Had a quick read of this, understood very little of it, but of course caught the last few lines which read:

"The first of these oscillations may even turn out to be as strongly negative as around 1810, in which case a short Grand Minimum similar to the Dalton one might develop. This moderate-to-low-activity episode is expected to last for at least one Gleissberg cycle (60-100 years)."

This should give rise to further discussion / analysis by those with interest and knowledge of cycles and their possible or potential impact on weather?

A Dalton minimum-type possibility, eh?
