Skeptical Science New Research for Week #21, 2021

Moving targets

In Permafrost carbon feedbacks threaten global climate goals, Susan Natali & crew point out a potential serious omission in Paris Accords climate targets: the changing “nature” of permafrost and the carbon and hence readily available CO2 therein. The abstract: 

Rapid Arctic warming has intensified northern wildfires and is thawing carbon-rich permafrost. Carbon emissions from permafrost thaw and Arctic wildfires, which are not fully accounted for in global emissions budgets, will greatly reduce the amount of greenhouse gases that humans can emit to remain below 1.5 °C or 2 °C. The Paris Agreement provides ongoing opportunities to increase ambition to reduce society’s greenhouse gas emissions, which will also reduce emissions from thawing permafrost. In December 2020, more than 70 countries announced more ambitious nationally determined contributions as part of their Paris Agreement commitments; however, the carbon budgets that informed these commitments were incomplete, as they do not fully account for Arctic feedbacks. There is an urgent need to incorporate the latest science on carbon emissions from permafrost thaw and northern wildfires into international consideration of how much more aggressively societal emissions must be reduced to address the global climate crisis.

We’ve a lot to keep track of, much of it shifting beneath our feet. Natali et al is open access and free to read. 

Moving targets #2

What can change the mind of a person stubbornly resistant to facts? Certain kinds of facts, maybe. Grant McDermott sets up an experiment to assess how self-professed climate “skeptics” adjust their beliefs when confronted with evidence of climate change from instrumental records. For McDermott the interest of the experiment lies in unifying seemingly disparate theories of accessibility of “skeptic” cognition but his paper is also suggestive of yet another set of mental buttons to push in the pursuit of progress. The abstract:

How much evidence would it take to convince climate skeptics that they are wrong? I explore this question within an empirical Bayesian framework. I consider a group of stylized skeptics and examine how these individuals rationally update their beliefs in the face of ongoing climate change. I find that available evidence in the form of instrumental climate data tends to overwhelm all but the most extreme priors. Most skeptics form updated beliefs about climate sensitivity that correspond closely to estimates from the scientific literature. However, belief convergence is a nonlinear function of prior strength and it becomes increasingly difficult to convince the remaining pool of dissenters. I discuss the necessary conditions for consensus formation under Bayesian learning and show that apparent deviations from the Bayesian ideal can still be accommodated within the same conceptual framework. I argue that a generalized Bayesian model provides a bridge between competing theories of climate skepticism as a social phenomenon.

Skeptic priors and climate consensus is open access and free to read.

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. 

  • 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.

Articles are presented with a title link via the original publisher URL so as to preserve provenance information, and when (usually) available, a more permanent DOI link. When a publicly accessible PDF version of an article is found, a direct link is provided.

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.
