“Polar bears continue to be described as ‘canaries in the coal mine’ for the effects of human-caused climate change, but the evidence shows they are far from being a highly-sensitive indicator species.” Susan Crockford, 24 February 2021
You’ll find the evidence I allude to above – backed up by references to the peer-reviewed literature – in my many publications (Crockford 2015; 2017; 2019, 2020, 2021). My open-access research paper from 2017 has been downloaded more than 6,000 times and despite this being an online forum for legitimate scientific critique, none has been offered. My comprehensive polar bear science book released just two years ago (see below) has a 4.7/5.0 star rating on Amazon, with 132 reviews so far.
For recent blog post examples of the evidence that polar bears are thriving despite profound summer sea ice loss, see this discussion about the many contradictions that exist for claims that sea ice declines have caused harm to polar bear health and survival and this review of the evidence that less summer sea ice has meant more food for polar bears.
For those who haven’t seen it, I’ve copied below the preface from The Polar Bear Catastrophe That Never Happened. This book is an antidote to the emotional blackmail coming at the public from all sides by journalists, polar bear specialists, and elite influencers like David Attenborough.
