Maclean’s blames global warming for polar bear visits to Newfoundland

Without a shred of evidence, Canada’s Maclean’s magazine claims recent polar bear sightings in Newfoundland and Labrador are due to global warming — and concludes that such incidents are bound to get worse.

But since it’s likely that polar bear populations in Davis Strait are still increasing (as they were in 2007), Maclean’s might be correct in their prophesy that bear visitations are bound to get worse — just not for the reason they think.

Without any justification or even a quote from an expert, the author of this piece (Meagan Campbell)  blames man-made global warming for recent polar bear visits to Labrador and Newfoundland:

“Since bear sightings in the early winter have been linked to climate change, some parents are more concerned for their future grandchildren.” 

That’s just bad logic. Actually, the fact that global warming has not killed off polar bears as predicted means there are lots of bears to come ashore causing problems in late winter (while they wait for Arctic seal pups to be born, so they can eat them).

Polar bear myths perpetuate from the mouth of stuck-in-the-past Ian Stirling

In my last post, I complained about “vague and misleading statements” made by polar bear specialists and conservation advocates. Here’s a recent example of that phenomena, from veteran polar bear biologist Ian Stirling.

The magazine of Canada’s North, UpHere, published an interview with Ian Stirling this month. The piece begins:

“No fear-mongering. No exaggeration. For Ian Stirling, it’s purely about the science.”

Yeah, well – judge for yourself. Here’s a sample:

“We have lost on average about half the sea ice that we had in 1979, which is the first year that satellite coverage of the Arctic was taken [he’s talking about September ice here]. Places like Hudson Bay are breaking up three weeks earlier than they used to and freezing up a couple weeks later. We’re going to have even more significant effects over a much wider area in the Arctic. We’re likely to lose another 30 or 40 percent, or even half of the bears that we have today in the middle of the century, and unchecked, we will likely have very few bears left at the turn of the next century. In 2100, we’ll probably just have a few small remaining pockets in the northern Canadian Arctic islands and northern Greenland.”

Read the rest here.

Stirling’s opinion about polar bears and climate change hasn’t changed since at least 2004 despite the following scientific developments: Continue reading

Challenging polar bear fearmongering about Arctic sea ice extent for March 2015

Here are some facts to counter the misinformation and fearmongering being spread via twitter by a polar bear biologist who is getting carried away with his conservation activism.

Arctic Sea ice extent March greater than PB habitat_April 12 2015

Following up on my last post, I note that Arctic regions with sea ice but not polar bears were about 0.32 mkm2 below last year’s March average extent – which means the total ice decline from 2014 (0.4 mkm2) represents only a slight decline in polar bear habitat, most of which is in the Barents Sea (and due primarily to the state of the AMO, not global warming).

Sea ice extent for the Sea of Okhotsk and Baltic Sea combined (both areas without polar bears)1 were about 0.6 mkm2 below average this year for March. Average extent for March (according to NSIDC) is 15.5 mkm2, which means this year’s extent (14.4 mkm2) was 1.1 mkm2 below average, of which less than half (0.5 mkm2) was “lost” polar bear habitat.

IUCN Polar Bear Specialist Group biologist Andrew Derocher has been saying this is a “huge loss for polar bears” (see below): rational analysis of the facts show it is not. Continue reading
