I've done a little searching on the possibility of earths magnetic poles shifting, and the consensus seems to be that they will move faster and faster over time and then have one major shift. Some people call this "flipping", but there is some argument as to where the poles will actually wind up.
If the earth was a clock face, some say the magnetic north pole will move to around 5:00 and the south pole to around 10:00. Is this what others have seen or are you getting other information? It certainly makes a difference how far inland you need to go and future climate for growing food.

Reports that I have seen now seem to predict a timeline that is much longer, hundreds of thousands of years. Crops & oceans would be minimally affected. The greater question will be how the solar wind and the magnetic shield intercepting cosmic days will react.
do some research on this... the earths magnetic shield in it's current position is why we are able to live and why the climate has remained relatively steady over the last many thousand years. If it flips (or changes substantially) - and it will at some point - how and where it flips to will make a BIG difference.

No argument I'm aware.
I took a geology course with Professor Emeritus Madeline Briskine. She's the one who discovered it. Her team was drilling core samples on the Mid-Atlantic Ridge. When examining the core samples, they noticed the alignment of iron crystals varied at regular intervals.
Magnetic reversals occur on average about every 435,000 years. That's just the average. The last was 730,000 years or so ago.
They're perfectly normal, and there are no known extinction events associated with them, meaning they have no effect on Earth's abundant life-forms.
Of course, those magnetic reversals took place in a world without technology, well, okay, I guess stone tools are "technology" if you want to get right down to it.
Anyway, North is North and South is South, except when North is South and South is North.
My understanding is a magnetic reversal would not affect direct current, but it would affect alternating current.
Maybe it will happen in our life-time and we'll get to see what happens first-hand, or maybe not.
