When solar cycles are shorter than 11 years over several cycles the planet warms; when cycles are longer than 11 year for a few cycles, the planet cools. There has been a strong (95%) correlation between the solar cycle and cooling and warming of the northern hemisphere over the past 150 years.

Here is how it works. When sunspot peaks are far apart, the electromagnetic shield is down for a long period of time, cosmic radiation seeds the clouds, and there is more rain and snow (with its albedo reflectivity) and the planet cools (Svensmark, J. et al., 2016). The rainfall makes sense in this context because cooling results in condensation. When the sunspot peaks are frequent the minima have less effect and earth warms (Svensmark, H. and Friis-Christensen, 1997; Svensmark H., et al. 2007).

This pattern is completely consistent with the extremes, the thundery hot summers and cold winters of the Little Ice Age which coincided with the Maunder Minimum when sunspots were few or completely absent for 60 years. Zharkova’s research group is predicting another Little Ice Age beginning right now, today, or at the end of Cycle 24. So think many others who study the sun and think it trumps carbon dioxide (Shaviv, 1998).

How does that happen? Here’s how. NASA says, as we enter the solar minimum, our wispy atmosphere shrinks. NASA has learned to juggle satellites that drop into lower orbits during the solar cycle. Lower down in our atmosphere the sun drives our winds and the most important winds of all, that rule all the others, are the jet streams that power around the planet at well over 160 kilometres an hour.
When the atmosphere contracts, the jets start to meander. The meandering happens because there is a space problem; the same jet stream is jammed into less volume within a shrunken atmosphere; hence the jet streams kink. The cloud levels are slightly but measurably lower as well.
