Today’s the day to celebrate the resilience and adaptability of polar bears.
Not only did the record-breaking sea ice low of 2012 have virtually no effect on the bears but in 2014, only two subpopulations were classified as “declining” or “likely declining” – down from seven in 2010 and four in 2013 (see map below).
See my recent “Twenty good reasons not to worry about polar bears.”

POLAR BEARS IN THE NEWS…
Kudos to the CBC for producing a propaganda-free polar bear “Fun Facts” page for kids that won’t give them nightmares – have a look.
Other news: Polar bears come early to Black Tickle, Labrador this year, a new population count is planned for the Barents Sea subpopulation, and The Times (UK) publishes some good news about polar bears. Details below.
UPDATE February 27, 2015. I’ve added another news item I missed below.

Produced by the Global Warming Policy Foundation, there is now a short video summary of my recently-released GWPF briefing paper, which I wrote and narrated.
Watch it below:

I’ve written a briefing paper for the GWPF refuting claims that huge herds of Pacific walruses hauled out on land are a sign of global warming.
Here’s the GWPF press release:
London, 20 October: A briefing paper published today by the Global Warming Policy Foundation refutes claims that Arctic walruses are in distress and danger due to global warming.
The paper, written by Canadian zoologist Dr Susan Crockford, assesses the recent mass haulouts of walrus females and calves on the beaches of Alaska and Russia bordering the Chukchi Sea. The events have been blamed by US government biologists and WWF activists on lack of summer sea ice, amplified into alarming scare stories by news media around the world.
Such claims ignore previous haulouts that suggest a different cause. Scientific reports about large walrus haulouts that have occurred repeatedly over the last 45 years show that they are not new phenomena for this region.
At least two documented incidents of similar magnitude have occurred in the recent past: one in 1978, on eastern St. Lawrence Island and the other in 1972, on the western end of Wrangel Island. The 1978 event involved an estimated total of almost 150,000 walrus hauled out within in a small geographic area.
Moreover, sea ice maps for the months when known mass haulouts occurred, compared to years when they did not, suggest no strong correlation with low sea ice levels.
“The WWF and American walrus biologists have categorically linked the Point Lay mass haulout event to global warming, but available evidence suggests that’s alarmist nonsense,” Dr Crockford said.
“Blaming lack of sea ice for recent events ignores the documented factor – large population size – that drove walruses onto beaches en masse in the past, when plenty of ice was available. Conservation measures have almost certainly led to a spectacular recovery of walrus numbers over the last few years. This suggests that recent mass haulouts are more an indicator that Chukchi walrus are nearing maximum capacity than a sign of impending global warming catastrophe,” Dr Crockford added.
Here’s the paper. [Link fixed, h/t HO]
