the magnetic field blocks the space weather, it deflects the flows of electrons and plasma and high energy particles

what doesn't get deflected, tends to end up following the flux lines of the magnetic field down into the poles, where it doesn't affect us so much because it's all icy cold deserts

when the field gets weaker, and when it gets weaker, it tends to move around a lot more also, because there is many globs of ferromagnetic stuff in the planet, on the crust, and blobbing around in the semi-liquid hot lava and dense core of the planet, none of it is entirely static and the crust especially is not consistent, there is regions of high magnetic permeability and low, and those layers move around a bit, very slowly, as well, and the lava parts are especially mobile

so if the coherence of the magnetic field becomes weaker, which would probably be because the direction of magnetic fields around the solar system are changing direction, causing the flux lines to cross and neutralize, you get a weaker magnetic shield, and this means more energy gets to the earth from the sun, and more of ti travels down to lower latitudes than normal

there is also further escalations to this that continue, in addition to the main magnetic pole of the earth, there is semi-permanent, very stable dense flux arcs that make these "magnetic zones" especially between the outer edges of the temperate zones, when the main pole becomes weak, these secondary flux paths become conduits for energy, giving rise to a phenomenon known as the Cosmic Thunderbolt, which is basically a lightning strike that is the size of ... well... like half the USA landmass can suddenly become electrified and i'm sure you can imagine that makes all the nuclear weapons in the world right now look like cap guns

this is all stuff to look forward to, whether or not and how much of it actually happens is another thing, it's like weather, except from space

one of the things that this leads me to was looking to see if someone made a lightning strike map, and sure enough, there is, and it's my firm opinion that everywhere there is very rare lightning strikes, at high altitude, is the right place to plan to set up for the next 50 years or so

notably that includes the eastern rockies, mongolia, a little bit of western balkans, some patches here and there in north africa, central australia, sorry to say it but south america's too low and flat, almost none of that part of the americas is going to be safe
