Mark Lynas ‘99% Consensus’ on Climate Change – Busted in Peer Review.

From email:

My name is Yonatan Dubi, I am a professor of chemistry and physics at Ben Gurion University, Israel. I am also one of Israel’s leading advocates for rational environmentalism and climate realism. Together with a few colleagues we have conducted a very nice research, detailing and quantifying the flaws in the famous consensus study by Lynas et al, which (falsely) claimed the ridiculous 99% consensus. After a year long journey, our paper was finally published in the peer reviewed journal Climate, the link is https://www.mdpi.com/2225-1154/11/11/215.

The conclusion does not follow from the data”: Israeli study trashes extreme global warming consensus claim.

Abstract

Anthropogenic activity is considered a central driver of current climate change. A recent paper, studying the consensus regarding the hypothesis that the recent increase in global temperature is predominantly human-made via the emission of greenhouse gasses (see text for reference), argued that the scientific consensus in the peer-reviewed scientific literature pertaining to this hypothesis exceeds 99%. This conclusion was reached after the authors scanned the abstracts and titles of some 3000 papers and mapped them according to their (abstract) statements regarding the above hypothesis. Here, we point out some major flaws in the methodology, analysis, and conclusions of the study. Using the data provided in the study, we show that the 99% consensus, as defined by the authors, is actually an upper limit evaluation because of the large number of “neutral” papers which were counted as pro-consensus in the paper and probably does not reflect the true situation. We further analyze these results by evaluating how so-called “skeptic” papers fit the consensus and find that biases in the literature, which were not accounted for in the aforementioned study, may place the consensus on the low side. Finally, we show that the rating method used in the study suffers from a subjective bias which is reflected in large variations between ratings of the same paper by different raters. All these lead to the conclusion that the conclusions of the study does not follow from the data.

The original study, to which the above is a response;

Greater than 99% consensus on human caused climate change in the peer-reviewed scientific literature

Abstract

While controls over the Earth’s climate system have undergone rigorous hypothesis-testing since the 1800s, questions over the scientific consensus of the role of human activities in modern climate change continue to arise in public settings. We update previous efforts to quantify the scientific consensus on climate change by searching the recent literature for papers sceptical of anthropogenic-caused global warming. From a dataset of 88125 climate-related papers published since 2012, when this question was last addressed comprehensively, we examine a randomized subset of 3000 such publications. We also use a second sample-weighted approach that was specifically biased with keywords to help identify any sceptical peer-reviewed papers in the whole dataset. We identify four sceptical papers out of the sub-set of 3000, as evidenced by abstracts that were rated as implicitly or explicitly sceptical of human-caused global warming. In our sample utilizing pre-identified sceptical keywords we found 28 papers that were implicitly or explicitly sceptical. We conclude with high statistical confidence that the scientific consensus on human-caused contemporary climate change—expressed as a proportion of the total publications—exceeds 99% in the peer reviewed scientific literature.

What a surprise – a study which claims over 99% consensus appears to be unsupported by the evidence, because neutral papers were misclassified, and skeptic papers were ignored.

Lynas, et. al., is probably the worst case of confirmation bias ever published. Of course, we all knew that when we first saw it. The Lynas paper was all about grabbing headlines, not science. Now watch the fun as Lynas et. al. tries to defend their paper, with even greater levels of nonsense.

The continued need to show a consensus ‘that the science is settled’ just shows that in reality it isn’t. And every one of these ‘consensus’ papers has been busted bigly. This is just the latest example.

Anyone who has not read that talk by Michael Crichton should do so. “Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.”. If that isn’t clear enough for you, there’s lots more in the talk.

“The only problem with your interpretation of his comment is that, regarding climate change, experiment does indeed agree with theory.”

TFN, you comment is absurd.

Paleoclimatology scientific data shows that there is no correlation of CO2 levels with “global temperature”, including periods when CO2 atmospheric levels were in the range of 4,000 to 6,000 ppm (compared to today’s level of 420 ppm). See attached graph.

Furthermore, UAH satellite date for monitoring “global temperature” (the best measurements we have a such a ridiculous single value) have demonstrated no statistical “global warming” over the last eight-plus years (ref: https://wattsupwiththat.com/2023/07/05/the-new-pause-remains-at-8-years-10-months/ ), despite total atmospheric CO2 levels increasing from about 400 ppm to 423 ppm (about a 6% increase) over that same time period

In case you are especially dense, nature is “running the experiment” for us. You may not like the “experimental” results but Feynman’s comment holds true.

This isn’t “all the data,” though, is it? It appears to be a singular reconstruction of temperatures from a single geologist using a single method (essentially using geologic evidence to binarily assign ‘warm’ or ‘cold’ to global temp) plotted against a model (uh oh) of atmospheric CO2 concentration.

Could you or anyone else in the thread expound on why this particular reconstruction is to be taken as the be-all end-all dataset that supersedes all others? It seems to be at odds with, e.g., Royer et al. 2004 and others.

AlanJ,

Assuming your comment to MarkW was made in reference to the plot of “Global Temperature and Atmospheric CO2 Over Geologic Time” that I posted in a preceding comment, I simply invite you to see at the bottom left border of that image these notes:
Temperature data after C.R. Scotese (with reference URL provided)
CO2 after R.A. Berner, 2001 (GEOCARB III)
(note: similar notes are also provided on the bottom left face of graph itself)

I think you will find that Scotese incorporated a variety of sources of scientific paleoclimatology proxies to obtain his graph of temperature over time (specifically, such was not a singular model “reconstruction”), and that Berner likewise incorporated a range of sources of scientific paleoclimatology proxies to obtain his graph of atmospheric CO2 concentration levels over time (again, specifically such not being a singular model “reconstruction”).

Also, please note the graph of global temperature over time has a numerical y-axis scale on the right side of the graph, thus falsifying your absurd statement “using geologic evidence to binarily assign ‘warm’ or ‘cold’ to global temperature.

Given the above defects in your understanding of what was presented, why should anyone attempt to reply to your sophomoric question:
“Could you or anyone else in the thread expound on why this particular reconstruction is to be taken as the be-all end-all dataset that supersedes all others?” Hint: such a statement is commonly known as a strawman argument/logical fallacy . . . look it up.

Reply to  ToldYouSo
November 1, 2023 12:15 pm

Scotese is using forms of geologic evidence such as sediment deposits to infer when the earth was in an icehouse or hothouse state, he is not providing a quantiative paleoclimate reconstruction using temperature proxies. The scale on the y-axis is extremely approximate and in divisions of 7 degrees C. It’s a very dated approach that doesn’t yield a result that can be directly compared with atmospheric CO2 models like GeoCarb.

And of course you deftly evade my question. Disappointing, but expected. If your graph is meant to represent the best available reconstruction of past climate states, then surely you must be able to articulate why it is a better representation than reconstructions that are inconsistent with it. But you can’t do that, so instead you put up a bravely patronizing facade and pretend that you aren’t answering because you’re too smart to be bothered. Typical evasion.

The IPCC AR6 has a nice graphic illustrating CO2 and temperature correspondence over the past 60 million years:

Royer, 2004, 2006 demonstrate a close coupling between temperature and CO2 across the Phanerozoic. With the caveat that the data become exponentially more uncertain the further back in time we go (a fact which is completely absent from the reconstruction you provided above).

Reply to  AlanJ
November 1, 2023 5:16 pm

Your serious, right? Or pretend to be serious in presenting this graph fronted by the IPCC? Really???

I just observe the following in the text label for the graph you presented as “data”:

1) “CO2 levels for the last 800,000 years through the mid-20th century are from air trapped in in polar ice.” and “Global maps for two paleo reference periods are based on Coupled Model Intercomparison project Phase 6 (CMIP6) and pre-CMIP6 multi-model means . . .” Again I have to ask, you got any data for time time periods prior to 800,000 years ago, considering that climate models do NOT produce data? Hint for you: the last 800,000 years ago is only 0.1% of the paleoclimatology timespan covered by the Scotese & Berner combined data graph I posted.

2) There are too many science-based websites to mention that discuss the problems of using “air trapped in polar ice” as any kind of accurate proxy for past global atmospheric CO2 concentration. More importantly, the oldest continuous ice core records extend to 130,000 years in Greenland, and 800,000 years in Antarctica . . put that in the context of discussing global paleoclimatology proxies going back some 500 million or more years . . . just laughable!

3) “CO2 concentrations from millions of years ago are reconstructed from multiple proxy records (grey dots are data from Section 2.2.3.1, Figure 2.3 shown with cubic spline fit).” Yet there is a complete absence of “grey dots” or reference to how the “correlated” (yeah, right!) temperature curve “from millions of years ago” was obtained other than perhaps the CMIP6 multi-model means stated in (1) above. Again, models do NOT produce data.

3) The Scotese & Berner graph I presented covers the last 550 million years of paleoclimatology data, whereas the IPCC-fronted graph that you presented covers only the last 60 million year of asserted climate “data”, or less than 11% of the period under discussion. Do you see any problem with that?

I asked for data, and you provide this sh*t.

Finally, yes, I do “dig in my heels” when I encounter stupidity. Piling it on does not help your cause.

Too many sites, but you can’t name any of them. Got it. And no peer reviewed papers to cite, either.

Yet there is a completeabsence of “grey dots” or reference to how the “correlated” (yeah, right!) temperature curve “from millions of years ago” was obtained other than perhaps the CMIP6 multi-model means stated in (1) above. Again, models do NOT produce data.

Well, they cite the very exact section of the report (2.2.3.1) describing the multi proxy CO2 data:

Isotopes from continental and marine sediments using improved analytical techniques and sampling resolution have reinforced the understanding of long-term changes in atmospheric CO2 during the past 450 Myr (Table 2.1 and Figure 2.3). In particular, for the last 60 Myr, sampling resolution and accuracy of the boron isotope proxy 299 Changing State of the Climate System Chapter 2 2 in ocean sediments has improved (Penman et al., 2014; Anagnostou et al., 2016, 2020; Chalk et al., 2017; Gutjahr et al., 2017; Babila et al., 2018; Dyez et al., 2018; Raitzsch et al., 2018; Sosdian et al., 2018; Henehan et al., 2019, 2020; de la Vega et al., 2020; Harper et al., 2020), the understanding of the alkenone CO2 proxy has increased (e.g., Badger et al., 2019; Stoll et al., 2019; Y. Zhang et al., 2019; Zhang et al., 2020; Rae et al., 2021) and new phytoplankton proxies have been developed and applied (e.g., Witkowski et al., 2018). Understanding of the boron isotope CO2 proxy has improved since AR5 with studies showing very good agreement between boron- CO2 estimates and co-existing ice core CO2 (Hönisch and Hemming, 2005; Foster, 2008; Henehan et al., 2013; Chalk et al., 2017; Raitzsch et al., 2018; see Figure 2.3c). Such independent validation has proven difficult to achieve with the other available CO2 proxies (e.g., Badger et al., 2019; Da et al., 2019; Stoll et al., 2019; Y. Zhang et al., 2019). Remaining uncertainties in these ocean sediment based proxies (Hollis et al., 2019) partly limit the applicability of the alkenone δ13C and boron δ11B proxies beyond the Cenozoic, although new records are emerging, for example, Jurikova et al. (2020). CO2 estimates from the terrestrial CO2 proxies, such as stomatal density in fossil plants and δ13C of palaeosol carbonates, are available for much of the last 420 Myr. Given the low sampling density, relatively large CO2 uncertainty, and high age uncertainty (relative to marine sediments) of the terrestrial proxies, preference here is given to the marine based proxies (and boron in particular) where possible.

But I guess reading is too much to ask of this crowd.

Finally, yes, I do “dig in my heels” when I encounter stupidity. Piling it on does not help your cause.

I think you’re digging in your heels in because you can’t answer the question, which you make more and more obvious with each comment.

“Too many sites, but you can’t name any of them. Got it. And no peer reviewed papers to cite, either.”

Here you go for both, since you “asked” so nicely:

“Three main CO2 and temperature relations are suggested with supporting evidence, but uncertainties and outside factors need to be taken into account. These ambiguities make it unclear whether CO2 is a forcing factor on climate . . .
Flaws in Data
In ice core analysis, researchers run into uncertainties and possible errors that obscure the recorded data. Mentioned before, the age of the trapped CO2 is found by the age of the ice it is enclosed in. There is an age difference between the age of the ice and the age of the CO2 but the difference varies by glacial period. Monnin points out . . . that the uncertainty of the age of the ice increases in older ice cores . . . In analyzing ice cores, both Monnin et al. and Indermuhle et al. report that chemical impurities in the ice need to be taken into account when measuring CO2 concentrations. High resolution Taylor Dome ice core measurements show that CO2 produced from chemical reactions between these impurities masks the actual atmospheric CO2 concentrations . . . Another flaw is noted by Veizer et al. reporting that it is unclear whether the relationships between CO2 and temperature found in ice cores reflect a global or local phenomenon. Veizer found that oxygen isotopes measured in calcite and aragonite shells show oscillations of tropical sea surface temperatures in phase with the ice core climate records from Antarctica, thus providing evidence to support the idea of climate variability as a global phenomenon. But, this data is at odds with temperature models that depend on CO2 as a forcing factor. Therefore, whether climate change is global or local depends on whether CO2 is a forcing factor on temperature. This further complicates any hypothesis taken from ice core analysis.”
https://web.mit.edu/angles2008/angles_Emmanuel_Quiroz.html
[my bold emphasis added]

and

“Ice cores from Greenland provide unique records of rapid climate
events of the past 120 kyr. However, because of relatively high concentrations of impurities, Greenlandic ice cores do not provide reliable atmospheric CO2 records. Antarctic ice cores, which contain an order-of-magnitude fewer impurities, provide reliable records, but existing data from the deglacial period from Antarctica either provide only low temporal resolution or are of relatively low precision . . .
“METHODS . . . Prior work in Greenland has demonstrated that CO2 records can be compromised through in situ production when
abundant concentrations of calcium carbonate are present. Calcium is delivered to the ice in the form of carbonate dust that blows onto the ice-sheet surface and is buried by subsequent accumulation . . . each ice core from Antarctica is both geographically unique and affected by distinct atmospheric processes that can deliver various chemical species to the sites . . .  In addition to calcium carbonate, the oxidation of organic compounds can also affect the CO2 concentration from ice cores.”

This reference is to an essay written by an undergraduate bioengineering student. And of course there are uncertainties and challenges when dealing with paleoclimate archives. Nobody doubts this. The claim you’re making is that such challenges have never been overcome, not merely that they exist. Paleoclimate scientists are well aware of potential contamination of ice core samples or myriad other uncertainties, and spend an enormous amount of time and effort ensuring that they are properly accounted for. The exact same point applies to Marcott et al. (who, incidentally, open their abstract by noting “Global climate and the concentration of atmospheric carbon dioxide (CO2) are correlated over recent glacial cycles.” Oops).

All the following blah, blah, blah that you cite is specific to CO2 and CO2 proxy data, but you missed the fact, clearly given immediately above by you quoting my comment, that I specifically was asking about the paloeclimatology temperature curve in the graph you posted, and it having an absence of any indicated data points or described derivation.

The section of the report you quoted is referring to CO2 data, so you probably should proofread your comments more carefully before hitting submit:

“CO2 concentrations from millions of years ago are reconstructed from multiple proxy records (grey dots are data from Section 2.2.3.1, Figure 2.3 shown with cubic spline fit).” Yet there is a completeabsence of “grey dots” or reference to how the “correlated” (yeah, right!) temperature curve “from millions of years ago” was obtained other than perhaps the CMIP6 multi-model means stated in (1) above. Again, models do NOT produce data.”

The caption quite clearly states that “Global surface temperature prior to 1850 is estimated from marine oxygen isotopes.” See, e.g., Zachos, 2001 for an example. You really do need to read more carefully.

And, of course, all throughout this you are still desperately avoiding actually answering my question, and are still desperately avoiding the references to Royer 2004, 2006. I expect your attempts at deflection will extend indefinitely.

I did not criticize the website for being an undergrad essay submission, I pointed it out because it is amusing – you claim there are “too many science based websites to mention” showing that ice cores are poor archives of paleo CO2 levels, yet you can only dredge up an essay written by an undergrad. An ad hominem would be to say, “the kid is wrong because he is an undergrad,” which I did not say.

The actual criticism I lodged, which you again deftly sidestepped (you’re quite good at never confronting the actual argument, aren’t you?) is that the existence of potential contamination in ice core records does not preclude the use of such records as paleo archives, and scientists are very, very well aware of the potential issues and work very hard to ensure that the results of ice core analyses are robust.

Oh, and you may once again want to make reference to Royer 2004 and 2006 in any reply.

Oh, yes, thanks for bringing it up. You did ignore it once again. Royer 2004, 2006 shows that CO2 and temperature covary across the Phanerozoic, completely demolishing what little argument you’ve actually managed to muster in this thread. But do please carry on deflecting and evading, it does seem to be the only tool in your arsenal.

Globally, we are warming in line with averaged modelled projections …

Attached is the 21st century “warming” of the GISS dataset (as good, or bad, as any other GMST reconstruction from thermometer readings) compared to the “projections” of both the CMIP5 models using RCP inputs and the CMIP6 models using SSP inputs.

Note the offsets to align everything to AR6’s “2010 = 0.99°C above the pre-industrial [ 1850-1900 average ]” level.

GISS has a definite “step”, oscillating around 0.95°C from 2002 to 2013(-ish) before quickly rising then oscillating around (or just over ?) the 1.25°C level from 2015/2016 to “now”.

The models, on the other hand, show (relatively) smoothly rising “warming” trends …

Loftily declaring that “we are warming [ present tense ] in line with averaged modelled projections” is a subjective opinion, nothing more.

Then they average them all together, and lo and behold, the results fit what they expected to happen.

The models overpredict the amount of warming, and the warming only seems to come with every El Nino not steadily with every CO2 ppm.

During the first decade of the 21st century, China and India and pretty much the rest of the developing world turned up their coal and steel plants to 11, and yet temperatures remained flat. Climate models, not so much.

Did you even think to consult the Cook, et.al, published paper to see what the specific criteria of his “study” was?

Here it is, taken verbatim from the section “Methodology” of his 2013 published article (available at https://iopscience.iop.org/article/10.1088/1748-9326/8/2/024024 ):
“We classified each abstract according to the type of research (category) and degree of endorsement. Written criteria were provided to raters for category (table 1) and level of endorsement of AGW (table 2). Explicit endorsements were divided into non-quantified (e.g., humans are contributing to global warming without quantifying the contribution) and quantified (e.g., humans are contributing more than 50% of global warming, consistent with the 2007 IPCC statement that most of the global warming since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations).
(my bold emphasis added for the benefit of responding directly to your question . . . mid-20th century would be 1950, arithmetically)

The methodology of Cook et.al. was so flawed—among other things, being restricted to “surveying” abstracts only—that it’s no wonder this publication received the scorn and criticism that it has from the science and mathematical communities, starting in 2013 and continuing up to today.

You have clearly never done any electrochemistry. I have. Conductivity water, which is stringently purified and free of dissolved games, and is kept under argon, has pH 7 by definition. Exposing it to the atmosphere even for a few seconds causes the pH to drop measurably.

It was “100 Authors against Relativity.” There were actually 121 in total and you’d be hard pressed to find even a small handful that made any contribution to science.

And, like the ‘climate scientists’ not one of them used the scientific method in the construction of their arguments, all are shaped by scientific incompetence and failed to provide any facts to support their arguments, relying on (sometimes) complex mathematical formulae. Honestly well worth looking at an analysis of the ‘100 Authors’, the parallels are quite strikung.

Not quite historically right. The luminiferous aether theory of light propagation in a vacuum was disproven by the Michelson Morley experiment in 1887.
Einstein did not publish his theory of special relativity until 1906.
The ‘100’ expert scientists disagreeing with his relativity theories was published by Nazi Germany in the mid 1930’s, because Einstein was Jewish.
To which Einstein (in Switzerland on way to US) famously replied, “Why 100? One would suffice to prove me wrong.”

If you go through the list of arguments against, you’ll find that many of them really do mention the ether as an objection, despite the earlier work disproving it. Also only about 91 or so were German, many were from other countries, including USA, and although many were published in German, one was in English and a couple more were in other languages. Yes the reason was most likely the fact that he was Jewish but, given the very widespread (and disturbingly popular) anti-Jewish sentiment across Europe and North America, it’s likely that these authors were anti-semitic rather than Nazi collaborators. Also there is no primary source for Einstein having said that last bit – it is attributed to him but there is no evidence that he ever said it.

The concept of a ‘scientific consensus’ was the first red flag for me. Back then, I was naive, much like any typical 16-year-old, but even then, I found the notion of an apparently solid consensus rather dubious. I understood that Earth’s climate is incredibly complex, which is why we can’t reliably predict the weather beyond a mere 10 days. Some argue that weather is distinct from climate, but I was puzzled by this contradictory argument. If our grasp of weather patterns is limited to just a week or so, how can we confidently make predictions for 10, 20 or even 100 years into the future? If our understanding of the natural world were as robust as it’s presented, we should be far better at long-term weather forecasting. When climate proponents present a model alongside the global surface air temperature data, and they seem to correlate exceptionally well, almost too well, it’s hard not to raise an eyebrow and wonder if there’s more to the story than meets the eye. Studies like this only bolster my skepticism, making it increasingly challenging to accept these findings at face value.

ANother point is that weather forecasts are trying to predict what the weather at a particular point at a particular time in the future is going to be.

Long range forecasts try to predict what the average climate for a region is going to be for a few weeks to a month at a time.

From what I recall, Joe didn’t predict what the temperature was going to be, just that it would be colder than average.

You are not drawing conclusions from fact. Yes I am familiar with IPCC reports. Reports aren’t facts though they may contain facts. The actual scientific reports from IPCC find no adverse changes in any important climate parameters – only a gentle warming over the past several decades. There is nothing in the reports that proves human activity is mostly responsible for that warming – that is only found in climate models which have never been validated.

They are paying to propagandize Americans into supporting Islamic terrorists, and they seem to be doing a pretty good job of it. Children are easily influenced. Those that have been fooled are marching in support of beheading jewish babies and burning them alive in ovens.

NO WARMING in the satellite record apart from at El Ninos…

As always on WUWT, there will be no critical analysis of the critical analysis, its conclusions will be accepted as indisputable fact.

Dentelski’s primary objection seems to be with the “non position” papers in Lynas et al., and Dentelski argues that an analysis of the bodies of each manuscript should be undertaken to ascertain whether the paper is truly “no position” or not. This is a fine idea, but Dentelski hasn’t done it. Claiming that “doing the study a completely different way might or might not possibly produce a slightly different result, we have no idea,” is not quite the same thing as “busting” a paper.

I have read it, very interesting reading and so completely unlike your description that it made me wonder if you’d even seen it. The paper sets out to analyse and critique the Lynas paper as a scientific study, not to compete with it on the same ground. From that limited perspective they successfully prove that Lynas’ methodology was too vaguely worded, relied on just a preliminary scan of the introduction (in this I disagree with Dentelski, et al. in that they credit Lynas with reading through all 3000 abstracts, whereas I think he used a basic word-search program instead) and then goes on to discuss the flaws in choosing the papers and with the neutral/sceptical papers. It all seems very straightforward – Lynas was far too sloppy in his methodology and analysis, so the conclusions he draws can not possibly follow from the way he analysed the papers.
Very much like your comments – vague and sloppy work that fails to support your conclusions.

AlanJ
Reply to  Richard Page

From that limited perspective they successfully prove that Lynas’ methodology was too vaguely worded, relied on just a preliminary scan of the introduction

They don’t prove this, they claim it. They suggest that a complete analysis of the text of the full manuscripts might possibly result in a different figure than the 99.8% that Lynas derives. Nowhere do they actually demonstrate that this is the case. It might well be true, or it might not be true, Dentelski makes no attempt to prove this either way. Of course it might also be true that an analysis of the full text of all the manuscripts would produce an even stronger consensus, but Dentelski never raises this as a possibility.

Dentelski are simply proposing a completely different methodology, not rebutting the methodology that Lynas uses, and they make no effort to actually demonstrate that their alternative produces materially different results. Dentelski does not show that the results do not follow from the data, but rather that some other hypothetical set of data might hypothetically produce a slightly different hypothetical result, maybe.

Reply to  AlanJ
November 1, 2023 9:24 am

They don’t need to set up a competing study doing the same work. They have conclusively shown thay Lynas’ methods were badly done, flawed, and the conclusions drawn are not supported by the data and analysis methods Lynas uses. It is up to Lynas to redo the study, correcting the flaws and tightening up the methodology, in order to produce a workable paper. That is how science works, it’s not up to other scientists to do the work that Lynas should have done in the first place, that’s just absurd.

AlanJ
Reply to  Richard Page
November 1, 2023 9:49 am

Again, they’ve shown nothing of the kind. Lynas et al. laid out their methodology and reported their results. Dentelski is claiming that a completely different methodology than that used by Lynas et al. might hypothetically produce different results, and that this invalidates Lynas et al.’s approach. Lynas et al.’s abstract rankings follow the definitions Lynas et al. lays out and are valid (i.e. it’s not shown that they’re miss-classifying abstracts based on the contents of the abstracts). Using Dentelski’s proposed “full text analysis” approach, there might be differences in the classifications of some papers, but to say that these differences in the classifications “invalidates” Lynas et al.’s results, it has to be shown that the differences in the these classifications produces materially different results. Dentelski doesn’t do this.

And, yes, it is completely up to Dentelski to do the work if he is proposing that his methodology is better and produces different results. That’s 100% on him. You generally don’t see papers published that are nothing more than a critique of an existing paper unless the new paper is substantively adding new information in addition to the critique (i.e. “we think our methodology is better and here are the results using our method”). A critique like Dentelski’s is more appropriately submitted as a letter or comment to the publisher.
