Viability of greenhouse gas removal via the artificial addition of volcanic ash to the ocean(not open access, unfortunately)walks us through the numbers on a particular means of CO2 removal, addition of volcanic tephra to the ocean. The mechanism is straight chemistry and the cost is fully an order of magnitude less than other proposed methods. For the world population and emissions of approximately 4.982 metric tons per capita (2014) we’re looking at the number above in US dollars per year to entirely solve our global emissions problem (assuming the system would scale so large). Roughly US$ 2 quadrillion/year, done cheap. Surely there’s a less expensive way? What could it be?
In fairness to authors Longman, Palmer and Gernon, they’re certainly not proposing to entirely solve our CO2 problem with this intriguing and objectively efficient method. The admirable affordability of the scheme resulting still in such ballooning numbers is simply another indicator that we need to start with reduction of CO2 emissions, push the biggest and easiest button.
Until this edition of New Research we’ve been using an indigenous tool to assist with identifying open access documents. Recently somebody dropped a clue brick on our heads (thanks David!) and made us aware of Unpaywall.org. Unpaywall operates a sophisticated, legally respectful system to identify open access publications. Further investigation revealed an API for accessing their database. Although our own system performed remarkably well in comparison to Unpaywall, it required steady drain from a limited pool of time to maintain and as well was never going to match Unpaywall results. With this edition we’ve integrated the Unpaywall API.
As before, open access items are flagged.
Items found in the Unpaywall system will feature at minimum a permanent DOI access link, one that does not change when/if a publication changes notional URLs leading to articles.
When available, direct links to PDF versions of articles are presented. Clicking “PDF” for a article offering this option will directly load a paper.
As Unpaywall does not catch preprints notices that we cover, each edition of New Research will be reprocessed some weeks after publication, to update meta information.
Unpaywall offers a browser extension for Chrome 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 about 1/4 of RSS output makes the cut.
