Dodgy new clarification of global polar bear population estimate (yes, another)

In an attempt to get themselves out of a mess of their own making, the IUCN Polar Bear Specialist Group (PBSG) has just dug their hole even deeper.

Although the minutes of their 2014 June meeting (pdf here) contained this statement…

K. Laidre summarized the need for the PBSG to do a better job of communicating accurate and balanced science about polar bears.” Pg. 28

…you might conclude, after reading the rest of this post, that polar bear specialists don’t really understand what these terms mean.

Due to the flack they have been catching over their global polar bear population estimates, the PBSG determined that another clarification was in order. [As opposed to the first clarification, a footnote the group planned to insert in an upcoming report, which PBSG chairman Dag Vongraven sent to me in May)]

The new clarification, apparently co-authored by Steve Amstrup and Andy Derocher (PBSG 17 minutes, pg. 33 – copied below), makes an astonishingly bold claim that I can easily show is untrue.
