Nov 26th, 2018: Wrangel Island
Wrangel Island is Russian and looks like they’re a little unfriendly towards the neighbors.
But these are the neighbors. Quote:

Climate change advocates have said polar bear numbers would decline... they haven't, yet. Stories like this that say they can adapt to conditions, and possibly increase in numbers, are considered unhelpful to the cause.
Don't look now but Arctic ice conditions are stable for the last ten years. The 2018 graph of extent is about the same as the 2007 graph of extent. This doesn't mean there is no AGW. AGW is a proven phenomenon. The ice extent, and volume, are still maybe a tenth off what they were 25 years ago. The quicker melting caused a lot of scientists about a decade ago to claim the Arctic might be ice-free during summer by 2014. Not even close. That prediction was unhelpful. Predicting the future is very, very hard. Maybe this reflects "the pause", maybe always-changing ocean circulation, or maybe the question of what exactly melts the ice is more complex than just the global temperature anomaly. (Some people believe that Chinese soot is involved.) Also, more of the warming has been at the Arctic than anywhere else, but that may change as well. There wil be winners and losers out of global warming; and the polar bears are not yet found on one side or the other of that equation. They adapted to the last 25,000 years of (slower) warming so they may wind up just fine. Revisit this thread in 2040 for the update. |

Wrangal is a wildlife sanctuary where civilian natives have been moved off the island, and only a few Russian scientists/technicians are allowed to visit. Even they aren't allowed weapons other than pepper spray and tasers. So the huge increase in bears on Wrangel shouldn't be construed as representative of the Arctic bear health.
Another startling prediction I read in the last year is the change in sea ice and reduction in arctic ocean outflow of cold water will kill the Gulf stream, causing the British Isles and parts of western Europe to become a lot colder. I always suspect this sort of thing is hyperbole by the reporter to pump a headline from a scientific report. But it certainly sticks in my subconscious even though it won't affect me.

If there are fewer places for bears to go because there is less ice, some locations will have an increase in the number of bears per square kilometre while others will have a decrease. Overall the numbers could decrease and still get local increases.

Same windows?

No, those are in neat rows. Might be the same island though.

The entire world is kind of a polar bear sanctuary: it's currently illegal for anyone but indigenous peoples to hunt polar bears, anywhere on the planet.
Local changes don't tell us much about global changes. I believe that the 1930s, dust bowl years, remains the warmest decade for the contiguous US. |

I suspect the lemmings outnumber the bears. In lemming years, anyway.

I suspect several bird species do too. Plus, musk oxen are herd animals; if there are more apex predators than musk oxen, it seems to me that something's seriously broken in the ecosystem.

The bears are tourists, not residents. They're like human tourists who outnumber natives (in season) at a shitload of touristy destinations. But it's not that big an island so less than 700 Musk Oxen is quite probable.

I guess a t-shirt would be asking for too much...

Isn't polar bears adapting to global warming just putting electrical tape over the check engine light?

True in some senses. The polar bears don't give a shit. It's like, some species will actually benefit, just like some areas may wind up colder due to changes in ocean currents and whatnot. These variations will drive people nuts as they try to work out what is actually going on. I'm trusting the satellites.
