not sure what you're referencing, this is off topic so I choose to decline comment here.So, jc, you were thinking there was some sort of correlation between clouds and warming? That's been explored pretty thoroughly and hasn't brought up much. There were those folks at CERN who decided they'd found other ways to make clouds and it might be of help to the modelers, but it doesn't refute AGW. It doesn't even put a wee dent in it.
So, what were you thinking?
I assumed you were attempting to show that the science wasn't settled and thus WERE on-topic.
So what was the purpose of your query about older records of cloud cover?
