Longest-swimming polar bear lost less weight than if she had stayed onshore

Recent media hype over swimming polar bears in the Southern Beaufort has been quite spectacular (still going strong today at the Washington Post here) but a close look at relevant data shows the message is bogus. Researchers admit (in their methods section) they couldn’t tell if bears said to have swum “non-stop” actually hauled out for half a day or more to rest on small ice flows invisible to satellites and astonishingly, the bear getting all the media attention – who swam the longest of any bear – lost less weight than a bear would have done simply sitting on shore for the same length of time.

Climate Hustle knows: Ten dire predictions that have failed as global polar bear population hits 20-31k

[Reposted today from earlier this year in support of the 2 May release of the intentionally funny documentary, Climate Hustle (across the US and a few Canadian locations) because host Marc Morano knows that polar bear numbers have not declined as people have been led to believe, see the trailer below]

Grim predictions of the imminent demise of polar bears – their “harsh prophetic reality” as it’s been called – have been touted since at least 2001. But such depressing prophesies have so widely missed the mark they can now be said to have failed.

While polar bears may be negatively affected by declines in sea ice sometime in the future, so far there is no convincing evidence that any unnatural harm has come to them. Indeed, global population size (described by officials as a “tentative guess“) appears to have grown slightly over this time, as the maximum estimated number was 28,370 in 1993 (Wiig and colleagues 1995; range 21,470-28,370) but rose to 31,000 in 2015 (Wiig and colleagues 2015, pdf here of 2015 IUCN Red List assessment; range 20,000-31,000).

Here are the failed predictions (in no particular order, references at the end):

More politics of polar bears courtesy WWF: impaled polar bear sculpture

The offensively tasteless “art” produced by Danish sculptor Jens Galschiøt, in collaboration with the World Wildlife Fund, for the specific purpose of influencing politics has reappeared.

It’s simply the Politics of Polar Bears on a global scale that has no basis in science: polar bear numbers have not declined as CO2 has risen. Jens Galschiøt’s tasteless and costly message funded by WWF is not much better than Plane Stupid’s 2009 ad of polar bears falling from the sky (see below). It’s just about as asinine and not supported by science. Continue reading

Polar bear biologists imply “summer sea ice” and “sea ice” are synonymous

According to sea ice experts, winter sea ice habitat for polar bears is not expected to decline at all by 2050 and the critical spring sea ice that polar bears need for gorging on young seals and for mating is not predicted to change much (Durner et al. 2007, 2009), which is why computer modelled predictions about the dire future for polar bears only assessed the potential future effects of declining summer sea ice (e.g. Amstrup et al. 2007; Stirling and Derocher 2012). Note spring is April-June.

See if that fact is clear in the interview responses by out-spoken polar bear biologists that has just been published in the polar bear portion (“Beyond the polar bear”) of this year’s University of Alberta magazine spring climate change feature. If you can get past the “canaries in the coal mine” opener…

Worrywart biologists fuel media fearmongering over winter sea ice levels

Have you heard the old adage, “Don’t buy trouble”? I’m thinking we could use a lot more of that attitude from polar bear and Arctic seal biologists these days.

In an interview with CBC News yesterday, Department of Fisheries and Oceans Canada (DFO) seal specialist Mike Hammill fed the fear the media wanted to hear while admitting this year’s low ice levels in the Gulf of St. Lawrence will not affect harp seal numbers significantly (7 March 2016, Lack of ice means fewer seal pups off the Magdalen Islands this year: Researcher says impact on overall herd limited, but ice patterns over time could be concern”).

And University of Alberta’s Andrew Derocher has been busy tweeting his heart out that slightly lower than average sea ice levels this winter could mean a “challenging” spring for some polar bears – as if spring isn’t always challenging for some bears (especially young bears that are inexperienced hunters and low in the social hierarchy – meaning bigger, older bears often steal their kills – and old bears that are running out of steam).

More Churchill polar bear captures due to increased vigilance not global warming

Polar bear specialists just don’t get it: virtually no one except the ever-gullible media believes their exaggerated stories of doom. Yet they keep trying and with every lie and misrepresentation of fact, they erode the confidence of the public. Unfortunately, it’s not just trust in polar bear specialists that’s being eaten away, it’s trust in science generally.

Churchill polar bear encounters up in 2015_CBC headline Feb 28 2016

This time, it’s a head-line grabbing piece about the number of problem polar bears in Churchill, Manitoba (written by Chinta Puxley) that made the usual media rounds yesterday (CBC News, CTV News, Global News, Huffington Post, Winnipeg Sun, The Globe and Mail). The main culprits are Daryll Hedman, regional wildlife manager for Manitoba Conservation, and polar bear biologist Andrew Derocher.

However, it’s hard not to see that the increased number of bears captured by Manitoba Conservation officers around Churchill can be best explained as a natural reaction by officials to a particularly frightening polar bear attack in 2013. Continue reading

Biggest threat to polar bears reconsidered

What presents a bigger risk to current polar bear populations: natural hazards that have already proven deadly or potential, yet-to-be-realized threats prophesied to occur due to human activities? That’s a perfect question for International Polar Bear Day.

Dag Vongraven, chair of the IUCN Polar Bear Specialist Group, remarked last year that “until 2001, everything was fine.

Polar bear researchers thus assume that 2001 was the year climate change became the new over-hunting – but is it true? What are the relative harms presented by proven natural causes, potential human-caused threats, and predicted threats due to sea ice declines blamed on global warming? Considered objectively, is climate change really the single biggest threat to polar bear health and survival right now?
