I think I saw playful behavior between species documented in the wild as well - as long as they weren't hunter and prey or direct rivals for the same food.
Bright ice, how can you crack and fail? How can the ice that seemed so mighty suddenly seem so frail?

Polar Bears are not what they used to be:


Thanks for that most interesting link Espen, which eventually took me to a more recent Polar bear video. If you edit out the 's' at the end of https in the link YouTube provides the video will embed itself. A bit like this:

Polar Bears are not what they used to be:

https://www.youtube.com/watch?v=JE-Nyt4Bmi8

The key observation to make here is that the bears in the video are in excellent condition. Grizzly bears in coastal Alaska and British Columbia can also be extremely tolerant of other bears and human observers when they are well-fed on abundant salmon. Aggressive predatory behavior increases drastically with hunger and reduced resources.

I think Magma is saying that the bears are often nice so long as they're not hungry, so it's hard to say from (just) this video that they're in trouble.

since the picture is more than 8 years old, still not sure what it means... and it might be older than that. I remember reading the original article back then, it was about the psychology of how animals recognize a "play attitude"

[just to be clear, I was referring to the earlier post, not the most recent one... my laptop hadn't loaded the recent one, apparently it's a bit slow...]

I recognise that the article is dated the 24th, but I don't recall seeing that much bare rock in NW Greenland this year. It's no biggy, but I check Flade Isblink on a daily basis & that picture, with the expanse of bare rock while Independence Fjord is frozen was unusual, to say the least.

Ok, reading the blurb, it's not from Aug. 24th. It's from July 16th, 2015. Or so it says...

As the northern hemisphere experiences the heat of summer, ice moves and melts in the Arctic waters and the far northern lands surrounding it. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image of sea ice off Greenland on July 16, 2015.

Large chunks of melting sea ice can be seen in the sea ice off the coast, and to the south spirals of ice have been shaped by the winds and currents that move across the Greenland Sea. Along the Greenland coast, cold, fresh melt water from the glaciers flows out to the sea, as do newly calved icebergs. Frigid air from interior Greenland pushes the ice away from the shoreline, and the mixing of cold water and air allows some sea ice to be sustained even at the height of summer.

According to observations from satellites, 2015 is on track to be another low year for arctic summer sea ice cover. The past ten years have included nine of the lowest ice extents on record. The annual minimum typically occurs in late August or early September. The amount of Arctic sea ice cover has been dropping as global temperatures rise. The Arctic is two to three times more sensitive to temperature changes as the Earth as a whole.

I double-checked using Aqua on Worldview, and it seems to check out (att).

If you zoom in to the quickly receding calving front at Zachariae Isstrom you can verify that the image is from this year...

To be fair, you can't tell about climate from a single bear. There have always been sick and old polar bears.

(Yes, I'm very worried about human-caused climate change. There is plenty of evidence. It's just that this is not it.)

Care of Climate Reanalyzer - This I think is a remarkable image.  It's Arctic temperature anomalies predicted about 42 hours out.

Most of Atlantic side of the arctic, from 90E to 90W, all the way from the pole to Iceland is red.

Dayum.  2-4KM wide?  Probably close to 500M deep.

That's the best part of a 1000KM long, I'll wager.

[edit: reevaluation - probably not that deep, but still, very old, probably fairly thick ice breaking off the shelf]

Beaufort captured on Worldview, using brightness temperature band 31-night, with the palette compressed to -50 to 0C.  Darker is colder.

Note the streams of higher temperature being swept clockwise to the west carried along by the flow around the high pressure currently over the arctic.
