That's an incredibly short sighted view...
When things like mag field flips happen on a scale of thousands or tens of thousands of years, then I don’t see a reason to take the alarmists point of view. The prediction models as to the earths magnetic core just aren’t there. They have to be updated every 5 years (IGRS, WMM) to get present values and the future is strictly extrapolated. Not really predictive. Just best guess.
