2017 in review: polar bear prophesies of doom more at odds with current reality

Tales of doom and gloom about polar bears reflect what some people think might happen in the future, not what is happening right now.  Currently, polar bears are doing just fine despite the low summer sea ice coverage they’ve experienced since 2007 (Crockford 2017a; York et al. 2016). In other words, there has been no global population decline as predicted: officially, the numbers were 22,000-31,000 (or 26,500 average) in 2015 (Wiig et al. 2015) but about 28,500 when estimates published since then are included (Aars et al. 2017; Dyck et al. 2017; Matishov et al. 2014; SWG 2016), up from about 22,500 in 2005).

The doomsayers can’t stand to have someone provide the public with unbaised evidence of this failure so they attack my scientific integrity with an academically weak and aggressively vindictive ‘peer-reviewed’ paper (Harvey et al. 2017, in press) that you’ll hear more about in the new year.

Bottom line: 2017 saw abundant good news stories about polar bears, which I’ve summarized below. See also Crockford 2017b: Twenty reasons not to worry about polar bears, the 2017 update and my 2017 block-buster video, Polar Bear Scare Unmasked: The Saga of a Toppled Global Warming Icon:
