You're joking, right?

As the world warms and Arctic sea ice thins, starving polar bears are being driven ever further south,

IF the Arctic was actuall warming, wouldn't the polar bears be driven farther north looking for colder weather with MORE sea ice? No, says these "scientists". The ice has thinned so they are driven south where there is no ice. Got it.

Stop being so gullible!!!

You don't think that polars simply evolved into the eternally cold environment of the Arctic? You think that all moraines had to be buried under ice at the same time, and if a sufficiently large area is buried under ice, polar bears will sprout out of the snow? Is that how it works?

... but outside of the widespread ice, the effect is for brown bears to sprout out of the dirt? Is that how it works?

In 2006, the occurrence of this hybrid in nature was confirmed by testing the DNA of a unique-looking bear that had been shot near Sachs Harbour, Northwest Territories, on Banks Island in the Canadian Arctic.

Have you looked at a map, GasGuzzler??? There looks to be dozens or hundreds of islands in that area of the Arctic Sea.

Perfect place for polar bears to migrate south. Lots of sea and lots of land. Makes sense once they reach the Canadian mainland, they would meet their grizzly mates.

Did your eyes just glaze over when you read the part about the warming causing the thinning causing the starving?

Would this not suggest colder yields more ice which yields more food which yields more polar bears?

Dude, the entire story is hooey. Polar bear numbers are soaring. Apparently they are also horny as hell.

The fact is that brown bears and polar bears were once the same bear that was separated over a large area by ice. The brown bears stayed invisible in the woods at night and selective adaptation turned the also brown bears white as that is the only color of ice and snow. This is common knowledge

When did polar bears evolve from brown bears?

150,000 years ago

Evolutionary studies suggest that polar bears evolved from brown bears during the ice ages. The oldest polar bear fossil, a jaw bone found in Svalbard, is dated at about 110,000 to 130,000 years old. DNA comparisons suggest the species may have split at least 150,000 years ago, and maybe longer.

So, these bears have lived on ice for thousands of years, but suddenly they must have solid footing and are now actively seeking solid ground? Please explain.

Do you really not understand? Since observations clearly indicate Arctic ice has been declining, looks like some polar bears have been forced to move south, hopping from island to island in the Arctic sea, throughout Northwest Territories, Yukon, and Nunavut, in search of more solid footing.

How Grizzlies Evolved into Polar Bears
June 10, 2008

The icon of the Arctic, the polar bear, is the ultimate survivor in one of the harshest areas on Earth. Reigning over a world of ice, tundra, and snow, this carnivore would seem to have a lineage that traces back to some mammoth creature of the icy regions.

But in fact, the polar bear's closest ancestor is a land carnivore we associate more strongly with our forests. Over the years, scientists have uncovered an evolutionary path suggesting that polar bears are a relatively new species, and actually a subspecies, of Ursus arctos, more widely known as the brown bear. Scientific evidence has found that the brown bear, a species that also includes grizzly bears, was a "precursor" to polar bears, which then went on to develop specializations for inhabiting the harsh Arctic.

Proving their genetic compatibility, brown bears and polar bears can mate and produce viable, or fertile, offspring. It is this reproductive viability that establishes that an animal belongs within a given species. In 2006, a hybrid grizzly/polar bear, which some call a "pizzly," was discovered in the Canadian Arctic, providing researchers proof that polar bears and grizzly bears can interbreed, even in the wild. And when researchers in Alaska compared the DNA of brown bears from around the world, looking for genetic links, they made an interesting discovery about one population of brown bears in particular. Analysis of the DNA of a distinct population of brown bears living on Alaska's ABC islands, 900 miles south of the nearest polar bear, revealed that the ABC bears were even more closely related to polar bears genetically than they were to other brown bears.

So just when did polar bears arise as a separate subspecies? Genetic models show that the emergence of the polar bear could have taken place as recently as 70,000 years ago or as many as 1.5 million years ago. For many years, a fossil found at Kew Bridge in London was considered the oldest polar bear specimen. The fossil then placed the evolution around 70,000 years ago. But recently, scientists uncovered a fossilized jawbone from an island in the Arctic Ocean midway between Norway and the North Pole, dated to be at least 100,000 years old. Scientists believe this jawbone may represent the remains of the oldest-known polar bear, thus marking the appearance of the polar bear earlier than previously thought.

Relying on the fossil record and DNA analysis, scientists have been able to arrive at a clearer picture of the polar bear's evolutionary path over the millennia. Some 200,000 years ago, when glaciers covered much of Eurasia, the Arctic Ocean was completely frozen. It was during this challenging period that brown bears began to wander in search of food. Approximately 125,000 years ago a population of brown bears in the far north of their range was likely split off from their brown bear ancestors, perhaps because of competition for food. The population likely became isolated by massive glaciers and, while most died in the harsh environment, those bears with an evolutionary advantage — ideal coat color and thickness for extreme cold — survived and bred. Over thousands of years, this population of bears underwent further evolutionary change, adapting even more specialized traits for surviving the harsh polar environment. When life in the North demanded teeth better shaped for ripping apart seals than munching berries, the polar bear's molar teeth changed significantly from those of the brown bear. The bears also grew white fur, which camouflaged them in their snow-covered surroundings and gave them a hunting advantage. Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new subspecies of bear — Ursus maritimus or the polar bear.

Nature once exerted such extreme pressure on the brown bear that it eventually gave rise to a new, better-adapted subspecies, the polar bear. Now, once again, evolutionary forces are acting on this long-enduring species. As the Arctic warms, the polar bear's unique specializations that once lent it an evolutionary edge, may now be the creature's downfall. A changing climate may name a new king of the Arctic — the fierce and opportunistic brown bear.

Nope. I don't understand how they are starving because it's warmer, so they go "island hopping" to someplace warmer.

Try to use your imagination for something other than insults, would you?

The polar bears stomping grounds: polar ice, is shrinking.

Hence, some must find new stomping grounds, that doesn't melt, on those many little Arctic islands, in the Great Canadian North, where there is still plenty of sea for them to hunt. Eventually one or more of them makes it all the way to the mainland continent and meets a grizzly.

They fall in love and make a pizzly. The end.

Interesting concept: the invisible brown bear. It's like saying the invisible pink unicorn. If it's invisible, how do you know it's brown, or pink, or burnt umbar?

Only if you round up. I was there. It happened 144,262 years and 73 days ago. I'd tell you the number of hours and minutes but I don't know when you'll be reading this post.

Boy, it's a good thing we are omniscient with time machines, making all of this common knowledge and not WILD SPECULATION.

A very good thing indeed.

Swan wrote:Evolutionary studies suggest ...

Obviously we don't need any "studies" when we just know it all. It's common knowledge! Almost too common. When I was walking with my buddy downtown and I blurted out "Damn! I forgot when brown bears evolved into polar bears" ... the hooker standing behind me didn't even remove the cigarette from her lips when she shouted out "Dude, it happened 144,262 years and 73 days ago." I got her good by asking her "How many hours and minutes?" ... and making her think ... but she got it right. It was good for a laugh.

Swan wrote:... that polar bears evolved from brown bears during the ice ages.

So if there weren't any ice ages, and all those moraines were under ice at different times, ... then your speculation falls apart.

Too funny.

Swan wrote: DNA comparisons suggest the species may have split at least 150,000 years ago, and maybe longer.

I'm sure that we can be absolutely certain of the efficacy of these DNA comparisons ... because DNA comes with metadata tags with clear timestamps for each mutation. We can simply list it all as "what we know."

I was assuming you understood: Polar bears live in the Arctic, on ice-covered waters. Polar bears rely on sea ice to access the seals that are their primary source of food, as well as to rest and breed.

Now if the ice has shrunk, there is less habitat for the polar bears.

Since polar bears are viciously territorial, the shrinking of their habitat forced some of them away.

A good path for them to migrate, where they are likely to find hunting territory, is the many small islands in the Arctic sea, in the far north Canadian territories.

Clearly one or more of them made their way far enough South along this path, where grizzlies roam.

I'm sure that we can be absolutely certain of the efficacy of these DNA comparisons ... because DNA comes with metadata tags with clear timestamps for each mutation. We can simply list it all as "what we know."

You quote each phrase that I say because this has meaning to you, unfortunately no one else on this Earth shares in your delusions. Again the polar bear was once a brown bear, it lost it's color when it was separated by glaciation and had to become camouflaged in an environment of snow and ice. This is how adaptation happens, that said this is impossible for you because you can not accept that the climate ever changes.

Correct brown bears can not live on the ice because they need to hibernate and sea ice is not suitable for this since it moves and the bear would be crushed, so they seek out caves on the land

In 2006, the occurrence of this hybrid in nature was confirmed by testing the DNA of a unique-looking bear that had been shot near Sachs Harbour, Northwest Territories, on Banks Island in the Canadian Arctic.

Have you looked at a map, GasGuzzler??? There looks to be dozens or hundreds of islands in that area of the Arctic Sea.

Perfect place for polar bears to migrate south. Lots of sea and lots of land. Makes sense once they reach the Canadian mainland, they would meet their grizzly mates.


Did your eyes just glaze over when you read the part about the warming causing the thinning causing the starving?

Would this not suggest colder yields more ice which yields more food which yields more polar bears?

Dude, the entire story is hooey. Polar bear numbers are soaring. Apparently they are also horny as hell.


The bears are obviously moving further south, probably to find more solid footing. The paternity test doesn't lie.

Speaking of eyes glazing over, Swan is babbling something that you can be certain is a lie.

How Grizzlies Evolved into Polar Bears
June 10, 2008

The icon of the Arctic, the polar bear, is the ultimate survivor in one of the harshest areas on Earth. Reigning over a world of ice, tundra, and snow, this carnivore would seem to have a lineage that traces back to some mammoth creature of the icy regions.

But in fact, the polar bear's closest ancestor is a land carnivore we associate more strongly with our forests. Over the years, scientists have uncovered an evolutionary path suggesting that polar bears are a relatively new species, and actually a subspecies, of Ursus arctos, more widely known as the brown bear. Scientific evidence has found that the brown bear, a species that also includes grizzly bears, was a "precursor" to polar bears, which then went on to develop specializations for inhabiting the harsh Arctic.

Proving their genetic compatibility, brown bears and polar bears can mate and produce viable, or fertile, offspring. It is this reproductive viability that establishes that an animal belongs within a given species. In 2006, a hybrid grizzly/polar bear, which some call a "pizzly," was discovered in the Canadian Arctic, providing researchers proof that polar bears and grizzly bears can interbreed, even in the wild. And when researchers in Alaska compared the DNA of brown bears from around the world, looking for genetic links, they made an interesting discovery about one population of brown bears in particular. Analysis of the DNA of a distinct population of brown bears living on Alaska's ABC islands, 900 miles south of the nearest polar bear, revealed that the ABC bears were even more closely related to polar bears genetically than they were to other brown bears.

So just when did polar bears arise as a separate subspecies? Genetic models show that the emergence of the polar bear could have taken place as recently as 70,000 years ago or as many as 1.5 million years ago. For many years, a fossil found at Kew Bridge in London was considered the oldest polar bear specimen. The fossil then placed the evolution around 70,000 years ago. But recently, scientists uncovered a fossilized jawbone from an island in the Arctic Ocean midway between Norway and the North Pole, dated to be at least 100,000 years old. Scientists believe this jawbone may represent the remains of the oldest-known polar bear, thus marking the appearance of the polar bear earlier than previously thought.

Relying on the fossil record and DNA analysis, scientists have been able to arrive at a clearer picture of the polar bear's evolutionary path over the millennia. Some 200,000 years ago, when glaciers covered much of Eurasia, the Arctic Ocean was completely frozen. It was during this challenging period that brown bears began to wander in search of food. Approximately 125,000 years ago a population of brown bears in the far north of their range was likely split off from their brown bear ancestors, perhaps because of competition for food. The population likely became isolated by massive glaciers and, while most died in the harsh environment, those bears with an evolutionary advantage — ideal coat color and thickness for extreme cold — survived and bred. Over thousands of years, this population of bears underwent further evolutionary change, adapting even more specialized traits for surviving the harsh polar environment. When life in the North demanded teeth better shaped for ripping apart seals than munching berries, the polar bear's molar teeth changed significantly from those of the brown bear. The bears also grew white fur, which camouflaged them in their snow-covered surroundings and gave them a hunting advantage. Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new subspecies of bear — Ursus maritimus or the polar bear.

Nature once exerted such extreme pressure on the brown bear that it eventually gave rise to a new, better-adapted subspecies, the polar bear. Now, once again, evolutionary forces are acting on this long-enduring species. As the Arctic warms, the polar bear's unique specializations that once lent it an evolutionary edge, may now be the creature's downfall. A changing climate may name a new king of the Arctic — the fierce and opportunistic brown bear.

If you could handle the truth, you would

Nope. I don't understand how they are starving because it's warmer, so they go "island hopping" to someplace warmer.

Now you have polar bears starving because ice is melting and they are seeking perfect stomping grounds and it is land, not ice. I'm so confused. If the ice melts, then they have land. Why migrate?


I was assuming you understood: Polar bears live in the Arctic, on ice-covered waters. Polar bears rely on sea ice to access the seals that are their primary source of food, as well as to rest and breed.

Now if the ice has shrunk, there is less habitat for the polar bears.

Since polar bears are viciously territorial, the shrinking of their habitat forced some of them away.

A good path for them to migrate, where they are likely to find hunting territory, is the many small islands in the Arctic sea, in the far north Canadian territories.

Clearly one or more of them made their way far enough South along this path, where grizzlies roam.
Whataboutism.

Yes, absolutely. I was just having difficulty finding images of hibernating polar bears. Smart photographers avoid burrowing into polar bear snow to get good pics.



One thing to watch for is the latest effort afoot, which I can only presume is part of the Marxist propaganda machinery in support of Global Warming and Climate Change, which is the rather boldfaced claim that polar bears do not hibernate like other bears. The claim is that polar bears instead seek a snow cave and enter a period of total inactivity for four to eight months.

RECAP: Polar bears don't hibernate; they do something else that looks very similar but that we insist is not hibernation.

RECAP: Our religion isn't a religion; it is something else that looks very similar to religion but is atheism that we insist is settled science.

RECAP: Greenhouse Effect doesn't violate physics; it simply creates additional energy through greenhouse gas re-radiation and by increasing earth's average temperature by reducing its radiance.

RECAP: Facemasks are not ineffective against COVID; the size of the holes in a facemask, as well as the rapid evaporation of breath moisture, may make it appear that facemasks are impotent against 120nm viruses, but we insist that "my facemask and six feet protect you, and your facemask and six feet protect me."

Indeed grizzly bears aren't encroaching on polar bear territory, it is the other way around.

What about those polar bears you mentioned, nowhere near the Canadian archipelago? Those are the ones who won the battle over territory when polar ice habitat shrunk. The polar bears migrating to the Canadian archipelago were the ones who lost the battle when habitat shrunk, and left to find new hunting area.

Yes, if your habitat requires ice, and a shitload of it, definitely go somewhere warmer if it has become too warm to sustain ice. Can we add this to what we know?
