Posted onOctober 26, 2022|Comments Off on Emperor penguins join polar bears on ESA list of threatened species based on flawed climate models
Yesterday, the US Fish and Wildlife Service announced it will classify the Emperor penguin as ‘threatened’ with extinction under its Endangered Species Act (ESA) based on what are known to be flawed climate models, to take effect next month. This is despite the fact that Emperor penguin numbers increased between 2009 and 2019, an IUCN Red List reassessment in 2019 did not reverse its 2018 decision (still listing it as ‘near-threatened’, not ‘vulnerable’), and member-nations refused earlier this year to enact an Antarctic Treaty to protect the birds. Conservation activists of all stripes are filled with glee at this bettter-than-nothing decision for a species nowhere near extinction because it means more money for them.
Though emperor penguins are not found naturally in the U.S., the endangered species protections will helpincrease funding for conservation efforts. U.S. agencies will also now be required to evaluate how fisheries and greenhouse gas-emitting projects will affect the population…
Posted onMay 10, 2021|Comments Off on How are polar bears doing 15 years after the IUCN declared them ‘vulnerable’ to extinction?
The beginning of this month was the 15th anniversary of the day the IUCN declared polar bears ‘vulnerable’ to extinction because of climate change, the first time such a designation had ever been made. It was based on the opinion of polar bear specialists who examined the vague information available at the time and decided that in 45 years the bears might be in serious trouble. This decision changed the way the IUCN assessed species risk and led to mass confusion for the general public, who falsely assumed polar bear numbers had already declined by a huge amount.

No early breakup of Hudson Bay sea ice again this year: there is still extensive thick first year ice over most of Hudson Bay and all female polar bears fitted with tracking collars in Western Hudson Bay are still on the ice:
W Hudson Bay polar bears still out on the ice that’s packed together by winds. AE Derocher, 12 June 2020
Breakup of Hudson Bay sea ice as it relates to polar bear movement to land has been about the same since 1999 (about 2 weeks earlier than in the 1980s) and this year is shaping up to be no different: there is still no declining trend in date of sea ice breakup in Western Hudson Bay despite repeated predictions of imminent doom. An especially ‘early’ breakup year would have bears ashore before 15 June. Last year (2019) the first WH bear onshore was caught on film 5 July and problem bears were not recorded onshore in Churchill until the 2nd week of July.

The chart below shows what sea ice thickness over Hudson Bay was like at the first week of May in a so-called a‘good year’(2019) – when polar bears came off the ice in excellent condition late in the summer and left early in the fall (‘thick first year ice’ is dark green and indicates ice greater than 1.2m thick):
Hudson Bay ice conditions this year appear to be shaping up to be as good or better than last year for polar bears yet specialist researchers and their cheerleaders have still been claiming that bears in this region – Western and Southern Hudson Bay – are doomed because of poor ice conditions. It’s no wonder they still haven’t published the data they’ve been collecting on polar bear body condition and cub survival over the last 15 years or so (Crockford 2020). With most field work cancelled for this year, what’s their excuse for not getting that done? Continue reading

Posted onMay 5, 2020|Comments Off on New Paper: Body condition of Barents Sea polar bears increased since 2004 despite sea ice loss
A recent paper that attempted to correlate pollution levels and body condition in Barents Sea polar bears reports it found body condition of female bears had increased between 2004 and 2017 despite a pronounced decline in summer and winter sea ice extent.
“Unexpectedly, body condition of female polar bears from the Barents Sea has increased after 2005, although sea ice has retreated by ∼50% since the late1990s in the area, and the length of the ice-free season has increased by over 20 weeks between 1979 and 2013. These changes are also accompanied by winter sea ice retreat that is especially pronounced in the Barents Sea compared to other Arctic areas” [Lippold et al. 2019:988]
Posted onSeptember 29, 2019|Comments Off on New polar bear horror emerges out of advice to parents on eco-anxiety in kids
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.
Amstrup’s model predicted that 2/3 of the world’s polar bears would be gone if sea ice got as low as it has been since 2007 but it was spectacularly wrong: polar bears are healthier and more numerous than 50 years ago.
Global polar bear population size estimates to 2018. From Chapter 10 of The Polar Bear Catastrophe That Never Happened (Crockford 2019).
“This year’s polar bear season is going to be big for our team, perhaps our biggest yet. Not only do we have an amazing schedule of Tundra Connections webcasts and live chats, but we’re also working with an array of media to tell stories and spread awareness about polar bears and the threats they face in a warming Arctic. This is especially important following another summer of massive sea ice loss in the Arctic and amidst overwhelming global momentum pressuring world leaders to address the climate crisis.”
Below is an excerpt from an interesting story from 2010 on how PBI controls the ‘polar-bears-are-doomed/save-our-sea-ice‘ narrative presented to the media and innocent tourists who just come to see polar bears in the wild.
Posted onAugust 12, 2019|Comments Off on USA finally updates Endangered Species Act after 45 years & the decision is final
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.
