Interesting when the whole Guassian science was invented in 1835. Ability to measure to that quantitave degree just a few years later is historically phenomenal. Or BS. And your Wiki post is telling don't you think?
Have not read all the posts regarding the shifting of the Poles, but I would just say that the Poles rotate around the axis of the true poles all the time. The Magnetic axis rotates through about 12.5 degrees over roughly a 25 year period. Its position relative to true north is recorded in the Nautical almanac, and has been known and predicted for the best part of 500 years, if my memory serves me correctly
The problem is that we seem to very long overdue for the next reversal. So while we could infact be thousands of years away from the next one, it could on the other hand also be within the next year or two.
They've also learned what happens during a magnetic flip. Reversals take a few thousand years to complete, and during that time--contrary to popular belief--the magnetic field does not vanish. "It just gets more complicated," says Glatzmaier. Magnetic lines of force near Earth's surface become twisted and tangled, and magnetic poles pop up in unaccustomed places. A south magnetic pole might emerge over Africa, for instance, or a north pole over Tahiti. Weird. But it's still a planetary magnetic field, and it still protects us from space radiation and solar storms.
....Or an explosive natural gas emission from under sea? ....
I actually experienced that one time!!!!! But it was in my living room, not undersea.
What about a solar "kill shot"? Or a destructive meteorite? Or an explosive natural gas emission from under sea? Or mega-quake? Or the Polar ice shelves calving and creating a super-tsunamai? Or a super-volcano arising in the Aleutian Islands? Or a killer virus originating out the African jungle resulting in billions of people bleeding out with liquid organs? Or a Ukranian super-flu that is hidden underneath the H1N1 virus? Or an orbital collision from the outer reaches of the solar system? Or my underwear being too small for my fat azz? All are possible. The latter likely.
