These "cosmic rays" (CRs) cause ionization of molecules in the atmosphere, and thereby can cause clouds to form (because the ionized molecules or dust particle can act as "seeds" for drop formation).

Note this phenomenon has actually been replicated in a laboratory; it doesn't rely on unvalidated computer models.

Last I'm aware, most "climate change" computer models don't even take into account varying cloud cover. And, yes, the experimental apparatus is called a "cloud chamber".

The basic idea is that when an increased number of galactic cosmic rays (electrically charged particles from outside the solar system) reach the atmosphere a greater number of sun-blocking clouds are formed, thus leading to cooler times. But during periods of increased solar activity, more cosmic rays are deflected away from Earth than usual, less Sun-blocking clouds form, and the Earth warms (naturally).

100,000-Year Climate Pattern Linked To Sun's Magnetic Cycles:

ScienceDaily (Jun. 7, 2002) HANOVER, N.H.
Thanks to new calculations by a Dartmouth geochemist, scientists are now looking at the earth's climate history in a new light. Mukul Sharma, Assistant Professor of Earth Sciences at Dartmouth, examined existing sets of geophysical data and noticed something remarkable: the sun's magnetic activity is varying in 100,000-year cycles, a much longer time span than previously thought, and this solar activity, in turn, may likely cause the 100,000-year climate cycles on earth. This research helps scientists understand past climate trends and prepare for future ones.

The Center for Sun-Climate Research at the DNSC (Danish National Space Center) investigates the connection between variations in the intensity of cosmic rays and climatic changes on Earth. This field of research has been given the name 'cosmoclimatology'"..."Cosmic ray intensities – and therefore cloudiness – keep changing because the Sun's magnetic field varies in its ability to repel cosmic rays coming from the Galaxy, before they can reach the Earth." :

Note: their section on this topic has changed in recent years.

Yes, that is how cosmic rays were first confirmed-- tracks of condensation in a "cloud chamber."
