If you've ever watched a cloud chamber with a mildly radioactive
element in it, you've seen the 'contrails' charged subatomic particles
leave. It's a classic way of demonstrating natural radioactivity and
atomic fission.

Cosmic rays are individual protons or heavy nuclei that can hit the
upper atmosphere with the energy of a pistol bullet. A collision with
an atmospheric molecule creates a shower of subatomic particles that
can reach the surface and can be detected photometrically.
Apparently, these particle showers also cause clouds as in the cloud
chamber - or at least condensation nuclei which later cause clouds. Or
perhaps in some cases, punch holes in them.

Don't pay too much attention to Soon or Svensmark - most of the climate
scientists don't, because their ideas about cosmic rays have very little
evidence to support them:
