1) I'm using 'life' within the context of space weather 'catastrophes', or 'extinction events' on Earth.
2) 'Carrington Event-like-events' are not associated with any loss of life, just burnt-out electronics.
3) Whole-building spike-protectors might isolate homes, businesses, and medical facilities from utility-interfaced circuit damage.
4) Spare transformers ( if for-profit utility bean-counters will allow the cost ) and already-trained linepersons would immediately replace the fried equipment once the storm passed.
5) Aircraft inertial navigation gyros are impervious to any atmospheric disturbance.
6) Major Solar Flares are no predictor of solar storms, as no one can predict how an impinging field would be oriented.

7) As to Geomagnetic Reversals:
* There have been 800 Reversals over the past 160-million years, with no extinction events, nor any proxy evidence for extreme cosmic ray bombardment ( rock weathering ).
* There have been 14-Excursions over the past 780-000 years, with no extinctions or extreme cosmic ray bombardment ( rock weathering ).
* Polarities average 200,000 years.
