Last week I asked: “What’s causing the death of the polar bear as a climate change icon?”
I was echoing the conclusion of a commentator at the Arctic Institute (22 August 2017) who lamented: “The polar bear is dead, long live the polar bear” and climate scientist Michael Mann, who told a lecture audience a few months ago that polar bears are no longer useful for generating “action” on climate change.
Now here’s the video. Watch “The Death of a Climate Icon” (31 August 2017):
The video was made possible with the assistance of the Global Warming Policy Foundation.
Kind of makes you wonder: is Al Gore’s recent climate change movie, An Inconvenient Sequel: Truth to Power, tanking at the box office because he couldn’t include polar bears as an example of the effects of human-caused global warming as he did in his award-winning 2007 effort? Did too many polar bears doom Gore’s 2017 movie?
Conclusions in the video about the predictions of polar bear decline vs. the current status of polar bears and sea ice are documented in my 2017 published paper:
Crockford, S.J. 2017. Testing the hypothesis that routine sea ice coverage of 3-5 mkm2 results in a greater than 30% decline in population size of polar bears (Ursus maritimus). PeerJ Preprints 19 January 2017. Doi: 10.7287/peerj.preprints.2737v1 Open access. https://peerj.com/preprints/2737/
