Solar cycle 22 was quite high, 23 considerably lower, 24, the one we are in now, lower still, the low point of this cycle is predicted for 2019 or 20.
The scientists that are monitoring solar activity are still not sure about the mechanisms of the long cycle. When it was first proposed we did not have very good monitoring equipment. That has changed a lot, from ground based telescopes that are dedicated to that task to satellites, two such are Stereo A and Stereo B which are in orbit around the sun, one monitors the Earth facing side of the sun, the other the side facing away. The sun takes roughly 14 days to make one rotation. Some of the thought behind the two satellites is that if there is a potentially dangerous solar storm we will have some warning. A truly large solar flare directed at the Earth, can wipe out communications and the power grid.
Upcoming cycle 25 will give some indication if we are continuing into a deep minimum like the Maunder Minimum, that produced the little ice age from 1645 until 1715.
Another factor is the effects of solar heating on ocean currents, and how that affects the deep ocean currents.
Climate and what drives it is a pretty complex science, the prime driver is the sun.
Another poorly understood component of space weather is the increase in solar wind caused by coronal holes, these may also affect our climate, and are more prevalent during solar minimums.
