       Satellites show no warming in the troposphere
       

       Thank you, Michael. I know that the people at UAH have had a lot of trouble, and have a history of unreliable calculations, as this article shows. I suspect the contrarian crowd are about to seize on the latest UAH numbers, and I’m hoping to have some responses I can give.

       Spencer's post does not link to any peer reviewed paper.  Will they submit it for review?  The blog post is written in the style of a scientific paper.  I wonder if they have allowed anyone to look over their new mothods to find errors or if they will wait for others to find them later.  In the past other scientists have found major errors in UAH data processing.  Most of those errors have caused the trend to be falsely low.

       The surface record does not have a history of making major adjustments to the data like the atmosphere data do.  It is more reliable.

       You cannot make statements like that, which is completely against any published science, without at least citing a source for the comment. If you found this erroneous statement (and I'm certain it wasn't in any science paper) then at least let us know where you are getting your information from.

       UAH has apparently completed a reivew of their methods and data, and re-written their software. Their new calculations seem to indicate a lower warming trend than they had been reporting. I don't know enough math or physics to make sense of their recent claims. Can someone comment?

       Over the past few days, I have been posting links to articles about the Pope's initiatives on the SkS Facebook page. This week's News Roundup will also include a number of articles on this topic.

       Dr. Judith Curry has posted some thoughts on this subject at her blog if anyone is looking for a few laughs.

       I won't post a link, those who follow the propaganda from 'that' side of the argument will know where to look.

       Heartland takes climate foolishness to a Biblical level
       

       I suggest firmly supporting your neck and head before reading on...

       I will not dignify this with a link, but it is from the Heartland website and googling all or part of the quote will show that is true.

       ...The Vatican workshop is already being presented by the liberal media as an endorsement by the Catholic Church of policies that are profoundly anti-poor and anti-life. ...

       Good Stewardship

       Most people agree that safeguarding creation – and being a good steward of the environment – is a high moral obligation. If human activity posed a genuine threat to the world’s climate, then some action would be appropriate. But global warming alarmists wave off any evidence that the threat is small or even nonexistent, and they call for policies that would shut down virtually all economic activity around the world. These unnecessary policies would cause the suffering and even death of billions of people. All people of faith should rise up in opposition to such policies.

       Certain persons currently scheduled to speak at the workshop, including UN General Secretary Ban Ki Moon and Jeffrey Sachs, director of the United Nations Sustainable Development Solutions Network, are outspoken advocates of the man-made global warming hypothesis. They and other climate alarmists have misrepresented the facts, concocted false data, and tried to shut down a reasonable, scientific debate on the issue of climate change. This conduct violates the Eighth Commandment: “You shall not bear false witness against your neighbor.”...

       Lecturing the Pope on the eighth commandment while breaking it to bits!!! Gotta say they have some lot of hutzpah! Actually something tells me they googled "what is the Catholic Church against" and just worked in every catch phrase they could into a word salad. It certainly doesn't display the depth of scholarship I'd expect from, say, a Jesuit-trained writer.

       There is an opinion piece in today's (April 29th) Australian on Lomborg's appointment, that spends some time on h-factors.  The writer seems less enamoured of them than some who have so lucidly  commented here.  Perhaps posters here will write a comment to the Australian on this opinion piece as it will reach a very wide audience.   As commenters here have a very different perspective from that of the journalist, this will add significantly to the understanding of the general public about this somewhat arcane issue.

       I was looking here for arctic sea ice data...

       But that Neven site said some new near-real-time ice thickness maps had just recently been made available from here.

       So I guess we'll be talking about 3 metre ice thickness a fair bit from now on... I mean, the trajectory of the 2015 Arctic sea ice as of April 27 looks somewhat interesting. [/understatement mode]

       Multi-year ice: I saw something today somewhere on multiyear-ice from 2000- 2009 that looked frightening but is there information on multi-year ice after this? (In the Arctic that is of course!!)

       My view on this matter have more holistic basis, a basis that applies to more than just the matter of excess CO2. It is in line with, but slightly different from, many of the comments made.

       - Many religious people understand the problem of excess CO2 production by human activity. They consider it to be another unacceptable result of the socioeconomic system that encourages people to pursue their desires regardless of the ability to understand the unacceptability of pursuing those desires. And many non-religious people share that 'worldview' and pursue advancement of civil society and humanity being a part of the robust diversity of life on this amazing planet.

       - The desire for freedom to get away with unacceptable pursuits is a 'collective view' encouraged by mass-marketing mass-consumerism. And that collective of like-minded people often politically pairs itself with the collective of people who want to get away with restricting the freedoms of others, unjustly persecuting them if they behave in ways that do no harm other than disturbing the unjustified but firmly believed values of those who selectively interpret religious texts to suit their interests. Both collectives share the desire to get away with actions that can be understood to have no real future, are meant for the enjoyment of the members of the collective to the detriment of others.

       - People's desires, not just their feelings, can strongly motivate their investigation into, and way of thinking about, an issue. A scientist that allows their personal desires to influence their work will not be as successful as they could be. A person in the global community can, at least temporarily, enjoy more success in satisfying their desires if they deliberately dismiss or discredit any better understanding that is contrary to their interests as long as hey can get away with the unacceptable things they want to get away with. And those people will fight to protect their 'freedom to do what they please' (even fighting against methods of catching them breaking driving rules). The success of such people is what needs to be stopped. And that can be accomplished by pointing out the unacceptability of their desired pursuits, but like an addict, a person locked into a damaging cycle of behaviour, you have to get them to admit that what they desire is indeed unacceptable. Until they take that first step there can be little success made by attempts to change their minds.

       - And like any other harmful addiction, the real problem is the motivations for a person to fall into the addiction. The real trouble-makers are the ones who deliberately tempt people into the damaging addiction. This can be seen to be what is going on regarding the matter of the production of excess CO2. It is a very desireable thing that many people have developed a massive damaging addiction to. And it is not a national issue. The addiction is a significant part of the global economy with varying degrees of addiction in all nations.

       Which leads back to the root problem. The power of misleading marketing, which itself is a field of science. I learned about it in my MBA training. And we were advised by our Professor that the temporary success of misleading marketing can be very tempting, but can not be expected to last. That makes it an appealing action to promote a 'dud' movie to maximize the revenue before improved public awareness from people who actually see the movie spreads. That is also what makes it appealing in politics where the effect only has to last through the time of an actual election. Of course after a series of successes through deliberately misleading marketing the success will fade, but a decade or two of such unacceptable success is all that some poeple want to get away with. Some are even pleased to get away with one political win that gives them 4 to 5 years of ability to get away with damaging unjustifiable actions.

       At times I begin to think that the business of pondering the basis of denialism is a waste of time - in the end I find myself coming to the inescapable conclusion that it is just a matter of stupidity - in the end when lives or livelyhoods are threatened then neuronal processes begin to reflect on reality.  Note contrite parents of disabled (or worse) kids who werent immunized.  Also note that there is a surprising lack of gw denialism amongst local authories on the coast or within insurance companies or small oceanic states.

       Bozzza,

       Arctic sea ice is hard to predict.  Current sea ice area is near record low.  Most observers feel that April sea ice area is not predictive of September sea ice area.  Last year there was one group that seemed to have a good model that predicted September sea ice area at the end of May, based on the number of melt ponds.  Check back at the start of June and there might be better information.  You should look at Neven's Arctic Sea Ice Blog for updates and discussion

       Does anyone know why Cryosphere Today stopped updating April 12?

       bozzza @48

       Trolling is personally attacking someone with abuse and threats on twitter and in emails where the comments made have absolutely no relationship with the debate being discussed. Also, trolling occurs because the people doing it do not like an opposing argument related to the issue being discussed. It is often done by politically motivated types or just for mischievous purposes. It is designed to drive people involved in legitimate discussion making legitimate points from the debate. The simplest way of dealing with a troll is to block them but quite often people have had to close their online accounts and stop making comments. Trolling is just another strategy to confuse and obstruct a legitimate debate.

       Ian Forrester @31, et al 32 to 25, Thumbs up. Thanks for the comments. Sorry if I drift, and not to attack the man here, but, Ian illustrates the point well; there was no consideration of the alternative argument offered. (Shrinking continents/globe was the precursor explanation for mountain building)

       If Lomborg's Present Value, and other arguments are faulty, they need to be addressed; the future of humanity may rest not just on the most precise technical understanding of the science, but the practical politically actionable business of successful action. That means money and political will.

       To attain good results we need good science, good communication, and good strategies. And yes, Lomborg may not be aware of his motivations anymore than those who get upset at my lack of scientific acumen and jump to the conclusion that it makes me wrong. The point of the article is to consider Lomborg's value, and the discussion is stuck on indices and technicalities, unable to broaden the perspective. This may be scientifically defencible, but may be missing the point.

       Finally, JH: I thought you all would know that earth flux is 44 TW and insolation is 174,000 TW, my shorthand sumo-illustration was too cryptic, sorry.

       Hi.

       My first post here. I have been fighting the good fight on YouTube comments. This article fits very well with what I have expeirenced there. I always figured I would not convince the person I was arguing with but hoping to sway lurkers who might be open to the facts.

       Besides religion, I think the hardest nut to crack is the conspiracy aspect. Those who are scared to death that Climate change is an excuse for the UN to step in and take their property and force them into some kind of ghetto. If they talk of Agenda 21, it seems like game over.

       DSL@5 Agreed.  I was going to say that many deniers have been taught that climate denial is 'of a piece' with their entire Spiritual viewpoint.  Appearing to attack elements of that viewpoint, rather than restricting oneself to the matter of AGW, reinforces the paranoic vision they've been spoonfed.  If someone imagines that accepting your arguments will land them in h_ll, you will not prevail.  On the contrary, if your evidence matches what they see outside the door each day, and also what certain Spiritual leaders, like the Pope, are saying, the chances for success are higher.

30023. Tom Curtis at 10:01 AM on 28 April 2015
       Lomborg: a detailed citation analysis
       

       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.

       Inoculating against science denial
       

       @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.

       WheelsOC

       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:

       Robert Gibbons h index = 42

       C Camerer h index = 94

       So exactly was your point?

30030. ryland at 08:17 AM on 28 April 2015
       Lomborg: 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 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).

       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.

       Lomborg: 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

       Inoculating against science denial
       

       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.

       Lomborg: a detailed citation analysis
       

       ...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?

       Inoculating 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?

       The very basis of science is questioning belief, but we can't have little Johnny going home from school unsure about the existence of god, his parents won't accept even the hint of such a thing. Science and religion are opposites and shouldn't be able to coexist within a sane mind.

       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.

       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.

       There'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.

       Lomborg: a detailed citation analysis
       

       WheelsOC @29

       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.
