A new paper on Baffin Bay polar bears reports data on body condition and litter sizes collected as part of a major study of the region completed in 2013 compared to sea ice declines since the 1990s; based on a computer model, the authors predict that in 37 years time (if sea ice declines continuously), the incidence of twin litters could “largely disappear.” However, no decline in population numbers was predicted and a critical caveat acknowledges that factors other than changes in sea ice could have affected the body condition and litter size data the authors analyzed, which means the conclusions are scientifically inconclusive.
The last (2013) polar bear population survey of Baffin Bay (SWG 2016) generated an estimate of almost 3,000 (2,826; range 2,059-3,593), which means that regardless of some slight changes in body condition and litter size over the last two decades (which may or may not have been caused by loss of sea ice), there are currently a lot of bears in Baffin Bay.

Unbelievably wrong: A psychologist has told parents to assure their children that rising sea levels might be an immediate threat to polar bears – but not to kids in the UK. She says this is “putting things into perspective” for anxious kids but is horrifyingly and almost laughably far off the mark.
The amount of ignorance about polar bears from those who still consider the species an appropriate icon for catastrophic climate change never seems to end.

In this short interview clip with Friends of Science director Michelle Stirling, I talk about the drowning polar bears in Al Gore’s 2007 movie that he implied would lead to the extinction of the species. Except that it didn’t…
My new book, The Polar Bear Catastrophe That Never Happened, explains why.

Despite a demand by radical protest group Extinction Rebellion that governments “tell the truth” about climate change, it’s apparent that when it comes to walrus extinction risk they prefer the contrived walrus tragedy porn compiled by David Attenborough and his Netflix cronies over scientific evidence.
For this group of radical protesters, ‘the truth‘ is a narrative that serves their traffic-disrupting purposes. Since many gullible people – young and old – were horrified by the Netflix claim that hundreds of walruses in the western Arctic had hurled themselves off a cliff because of human-caused climate change, Extinction Rebellion plan to exploit this emotional connection during upcoming protests, apparently believing that what Attenborough told them was a fact. But in accepting docu-drama content without question, they are rejecting the best available science produced in 2017 by biologists who determined that Pacific walrus are not being harmed by the effects of climate change and are not threatened with extinction.

Just out this morning:
“Today, U.S. Secretary of the Interior David Bernhardt unveiled improvements to the implementing regulations of the ESA designed to increase transparency and effectiveness and bring the administration of the Act into the 21st century.” USFWS Press Release, 12 August 2019.
Although much hue-and-cry will be written by conservation organizations and the media (here is one), I am providing for easy reference here links to the original press releases and documents issued this morning by the Department of the Interior and the US Fish and Wildlife Service. I am also providing pdf copies of the official documents to appear shortly in the Federal Register and quote the above USFWS press release in full.
It remains to be seen whether polar bears or other Arctic species of interest to me and readers of this blog will be affected. The new changes affect both the listing and delisting process as well as designation of critical habitat.
