E a proposito di Piccola Era Glaciale e di vulcanismo (per quelli che: “la relazione tra attività solare e attività vulcanica è incerta…”)
Our predictions indicate that the present Cycle 24 is expected to be a low-peak cycle. We conclude that the level of solar activity is likely to be reduced significantly during the next 90 years, somewhat resembling the Maunder Minimum period.
On the Verge of a Grand Solar Minimum: A Second Maunder Minimum?Solar Physics, First online: 30 April 2015
The frequency of volcanic eruptions increases (decreases) slightly around the times of solar minimum (maximum).
Stothers, R.B., 1989,Volcanic eruptions and solar activity. J. Geophys. Res., 94
We examined the timing of 11 eruptive events that produced silica-rich magma from four volcanoes in Japan (Mt. Fuji, Mt. Usu, Myojin-sho, and Satsuma-Iwo-jima) over the past 306 years (from AD 1700 to AD 2005). Nine of the 11 events occurred during inactive phases of solar magnetic activity (solar minimum), which is well indexed by the group sunspot number. This strong…
