Interesting graph Robson. I dont remeber seeing one go this far back. While it took 100 years to get back to the trendline, it also to 25 years and the Great Depression to begin the overshoot. By then many of us would no longer be around.
I wonder how good the data is from 100+ years ago. Where the heck could they even find it? If it is good data, I’m impressed they could go that far back.
