It is the interplay and overlap of the 11 cycles that drive the changes shown in the charts. Stand back and look at them and you will see more and more repetition over time. The shortest cycle is 11 years, the longest 3 million. To the untrained eye the patterns may look random but they’re not. I haven’t worked in this field in over thirty years so I’m a little rusty.
I greatly appreciate your time to share this. Yes I have been playing with paleo-climatology as a hobby since the early 80’s. And still trying to figure out what actually causes some of these cycles. But there is no doubting the cycles, they are real and to be heeded in the longer term.
We are definitely headed into another glacial period, it is late. Just as we always have and always will. Average solar insolation started to decline about 8,000 and we are still catching up to that change. None of this happens fast or in one lifetime. It all needs to be looked at from a much longer timeframe to see the reality of it.
