Hi Stephen, Thanks for this paper with an interesting theory about the 100,000 year cycles. Generally speaking the warming in periods of de-glaciation is more rapid than the cooling during glaciation, so you get a saw-tooth curve, both for the 100,000 year cycle and sub-cycles within it. I

The goal is not weather modification or anything to do with weather but to alter/control slightly the average, local, long term temperature i.e. local climate modification not weather control. Hence your comments on controlling weather offer no insight into a totally different issue. Limited

Hi Folks, Regrettably, I can not read the full paper and can only offer up minor comments/questions which might be covered in the full paper. The abstract closes with: ***Carbon dioxide is involved, but is not determinative, in the evolution of the 100,000-year glacial cycles.. *What is
