Possible relationship to climate[edit]
There is evidence that geomagnetic excursions may be associated with episodes of rapid short-term climatic cooling during periods of continental glaciation (ice ages).[5]
Recent analysis of the geomagnetic reversal frequency, oxygen isotope record, and tectonic plate subduction rate, which are indicators of the changes in the heat flux at the core mantle boundary, climate and plate tectonic activity, shows that all these changes indicate similar rhythms on million years’ timescale in the Cenozoic Era occurring with the common fundamental periodicity of ∼13 Myr during most of the time.[6]

IF this is true then if we are in a geomagnetic excursion and not a Geomagnetic full reversal then we might be coming into an ice age.
This also makes sense because historically ice ages often follow global warming like we are presently experiencing.
Also, the north pole was once at 76 degrees Fahrenheit. It then took thousands of years of ferns from the north pole to the equator to eat up the carbon dioxide to return earth to what we experienced in the 20th century from 1900 to 2000 before we started breaking heat records now almost every year around the globe.
