Magnetic North is shifting to Siberia from Canada...do you think?

Question

with global warming added that the equator could become the next North/South Pole?

FYI: Magnetic North has already being proven to be in the process of shifting from Canada to Siberia. (See link below).

Answer 1

NO!

Magnetic poles move because techtonic plates are floating on molten rock... the geography shifts and rolls around on a bed of molten iron... and that's that. It is not impacted by global warming, because it is below the Earth's crust at temperatures of thousands of degrees.

Magnetic poles have been shifting since they've been discovered. They've even flipped polarity. THIS HAS NOTHING TO DO WITH GLOBAL WARMING. Please note the following quote from the article you site:

"This may be part of a normal oscillation and it will eventually migrate back toward Canada,'' Joseph Stoner, a paleomagnetist at Oregon State University, said Thursday at an American Geophysical Union meeting.

Did you see... this is NORMAL oscillation.

Answer 2

The way the Earth's magnetic field works is complicated and not all that well understood. We do know, as you say, that the magnetic north pole is shifting.

This is normal and each day the pole goes on an 80 kilometre trip before returning to more or less the same place - in other words, it's always on the move. Whilst it goes backwards and forwards it's also drifting very slowly, it never quite returns to the same spot.

It's moving in the direction of Siberia, whether it gets there or not is something we can't say for certain. It may move off in a different direction.

The equator won't become a polar region as there are limits as to how far the north and south pole move - they're always fairly close to geographic and true north.

What my happen is that the two poles switch places, we know this has happened many times in the past, roughly at quarter of a million year intervals. Some people speculate that a change could happen very soon given that it's long overdue (790,000 years since the last switch). Others point out that polar switching isn't cyclical but random so could happen anytime - maybe soon, maybe a long, long time ahead.

It's probable that there is little interaction between magnetic polarity and global warming and if there is it *could* be occasioned by massive polar ice melting. This *could* knock the Earth off balance slightly which *could* have an effect on the hydromagnetic dynamo - the beleived interaction between the solid iron core at the centre of the Earth and the liquid iron that surrounds it.

The Earth's magnetic field does have a small role to play in global warming but it's not related to where the north and south poles are.

Answer 3

The magnetic pole is usually somewhere near the geographic pole, but not always. The Earth's magnetic field reverses over a period of tens of thosand of years or so, and right now we are entering a period (several thousand years long) of low field strength, where the dipole moment (and hence the idea of a pole) will be weak compared to the other multipoles. This has some effect on weather, since the interaction between the upper atmosphere and the solar wind depends on the Earth's magnetic field strength. After a couple thousand years of relatively weak magnetic field, the "north" magnetic pole will re-emerge in Antarctica, and the "south" magnetic poe will re-appear somewhere in the Arctic.

Answer 4

The magnetic north has always wandered but typically stayed relatively close to the earths axis of rotation. It is possible to move as far as the equator but highly unlikely. Also the time lines for global warming and the wandering of the magnetic north are vastly different. So to match global warming with the magnetic north at the equator is all but impossible.

Answer 5

As a geologist, I studied pole reversals slightly. they might learn previous reversals via finding on the remnant maganetism interior the basalts at mid ocean ridges. by using fact the magma cools, the magnetic crystals align with the Earth's container leaving a small remnant container. besides via analyzing those basalts, they have found out that the Earth's container adjustments on standard each few hundred thousand years. we are due. It starts to weaken and spiral faraway from the axis of rotation. it appears that evidently to be weaking and spiralling terrific now. by using fact the magetic container blocks cosmic rays and cosmic rays are theoretically probably impact cloud formation, a weakening container ought to have some thing to do with climate substitute. i do no longer think of the moving magnetic axis has any significant result, basically probably the weakening container. the situation is that a weakening container ought to reason extra rays, extra clouds, for that reason cooling. this is a technique that takes hundreds of years. there will be a time as quickly as we've little or no magnetic container if it behaves interior an identical way. It should not be in our lifetime, i do no longer think of it may be catastrophic, inspite of the shown fact that it ought to no longer be very solid the two. it ought to to illustrate considerably improve maximum cancers expenditures. i do no longer comprehend if this is genuine yet i think it.

Answer 6

I think shifts in the earths polarisation is the least of our worries all that will happen is our electricity and electronics and radios and have to be redesigned wont work (which could be a good thing or bad) and animals will get confused on direction.

It happens about once every 40,000 years and it is a phenomenon of science to what happens when it does it and why it does it

The carbon could very well be slowing the earths rotation which is apparantly throwing it out of orbit which could mean the poles are shifting.

Answer 7

I think Patti C may have hit on something here in regards to Global Warming...


"Did you see... this is NORMAL oscillation."

So is the global climate.

Have any of you armchair scientists dug into this at all? Are the oscillations concurrent with temperature changes?

Answer 8

California is also heading to Alaska. So why would any body care? It affects nothing. Its going to happen so slow that when it gets there it will be a point of curiosity to people that it once was some where else.

Answer 9

it is unlikely that equator will become the north pole

even if it going to happen in the future, we will not be the ones to witness that

for a change as big as that , it will take forever, we won't be alive when that happens
