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.]

Sea ice development in eastern Svalbard this fall is lagging well behind the rest of the Arctic. Several polar bear researchers (e.g., Andrew Derocher here and here) have recently been raising the alarm that this might be devastating for Barents Sea females looking for suitable denning sites.
The implication is that pregnant polar bear females are inflexible – so fixated on one location to give birth that they are unable or unwilling to choose an alternative if conditions preclude using their preferred location this year. However, the available facts do not support such a pessimistic attitude.
