The Brookings Institute finds an upsurge in acceptance of AGW among US Independents Brookings Institute Poll Perhaps someone at Skeptical Science might comment on this poll as it finds that most people's opinions of AGW are shaped by the weather they experienced in the medium-to-recent past, rather than by scientific findings.

KR at 07:17 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9 - To clarify my point a bit: Your posts here have been in essence a set of Tu Quoque (You too) fallacies. There is no evidence whatsoever that any significant amounts of bad science is being published supporting AGW - you have certainly presented none at all. Your initial statements here are quite simply bogus. -
KR at 07:05 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9 - The set of "pal-review" papers discussed in the OP are scientific failures based on those objective criteria, at a level approaching 100%. Mann et al and other papers discussed in Montford's book are not - the work in those publications has been replicated, confirmed, and extended, leading to further investigation and information - again, at a level approaching 100%. Mann's early work regarding paleoclimate temperature reconstruction (the core of the Montford book) has been validated over and over in multiple studies. That's a clear distinction - one group of works is reasonable science, the other, as sheparded through publication, is not. Montford's book is merely polemic, and inaccurate at that. Your arguments otherwise, and your apparent lack of concern regarding objective criteria, are simply not supportable. -
Rufus9 at 06:14 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
(snip) I have seen a similar influence network as figure 1 along with similar allegations in Montford's book. That may be viewed as low trust in this group for legitimate reasons. KR - you have provided some of the trigger criteria. The equation could say Trust or Accuracy. It depends on what exactly a paper is measuring and whether it is possible to reach a definitive answer. The effect of AGW on hurricanes is likely to require more latitude. As such, there could be differences in whether answering "no" to one of your questions is fatal or not. For example, it is possible to have results not consistent with other evidence. Separately, I have looked at the spreadsheet. It appears there is a slight error in the calculation of the average days to review and differences between the summary at the bottom Row 750. I believe the intention was to calculate the average for the bolded rows, not select the ranges that are in the formula. As such, if you do so, these are the results: Other = 266 days Pals = 186 days If we look at the median review, it is 146 days across the Freitas population. If you take all papers and sort numerically by Days, you visually see no obvious pattern. As such, the Significant? question appears to be "no".Moderator Response: [DB] Inflammatory tone snipped. -
KR at 04:56 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9 - Your 'trust' issues are red herrings, really. Science is about results, repeatable results. Peer review is simply a first-pass filter which, as discussed in the opening post, can be subverted - and interestingly enough, in the only case on this scale I am aware of, was subverted by folks who decry 'pal review' most loudly. Once published, the more stringent review begins - does the work contain anything new (if not, it will likely be ignored)? Are the results repeatable (not by 'audit', or code inspection, but by others investigating along the same lines)? Are the results consistent with other evidence? Do they open up new lines of investigation? The various 'pal review' papers discussed in the OP all failed one or more of these criteria, and hence are not good science. Not because of 'trust', but because they failed in the real world of objective criteria. That does not mean that they are ignored - they have instead been used as argumentative 'talking points' by those either not aware of or not caring about their shortcomings. Science is about objective results. Those, like the well-connected group discussed above, who appear to be sliding bad work through as rhetorical talking points, are not helping matters. From your post:"I put this article as: Imitation is the ultimate flattery. Essentially, this influence network has been described on both sides of this debate..."
You have provided zero support for this assertion, no evidence whatsoever. You have therefore (IMO) not demonstrated any regard for objective truth. -

Rufus9 I have written a peer-reviewed journal paper on the cause of the observed increase in atmospheric CO2 (as you will know from reading the SkS post I mentioned). Do you trust me when it comes to this particular issue? If not, why not, and what specifically would it take for you to trust my paper (above the fact that it was peer reviewed)? -
Utahn at 03:56 AM on 15 June 2012Scientific literacy and polarization on climate change
"In reality, our target audience is that large group of people who are not yet committed or engaged." Or perhaps who are not at the "poles" of the political spectrum? The Kahan study lumped people into two groups based on their Hierarchy-Egalitarian and Individualism-Communitarianism axes. What would be really interesting would've been to divvy the group up into quartiles for example, to see if scientific literacy correlated differently with the understanding in "the middle" of the political spectrum...In fact I'm sure they could've done that though I dont' see it on glancing through the paper. Maybe time for an email! -
Dikran Marsupial at 03:31 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9 I give up, the point I am making is that at the end of the day you if you are unwilling to accept the findings of mainstream science (on pretty much any area of science) then need to make an effort to investigate the science and find out for yourself. This is something you appear to be completely unwilling to do and want someone to create an automatic system for ensuring that all scientific findings are solid and trustworthy. However this is completely unrealistic. If it were possible, we would have put it into practice already. The skeptics like to talk about "trust" and "pal review" because often they don't want to talk about the validity of the science itself. Sadly this is the impression that you are giving (intended as helpful advice on the assumption that this is not what you intend). (snip)Moderator Response:[DB] As noted, the interjection of the field of medical research by Rufus9 constitutes a strawman argument, as it is not a valid comp. As such, responses to it are a waste of time.

Dikran Marsupial at 02:50 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9 There is an important point that you don't appear to understand. In science, all that matters is whether an argument is valid and supported by the evidence. It isn't about trust. It especially isn't about gaining the trust of the general public. It is fine to be skeptical about some finding, but the solution is to take the time to find out whether it is supportable or not. Peer review is only to be relied on as a basic sanity check. Expecting it to be proof of validity (trustworthyness) is completely unralistic. That is why we have scientists who have expertise to discern whether some new idea is good and worth investigating further or not. Peer review is only the start of the test of a paper, not the end. Ultimately whether a paper is any good or not is indicated by whether other scientists are convinced by it, take it up and work on it further. So if you want a better indication of trustworthyness, look at the number of citations. -

Rufus9 at 02:32 AM on 15 June 2012Pal Review - the True Story and the Fairy Tale
Trust is an important issue. It is made up of several factors that can be positive or negative: +/- expertise of the individuals involved +/- methodology / measurement error +/- reputation of the journal +/- the editors influence +/- the peer review process +/- other factors This paper raises the issue of "pal review", which is a combination of the editor and the peer reviewers. Certainly, if we see a set of "connections" between the author, editor, and peer reviewers, we might have cause for lower trust. We could also have cause for higher trust, depending on the individuals involved. What we need when we see an "event" like this is a set of criteria that move the situation to an "incident" (Dikram called it an incident in XX). So, for example, we might list several criteria that we consistently use in making this evaluation. I'm used to calling these criteria "triggers" Event Trigger 1? Trigger 2? Trigger 3? If one or all of the triggers fire, then we have an Incident. From this position, we again need criteria, especially if we are going to investigate the situation and then try to determine the Impact. Event -> Triggers -> Incident -> Triggers -> Investigate -> Triggers -> Impact What I see in this story is that we have moved from Event (correlation) to Impact ("... no doubt thanks to the false media balance which gives the ~3% minority of experts who think humans aren't the dominant cause of the current climate change (and their non-expert surrogates"). In my view, that is a leap beyond where the data supports the assertion. This seems to suffer from the ice cubes to puddle of water logic. It is easy to see ice cubes will lead to a puddle of water. However, if you have a puddle of water (e.g., the public survey results), it is much harder to work backwards to the ice cubes. It would be relatively easy to list 100 factors that could influence the survey results other than this set of authors and their papers. That is why I asked / suggested that additional steps could be taken to outline the approach we should take when we have suspicions or trust issues. Having a pre-set framework with tested criteria would presumably be helpful in sorting out whether Pal Review or other events are or are not a trust issue. As to whether there are other models, there is the Cochrane Collaboration, which is not performing the same function, but seems as though a system like this could put additional rigor in the system. Perhaps something like this exists in climate change. I have not come across it. http://www.cochrane.org/cochrane-reviews -

Rufus9 I would be more keen to continue the discussion if you were to show that you actually are interested in the answers to the points you raise. For example by either accepting that man is reposnible for the rise in CO2 or by defending your objection on the appropriate thread. Raising points and walking away from them is not acceptable behaviour in a scientific discussion. -
eostrom at 00:20 AM on 15 June 2012Greenhouse gases are responsible for warming, not the sun

DSL at 23:13 PM on 14 June 2012Pal Review - the True Story and the Fairy Tale
Has anyone tried the higher power review? Yesterday afternoon I tried putting Shakun et al. (2012) on the altar of my local church, and a beam of light shown down upon it. I tried the same thing last night with Lacis et al. (2010) and there was darkness. I am now composing emails to Lacis that will accuse him and his fellow fraudsters of fraud. Seriously, Rufus, what's the real problem here? Peer review is peer review. The method is not inherently corrupt, except where it requires people. People are the problem. They have all sorts of issues. Some are willing to treat their integrity as a commodity. Some just can't accept being wrong. Some want fame and glory, at least from their local acolytes. The sciences that make up climate science are not the grand repository for these folk. They're everywhere. They're in politics, organized religion, business, education, etc. Perhaps the fact that science overtly requires an individual to cast aside those sources of irrationality allows everyone to be more critical of failures to do so. It's hard to hide deliberate BS in science. It's possible, but very difficult. If it doesn't describe observed reality, someone will eventually start asking questions. If it's a highly scrutinized area, "eventually" could be on the order of a few days. Rufus, if you have trust issues, but you accept the general epistemology of science, then spend the time to do the math yourself. If it takes a few years, so what? The value of knowing the levels of honesty of others is more than enough compensation for the effort. -

Dikran Marsupial at 18:38 PM on 14 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9 wrote "However, how many assumptions are buried in each of those terms?", this comment pretty much makes my point. If you had taken the time to understand the argument presented in my article you would know the answer to this question already (two of the terms we can measure directly, and nowhere in the argument do we assume anything about the other two - not even their numeric values). If you really want to demonstrate true skepticism, then ask questions on the appropriate thread. As to your post in 44, what makes you think a next step is necessary after this study? The whole point is that "skeptics" complain of pal review, yet offer no real evidence to substantiate this other than the rejection of their papers (which could potentially be explained by the possibility that their papers may be flawed and hence correctly rejected - if you are attacking mainstream science that is very likely). However it is very easy to find a clear example of pal review in the skeptic community, yet they never seem to mention that, which shows a lack of balance. There is no real evidence that pal review is a significant problem in peer review, there will be the occasional incident (such as this) just as there are occasional incidents of plagiarism or scientific fraud. This is because scientists are human beings with human frailties, just like in any other sphere of human activity. A better criticism of peer review is that many bad papers have made it through peer review, even though competent reviewers ought to have spotted them (e.g. Douglass et al, Essenhigh, ...). However those who understand the purpose of peer review know it cannot be relied upon to detect every error in every paper, so even that is not a substantive issue. So I challenge you again to suggest a system better than peer review, that has not already been shown to be even more flawed. -
Rufus9 at 15:09 PM on 14 June 2012Pal Review - the True Story and the Fairy Tale
My question is whether there is a next step after this study. It has been demonstrated that their is a potential influence or conflict, but it has not been shown what impact may have occurred. My suggestion is along the lines of the following: Document the hypothesis and develop criteria to test whether there has been an impact. Conduct a review of the "pal" papers Also randomly select and review a reasonable sample of non-pal papers Present the results -
Bob Lacatena at 13:41 PM on 14 June 2012Pal Review - the True Story and the Fairy Tale
Deniers keep complaining that peer-review is broken without (a) providing evidence that it is or (b) explaining why it was never a problem until climate science warned them that fossil fuels create a serious danger to economies, civilization and our current lifestyle. To this point the only evidence that peer-review is broken comes from the way deniers (denial scientists and denial editors alike) have been able to manipulate the system. Deniers began to point to issues in other aspects of science, such as drug studies, only when it became convenient as a tactic for further assaults on climate science. And yet I don't really see them taking other branches of science to task for it. It's as if abuse of the system in drug studies and medicine is only relevant in that it demonstrates who corrupt and evil those conniving climate scientists can be. Why is that? -
Composer99 at 13:28 PM on 14 June 2012Pal Review - the True Story and the Fairy Tale
Rufus9: Having read through your comments on this thread, I fail to see how what you are arguing pertains to the OP. It appears to me that you are attempting to argue two things. If these are not reasonable summaries of your claims please clarify. (1) On account of documented issues in peer-review and retraction of papers, the conclusions of mainstream climatology must be considered far more provisional than they generally are. (2) In addition, the Earth climate is just so, well, complicated and doesn't that make for (more) uncertainty about the conclusions of mainstream climatology? Frankly, as far as I have seen you have not managed to substantiate either argument with direct evidence. In addition, argument (2) is off-topic for this thread. Meandering forays quoting Hayek or discussing medical science are certainly not going to do the job. Bringing up the latter almost certainly qualifies as a category error since the mainstream conclusions of climatology depend on our knowledge of the radiative properties of a handful of atmospheric gases, which as individual molecules or as aggregates are vastly simpler than any living organism. -

Certainly, this "pal study" is not complex, but even so, it is the equivalent of an observational study (as I said before). Sometimes, observational studies are useful.

scaddenp at 11:47 AM on 14 June 2012Glaciers are growing
In the very few places in the world where glaciers are advancing (or have some oscillation), then for most it is due to more precipitation in the neve overwhelming the increasing temperatures at the terminus (which by definition is where temperatures are too hot for ice to persist unless its terminating into water). The ones I know about are in NZ Alps and southern Andes where warmer oceans are increasing precipitation from westerlies blowing onto the mountains. With precipitation, temperature and flow rate monitored, you can model the effects of changing terminus temperature and changing snowfall. Will it last? Will if the amount of radiation warming the surface increases, then yes it will. With increasing GHG concentrations, then that is a measurable increase. For it not to continue in face of increasing emissions, then you must have either less sunlight entering or more sunlight reflected (higher albedo or more aerosols). The sun going into really deep minimum would cive us a reprieve but if we didnt use that time to reduce GHG concentrations, then we would suffer badly when the minimum was over. -
Henry justice at 11:29 AM on 14 June 2012Glaciers are growing
scaddenp at 34: Thanks, you have restored my confidence. Yes, I seem to remember that. But I thought that the terminus ice not being compacted melts much faster. My take on glaciers is that of a hard tongue of ice where temperatures may be 50-80 or more degrees F below freezing: i.e. Greenland and Antarctica, the bulk of the world's frozen water. The temps, density and melt rate of snout ice glaciers are all different. Rapid retreat is expected in "shallow iced" glacial areas (i.e.compared to Greenland or Antart.) So, yes, climate is changing for now and the glaciers clearly indicate this. But will this trend last into the upcoming decades? Anyway, I will make an effort to shake off the fairy dust. Thanks. -
Henry justice at 11:04 AM on 14 June 2012Glaciers are growing
DSL at 33: Yes, I do agree. However, come lately, the glaciers, via mass balance analysis, are disappearing at an alarming rate due to increasing air temps, lack of snow and shifting jet streams. Water supplies are adversely affected. While in Arequipa, Peru, I watched the 19,100 ft snow cap disappear. Water is a big problem down there and elsewhere. The mass balance analysis is now supporting the retreat of the glaciers. This is so bad in Peru that they are painting the rocks white. -

I've wondered for a long time where easterbrook got that temp curve, which he has long insisted is from the IPCC. Its been the lynchpin straw-man for all his talks on the topic during the past decade. For what it's worth, I've called him on it at his two most recent talks at the department (using most of the reasoning given in Dana's post, minus the background detail...kudos to him for digging up the source!). Neither confrontation seemed to register at all with him, though. He refused to acknowledge any of the points, that the curve in no way represents an actual "prediction" of the IPCC, that his claims 1 C prediction by the IPCC by 2011 is egregious cherry picking in any case, or that his own predictions are fairing poorly (in addition to not being based on any rigorous physical process). Case in point: all the concepts in his Heartland talk (plus some) are in his new book published by Elsevier. The latter is really a travesty because its getting presented as "peer-reviewed literature (it isnt) and b/c it was published by the "science" division at Elsevier. It's all very unfortunate. -

No, there is something seriously wrong with that if:- 99% of the debate and debating points are grossly inaccurate and manufactured.

- Those manufacturing the artificial debate are laughably unqualified to do so, and yet they are taken seriously by those who are taken in (like yourself).

So the Monckton 'Misinformation' tour pops up in yet another part of the world. I wonder how many of his adoring fans notice what an exciting life he leads and thus how unlikely it is that he would change his mind, and thus have to give that up, no matter how blatant the facts were that he was wrong. For my part, seeing as he cannot answer Peter Hadfield's points in his debate on WUWT, I suspect that he knows full well that he is wrong and is deliberately not going to put his good life at risk by being forced into admitting it. Seeing as Climate Change will harm his country, I wonder where that leaves him with the authorities seeing as he clearly does not want any action to combat it. In the U.K. had a banker who was so well respected that he was knighted, but then made one mistake and was subsequently stripped of his title. Why Monckton is still a peer is a mystery to me. Though why he was made a peer in first place is an even bigger one. We do live in the 21st century, after all and hereditary peerages should surely be a thing of the dim, distant past. -

CBDunkerson There have been some climatol0ogists making the claim that the rise in CO2 is natural, including Roy Spencer (as dana pointed out), Tom Segalstad, Richard Courtney, and now Murry Salby. The flaws in their arguments are pretty obvious, which just goes to show that scientists can have blind spots, just like the rest of us. As I said, the difference between true skepticism and stubborn bias is the willingness to investigate, rather than to simply question (questioning is only of value if you are interested in the answer). -

True skepticism involves investigating the issue to find out whether those views are reasonable, just refusing to accept them without taking the effort to look into it is merely bias. I have pointed out to you that there are good reasons supporting my view that papers purporting to show that the rise in CO2 is natural being likely to be a particularly bad, and given a link where we can discuss it. However, you have not responded to that point, which gives the impression that your apparent skepticism is actually (possibly unconscious) bias, as you do not appear to be interested in investigating the truth, merely restating your original point. As to your points (i) it has not been established that pal review is a substantive issue in peer review, other than in isolated incidents. (ii) Of course peer review has its flaws, but like the Churchill quote "It has been said that democracy is the worst form of government except all the others that have been tried", what would you replace it with that hasn't already been shown to be even more flawed (e.g. live public debate). (iii) observational studies can never prove causation (arguably it is fundamentally impossible to prove causal relationships without making assumptions) - so does that me we should ignore all observational studies? Of course not! Sure we should keep an open mind and accept there are things we don't know or are uncertain. However, it also needs to be accepted that there are things we do know with high certainty, of which I have already given an example. -

Given human variation, health care is a poor analogy to climate science, and it is a red herring in this discussion. Statistics isn't physics. Some people will die from a lifetime of smoking, some won't. One of drugs A, B, and C will work for somebody, but doctors will have to try them one at a time to see which works. This is somewhat like the disciplinary-error problem I discussed at RC. Analogies can be wrong. -

I'd say blogs and books "from both sides" of any debate arent much use. You are skeptical of peer-review, but I would say that peer-review is a necessary gate-keeper. If you are not an expert in a field, then faux experts can easily pull the wool and that goes for health care in spades. Just because its peer-reviewed doesnt make it right - but if it cant get through peer-review, then its almost certainly wrong. Sure there are plenty of latter-day Galileo's claiming persecution but for one's I've have read in fields I know, you can see why they cant get it published. Especially if publishing outside their area of expertise. Not a few are screaming because Nature or Science wont publish them - well duh - everyone suffers that. If you think someone is hard done by with a paper, then ask to see their reviewers comments. That said, I would agree with 1 and 2. -

Let me simplify my position. 1. Pal review is one more factor in a long list of known flaws / issues with the peer review system. 2. This analysis is the equivalent of observational studies in medicine - sufficient to identify a hypothesis for further research, but not proof of causation. I obviously picked the wrong quote to illustrate my skepticism of AGW. It is at a much more general level after reading books and blogs from both sides. However, I spend a lot more of my time reading and researching health and nutrition. I can comfortably say that "accepted science" - like saturated fat causes heart disease or salt is bad for you or red meat causes cancer or higher mortality are documented in hundreds of studies. Yet, through the wonder of the Internet, we have access to people like Gary Taubes who research these areas "settled science" and we find the evidence is not convincing. Politics, ego, placebos that beat drugs, drugs that kill people, omitted data, not publishing a report for 16 years because "... we didn't like the result", and many other issues are revealed. Something similar is going to happen in this debate if we give it time and have an open mind to accept that there are limits to our knowledge. And, there's nothing wrong with that. -

Tenney Naumer @4, it is from Rignot and Mouginot (2012), ie, the second article discussed. -

Thanks for the response. I admit to being slightly disingenuous in my question. I think the recent and unprecedented (at least since the late 70s) extreme volatility in oil price is directly linked to the first stages of peaking production. So I guess I'm with scaddenp more on this one - "problems with production/demand in oil will only get worse." Speculation may account for some of what's going on, but as I understand it there is evidence that speculation may actually have a stabilizing effect on oil price as we approach the peak. I guess I am just amazed at the blathering about an oil boom. I just wonder if people ever stop to think WHY there is a sudden oil boom, and WHY prices are fluctuating wildly, and WHY economic growth worldwide is sputtering. I mean, my god, look at that graph of gas prices. But I expect, just as we have done nothing to address climate change, we will do nothing to address this problem either until we are looking back at the top of the curve. Interesting times. -
scaddenp at 08:46 AM on 13 June 2012Glaciers are growing
Henry, you surely arent mistaking articles by right-wing think tanks for science? Looking at published science we note for instance here, we find temperature is the predominant influence. Modelling on the franz joseph when advancing showed it needed a 40% increase in precipitation to offset a 1 degree increase temperature at the terminus. The worldwide glacial retreat is consistent with established climate theory. All of us want to find evidence that supports what we would like to be true. The development of science has showed that we need find a discipline that protects us from this normal human reaction. Try thinking about what evidence would convince that your views are wrong and see if there is evidence to support this. Look for that evidence in peer-reviewed science publications. There is plenty of fairy-dust about on the net for those just want to be fooled.
