Earth's magnetic field is generated by molten iron in its outer core. The flow of this liquid iron can influence the location of the planet's magnetic poles. While poles have drifted and even swapped places numerous times over the course of Earth's long history, what's different about this recent shift is how quickly it's happening. From 1999 to 2005, Earth's magnetic north pole went from shifting 9 miles at most each year to as much as 37 miles in a year.
The Magnetic North Pole Is Rapidly Moving Because of Some Blobs
These scientists pored over 20 years of satellite data from the European Space Administration's Swarm satellite mission and discovered that "...over the last two decades the position of the north magnetic pole has been largely determined by two large-scale lobes of negative magnetic flux on the core–mantle boundary under Canada and Siberia," according to the study.
Between 1970 and 1999, the flow of molten, magnetic material in Earth's outer core changed. Because of these changes, the researchers say, the magnetic blob lurking beneath Canada slowly elongated in the early aughts, weakening the corresponding magnetic intensity on Earth's surface.
A magnetic field is not crucial for having an atmosphere — Venus has no magnetic field and has a massive, if unwelcoming, atmosphere — but it certainly acts as an additional protective layer. Mars, which used to have a magnetic field but lost it some 4 billion years ago, has had its atmosphere almost entirely stripped away. And if there were a way to give the moon an Earth-like atmosphere, the solar wind would whittle it to nothing in a mere century, Archer said.

So what?

Interesting stuff.
Any info on if a magnetic shift could alter fault lines and or increase volcanic activities?

what is affecting the "blobs" seems to be affecting all of the planets at once.
Can you give some examples?
You mean like Jupiter's red spot?
Earth is heating up lately, but so are Mars, Pluto and other worlds in our solar system, leading some scientists to speculate that a change in the sun’s activity is the common thread linking all these baking events.
Other warming worlds
Others have pointed out anomalous warming on other worlds in our solar system.
Benny Peiser, a social anthropologist at Liverpool John Moores University who monitors studies and news reports of asteroids, global warming and other potentially apocalyptic topics, recently quoted in his daily electronic newsletter the following from a blog called Strata-Sphere:
“Global warming on Neptune's moon Triton as well as Jupiter and Pluto, and now Mars has some [scientists] scratching their heads over what could possibly be in common with the warming of all these planets … Could there be something in common with all the planets in our solar system that might cause them all to warm at the same time?”
Peiser included quotes from recent news articles that take up other aspects of the idea.
“I think it is an intriguing coincidence that warming trends have been observed on a number of very diverse planetary bodies in our solar system,” Peiser said in an email interview. “Perhaps this is just a fluke.”
In fact, scientists have alternative explanations for the anomalous warming on each of these other planetary bodies.
Interesting. More information, please.
I have seen that the jet stream may be influenced by the Earth's magnetic field.
Why?
And a slow process would be worst than a fast flip, for anything caught in the middle.
Please provide this evidence.
There is some evidence that when the magnetic field flips life on Earth is effected.
This new evidence is consistent with the factor-of-2 equator-to-pole paleointensity signature of a geocentric axial dipole field and also indicates that the time-averaged field is considerably weaker than the present-day field. The resulting dipole moment provides a new calibration standard for cosmogenic isotope production rates and suggests that the present decrease in geomagnetic field intensity may simply be a return to a more average magnitude rather than a harbinger of a polarity reversal.
Not kidding. Fascinating and makes sense.

Watch the first 2:40 of the video directly above your post. I warn ya ... you might get stuck there for the full hour that follows. -chuckle

There is clearly collusion between the Canadians and the Russians on this. There should be an investigation!

some jack has it on ebay for hundreds of dollars.
i wish i was rich, i would buy it, scan it, release to a-t-s for free.
