Yes, be careful not too wade too deep into the solar stuff, and end up in climate risk denier territory.
Compare, compare, compare

'Tis the solstice.

Winter Solstice 2018 will be at 22:23 hrs Greenwich mean Time (GMT) on Friday, 21 December.

This is the solar cycle that interests me most, apart from the butterfly wings image of the sunspot cycles.

Imagine it is pre-history, and you do not know if this year the sun will start to rise higher in the sky again. Perhaps this time it will get lower and lower in the sky until......

We probably should pop an extra virgin in the volcano just to be sure. ???

Not interested in the dark side of this earth cycle at all, my 5360Wp PV's has produced 0.06kWh so far today and that's pretty much it, it's getting dark(er). A little snow on them for once...

Earth Cycle !?

We are in pre-history and you are telling the assembled throng it is not the sun rising and falling at various times of the year but movement of the earth around the sun and inclination of the earth's axis wot's doing it.

The Priest decides, to general acclamation, forget the virgin, it is you that's being thrown into the volcano. Insulting the Sun God is dangerous.

Come to think of it, there are plenty of evangelical churches today where a similar outcome would be likely.

Yet another study using development of the solar polar field strength claims a similar or slightly stronger cycle 25. Open access, just adding Fig 4.
