Skeptical Science New Research for Week #39, 2021
Posted on 30 September 2021 by Doug Bostrom
Mann maps future inquiry from past findings
Paleoclimate and especially retrievable records of paleoclimate in the form of proxies represent a grand opportunity left us by chance. Over the course of eons Earth's climate has wandered or not so infrequently been bent and battered into various extremes. As climate influences appear then persist or fade and even vanish over the course of time they mix with other often ephemeral factors, those in their own turn on various trajectories.
As part of the geophysical hubbub of Earh's climate records of various kinds and at various scales are created, not least by biological activity. All climate events and the paleorecords they leave behind are grand experiments on a scale we'd prefer not to dabble in, commemorated by contemporaneous "lab notes" written into the record. We end up with valuble signals that while recorded in arcane languages are available for us to read, if we only we know to look, and how.
Because the mechanisms affecting climate are differentiated in their causes and effects, given enough meticulous attention and serious effort more or less individual signatures of particular climate forcings are recoverable from what superficially appears to be an unpromising jumble but actually "only" needs careful collation.
By these means we can examine the effects of particular variables of climate forcing. In particular we can see what happens when the climate is "kicked," how it "wobbles," how quickly it finds equilibrium after a shock and how that settling point may be offset from priors. This can be precious information in the context of the climate predicament we've created.
There's arguably no person better qualified than Professor Michael Mann to produce a snapshot of where we stand with learning how to ask questions of paleoclimate data, what we've been answered so far, and what to ask next. Dr. Mann brings us up to speed on the former two items and then provides advice on where we might go next, in Beyond the hockey stick: Climate lessons from the Common Era. More specifically, Prof. Mann points out how much we have yet to learn about "dynamical mechanisms and responses" or what many of us might call "how does it wiggle if we hit it with a hammer?" Here we're not talking about a bowl of gelatin but rather Earth and major system components of Earth's climate. Paleoclimate records probably have a lot to say about this if only we know the language and can see it.
This paper's synopses of dynamic components involved with climate and leading to directions to take for further research are distinguished by lucidity of exposition and a juicy collection of references, the latter always a bonus. Dr. Mann walks us through features of Earth's climate system amenable to illumination via paleoclimate data, concluding with some refreshingly circumspect discussion of the ultimate power of paleoclimate research to help our understanding. Open access, free to read, easy to read.
Housekeeping: Why the author count?
A few weeks ago New Research began featuring a "contributing author" statistic. This number reflects the total number of coauthors contributing to a given week's collection of papers. A natural question is why this should be important.
There is a general assumption in the scientific communications community that when we say "peer-reviewed academic research," all readers will automatically snap off a salute, but why should members of the general public not obsessed with research publications understand the significant differences between academic publishing and more popular fare? What happens if we assume wrongly on this account? The objectives of publishing systems vary widely and commensurately so do means and methods but this is not necessarily understood by a reader.
A distinguishing feature of academic research publications is their inherently collaborative nature, and the breadth and depth of any given article's underpinnings. To disagree with an article in the Journal of Geophysical Research is not the same thing qualitatively or quantitatively as disagreeing with a review of an automobile published in Car and Driver. There's nothing "wrong" about either publication mode and objective but there's a vast gulf between the two. What happens when folks don't grasp this distinction?
Where can misunderstandings about research publications lead us? As it happens, the author of this week's featured article perhaps offers a case in point about failure to appreciate the gravity of hasty, ill-prepared disagreement with a fundamentally robust system of investigation and disclosure.
A lot of people are researching Earth's climate but few of these workers are familiar to many of us. Delve into domains such as paleoclimate and public familiarity dips very low indeed. Professor Michael Mann is more likely to ring a bell, and as it happens his beat is principally paleoclimate, with roots in dendrochronology. About 23 years ago Mann, Hughes and Bradley published "Global-scale temperature patterns and climate forcing over the past six centuries." Based on the best information at the time, "MBH98" data visualizations produced a searing climate change communication optic in the form of what became known as the "Hockey Stick" graph. The graph was an inevitability in the face of the data at hand yet took on a life of its own, as what can be fairly termed an explosive revelation. This intentionally dispassionate assessment and conveyance of data captivated emotions in all sorts of ways and in various quarters, and given Mann's particular context of lead author in a country and world actively at war with itself over climate matters, it's safe to say that Mann's prominence in the public eye ascended.
The dust still has not fully settled on the extensive broken furniture resulting from Mann et al's discovery in 1998, but while scarred by mistreatment Mann, Bradley and Hughes remain unscathed in the fundamental matter at hand: the validity of their original finding. Indeed as Mann points out in our highighted article, the original hockey stick is "longer and sturdier," replicated, refined and extended in a plethora of subsequent investigations finding the same basic signal recording in numerous paleorecords. It turns out that a small, energetic but crucially uninformed rabble of carpetbaggers, lawyers and politicians have no effective means to discredit the devestating graph that transfixed the public's attention and hence their own. Why is the subject of attack so durably high on the Mohs scale of hard findings? Not least because it was built very on solid foundations, leading us back to "why author numbers?"
Global-scale temperature patterns and climate forcing over the past six centuries derived direct support in 50 previously published works authored by 107 contributors. Those papers in turn have their own similar provenance, are bricks found worthy and added to a wall. Attempting to construct a logical, coherent and especially superior argument from a position of ignorance against such heft and bulk of genuine expertise seated in a tightly constructed monolith of consistency and successful description and explanation is a fool's errand, as the multi-tool jack-of-all-trades Ken Cuccinelli discovered. Similarly, dismissing Mann's latest work above as pointless would mean ignoring the inexorable research path of some 437 authors contributing to the 78 works cited by Mann in his review.
Our point with author counts is that unsupported argument with scientific publications is not a fair fight in the numeric sense. It's never "I'm arguing with this author." It's always "I'm arguing with hundreds,or thousands." There's no room for a solo act here; the inherent asymmetry of the fight lies in disproportionately huge numbers of "opponents." Author counts add up to statistical reliability; gambling against a large crowd of experts while holding a thin or empty hand will lose. But we may not even see this disparity and hence be able to understand its implications unless we're shown.

Obtaining articles wihout journal subscriptions
We know it's frustrating that many articles we cite here are not free to read. One-off paid access fees are generally astronomically priced, suitable for such as "On a Heuristic Point of View Concerning the Production and Transformation of Light" but not as a gamble on unknowns. With a median world income of US$ 9,373, for most of us US$ 42 is significant money to wager on an article's relevance and importance.
- Here's an excellent collection of tips and techniques for obtaining articles, legally.
- Unpaywall offers a browser extension for Chrome and Firefox that automatically indicates when an article is freely accessible and provides immediate access without further trouble. Unpaywall is also unscammy, works well, is itself offered free to use. The organizers (a legitimate nonprofit) report about a 50% success rate
- The weekly New Research catch is checked against the Unpaywall database with accessible items being flagged. Especially for just-published articles this mechansim may fail. If you're interested in an article title and it is not listed here as "open access," be sure to check the link anyway.
How is New Research assembled?
Most articles appearing here are found via RSS feeds from journal publishers, filtered by search terms to produce raw output for assessment of relevance.
Relevant articles are then queried against the Unpaywall database, to identify open access articles and expose useful metadata for articles appearing in the database.
The objective of New Research isn't to cast a tinge on scientific results, to color readers' impressions. Hence candidate articles are assessed via two metrics only:
- Was an article deemed of sufficient merit by a team of journal editors and peer reviewers? The fact of journal RSS output assigns a "yes" to this automatically.
- Is an article relevant to the topic of anthropogenic climate change? Due to filter overlap with other publication topics of inquiry, of a typical week's 550 or so input articles about 1/4 of RSS output makes the cut.
A few journals offer public access to "preprint" versions of articles for which the review process is not yet complete. As it is the journal's decision to do so, we respect that and include such items in New Research. These are flagged as "preprint."
The section "Informed opinion, nudges & major initiatives" includes some items that are not scientific research per se but fall instead into the category of "perspectives," observations of implications of research findings, areas needing attention, etc.
What does "(provisional link)" mean?
When the input list for New Research is processed, some articles do not produce a result from the journal databases we employ. Usually this is because the publisher has not yet supplied information to doi.org for the given article. In these cases and in order to still include timely listing of articles, we employ an alternate search tactic. While this method is usually correct, sometimes the link shown will lead to an incorrect destination (available time does not always permit manual checking of these). We invite readers to submit corrections in comments below.
Each edition of New Research is reprocessed some two weeks after intitial publication to catch stragglers into the DOI ecosystem. Many "provisional links" will end up being corrected as part of this process.

its great to see Mann fighting back agains the skeptics. As the article notes above, there are now 70+ studies validating his findings. It would be great to have all the individual proxies published in a format so that everyone could easily see the underlying data that supports the findings. Everyone could easily see the long term proxies and the short term proxies used on the studies such as Pages2k, et al. While such a display would not dispel the hard core skeptics, it would certainly inspire confidence in those that are agnostic and relegate the hard core skeptics to the fringe.

Not sure if this is what you are suggesting but Carbon Brief has a neat interactive, and a good article, about proxies: Mapped: How ‘proxy’ data reveals the climate of the Earth’s distant past
David thanks for the link. Unfortunately, the format is very difficult / burdansome to navigate . I also did not see any conversion to temps from each proxy. Do you have a link to where the individual proxy data is converted into temperature graphs somewhat similar to the graphs the HS despicts. thanks
