New Study Finds A 79% Rise In Polar Bear Sightings Since 2005 As Their Arctic Habitat Dramatically Expands

Research on polar bear sightings using a systematic “regional marine mammal sightings programme” during 2005-2018 reveals there were 1,433 polar bears sightings from 2005-2011 compared to 2,569 during 2012-2018 around Svalbard.

The perspective that polar bears  are endangered by global warming because reduced sea ice limits their seal-hunting opportunities is  again contradicted by real-world observations.

New research (Bengtsson et al., 2021) suggests marine animals and polar bears have both been far more active and abundant in recent years compared to the past as their habitat expands around Svalbard. Not only have seal and walrus sightings risen by 50-100% since 2005, but polar bears were nearly 80% more likely to be spotted by observers during 2012-2018 when compared to sightings from 2012-2018.

The expanded range and rise in sightings should not be surprising.  Polar bears’ worst body condition – when they’re at their thinnest – occurs during the months of the year when sea ice is thick: April and May. Polar bears’ best, well-fed body condition occurs during the months when sea ice is at its thinnest, or after the seasonal ice break-up occurs: August to October (Galicia et al., 2020).

Other observational research (Bourque et al., 2020) shows polar bears were consuming no fewer seals in 2016 than they did in 2004, indicating the reduction in sea ice hasn’t limited polar bears’ feeding practices.

Empirical estimates have affirmed Chukchi Sea polar bear populations have been “productive in recent years” and their “body condition and reproduction…did not decline between 1986-1994 and 2008-2011” (Regehr et al., 2018).

Thriving polar bear populations have even become a problem for residents who share their geographical area. Inuit have for years reported there are too many polar bears in the Arctic now, and this consequently puts humans in danger.

But activist scientists – who don’t live in the region but who nonetheless think they know better – claim polar bears are endangered and their populations shrinking due to sea ice decline.

Political activism seems to have supplanted real-world scientific observation.

    Old joke: When Al Gore was born there were 5,000 polar bears. Now there are only 30,000.

    Susan Crockford believes there are likely 39,000.

    They will eat us all. We’re doomed.

    Modern techniques – rifles, aircraft, snowmobiles – were hard on Polar Bear populations. Did I mention trophy hunting?
    Anyway, with those things controlled, the world for Polar Bears is a better place.

    A person can spend a few good hours reading what Susan Crockford has to say.

    There is a great cartoon “by Josh” up on her site today (2/22).

    The polar bear climate change talking point is on the endangered list. Something has to be done to save it!

  5. Facebook ”faktagranskar” klimatinlägg - Klimatupplysningen

    […] Apropå faktagranskarnas påpekande om att isbjörnarna är hotade så har det precis kommit flera vetenskapliga undersökningar som tvärt om visar på en dramatisk ökning av antalet nallar kring Svalbard och att de klarar sig […]
