Are Volcanos Linked to the Solar Cycles.

In Arxiv:2203.03637, Valentina Zharkov Shows links between the 22-year Solar Cycle, and Volcanic Activity. During Solar Cycle 26, from 2031-2041, Volcanos would be a maximam, cooling the Earth, with possible effects on Food Production, if she is correct. This would mean that any Net Zero Plan, aiming targets at 2030, would leave the planet cold and hungry. Over the longer term, her mechanism would average out. I wonder if the effect of the Earths Iron Core, passing through the Suns magnetic field that reverses each 11 years. Could be the mechanism of her effect. The Earth has its own electric current in its magnetic dynamo, and when the Earths Natural Current is aligned with the current Induced by the Sun, an increased current will heat the Earths Core. If I have time, I will look into quantifying the numbers for this mechanism. Zharkov is a Plasma Physicist, so should also be more than capable of quantifying the numbers.
