well as I said I’m no scientist
but your post does not answer that question “do cosmic rays help create clouds” (and if so does it account for a certain % of observed temperature changes in the lower atmosphere etc.)
it’s one thing to say similar lab set-ups have been used for 50+ years, but has this specific question been answered or not?
I don’t know why some at CERN and elsewhere think this is an important experiment worthy of a lot of money and scientist-hours, but they seem to believe that this question has yet to be answered.....
The answers are "yes" and "yes". If you know the physics of how cloud chambers work (which we do), then we know that cosmic rays unquestionably DO help create clouds. The ONLY thing this experiment "might" do is generate more precise data to answer the quantitative question of "how much". But the problem is that any data generated in lab experiments get plugged into math models, which have the same problems as CO2/warming models....they are MODELS. And unless verified by field experiments (which I have no idea how anyone would do) basically PROVE nothing.
