My fuzzy impression from [1] is even the high-order-100x density increase of solar/geomagnetic storms has limited impact on lifetime (above low-LEO where there's no need). Summer day vs winter night variability is already like 10x. I'm struggling to picture high-altitude explosions raising enough mass to do more.
