Grand solar minima and maxima of sunspot numbers pose an increased risk for climate-forcing volcanism. This is evidenced by the fact that 56/73 large eruptions (&lt;-5W/m2) in the last 11,000 years occurred at or within one decade of a grand solar minimum or maximum (87% ±2 decades). Sunspot numbers used in this graphic were derived from terrestrial tree rings measuring radiocarbon C14 isotopes, indicating a solar magnetism-related mechanism is involved. This raises the question; "are grand solar extremes (i.e., magnetized solar wind) acting as a “climate oscillator” through volcanism (&lt;-5W/m2 radiative forcing impact)"?
