Skeptical Science New Research for Week #50, 2020

Posted on 16 December 2020 by Doug Bostrom

"Wait - we don't need a bigger computer?"

Readers following the "Advances in climate & climate effects modeling..." portion of the weekly research roundup may have noticed: in general, higher model resolution calculating climate behaviors at finer scales is helpful for increasing model fidelity against real-world observations. Coincident to this is another matter: It may be unfair as a purely scientific matter but climate models are held to a peculiarly high standard, given their crucial role as decision tools affecting huge swathes of human affairs. Within the error brackets of "we're in trouble" models have been good enough for quite a while, but what with the fuss and bother of modernization to account for what we're learning some folks want to make quite sure of what they're buying into, and fair enough on that. 

All of this translates to more hardware and expense, especially with the fading of "Moore's Law." Thus it comes as a welcome relief to "we need more transistors!" when we see such a finding as Jinlun Zhang's Sea ice properties in high?resolution sea ice models, where it appears to be the case that ever-finer resolution does not continue to produce results with productively higher fidelity. The abstract:

An Arctic sea ice–ocean model is run with three uniform horizontal resolutions (6, 4, and 2 km) and identical sea ice and ocean model parameterizations, including an isotropic viscous?plastic (VP) sea ice rheology, a mechanical ice strength parameterization, and an ice ridging parameterization. Driven by the same atmospheric forcing, the three model versions all produce similar spatial patterns and temporal variations of ice thickness and motion fields, resulting in almost identical magnitude and seasonal evolution of total ice volume and mean ice concentration, ice speed, and fractions of ice of various thickness categories over the Arctic Ocean. Increasing model resolution from 6 to 2 km does not significantly improve model performance when compared to NASA IceBridge ice thickness observations. This suggests that the large?scale sea ice properties of the model are insensitive to varying high resolutions within the multifloe scale (2–10 km), and it may be unnecessary to adjust model parameters constantly with increasingly high resolutions. This is also true with models within the aggregate scale (10–75 km), indicating that model parameters used at coarse resolution may be used at high or multi?scale resolution. However, even though the three versions all yield similar mean state of sea ice, they differ in representing anisotropic properties of sea ice. While they produce a basic pattern of major sea ice leads similar to satellite observations, their leads are distributed differently in space and time. Without changing model parameters and sea ice spatiotemporal variability, the 2?km resolution model tends to capture more leads than the other two models.

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$ 9,3733, for most of us US$ 42 is significant money to wager on an article's relevance and importance. 

  • 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 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.

Suggestions

Please let us know if you're aware of an article you think may be of interest for Skeptical Science research news, or if we've missed something that may be important. Send your input to Skeptical Science via our contact form.
