If the sunspot correlates with cooling through sun magnetosphere shrinking, and increased cloud nucleation from increased cosmic rays from the shrank protection from the solar magnetosphere, how come we won't get more rain? (wattsupwiththat.com)
A reduction of the solar wind during a prolonged solar minimum event would cause more galactic cosmic rays to enter the earth's atmosphere which would promote more aerosol formation thus more cloud nucleation. (informthepundits.wordpress.com)
However, cosmic rays may facilitate the generation of additional cloud nucleation particles thereby decreasing the average droplet size in clouds and hence increasing cloud albedo. (skepticalscience.com)
