 'Something has changed:' Three bear species found in same northern Manitoba spotEnvironmental | 207724 hits | Nov 21 10:57 pm | Posted by: Hyack  Doug Clark of the University of Saskatchewan says he's got the first recorded proof of grizzly, black and polar bears all using the same land. "Scientifically, it has never been documented anywhere," he told The Canadian Press.Commentsview comments in forum Page 1 You need to be a member of CKA and be logged into the site, to comment on news. |

Simple solution. Earth wobbles, earth's magnetic field gets f'd up. Bears navigate by using the earths magnetic field, bears get screwed up and end up in the wrong place at the right time.
These guys are likely onto something but nobody's gonna listen to them because they don't hold a masters degree in environmental or animal studies.

No, nobody is going to listen to them because; it's a Wordpress Blog, and because NASA and the ESA monitor the magnetic field all the time and has found no 'wobble'.

Well, if they found no wobble they'd better pass that info along to these guys.
Scientists have long known that the axis on which the planet spins is prone to wavering, but some of the reasons have escaped understanding.
But researchers at NASA’s Jet Propulsion Laboratory say droughts and heavy periods of rain in different places around the planet are causing Earth to shake in space.
“We are going through this massive global-scale climate change, to such a degree that the change in climate has been strong enough to affect the rotation of such a giant planet,” said study co-author Surendra Adhikari of NASA’s Jet Propulsion Laboratory in Pasadena, California.
Since 2000, the Earth’s axis has jumped eastward by about 7 inches a year, a “massive swing,” Adhikari said. Another pattern of wobbling that occurs every six to 14 years has been vexing scientists for more than a century. The researchers examined both in their study.
The movements of the Earth’s axis are crucial to understand, since they affect the performance of satellites and global positioning systems. The polar axis also could become a powerful indicator for scientists studying climate change, Adhikari said.
The team published its findings Friday in the peer-reviewed open access journal Science Advances.
Scientists have thought the melting and forming of ice sheets around the world changed the distribution of mass around the planet enough to shift the polar axis.
And indeed they do, Adhikari said. The Greenland and Antarctic ice sheets are responsible for most of the force pulling and pushing the polar axis.
But Adhikari and Erik Ivins, both researchers at NASA’s Jet Propulsion Laboratory, charted the maximum impact these kinds of changes could have on the movement of the axis and determined there had to be some other force at work.
Examining images from the GRACE satellite, Adhikari and Ivins found that changes in the amount of water on land corresponds to the shifts in the axis. Just as ice piling up adds mass to an area, so does water accumulating in lakes, reservoirs, or aquifers, pushing the axis away from an area.
And as continents dry out during periods without water, they lose mass, which pulls the axis toward them.
“Imagine we have a perfect sphere that is rotating on an axis,” Adhikari said. “If you remove a chunk of material from any location of that idealized sphere, then you are perturbing the system, and the axis tends to head toward the location where you lose the mass.”
Effects from droughts or wet seasons are responsible for about 25 percent to 30 percent of the force pushing and pulling the polar axis. The movement is small — a few inches a year — but it can have serious effects.
“This delicate motion of the pole has to be taken into account to get accurate results from GPS, for example,” Adhikari said.

And these guys because they quite obviously didn't get the memo either.

Once again we have what some people would call, scientific consensus.
So, like I said, I'll believe the man in the field rather or in this case tundra rather than the one sitting in some lab counting his grant money.
But even if the wobble isn't affecting the earths magnetic field something is causing it to change and that could be screwing up the animals.

Couldn’t climate change be a factor as well? Polar bears are the least adaptable of these species in terms of diet. They may be in for a rough time.
Don't know. There needs to be a lot more data to be able to theorize a cause.
Well, if they found no wobble they'd better pass that info along to these guys.
You know that land mass and the magnetic field are different things, right? You are attributing the effect of one on the other, then dismissing both because they don't match.
And these guys because they quite obviously didn't get the memo either.

Once again we have what some people would call, scientific consensus.
Again, why would there be any theory, when there is no data? You cite a blog for knowing a cause, but not showing any relationship with any data. That's the way science works; first we gather data, then we postulate a theory that explains the data, and test the theory to see if it explains future observations.
So you post some Innu who say bears follow magnetic fields, and the fields are changing so the bears are moving. But where is the data that the bears even follow fields? You cite how the Earths' magnetic field changes, but where is the relationship to the bears? Is this based on tribal historical stories? If so, how do they know about magnetic fields?
So, like I said, I'll believe the man in the field rather or in this case tundra rather than the one sitting in some lab counting his grant money.
I've come to the conclusion that your distrust of science is because you misunderstand how it works. Do you understand that these pictures of bears are taken by the 'lab guys' who most certainly are not in a lab but 'in the field'?
But even if the wobble isn't affecting the earths magnetic field something is causing it to change and that could be screwing up the animals.

We know that many birds migrations are guided by Earth's magnetic fields, and that their changing will cause problems for the birds. I've posted a few stories on it; like the North American Red Winged Blackbird being seen in the UK.
But where has anyone shown it relates to bears?
