Too bad so little of what Attenborough promotes is actually true and that he gets away with it because the message comes with pretty pictures. Except for the Russian falling walrus, of course: that film footage was so awful many people were truly horrified at what they were being shown. Death after gruesome death, all in slow motion, crafted to deliver the greatest shock possible, all falsely blamed on climate change by Attenborough.
Back in 2019, when the WWF/Netflix walrus sequence from ‘Our Planet’ was released, its purpose was to ensure the votes for unified action (i.e., ‘success’) at the upcoming UN climate meeting (COP26). Rather than “giving people hope” about taking action on climate change, that particular film footage was meant to emotionally bully politicians into action, as I explain in my latest book, Fallen Icon. Too bad it failed.
Posted onMay 17, 2022|Comments Off on Polynyas are critical for polar bear spring feeding
Areas of open water or thin ice in spring are essential for the survival of Arctic species, as I emphasized in my recent peer-reviewed paper on polar bear ecology. Sea ice is still abundant in spring (April-June), which is the critical feeding period for polar bears: they must consume about 2/3 of the total calories they need for the entire year. Most of those calories come from newborn seals (ringed, bearded, and harp).
In southern areas, such as Hudson Bay and Davis Strait, virtually all of this feeding is completed by the end of May, making June a time of opportunistic hunting for most bears: if they find a seal, they will kill and eat it but if not, they can do without. That’s not just my opinion but the reason given by polar bear specialists themselves to explain why Southern Hudson Bay polar bear numbers had not declined in the 2000s despite a sudden increase in the ice-free season:
…even though break-up has advanced by up to 3-4 weeks in portions of Hudson Bay it still occurs no earlier than late June or early July so does not yet interfere with opportunities to feed on neonate ringed seal pups that are born in March-April in eastern Hudson Bay. Therefore, losing days or weeks of hunting opportunities during June and July deprives polar bears of the opportunity to feed on adult seals, but does not deprive them of the critical spring period when they are truly hyperphagic. [Obbard et al. 2016:29]
Posted onMay 12, 2022|Comments Off on Wandering polar bears are the new starving bears falsely blamed on climate change: Déjà vu
I said last year that wandering polar bears appeared to be the new ‘starving’ polar bears that were formerly the go-to victims falsely blamed on lack of ice due to climate change and here we are again. Polar bear specialists and their cheer leaders so seldom disappoint.
Posted onMay 6, 2022|Comments Off on Ancient polar bear remains explained by sea ice and polynyas: my peer-reviewed paper
My open-access, peer-reviewed paper on the ecology of ancient polar bears in relation to sea ice has just been published in Open Quaternary. It’s called ‘Polar Bear Fossil and Archaeological Records from the Pleistocene and Holocene in Relation to Sea Ice Extent and Open Water Polynyas’.
A unique compilation of more than 104 polar bear skeletal records from the Holocene and late Pleistocene shows that most ancient remainsare associated with existing or ancient open water polynyas or the expansion of sea ice during past cold periods. This big-picture analysis indicates that as they do today, polar bears were most commonly found near polynyas throughout their known historical past because of their need for ice-edge habitats.
Read my longer summary below and download the paper here. This is a much-updated and expanded analysis based on an informal study I did in 2012.
Posted onMay 1, 2022|Comments Off on Fat polar bear killed on the south shore of the Gulf of St. Lawrence on the Gaspé Peninsula
A fat polar bear was killed early this morning (Sunday 1 May 2022) near a small town on the north shore of the Gaspé Peninsula, the portion of Quebec that New Brunswick in the Gulf of St. Lawrence after being tracked by wildlife conservation officers since yesterday. Two other sightings were reported in the Gulf earlier in April on the opposite shore, which could possibly have been the same bear.
These recent polar bear sightings in the Gulf of St. Lawrence likely reflect a population that’s at its peak size or still increasing. The photo above shows the bear was in excellent condition after feeding heavily on harp seal pups. Unfortunately, from where it ended up, it likely wouldn’t have made it back to the receding pack ice off Labrador in time to return to Davis Strait for the summer.
Excerpt below from the CBC story (‘Polar bear spotted on Gaspé peninsula killed by wildlife officers‘; 30 April 2022), but first you’ll need the map of the area. Charts for sea ice conditions at the time follow.
