The Harvey et al. Bioscience article that attacks this blog and others that link to it — a veritable tantrum paper that took 14 people to write — included a sciency-looking analysis of peer-reviewed articles said to have been retrieved by the database “Web of Science” using the search terms “polar bear” and “sea ice.”
“Consensus science pounds the floor and chews the carpet in angry frustration.” [mpainter, 25 December 2017]
“Of the 92 papers included in the study, 6 are labeled ‘controversial.’ Of the remaining 86, 60 are authored or co-authored by Stirling or Amstrup, or Derocher. That is, close to 70% (69.76%) of the so-called ‘majority-view’ papers are from just three people, 2 of whom wrote the attack paper themselves.” [Shub Niggurath, crossposted at Climate Scepticism, 14 December 2017]
The bias of co-author papers used to represent the “expert consensus” on polar bear biology is only one problem with this particular attempt at making the Harvey paper look like science: in fact, the short list of papers used for analysis is a far cry from the original number returned by Web of Science for the search terms the authors say they used in the supplementary information.
How that large original number (almost 500) was whittled down to less than 100 is not explained by the authors. As a consequence, I can only conclude that the “methodology” for paper selection was likely defined after the fact. While the method of paper selection sounds simple and reasonable, apparently not one of the Harvey et al. paper’s co-authors checked to see if it was plausible (or didn’t care if it was not).
