i should just mention that there is a lot of instability in the earth's magnetic field, for a decade or so now it has been moving around a lot more than since records were kept, and that recent research has determined there is a cyclical polarity shift that propagates out from the centre of our galaxy that passes across us every 12500 years or so

recently there has been strong signs of a greatly weakening field and a comensurate increase in stellar radiation getting to ground than normal as well, and increasing auroral activity

even more emphatically than you are, all of that says that nothing that humans are doing matters one iota if the galactic field is gonna flip, we are just gonna have to roll with that, and learn how to live for several decades without electricity, while many of us get washed away or die of cancer (possibly the lack of poisoned food might reverse that trend even with increased radiation)

they are just creating a cover story for phenomena that credible astrophysicists are already sounding alarm bells about and they want to make sure they get their doomsday bunkers in all the right places before the grids all fuse and the cities full of democrat voters suffer from more than a week of starvation and start eating each other
