A recent Netflix ‘Our Planet’ program with David Attenborough delivering a disturbing message of doom about walruses falling off a cliff to their deaths because of climate change is contrived nonsense on par with the bogus National Geographic starving polar bear video of 2017. The walruses shown in this Netflix film were almost certainly driven over the cliff by polar bears during a well-publicized incident in 2017, not because they were “confused by a combination of shrinking ice cover and their own poor eyesight“.
Apologies for neglecting to add, h/t to Charles the Moderator from WUWT!
UPDATE 8 April 2019: Falling off cliffs is not a new phenomenon. Here is video of US Fish and Wildlife officials in 1994 trying to explain a situation where walruses are falling even without the impetus from polar bears, at Cape Pierce in the southern Bering Sea (a haulout for adult males during the ice-free season). Explanation? Overcrowding (too many walruses)! h/t to Mark Sullivan.
Also, see this 8 April 2019 piece from The Atlantic that confirms the ‘Our Planet’ footage was filmed in 2017, and that “the sequence includes footage from two separate beaches—one with the 100,000-strong congregation and one with the falls.”
UPDATE 9 April 2019: For the details on why the two events described below (the one filmed by Attenborough’s ‘Our Planet’ crew and the event reported by the Siberian Times in 2017) are almost certainly one and the same, see Andrew Montford’s post at The Spectator. The Global Warming Policy Foundation has issued a press release.
UPDATE 14 April 2019: New details show that the film crew are still lying about the walrus death event in the Netflix ‘Our Planet’ episode, summarized by me here.
