From Polar Bear Science
A polar bear bit the hand of a member of a film crew near the Danish military base of Daneborg in East Greenland on Monday (2 August) and predictably, this has been blamed on recent warm temperatures in the region. There is no specific evidence of cause and effect, of course. The news outlet reporting the incident cites some non-specified ‘experts’ as providing the generic ‘warming makes polar bears starve or behave badly’ excuse that makes no sense in this particular instance.
Here is what the news report had to say (3 Aug), my emphasis:
Early on Monday, while the sun does not set in summer at this latitude, the bear poked his head through a poorly closed window of a research station where the documentary team was staying about 400 metres from the small base of Daneborg.
A Danish Arctic military unit based in Greenland said the bear bit the hand of one of the three male team members before they used warning pistols to force the animal to flee.
Transported first to Daneborg, the injured documentary maker had to be evacuated to Akureyri, a town in Iceland.
Already blamed for five incidents until now, the bear returned again later in the morning and then again overnight Monday to Tuesday when it broke a window of the research station before fleeing.
“The local authorities have from now on categorised the bear as ‘problematic,’ which allows for it to be shot dead, if it returns,” the Danish military unit said.
Daneborg is marked on the map below:
Any bear causing problems in this region would have just come off the ice, since three weeks ago there was plenty of ice available offshore a bit to the north (see chart below for 7 July). Virtually all bears are at their best condition at this time of year, except for young, inexperienced bears or those that are sick or injured. Warm temperatures would not be causing any bear to be desperately looking for food unless it was desperate for some other reason (sick, injured, or an under-nourished young bear). However, nothing is stated in this report about the physical condition of the bear, its approximate age or its sex, even though it has been seen multiple times. Young male bears, for example, are far more likely to become problems near communities than any other age class (Wilder et al. 2017), because these bears have to compete with older, larger bears to keep whatever seals they manage to kill.
Note the reliance on un-named ‘experts’ at the end of the same news report:
Experts say the retreat of the ice pack, the hunting ground of the polar bear, forces them to stay on land more often and they find it harder to find food and sustain a species already considered vulnerable.
Although still rare, the close encounters with humans are increasing as bears more frequently approach inhabited areas in their search for food, environmental protection officers say.
What generic pap! The community has a problem bear on its hands, a situation which northern communities across the Arctic must contend with on a continual basis. Even if there was ice offshore, there would be the possibility of bears coming ashore and causing problems.
There is also the issue no one wants to talk about because it has nothing to do with declining sea ice: with more bears comes more problem bears.
