In fact I made in 1898 a 102-page treatise about Sun and its spots.

I'm very sure that Sun is a variable star, not in the traditional sense,
but in a minor scale.

And therefore also the Sun's activity is surely one agent that regulates
the ice ages, Milankowicz cycles are only a part of the eplanation, and
interstellar clouds a third (see the other letter).
