“Lack of sunspots” is in indication of conditions leading to cooling.”
Lack of sunspots is an indication of a strong dipolar field that decreases sunspots. The stronger the dipolar field the colder it becomes. The same is true for earth.
The polarity reversal only happens in a weak dipolar field. It warms up during this period.

SOLAR WIND, INCOMING: A wide hole is opening in the sun’s atmosphere, and it is spewing a stream of solar wind toward Earth. G1-class geomagnetic storms are possible when the gaseous material arrives on April 19-20. Sky watchers between 50o and 60o N latitude should also be alert for STEVE, which tends to appear in that latitude range during springtime geomagnetic storms.
