Posted onJuly 13, 2022|Comments Off on Arctic sea ice is constantly changing which means polar bears must be flexible in their requirements
In honour of upcoming ‘Arctic Sea Ice Day’ (15 July), I revisit my 2015 essay on sea ice stability and polar bears, called The Arctic Fallacy. It challenges the flawed and out-dated ecological concept that under natural conditions, sea ice provides a stable and predictable habitat for polar bears, walrus and seals. The wide-spread adoption of this fallacy has allowed the present-day doom and gloom attitude of most Arctic specialists to develop.
[Polar Bears International have declared July 15 to be ‘Arctic Sea Ice Day’ to further its propaganda efforts to ‘save our sea ice’, which they claim is disappearing at an alarming rate due to global warming.]
Posted onJune 19, 2022|Comments Off on New polar bear subpopulation update: more background facts and details from the paper
Here are the facts you need to put into context the claim that the estimated 234 polar bears recently discovered in SE Greenland have been living ‘without sea ice‘.
The unique genetic isolation of this new subpopulation makes it one of the most interesting discoveries about polar bears we’ve seen in decades, yet the media were primed by a press release loaded with dooms-day climate rhetoric to focus exclusively on the model-predicted precarious future of the species, like this gem from the lead author:
“In a sense, these bears provide a glimpse into how Greenland’s bears may fare under future climate scenarios,” Laidre said. “The sea ice conditions in Southeast Greenland today resemble what’s predicted for Northeast Greenland by late this century.”
As a consequence, the media have been trying to out-do each other with the most over-the-top climate catastrophe headlines, see here and here. The authors of paper itself and a companion piece do the same: instead of focusing on the exciting scientific implications of the genetically isolated population they discovered, they promote the preferred narrative that polar bears have a bleak future and lecture the public (yet again) about the need for limiting CO2 emissions (Laidre et al. 2022; Peacock 2022).
