This post will be unusual because of no links, no pics. I’ve looked at many articles and they’re all speculative, from those assuring us it’s not going to happen, to it’s not going to hurt us, to dire consequences for humans.
From what I can gather, it’s happened many times before, it’s 100,000 years overdue but if it does come, it might be soon and might be much faster than the earlier ones. We know the pole is moving towards Greenland and accelerating but whether the flip happens is up in the air.
Consequences? Not a lot from the flip beyond loss of communications for some time but the greater danger appears to be a weakened field, which lets nasties in like solar winds and other space debris.
Again speculative but there were living thing wipeouts in the past. Were these due to flips? Who knows? One thing I read was oxygen loss, meaning oxygen depletion. Another was increasing tsunamis and the like.
If it does occur, it’s meant to be for 200 to 400 years, then back again. So we’ll be somewhere else by then.
