This is on the sun, not the earth.
I think you are talking about the 2012 prediction some have made of us hitting a solar maximum at the same time as the earth swaps magnetic poles.
The thing to remember is that it takes 10k years for the poles to reverse but during that time the earth’s magnetic field does weaken.
pole swap on the sun? I will have to google it
I know the piece is about the sun. I thought you were talking about Earth’s magnetic field, sorry.
