I read something several years ago that described how our sun moves in a
kind of circular path through space near the outer edge of the Milky Way
galaxy. There apparently are large clouds of interstellar dust arranged
in a kind of pinwheel fashion within the galaxy with arms extending out
radially from the center of the galaxy ... thicker arms near the center
of the galaxy, thinner arms tapering to points at the edges of the
galaxy. Our sun passes in and out of those arms of the dust pinwheel,
and the article said that scientists have found a reasonable correlation
between the time periods between those passages and the time periods
between past ice ages. It would seem reasonable that the sun's nuclear
engine might be affected by all that "pollution" being dumped into the
reaction. If there is indeed such an effect I would think it would
affect sunspots as well, and that article claimed that we were in the
process of entering one of those arms again.
I'll see if I can dig up the reference again. At the very least it
seems to represent a plausible suggestion that solar predictions may
need to look at external influences as well.
