>It's possible that a magnetic reversal does not result in a geo-physical flipping of the planet.
it is highly probable that a magnetic pole reversal does NOT include a physical flipping of the planet.
there's been more than a few pole reversals in geologic history and no evidence of a physical flip.
the atmospheric anomalies you list that might result from a magnetic pole reversal are conservative.
the true extent of what a rapid pole reversal would do is hard to comprehend
