Lower sunspots means less chance of solar disruption to the power grid. Although I would think that even in a period of low sunspots there is still the rare chance of a disruptive solar flare.
And low sunspots is associated with less energy coming from the sun, energy that warms the earth. So temperatures will probably go down. I imagine there are other factors (one NOT being mankind’s emissions of “global warming gases”).
The last long-term period of low sunspot numbers had low temperatures, “the year without summer”, poor crop yields, etc. Of course that might stress the grid with everyone plugging in their electric heaters. Seriously.
If one looks at the VERY long term (not hundreds, but thousands of years), I predict that we may very well be approaching an honest to goodness, mile-thick ice over Seattle Ice Age.
Thanks.
