evidence: The polar bear data are contradictory: contrary to predictions, several polar bear subpopulations (at least four of them) are indeed thriving despite much reduced summer sea ice. I have chosen to emphasis that good news, while Stirling and Derocher choose to emphasize the data that seem to fit their predictions. This is a classic conflict that happens all the time in science but presents no proof that I’m wrong or that the PragerU video is inherently ‘false’. [...] In short, it is indeed true that ‘Polar bears are thriving even where sea ice is diminishing.’ See also my 2018 opinion piece on the National Geographic ‘starving’ polar bear video in the Financial Post here. Climate Feedback reviewed that piece with statements by Steven Amstrup and Andrew Derocher, which I countered here, here, and here. [...] In addition to the thriving condition of Barents Sea bears discussed above (Aars 2018; Aars et al. 2017; Lippold et al. 2019), Chukchi Sea polar bears are also doing much better than they were in the 1980s despite much reduced summer sea ice. These results are documented in a number of peer-reviewed papers on the topic (ACSWG 2018; Regehr et al. 2018; Rode and Regehr 2010; Rode et al. 2013, 2014, 2018). Ringed and bearded seals are similarly thriving despite less summer ice (Crawford et al. 2015).
