Something like a lot of sunspots result in high solar winds resulting in more capture of cosmic ray particles resulting in less seeding for clouds resulting in thinner and fewer clouds. Therefore more solar radiation is let in and the earth gets warmer.
We should expect cloudier weather, then, as sunspot activity fades. Which in turn would result in colder weather. And, much snowfall. I’m dreaming of a white Christmas....
There will be plenty of moisture up until we get to maximum ice age point. By then the moisture will be frozen and the oceans will have fallen 100s of feet and will be very cold. So the long term forecast is years of biblical rains switching to snow and glaciers. Followed by a few thousand years of cold drought. Mankind wont be able to change a thing except ride the roller coaster once again.
