WebThere is no evidence of a correlation between mass extinctions and magnetic pole reversals.Earth’s magnetic field and its atmosphere protect us from solar radiation. It’s not clear whether a weak magnetic field during a polarity transition would allow enough solar radiation to reach the Earth's surface that it would cause extinctions.

Unlike the Earth however, the Sun’s global dipole magnetic field flips or reverses polarity every 11 years around the maximum phase of each 11 year solar cycle. During the reversal, the polarity of the solar polar fields in both hemispheres reverses or changes to the opposite polarity. epps kennels california
