The Guardian 31 Dec 2020: Caribbean volcanoes rumble to life as scientists study activity not seen in years

It's counterintuitive that the relationship between solar activity and volcanic activity is inverse; solar minima, with less kinetic energy, are accompanied by more, not less, volcanic eruptions. "Volcanic Eruptions and Solar Activity," Richard B. Stothers, Solid Earth Journal of Geophysical Research 10 December 1989:
[Volcanic] cycles appear to correlate with well‐known cycles of solar activity; the phasing is such that the frequency of volcanic eruptions increases (decreases) slightly around the times of solar minimum (maximum). . . Mechanisms to explain the Sun‐volcano link probably involve induced changes in the basic state of the atmosphere. Solar flares are believed to cause changes in atmospheric circulation patterns that abruptly alter the Earth's spin. The resulting jolt probably triggers small earthquakes which may temporarily relieve some of the stress in volcanic magma chambers, thereby weakening, postponing, or even aborting imminent large eruptions. In addition, decreased atmospheric precipitation around the years of solar maximum may cause a relative deficit of phreatomagmatic eruptions at those times.
"Possible correlation between solar and volcanic activity in a long-term scale" Střeštik, J., International Solar Cycle Studies (ISCS) Symposium, 23 - 28 June 2003:
Volcanic activity is usually higher in periods of prolonged minima of solar activity and vice versa. However, the mechanism of this forcing is not known. Perhaps geomagnetic activity mediates solar influences (unfortunately, series of these data are too short).

Without exhaustively searching, it doesn't look like anyone has suggested a model whereby less solar activity causes the earth's crust to cool and contract, resulting in pressure release. This seems at least as plausible as anything proposed so far, but perhaps the reason it hasn't been floated is that it conflicts with the climate change narrative. After all, if cooling results in volcanic activity, it probably presents a greater existential threat than warming.

I'm wondering, is this the reason for the frantic pace of the agenda rollouts? They seem to be working against a deadline, and they keep saying we have a narrow window of opportunity to remake the world. What's the rush?
