The annual summer sea ice minimum in the Arctic has been reached and while the precise extent has not yet been officially determined, it’s clear this will be the ‘second lowest’ minimum (after 2012) since 1979. However, as there is no evidence that polar bears were harmed by the 2012 ‘lowest’ summer sea ice this year’s ‘second-lowest’ is unlikely to have any negative effect.
This is not surprising since even 2nd lowest leaves summer ice coverage in the Arctic at the level sea ice experts wrongly predicted in 2005 wouldn’t be seen until 2050 (ACIA 2005; Amstrup et al. 2007; Wang and Overland 2012) and this is the same amount of summer sea ice that polar bear experts incorrectly predicted would cause 2/3 of all polar bears to disappear. My book explains how it all went wrong: The Polar Bear Catastrophe That Never Happened.
In this summary of how polar bears have been doing since the the lowest sea ice minimum in 2012, I show that contrary to all predictions, polar bears have been thriving despite reduced summer ice in the Barents, Chukchi and Southern Beaufort Seas, and because of unexpectedly short ice-free seasons in Hudson Bay and less multiyear ice in the Canadian Arctic Archipelago.
UPDATE 21 September (10:20 PT): NSIDC has just announced the Arctic sea ice extent minimum (preliminary) for 2020 at 3.74 mkm2 reached on 15 September. See full report here.

An excellent summary of recent points I’ve made in my latest book and on this blog about the recent push to keep polar bear extinction panic alive with a new model of impending doom was published two days ago in the Spectator UK by columnist Ross Clark (23 July 2020, in Coffee House).
“Wouldn’t it be nice if we could debate climate change for five minutes without hearing about polar bears or being subjected to footage of them perched precariously on a melting ice floe? But that is a little too much to expect. Polar bears have become the pin-ups of climate change, the poor creatures who are supposed to jolt us out of thinking about abstract concepts and make us weep that our own selfishness is condemning these magnificent animals to a painful and hungry end.”
Read the whole thing here.
PS. I noticed Clark refers to me as an anthropologist. I have requested a correction because I am a zoologist.

Here I take a detailed look at sea ice and polar bear population health information available for Western Hudson Bay and the Southern Beaufort compared to the Barents and Chukchi Seas. Data from the first two regions – but especially Western Hudson Bay – are used repeatedly to proclaim that a pronounced decline in summer sea ice since 1979 has caused harm to the health of global polar bear populations even though data from the second two regions strongly contradict such a conclusion, as I’ve pointed out in my fully referenced book, The Polar Bear Catastrophe That Never Happened.
These contradictions mean that studies from Western Hudson Bay and the Southern Beaufort should not be used to extrapolate to the rest of the Arctic with regard to how polar bears are responding to reduced summer sea ice. The plea to ‘Save Our Sea Ice‘ for the sake of polar bear survival is a climate change marketing slogan, not a scientific assessment.

This updated blog post of mine from last year is as pertinent now as it was then: it’s a fully-referenced rebuttal to the misleading ‘facts’ so often presented this time of year to support the notion that polar bears are being harmed due to lack of summer sea ice. Polar Bears International developed ‘Arctic Sea Ice Day’ (15 July) to promote their skewed interpretation of polar bear science at the height of the Arctic melt season. This year I’ve add a ‘Polar Bears and the Arctic Food Chain‘ graphic, which readers are free to download and share. For further information, see “The Polar Bear Catastrophe That Never Happened“.

A few days ago I had the pleasure of talking with Anthony Watts from WUWT as part of his new podcast series. Listen to it here.
Below, I’ve copied a post from earlier this year that summarizes some misconceptions about polar bear conservation status and population size. I reiterate here (with links added for convenience) what I said last month:
The polar bear data are contradictory: contrary to predictions, several polar bear subpopulations (at least four of them) are indeed thriving despite much reduced summer sea ice [Chukchi Sea, Barents Sea, Kane Basin, M’Clintock Channel, as well as Foxe Basin and Davis Strait]. I have chosen to emphasis that good news, while Stirling and Derocher choose to emphasize the data that seem to fit their predictions [Western Hudson Bay and Southern Hudson Bay]. This is a classic conflict that happens all the time in science but presents no proof that I’m wrong or that the PragerU video is inherently ‘false’.
Note that Western Hudson Bay bears were last counted in 2016 but have had five good sea ice seasons in a row now, including this year by the look of it, so if ‘lack of sea ice’ is really the cause of the statistically-insignificant decline, then population numbers should be back up. And here is my video about the National Geographic video of the starving polar bear blamed on climate change mentioned by Anthony in the interview:

Facebook has labelled a recent short PragerU polar bear video as “false information” based on a ClimateFeedback review featuring statements by Andrew Derocher and Ian Stirling published 18 May 2020.
The video, posted on Facebook 5 May 2020, is also available here and here. Also here on the PragerU website.
I was approached yesterday by Nick Coltrain, a reporter for the Des Moines Register and USA Today, asking for a statement about the accuracy of the PragerU video, which cites me as a source for two of their three ‘inconvenient facts.’
My comments are below but I reminded Nick that what is going on is a classic conflict that happens all the time in science: it presents no proof that I’m wrong or that the PragerU video is ‘false information’. Climate Feedback is not ‘factchecking’: it is presenting its preferred side of a disputed science issue.

A review of a newly-released (22 April 2020, on Earth Day) report commissioned by Canada’s Department of Fisheries and Oceans on the state of the Arctic seas published today in the National Post is a must read. It highlights the report’s emphasis that while the changes going on in our northern seas are indeed marked, they do not necessarily spell doom.
Oddly, polar bears are primarily represented in the report by an overview account of the special case of Western Hudson Bay – an outlier among Canadian subpopulations – that puts special emphasis on the claimed decline in body condition blamed on recent sea ice changes that is not supported by any recent data (Crockford 2020).

On this first anniversary of the publication of The Polar Bear Catastrophe That Never Happened, it’s a day of celebration for me. The book has informed thousands about how and why the scary stories about the imminent demise of polar bears due to human-caused global warming failed so miserably. It is a story of the triumph of facts over assumptions and a perfect example of why scientific observations trump model predictions. It is also a study of science at its worst: how a close-knit community of scientists groomed by a few senior researchers was able to cast out an insider who refused to tow the line on their climate change agenda – and mobilized mobs to attack outsiders who questioned their authority.
If you haven’t read it, now may be the perfect time. Many of you will be forced or encouraged to stay at home because of Covid-19 concerns, so here is one way to put the time to good use. Ebooks are perfect for this situation. If you don’t like Amazon, Smashwords has an ebook version here.
Smashwords also has an ebook version of my novel, EATEN. This polar bear attack thriller is a timely read for a number of reasons but primarily because it’s the story of an animal epidemic with horrific consequences quite different from the one we are facing at the moment.
My polar bear science book for kids, Polar Bear Facts and Myths in ebook form might be the perfect diversion for kids at home who need interesting educational material.
You’ll find links to all of my books, in all countries and all outlets, at my personal website here.

Over 100 thousand views since September:
Tomorrow I will be giving a public lecture in Paris on polar bear conservation success and the spectacular failure of the polar bear survival models used to scare children senseless.
However, while I was in London a few days ago I spoke with James Delingpole, author and columnist at Breitbart who has recently taken to producing podcast and video interviews.
Yesterday, he posted a column summarizing our discussion, with a link to the entire podcast: “WATCH: Canadian Professor Lost Her Job for Telling the Truth About ‘Endangered’ Polar Bears.” Read it here.
