It's not the cosmic rays that'll kill 'ya ...

“Maybe we’d get back to reading books.”
No way, I haven’t opened a book since i graduated from college 55 years ago!
I would miss my kindle. Its just a basic no frills number but I use it a lot and it beats carrying a book to the bathroom every time I go.
I smoke, I drink, I play with dangerous equipment, and I have 3 ex wives.
I decline to worry about cosmic rays. ;)

Run for the hills, if you can find them. We are all doomed!
It would be terrible. We would have to print new maps with new declination information. We might go a day without Kanye tweets while communication systems are recalibrated.
OR it is another excuse to increase government power in the name of protecting us.
Actually Liberals are parasites & moochers & over all less self reliant, so a world wide disaster or collapse, Liberals will die first.
Not the Stone Age. The laws of physics will remain unaltered and steam will still work just fine, and that’s just for starters. FReeping will be a little slower, to be sure.
Where is the great spot located...over the Bermuda triangle?
An increase of beryllium-10 was noted in a 2012 German study showing a peak of beryllium-10 in Greenland ice cores during a brief complete reversal 41,000 years ago which led to the magnetic field strength dropping to an estimated 5% of normal during the reversal. There is evidence that this occurs both during secular variation and during reversals.
Another hypothesis by McCormac and Evans assumes that the Earth's field would disappear entirely during reversals. They argue that the atmosphere of Mars may have been eroded away by the solar wind because it had no magnetic field to protect it. They predict that ions would be stripped away from Earth's atmosphere above 100 km. However, the evidence from paleointensity measurements is that the magnetic field does not disappear. Based on paleointensity data for the last 800,000 years, the magnetopause is still estimated to be at about 3 Earth radii during the Brunhes-Matuyama reversal. Even if the magnetic field disappeared, the solar wind may induce a sufficient magnetic field in the Earth's ionosphere to shield the surface from energetic particles.
Hypotheses have also been advanced linking reversals to mass extinctions. Many such arguments were based on an apparent periodicity in the rate of reversals; more careful analyses show that the reversal record is not periodic. It may be, however, that the ends of superchrons have caused vigorous convection leading to widespread volcanism, and that the subsequent airborne ash caused extinctions.
Tests of correlations between extinctions and reversals are difficult for a number of reasons. Larger animals are too scarce in the fossil record for good statistics, so paleontologists have analyzed microfossil extinctions. Even microfossil data can be unreliable if there are hiatuses in the fossil record. It can appear that the extinction occurs at the end of a polarity interval when the rest of that polarity interval was simply eroded away. Statistical analysis shows no evidence for a correlation between reversals and extinctions.
Iron Age maybe.
I’m a hobby blacksmith so that idea does have a bit of appeal to me...
Another question: it is hypothesized in the article that these shifts might cause increased volvanic activity. Might they also cause mega-storms such as we've seen over the past decade or so? Because if they can, the shifts could lead to megastorms could lead to extinctions, you'd think.

Figure this thread is a good enough place to say this:
If you watch Ancient Aliens, they would have you believe that every un-explained phenomenon must have occurred with alien help. But I have another theory that may also explain the so called ‘cave man’: As a rule, every generation think they are smarter than the last. But with all the high-tech relics found on earth over the years, structures built to mathematical perfection for no apparent reason, I am a believer that something happened in human history (when they were much more advanced than we think) so cataclysmic that a good deal of our history is simply... missing.
It would make sense if you think that those who may have survived that cataclysmic event were so busy surviving, there wasn’t time to write down the details of what happened. but it could have been something like a polar magnetic shift. Could have caused the Great Flood perhaps?
Just my $.02

I’ll bet there are scientists and government sponges lined up around the globe ready to pounce on that very thing!
