They are impact events, supernovae, volcanism and geomagnetic reversals that occur simultaneously with high solar activity. The past record of geomagnetic reversals was first noticed by observing the magnetic stripe anomalies on the ocean floor.

It is fairly certain, though, that in the last 50,000 years there have been no geomagnetic reversals or global polarity excursions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There are two kinds of geophysical event which can affect production: geomagnetic reversals and polarity excursions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The record of geomagnetic reversals preserved in volcanic and sedimentary rock sequences (magnetostratigraphy) provides a time-scale that is used as a geochronologic tool.

In the 1960s, the past record of geomagnetic reversals was noticed by observing the magnetic stripe anomalies on the ocean floor. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Most scientific estimates, however, say that geomagnetic reversals take between 1,000 and 10,000 years to complete, and do not start on any particular date. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The magnetic susceptibility profiles of these sediments have been dated using magnetostratigraphy, which identifies geomagnetic reversals, and correlated with climate indicators such as oxygen isotope stages.
