Certainly, they will come back. Maybe not in our lifetimes!
The thing that scares me is this. If we are entering a minimum, the reaction of the sun might go like this for a while: Much lower (than average) lows, followed by the spots coming back with a vengeance. (I mean at the beginning of the minimum). Finally, for a few years, then settling down to lower lows and lower highs.
Make sense?
Have you seen “Knowing” with Nicholas Cage? Dang. I didn’t think it was possible to make a movie that was more depressing than “I am Legend” yet still be entertaining, but it did it. It’s, in part, about a sun spot coming back with a vengeance.
