Late fall polar bear habitat 2020 compared to some previous years

It’s time to look at sea ice habitat at 15 December (Julian Day 350), now that virtually all bears except pregnant females throughout the Arctic are either out on the sea ice attempting to hunt for seals or hunkered down … Continue reading

Polar bears again attracted to Russian town by dead walrus Attenborough blames on no sea ice

In the news again: Cape Schmidt (on the Chukchi Sea) made famous by Sir David Attenborough’s false claim that walrus fell to their deaths because of lack of sea ice due to climate change when a clever polar bear hunting … Continue reading

The conundrum of Hudson Bay bears that left shore late in 1983 with video from CBC archives

In 1983, it was claimed that freeze-up of Hudson Bay was so late that polar bears didn’t leave the shore until the 4th of December – several weeks later than had been usual at that time. However, the fact that … Continue reading

Polar bear habitat update for late November

Sea ice formation is ahead of usual in some regions and behind in others but overall, sea ice habitat is abundant enough for this time of year for virtually all polar bears across the Arctic to be back out on … Continue reading

Strange sea ice pattern over Hudson Bay as winds blow polar bears offshore

Winds blew a huge mass of new shorefast sea ice way out into Western Hudson Bay a few days ago (13 November) and very likely took some polar bears with it. This offshore wind phenomenon is common at this time … Continue reading

Shorefast ice formation and the fall feeding season for polar bears

What may seem like a silly question is actually fundamental to polar bear survival: in the fall, why do Western Hudson Bay bears correctly expect to find seals in the new ice that forms offshore? Why are seals attracted to … Continue reading

Western & Southern Hudson Bay polar bears experience earliest freeze-up in decades

This is shaping up to be one of the shortest ice-free seasons in at least 20 years for both Western and Southern Hudson Bay polar bears. Last week, sea ice started forming along the shore of Hudson Bay, from the … Continue reading

Polar bear research on hold in Western Hudson Bay due to COVID-19 restrictions

After spring polar bear research was cancelled in Western Hudson Bay (and pretty much everywhere else) this year because of Covid 19 concerns, it now transpires that fall research is out as well. Travel restrictions implemented by government departments and … Continue reading

S. Beaufort polar bear population stable since 2010 not declining new report reveals

A just-released report on the latest count for the Alaska portion of the Southern Beaufort subpopulation reveals that numbers have been stable since 2010 despite claims the population has continued to decline. However, the study also has a very odd … Continue reading

Potential impact of the second-lowest sea ice minimum since 1979 on polar bear survival

The annual summer sea ice minimum in the Arctic has been reached and while the precise extent has not yet been officially determined, it’s clear this will be the ‘second lowest’ minimum (after 2012) since 1979. However, as there is … Continue reading
