It remains to be seen whether this prognosis turns out to be true (there have been some doubts expressed), but since
grand minima of solar activity did
occur in the past, it is certainly interesting to explore what effects such a
minimum might have on 21st century climate if it did
occur.
Did you know that people are arguing when (and not if) the
grand solar
minimum occurs, whether it will be a Dalton or Maunder type
minimum?
Grand minima disrupt this wave and also can only

If we look over the LIA (1250 - 1850) the gap between

occurred during this period.

The future is easy to predict, no
grand minima will
occur during the ordered phase (as seen across the whole Holocene) and we will see weak
grand minima separated by roughly 200 years for about 2000 years... I think we agree on this but my reasoning has a driver.
