Jared Diamond, essentially asserts that human societies collapse when faced with insurmountable survival obstacles...how will hand wringing about the likes of Lomborg, et al? really change that?

CBDunkerson at 04:30 AM on 28 April 2015Inoculating against science denial
Unfortunately, it seems to me that it is just as possible (perhaps even easier?) to 'inoculate' people with misinformation.
Look at the whole, 'The hockey stick is broken' myth... setting aside the fact that it is false, even if the 'hockey stick' had been erroneous, that would not have contradicted our understanding of AGW at all. Yet, 'skeptics' are able to take a less than optimal statistical technique (i.e. principal component analysis) in MBH 98 and use that to inoculate people against the study as a whole... and then leverage that rejection of the 'hockey stick' into rejection of AGW as a whole. Denial built upon delusion built upon misinformation.
We see the same thing with Himalayan glaciers = IPCC false = no AGW and various other 'skeptic' arguments. It is the same concept of knocking down a weak argument to take advantage of human tendency to then reject the entire line of reasoning... just with the addition of the original 'proof' itself being false.
Obviously, 'inoculation' is a useful tool to halt the spread of misinformation, but how do you get through to someone who has already been successfully inoculated against reality?

That's not what I've been saying. I thought it was quite clear.
Setting up a screening process to only let in researchers with a pre-existing and narrowly selected point of view is counterproductive to the goal of establishing a credible research center, regardless of your criteria for the viewpoint screening. If it's credibility you're after, then you do not want to establish an ideological filter ahead of time, period. The only appropriate filtering would be to winnow out those researchers who are clearly out of touch with the evidence, the data, and the best available sciencce. That's about simple qualifications, not a nebulous purity test based on agreement with a statement of faith about climate policy.
Everything else you're saying is just expressing frustration with the popularity of think-tanks that only serve denialist interests and doesn't address the point.

Only to people who place their "trust" with no concern for reality. The only way to show that their 'trust' is misplaced is to provide the facts... i.e. 'exactly how warm or not the MWP' was. If you show that there was no global MWP (as the article above does) and people still respond that you are 'hiding' this thing which does not exist (as you argue they will) then those people are delusional. They aren't engaging with the facts, but operating solely on 'who they trust'... even when those trusted sources are shown to be false.

RedBaron at 14:51 PM on 27 April 2015There's no empirical evidence
@Tom,
You said, "Soil sequestration will peter out more slowly, but will itself reach equilibrium over time." Maybe. I would like some evidence that aside from the atmospheric CO2 levels reaching ~170ppm +/- that there is any reduction in healthy grassland ecosystem's sequestration of CO2 in the soil.[1] Overgrazing can cause a reduction. Undergrazing can cause a reduction.[2] But judging from the actual evidence and the cause of carbon sequestration[3], I seriously doubt there is any "petering out" of carbon sequestration as soils improve. Here is why, one of the primary reasons for such increased soil sequestration of carbon in grassland soils is the mycorrhizal fungi plant symbiosis. This effect is not dependant on carbon already sequestered, but instead a direct feeding of products of photosynthesis to the fungi and it has a direct relationship to grazing pressure.[4] I conclude that the reason Savory, Sacks, Teague, and several others are seeing a difference in the sequestration rate differences according to management practices is this symbiosis. They also are finding the quantity of carbon contained in soils is directly related to the diversity and health of soil biota. This correlation deriving directly from root exudates which feed the mycorrhizal fungi, which then produce glomalin.[5] Unless you can show any break in that cycle (other than atmospheric CO2 levels dropping below what C4 plants can effectively use as generally happens) that might occur when soils reach a certain level of SOM, there is no reason to believe sequestration will "peter out" in the soil. Unless you can back up that assumption. Keep in mind you would also need to show there even exists enough CO2 in the atmosphere to reach any kind of plateau like that.
You also said, "It is thoroughly implausible that so sensitive a feedback mechanism would not either act as an inexorable pump of CO2 levels down to far below preindustrial levels, or result in wild fluctuations in CO2 levels on an annual and decadal basis."
And yet atmospheric levels have experienced an inexorable pumping down well below those levels. It happened every glaciation phase but this one. What stopped it, if not the megafauna extinctions? Remember we have evidence that both overgrazing AND undergrazing reduce carbon sequestration in grassland soils and about the same general time the megafauna extinctions occured, the CO2 levels stopped dropping. Much later they started rising significantly. Analogy would be a draining pool. First you plug the drain, then you begin filling. Soon it will overflow. But if you hadn't stopped the drain when you began filling it, likely it wouldn't overflow. It just wouldn't empty. The reason your models are flawed is because you are measuring the stoppered pool and assuming this is the extent of the drain. Instead you must measure a cleared drain to calculate what fill rate will make it overflow. This is the relationship of the grasslands ecosystems which are the primary driver of global cooling and fossil fuels which are the primary driver of global warming. In order to make a proper compareson you need measurements of fully functioning grassland ecosystems that are not over grazed or under grazed, and certainly not tilled. There are only a few such measurements available, but the ones available seem to indicate that the "drain" when cleared is significantly bigger than the "fill".

DSL @2, Roman Mureika is a statistician that frequently comments at Climate Audit, being very critical of anyone disagreeing with McIntyre. As a rough measure of his ability, he has an effective Google Scholar h-rating of 6. Most of his papers deal with the ins and outs of record times for 100 meter sprints. For comparison, Grant Foster who is belittled on Climate Audit as a statistical nobody in comparison to Mureika has an effective Google Scholer h-rating of 10. What is more, unlike Mureika, he has published on the temperature record.
The GWPF is certainly stacking the deck with people with a known outlook. As Nick Stokes points out, they have also stacked the deck with the questions they put to the inquiry.
Having said that, van Wijngaarden has an academic record that certainly justifies his being on this sort of panel, including publications on climate statistics. Based on his publication record, he at least is unlikely to perform a simple hatchet job.

I agree with you that it would be difficult to create some index to assess climate researchers and commentators, because what ever method you used would be modifiable by others to suit their purpose which, in the end, would make the index next to useless. It's a bit like the many so called fancy sounding pseudo scientific climate research centres that have come into existence to deny AGW, that, in reality, are little more than sophisticated marketing centres rather than serious scientific research institutions. It seems, from the article, that the h index is also open to interpretation, but at least academics do have some understanding as to its meaning. Also, it seems, that academics are able to assess the relative merit of research and comments made by their peers, and as such do not need an index of assessment other than the research they have done and the statements that they make.
However, to those outside academia, all this is very confusing. Assessing what has merit and what doesn't is very difficult for the lay person or merely interested to assess. Having some index would be helpful, although it would be difficult to create a consensus about an index of credibility. In the CC/AGW debate it is not so clear cut, so the realities of that debate are taking much longer to penetrate the public conscience. It took about 100 years for continental drift theory to become widely accepted in the public conscious. Unfortunately, we don't have the same 100 year time frame to create a public consensus in the climate change debate so that it becomes widely accepted in the public mind so that proper public policy can be implemented to alleviate the worst impacts of AGW and CC. It might be easier for the public, if there was actually some easily assessible CC CV so that the relative merits of the various arguments can be more readily assessed. In Australia, there will be many outside science/economic circles who are cheering the appointment of Bjorn Lomborg to lead this 4 million dollar government funded research centre because it suits their politcal point of view.
In Australia we don't need more commentators advocating non-action. The sad part about all this is that that 4 million dollars would probably be better spent searching for alternative methods of energy generation. In fact, the efforts to find alternative, more sustainable, less emitting forms of energy, considering the time frame needed, amounts to little more than tokenism. I find it incredible that the Blue Horizon platform that blew up in the Gulf of Mexico and messed up the coast line, cost 5 billion dollars. It had to drill through a kilometre of water and a kilometre of rock to get to the oil, an amazing technology showing it can be done. However, the Australian government has allocated less than half the cost of the Blue Horizon platform to alleviate carbon dioxide emissions and create alternative energies. It seems to be the same with all greenhouse gas emitters. They fund token efforts. They should be leading the charge in finding alternative energy technologies, not funding deniers in some mickey mouse pseudo-scientific so called research institute. All I have seen so far is mere tokenism and mere tokenism is not going to reduce CO2 emissions. It will take public action from an informed public, not more denial. I do not have much faith that mankind will do what is necessary.

Just to add a point on plate techtonics (though I know it's off-topic)...
Part of the challenge there was coming up with solid evidence of plate techtonics. The idea was fantastic, but for a very long time it wasn't accepted merely because there was little data that supported it. It took many decades to pull together the data that was sufficient to convince the scientific community.
And that is how it's supposed to work. When the evidence is there, scientific consensus can actually move fairly rapidly.

PluviAL@30 said: "something motivates... [Lomborg] and his supporters, and it is not just money." You claim open-mindedness. Open your mind to the possibility that it is, in fact, just money. Even consider the possibility that Lomborg, himself, may not know it. He is skeptical, he says so, and money flows his way. Why wouldn't he continue down that path that has worked so well for him? According to this article, "Lomborg operates by attaching himself to these centres as an adjunct professor... rather than a staff member. This offers the freedom to command remuneration well above a professorial salary – such as the US$775,000 he was paid in 2012 by... [his U.S. based Copenhagen Consensus Center] and the US$200,484 paid... in 2013."
As regards Lomborgs economic arguments, I'm reading 'Climate Shock' by economists Wagner and Weitzman. Once CO2 rises to 560ppm (this is almost certain by 2050 or so), the probability of hitting 1.5C to 4.5C is 66% (IPCC estimate). But that probability has a positively skewed distribution with a high end 'fat tail'. Assuming a 6C rise means mass extinction (very likely) and profound disruption to the global economy (also very likely), then there is already a small (0.04%) chance of hitting 6C already, at todays 400ppm CO2. But, by mid-century, at 560ppm, that probability increases a hundred-fold, to 4%. That's a 1-in-25 chance, higher odds than of hitting 'snake eyes' when rolling two dice. And that level of risk is already 'dialed in' because we can't 'decarbon' the economy fast enough to avoid it. A game-theorist should understand 'Pascals Wager': why risk a 'wait-n-see' on carbon, if the punishment is eternal damnation? As the authors state "The appropriate price on carbon is one that will make us comfortable enough to know that we will never get to anything close to 6C."

Pluvial, we are discussing science here, politicians and non scientists might like to hear about "alternatives". However, in science, any alternative must be based on accepted science. Lomborg's "aternatives" are not based on science but on ideology.
Also where did you get this from:The best scientists of the time were still working with various version of the shrinking continents theory.
Continetal drift theory did not involve "shrinking continents", it was not accepted at first because no-one could come up with a method for the continets to move till plate techtonics was discovered and described.
Your last paragraph is just gibberish I'm afraid. Stop pretending to be knowledgeable about science when it is obvious you don't have a clue.

As expected, your response is far better than my effort. No doubt you are right in every respect except this: People want to hear alternatives, especially politicians, and others of us on the outside. I have read both his books, and not being a very critical reader, I was somewhat convinced.
You see my method contrary to bozzza's argument is not really madness, it is open mindedness. OK, Lomborg’s arguments are soft, and maybe even systematically disingenuous, after all he is a game theory student. However, we still need to hear what he is trying to get at, something motivates him and his supporters, and it is not just money.
We can illustrate the linearity trap which the conventional science community is subject to by observing the long time it took to consider today’s conventional tectonic plate theory, which is substantially defective even today. The theory was proposed decades before it was seriously considered. The best scientists of the time were still working with various version of the shrinking continents theory, which is really absurd in retrospect. It took so long to consider it because the stiff scientific method, and its propagation process, is linear. This means that only accepted lines of inquiry are accepted, and that anyone who steps outside the bounds is castigated, with threat to their credibility and thus their livelihood. Is that any less negatively motivating than what Lomborg exposes himself to? I do appreciate your sincere statement that erroneous offers are valualbe, but it is not practiced enough
Consider this: You are to bet civilization’s future on the outcome of one sumo match. One side is the current champ and favorite at 44 lbs. On the other is the challenger he weighs in at 174,000 lbs. but everyone knows he is slow, except for you. You know he is cunning and can move fast if he chooses. Who will you bet on? Well, conventional science still puts our lot on the little champ, earth flux. The big guy is insolation and gravity effects from the sun and moon, which can express themselves through ice loads and other climate loads on the continents. The mechanics for expression are far better than core convection. If this is right, in the future it will be as absurd to look back on current theory as this fight, or the shrinking earth theory. Each day more information comes up favoring the big guy, and the consequences of the of the resolution are urgent and tremendous, yet it is still ridiculed by main line science and largely ignored. That’s a fault resulting from the linearity of the method, and its propagation process.

mancan18, nothing you said really addresses the issue I brought up. In fact it seems more like doubling down (reasserting what's been challenged without providing a new argument or rebuttal).
The problem with your solution is that it leans too far into the realm of purity tests. What you're essentially coming back with is that we need purity tests. In reality, that's detrimental to the credibility of research centers.
To put it another way, think of the anti-evolutionists. They often have "research centers" designed around religious Apologetics, and one of the mechanisms they use to ensure that their "researchers" stay on the straight and narrow ideological path is to implement a Statement of Faith. Potential Apologists have to agree to a set of beliefs from which they aren't allowed to deviate while remaining attached to the Apologetics outfit. This behavior has long been pointed to as a black mark against their claims of credibility by the scientific community.
By asking for a similar pre-screening test about an individual researcher's beliefs upfront, you are implicitly pushing for something that would harm your hypothetical research center's credibility the same way. It essentially functions as a restriction of academic freedom imposed on anybody you'd like to hire.
It's one thing to reject candidates who brazenly dismiss the reality of gravity. It's another thing to test candidates based on their existing commitment to a preconceived political plan of action and specific metrics like "safe levels of carbon." The latter is absolutely not something you want to do if you're setting up an institution with the express purpose of finding good solutions through research. You want to attract researchers based on their being productive, engaged people who are passionate about the question, not based on how wedded they are to particular policy viewpoints ahead of time.
In the end, it would be coutnerproductive to your goal of making the most credible and trusted source of information for the general public. Such a research center would be tainted by the perception of being packed with partisans and ideologues rather than picking the top scientists based purely on their capabilities.

One Planet Only Forever at 02:26 AM on 27 April 2015Lomborg: a detailed citation analysis
A scientifically rigorous method of evaluating the merit or contribution of individuals is appealig. However, the measure of the contribution of anyone in humanity (in science, business, politics or any other field of endeavour), needs to be how 'helpful' their contribution was toward the development of a lasting better future for all of humanity. And it is clear that the only lasting future for humanity is through learning how all of humanity can be a sustainable part of the robust diversity of life on this amazing planet (or any other planet that humanity succeeds in reaching).
With that in mind, a better test of the legitimacy of a contribution would be how it adds to the advancement of humanity toward that lasting better future for all life. Anyone who simply was unaware of the 'unhelpfulness' of their efforts would have their misguided contributions given a zero value (giving the benefit of the doubt that the individual simply lacked awareness or understanding). And 'unhelpful contributions', including contributions that would mislead less aware or less informed people would be given a negative value, with the magnitude of the negative assessment being related to the degree that the individual should have 'known better' or been able to be informed enough to better understand the 'unhelpful nature' of the claim they tried to make.
A more common sense approach would be to simply focus on identifying who has been 'unhelpful' and have laws in place to formally remove deliberately unhelpful people from positions of significant influence in humanity (in science or business or politics or any other human endeavour), regardless of the momentary popularity or profitability of what they are trying to get away with.

Pffft. Much ado about nothing. Lomborg's work is of such low quality and significance that, without the eagerness to prop him up and create baseless "controversy" he would have gone compeely unnoticed. In one of his earlier brushes with serious scrutiny (i.e. by official bodies), he was found to be "not even wrong." In other words, the work was so poor that one could not establish an intention to mislead with any certainty. Not much of a contributor to Human knowledge. I won't cite, this is sonmething that has alreadybeen discussed here on several occasions over the years.

PluviAL @23, Bjorn Lomborg can only have made a valuable contribution to the debate if the accusations against him are false. Accusations such as those by J van den Bergh (quoted by me above). Or this accusation made by Dan Wenny in Natural Area's Journal, 2002:
"Many of you are no doubt familiar with the claim that a significant proportion of earth's species will likely go extinct in the near future as a result of habitat loss and other effects of economic development unless action is taken. Lomborg's strategy of rebutal is simple: (1) start with a false comparision; (2) distort the data and selectively compile evidence to knock down the straw man; (3) use questionable sources, citations out of context, and irrelevant examples while ignoring most of the scientific literature."
The charges are serious, and amount to a claim that Lomborg mounts his case by a process of scientific misconduct, not too dissimilar to that found among the writtings of creationists. A review in Nature by Jeff Pimm and Stuart Harvey was harsher, saying that in the Sceptical Environmentalist "the text employs the strategy of those who, for example, argue that gay men aren't dying of AIDS, that Jews weren't singled out by the Nazis for extermination, and so on." (Quoted from wikipedia)
I have not read the book, so I do not know that the claims made against it are valid. I do know that they were made by people with firmly established reputations of quality researh in their fields. I also know that they claims were validated by the body established by the Danish government to adjudicate cases of scientific misconduct. (That that adjudication was overturned by a political body, ie, the science ministry carries little weight with me - particularly considering that the purported grounds of overturning the adjudication effectively damn the Sceptical Environmentalist in any case.)
I also know that Lomborg is certainly guilty of the one most basic tactic of creationists, and AGW deniers, and the rest of the whole pseudo-scientific crowd - of taking his case to non-experts before taking it to experts. I view that as a tacit acknowledgement that the people who knew enough to assess his argument would find it bad.
That being the case, no government should appoint him to any academic position except as a result of normal, armslength selection proceedures. And if they do, it is because they do not want research on the topic, but a ready supply of press releases.

I would think, given the currently very odd trajectory of Arctic sea ice as of the 24th of April , that more questions would best be avoided by the Abbott Government at this point in time.
Tony Abbott can't even answer questions about the NBN- how is he going to explain the very odd trajectory of Arctic sea ice undermining his every stammering slogan?
When do we hear from Lomborg about this Arctic sea ice thing and how best Australian tax-payer dollars are spent on avoiding what looks like a very bad trend from getting worse?

I am not saying that being wrong in science is a problem. Its not. In fact it normally leads to better understanding and a science that is more robust. I am also not saying that the h index is not an important measure to determine the credentials of professional academics. I was being devil's advocate in suggesting a SLC (safe level of carbon dioxide) index for those who enter the climate change argument. While the h index should be enough amongst professional academics to assess credentials, it does not help those outside academia in assessing credentials. Some form of SLC index would at least inform outsiders about the merits and positions of the various advocates. Or perhaps some CSC (Climate Science Credibility) credential based on the Consensus Project might be more useful in assessing climate scientists. Again I am being devil's advocate. Amongst climate science commentators, there is a huge difference in climate science credentials between the likes of Andrew Bolt, Richard Lindzen, Ian Plimer, Bob Carter, David Karoly, James Hansen, Judith Curry, Al Gore, Tim Flannery, Bjorn Lomborg and the various scientists who regularly contribute to sites like SkS. Unfortunately, for outsiders, there is a lot of noise which is hard to penetrate and creates doubt that allows any politically motivated denier to drive a truck through the arguments. There needs to be a simpler measure for the wider public to make an assessment as to the quality of what is being claimed. After all, those who believe the level of CO2 is not the key issue in the whole debate probably should not be given any credibity in the discussion. Because at the moment, we are right on track to release the CO2 that was naturally sequestored in the Earth's crust over millions of years in a little over 300 years putting CO2 levels not seen since the dinosaurs. Now anyone suggesting that this is a good thing needs to have their arguments closely scrutinised.

I have to be heretic once again: Admitting that most commenters here are better informed, write better than I, and are more rigorous in their arguments, it still seems Bjorn Lomborg makes a valuable contribution to the discussion. This means that science minded people have to be more open to sincere alternative arguments. Not denying that Lomborg has compromised motivations due to the funding of his institute, who does not have funding issues? The whole excessive concern with h-rating is an indication with the lack of a good index by which to gage value of communications. There is value in communications other than scientifically sanctioned papers. We just don’t have a good way of appreciating these. Science is too linear, by necessity. The arguments about climate change are global, even on the scientific side. That is why the models are so hard to pin down. When we consider economic, social, urban architecture (the dumb car city), political, market, and infrastructural inertia, and so many other issues which Lomborg tires to get at, we can see value that he brings to the table.
So, yes, he is an asset to a faculty. How much, we will have to see, and he will have to determine.

mancan18, there is no problem with being wrong in science. By the nature of what they do, scientists must be wrong a good percentage of the time. If not, they are not properly exploring the issues. What is not acceptable in a scientist is being wrong in uninteresting ways - ie, in a way that can be refuted by current knowledge, that does not require further research to show that you are wrong. If that is the case in a given paper, it will generate very few responses, and no citations (other then self citations) and consequently have a very low citation number.
The advantage of the h index is that you can publish a thousand papers each with 2 citations and it will not lift your h index above 2. Therefore being consistently wrong in uninteresting ways will not generate a high h index. And being consistently wrong in interesting ways means you are a productive scientist.

Tom Curtis at 13:04 PM on 26 April 2015Lomborg: a detailed citation analysis
Peter Lloyd @17, Lomborg has just been granted 4 million dollars by a government that claims to be in a budgetary crisis. That crisis has been sufficient to justify, in the governments opinion, the defunding of a Climate Science advisory body, to introduce massive cuts to Australia's premier research body (CSIRO), and to try to introduce cuts to university funding in general. Further, the grant was not initiated by a university, or by application to Australia's academic grants body (the Australian Research Council). It was not even initiated by the Minister of Education. Rather, it was initiated in the Prime Ministers office.
Given that the grant was an endrun around normal methods to ensure research quality, it is reasonable to ask what sort of research quality can we expect. The h index gives an indirect measure of research quality, and by that indirect measure it is shown that Lomborg's "research" is effectively non-existent (only 7 papers to show for almost 20 years research) and of very low quality (h-index of 4, h-index of climate related papers of 0). On this basis, and given the political nature of the grant, it is reasonable to conclude that Lomborg is being given the money for what he says, not for how he backs it up.
Pointing that out is not playing the man.

Peter Lloyd, you're wrong. This is entirely about Lomborg's work. It is about his publications, how much they have been cited, how relevant they are to the debate. It is about how misleading and how damaging his work has been. The comment just above is about the miserable lack of knowledge demonstrated in chapters of Lomborgs book in which Daniel has expertise. The comment above that one says nothing about the person and is somewhat off topic. The previous one (16) states that Lomborg leans a certain way in the debate considered and was likely chosen because of that. How does it attack the person? Lomborg advertises his convictions loud enough that stating them here is hardly a personal attack. The previous comment (15) argues the merits of the entire premise behind Lomborg's argument and others similar in reasoning. Above that we are a little more on topic, which is Lomborg's true qualifications for the position he was awarded. These are a rather objective matter, especially when considered through the normal means used to assess such qualifications. One can be whoefully unqualified for something and still be a nice person. Stating that they are not qualified does not constitute a personnal attack. Your statement has no basis whatsoever.

Lomborg's book The Skeptical Environmentalist was most emphatically not peer-reviewed. If it had been peer-reviewed, they would have demanded rewrites to correct his numerous errors and misconceptions and his dead-end citations. Some of his chapters fell into my area of expertise. They were pitifully erroneous on different levels (actual factual errors, misunderstandings of facts and ideas, incorrect citations, misrepresentation of definitions and current knowledge). He wasn't quite as bad as the "evolution is just a theory" level of ignorance, but he certainly was still wading around in the ignorance pool even if not standing in the deep end.

WheelsOC, I know a SCL index would clearly indicate where you/they stand, but that is the whole point. It seems climate deniers can make all sorts of outrageous claims, yet never have to justify their stance, scientifically, and are able to remain non-commital about what they think should be a "safe" level that we allow the CO2 level to rise to.
Now I'm no climate scientist, I'm a mathematician, but from all the articles from bona bona fide climate scientists that I've read and evidence and adverse effects that I have gone through particularly the paleoclimate evidence, I think it is about time we were seriously trying to reduce emissions, because further increases, particularly at current and increasing rates, are leading us into some pretty adverse territory and the unknown. Waiting for certainty, as the climate deniers seem to advocate, although it is not a valid scientific position to take, is most likely bite us in ways that we probably haven't imaged yet. Because, sure as eggs, the Earth's climate system, although we are gaining a greater understanding of its processes, will still have some surprises for us that we probably won't like.
At the moment all we have are indications, and what we do know for certain is that over the last century or so; CO2 levels have increased 40% due to burning fossil fuels and other human activity; average global temperatures have risen about 0.8 degrees celsius; the ocean level has risen about 20 cm; polar ice is slowly retreating; storms seem to be intensifying; seasons seem to be slightly out of kilter; the tropical and temperate climate zones seem to be slowly advancing towards the poles while the polar zone seems to be contracting slightly; and some species are thriving while others go extinct; and none of this appears to be from natural causes, like the sun increasing its activity; and all of this is happening at rates unknown in the paleoclimate record and will most certainly have some fairly serious economic and social impacts, despite Lomborg's assurance that it's all Ok. I for one think we should reduce the use of and stop using fossil fuels. Hopefully Paris will provide a political framework, but I don't have too much faith that it will happen.
It is time to expose the political nature of the climate deniers arguments and have them justify their position scientifically and economically rather than climate scientists having to defend themselves all the time from their mostly scientifically (and economically) inane arguments. Perhaps, then there will be proper scientific debates and research centres like Lomberg's government funded centre will become a centre for serious scientific (and economic) discussion rather than some sophisticated marketing exercise. I tend to suspect that Lomberg's centre will only attract like minded people and not be truly representive of the greater climate change debate.
