Full podcast of TV interview with Andrew Bolt in Australia talking about polar bears

This 10 minute television interview aired a few hours ago on The Bolt Report (Sky News Australia, 26 March 2019). A short excerpt was made available as a tweet but a link to the full length podcast is below.

Ironically, despite the huge effort made by polar bear specialists and climate change activists to silence and discredit me over the last year or so, all it’s done is made more people willing to listen to what I have to say. My new book is selling phenomenally well and getting great reviews: if you haven’t ordered your ebook or paperback copy, you can do so here.


Latest global polar bear abundance ‘best guess’ estimate is 39,000 (26,000-58,000)

It’s long past time for polar bear specialists to stop holding out for a scientifically accurate global estimate that will never be achieved and determine a reasonable and credible ‘best guess’. Since they have so far refused to do this, I have done it for them. My extrapolated estimate of 39,000 (range 26,000-58,000) at 2018 is not only plausible but scientifically defensible.

In 2014, the chairman of the IUCN Polar Bear Specialist Group (PBSG) emailed me to say that their global population size number ‘has never been an estimate of total abundance in a scientific sense, but simply a qualified guess given to satisfy public demand.’

In my new book, The Polar Bear Catastrophe That Never Happened, I contend that this situation will probably never change, so it’s time to stop holding out for a scientifically accurate global estimate and generate a reasonable and credible ‘best guess’. Recent surveys from several critical polar bear subpopulations have given us the information necessary to do this.

UPDATE: I have made this a sticky post for a while: new posts will appear below.

This week: New book release & Glenn Beck interview talking about polar bear numbers

The Polar Bear Catastrophe That Never Happened is almost here! The book is scheduled for release (in paperback and ebook formats) on Tuesday 19 March 2019. Tuesday is also the day I’ll be talking to Glenn Beck on his radio show (11 am ET) about polar bear population numbers and my book. How many polar bears are really out there now, you ask? My book has a credible new answer that may surprise you.

Before National Geographic apologized for hyping the starving polar bear video they exploited it to promote a message of doom

Back in early February this year, National Geographic used their “this is what climate change looks like” video to promote a newly-published polar bear study and endorse conservation activist Steven Amstrup’s debunked and abandoned prediction of polar bear catastrophe due to global warming. Even with this revelation, the starving polar bear video fiasco is not yet over.

Polar Bears Really Are Starving Because of Global Warming, Study Shows (National Geographic, 1 February 2018).

The initial focus of the February 2018 National Geographic article was a study published that week by Anthony Pagano and colleagues (Pagano et al. 2018; Whiteman 2018), suggesting that a few polar bears in the Southern Beaufort Sea were not getting enough to eat in early spring from 2014-2016 (with no reference to sea ice conditions; see my critique of that study here).

Then, Steven Amstrup, spokesman for activist organization Polar Bears International, is quoted as saying (my bold):

“If these results hold up [from Pagano’s study], then it shows that the loss of sea ice may have a bigger impact on the bears than previously thought, said Amstrup, a former USGS polar bear expert. Amstrup’s own 2010 study projected that continued decline in sea ice would reduce the global population of bears by two thirds, to less than 10,000 by 2050.

Seriously, no one except Amstrup and his Polar Bears International fanbase are citing his outlandish 2010 prediction, which is just a rehash of his 2007 USGS internal report and its 2008 journal version (Amstrup 2007, 2008, 2010). Amstrup’s prediction is not only a failure (Crockford 2017, 2018; Crockford and Geist 2018) but it’s been abandoned by his colleagues for vaguer or more moderate predictions of population decline (e.g. Atwood et al. 2015, 2016; Regehr et al. 2016).

National Geographic has now apologized for saying that the emaciated bear in the SeaLegacy video they so heavily promoted was “what climate change looks like” (and replaced the caption with “this is what starvation looks like,” even though there is no evidence the bear was starving from lack of food rather than from severe illness).

But the damage is done. By endorsing the discredited polar bear survival predictions of Amstrup along with the video, National Geographic degraded itself even further in the eyes of rational and informed readers. I’ll have more to say on the SeaLegacy video exploited by National Geographic and its message that starving polar bears are victims of climate change in a subsequent post: we haven’t yet reached the end of this debacle.

Fat polar bears [and lots of them] drive public confidence in future of the species

What is causing the death of the polar bear as a climate change icon? Fat bears are part of it, but mostly it’s the fact that polar bear numbers haven’t declined as predicted.

Western Hudson Bay polar bears around Churchill, Manitoba appear mostly in good shape this summer despite the very late freeze-up last fall, including the very fat bear caught on camera below (see more great pictures here):

Churchill_PolarBears_FAT bear post_21 Aug 2017

Not only have we been seeing pictures of fat bears rather than starving bears in recent years but there are lots of them, in Western Hudson Bay and other seasonal sea ice regions where there should be none (if the models had been correct). No wonder polar bears are falling out of favour as an icon for catastrophic human-caused global warming.

[Here’s another picture of a fat bear, this one from Svalbard]

Excuses for why the public is no longer worried about the future of polar bears include a recent claim by climate scientist Michael Mann that “by making polar bears and penguins the poster child for climate change, we have wrongly conveyed that this is some exotic problem far off.

But none of these apologists acknowledge the simple truth: the models that  predicted catastrophe for polar bears due to diminished summer sea ice turned out to be wrong. The sea ice declined but polar bears flourished. Polar bears in seasonal sea ice ecoregions like Western Hudson Bay and Baffin Bay didn’t die off due to climate change as people were told would happen — why should they believe any of the other scare stories?

In and around Churchill, where tourists flock to see Western Hudson Bay polar bears up close and personal, one bear in good condition recently ran through town:

Overall, there have been fewer problems or conflicts this year in Churchill compared to last (after 6 weeks of onshore living), see below.

Polar bears are no longer a useful global warming icon because they are thriving despite diminished sea ice: Churchill area polar bears are a good example.

Exposing the failed polar bear scare to a an enthusiastic and influential audience

I’ve just returned from a few days in Washington DC, where I presented the details on the global warming icon that refused to die as modeled (see my slide #12 below) to an enthusiastic and influential audience at The Heartland Institute‘s 12th International Climate Change Conference (ICCC-12).

Crockford 2017_Slide 12 screencap

Polar bear science got some long overdue scrutiny by a large number of people at this meeting. Not unexpectedly, a good many folks were surprised and outraged to learn how the polar bear/sea ice situation has actually unfolded compared to the predicted outcome and on-going media hype.
