This is a lengthy video but for those that would be interested; the video explains the process discovered way before political global warming came around, it also shows that back in the 60s and way before that, science understood that there was a connection between sun and earth/climate and they were correct to point out at that time that we would eventually head into and extended cold period another mini ice age.

This discussion also shows us that Ben Davidson has it together on this and many other subjects.
