The New York Times On Earth's Magnetic Flip-Flop 519
TolkiEinstein writes "The New York Times reports that, relatively speaking, compasses may soon point South. It's long been known that Earth flips magnetically every half-million years or so, and, with the north pole's magnetic field at about 10-15 percent [less than] its strength of 150 years ago, many geologists feel a flip is coming up. Computer simulations also suggest that the current state of the magnetic field is indicative of an upcoming flip. Though it would take hundreds of years to complete, the impact on life may be significant but not catastrophic, including phenomena such as power-outages, satellite malfunctions and disruptions in the rhythmic functions of some animals such as loggerhead turtles. The EU plans to launch a trio of satellites in 2009 to assume polar orbits & monitor the field." (Cross your fingers for some nice solar wind.) Update: 07/13 17:02 GMT by T : Note: the summary here originally misstated the Times' article; the field 's strength has decreased 10-15 percent, rather than to 10-15 percent.

Modded funny, but you just watch - people WILL blame the government when it happens. No matter how much you try to explain, no matter how clear the explainations are, a significant number of people are going to blame the government.
It's also the case that whoever is in office is going to get burned by the problems - blamed for "lack of preparedness" or "failure to respond to the situation" etc, etc. And there will be calls for huge governmennt expenditures to "fix" or "solve" the problem.

Someone watched "The Core" one time too many. Earth's magnetic field does nothing to deflect UV radiation. I would recommend lead-lined clothing, not more sunblock. :)

No. In fact, frequently the opposite [urbandictionary.com] is what actually happens.

Even if some posts are in jest, we've had folks questioning the results of a simple magnetic shift affecting the direction of the coreolis affect, (toilet flushes), tilt of the earth (seasons), loss of the atmosphere, and viability of all satellites in orbit.
Even if it happened over a couple years (which it doesn't), the only affect I've seen which is certain to happen is that the Government will be blamed for it.

I don't understand why the Slashdot staff doesn't at least briefly research considered submissions to ensure they're are not dups and, more importantly, are accurate; spell checking submissions before posting them would be helpful too.

It does not point north! (Score:2, Insightful)
Hello, Earth to idiots...is it that hard to understand that a compass does NOT point north, but it aligns with magnetic north & SOUTH.
If you want your compass right now to point south, paint the other end, and when they flip if you still want it to point to our current north, paint it's corresponding end.
This aint rocket science for Christ sake. Anything that can distinguish "north & south" will work EXACTLY the same when the polls flip, as it will still be aligning with the magnetic polls, just like it always has and always will. Though your stupid little GPS programmed by stupid people who have stupidly programmed it to "point north" and not "align with the magnetic polls" as it does will probably not work right, but only because of the stupid programmers.
Do not ask me why, but this crap really pisses me off, go figure.
