The Polar Wildlife Report is a peer reviewed summary of the most recent information on polar animals, relative to historical records, based on a review of 2022 scientific literature and media reports. It is intended for a wide audience, including scientists, teachers, students, decision-makers and the general public interested in animals that live in Arctic and Antarctic habitats, including polar bears, killer whales, krill, and penguins.

There is irrefutable evidence from Barents and Chukchi Sea subpopulations, among others, that polar bears are fat and reproducing well despite marked declines in summer sea ice over the last two decades. These indicators of physical and reproductive health, in any species, are signs of thriving populations. However, these facts negate the premise that polar bears require abundant summer sea ice to flourish, and that creates a problem for polar bear specialists who continue to make that claim (Amstrup et al. 2007; Crockford 2017, 2019).
In other words, the assessment that polar bears are currently thriving is not based solely on estimates of a slight increase in global population size but on published data gathered from field studies on the bears’ physical and reproductive health.
Oddly, biologists repeatedly turn to data from Western Hudson Bay to drive home to the public their preferred message that polar bear health and abundance are being negatively affected by recent summer sea ice declines. However, they fail to mention that robust field data from many other regions, including the Barents and Chukchi Seas, support the opposite conclusion. Moreover, wherever possible, they mumble under their breath (or leave out entirely) the fact that poor ice conditions could not be blamed for a 27% decline in polar bear numbers in Western Hudson Bay since 2016 — because their own data showed sea ice conditions had been strong!

There’s abundant sea ice in the Bering, Greenland and Labrador Seas, although less than usual in the Barents Sea because strong winds drove the ice north. Any time there is a bit less sea ice than usual the catastrophists begin caterwauling but this time the rhetoric is a little different.

Just a short update regarding progress on the book. I am deciding on a cover design while addressing suggested changes as they come back from the editor, and preparing marketing material. If all goes to plan, I am on track for a March publication date–thanks to your support.
In the early 1960s paleontologist Bjorn Kurtén thought that polar bears likely arose from a brown bear ancestor based on fossil evidence alone, and his estimate of when this happened was determined by the age of fossil remains of both species. As I will show in the chapters that follow, despite more fossil evidence being available and additional evidence from molecular genetic studies, his estimate is still the most likely time frame for when the polar bear came to be.

The veterinarian who examined the bear responsible for the fatal attack in Wales, Alaska, three weeks ago said the bear was an “older” adult male in poor physical condition: the most dangerous bear for anyone to encounter. Recall the armed cruise ship guard who was ambushed and mauled by a desperately thin bear in July 2018 in the Svalbard archipelago–and only survived because his colleague was able to shoot the bear quickly. In this most recent attack, Summer Myomick and her 1-year-old son, Clyde Ongtowasruk didn’t stand a chance as they were ambushed in a driving snowstorm just steps from the safety of the community school they had just left.
Results of a complete necropsy won’t be available for months. Quotes from the news report below.
