Poles reversing?

[erick (Eric)]

I read somewhere that the atmosphere will have to cope with the solar wind and cosmic radiation for a while. I guess we'll lose some atmosphere. But, look on the bright side - weaker aurora will be seen from all over the world!

That has got to be one of the most profound examples of lateral thinking I have ever come across.

Hi Steve! You precipitated a trip down memory lane as I dusted off a lot of my old geology text books! These were written at a time when continental drift was a relatively new theory (in wide acceptance anyway), and as far as I can gather, the suggestion that magnetic anomolies along oceanic ridges could be related to the spreading mechanism was first made by F J Vine and D H Matthews in an article titled "Magnetic Anomolies Over Oceanic Ridges", in "Nature", vol 199, p947, 1963.

Stand to be corrected on that, haven't gone the Wikipedia route!

Thanks Rob.

I did a year of geology at Uni in the late 70s.
Plate tectonics was still in its infancy but I recall being very impressed by the brilliance of that idea.

You're right there, Rob. Took me down memory lane too....1st year geology class Stuff you forget about as you specialise

We humans done pole reversal already. What we call North Pole is actually South Pole. Why – well the north end of magnetic needle in the compass points to it.

Curious that the magnetic field is dimishing allowing more radiation to enter the atmosphere, wonder if it is at the same rate as global warming is increasing.
