I have been going on about "the lag", be it 10, 30-40, 100 or 200 years, for as long as I can remember. Very few people understand that what we do today does not manifest itself tomorrow.... it bites back way into the future. Ah well....
When and how it bites back, and its effects, are also dependent on all those cycles I keep talking about, be they astronomical or global.
My children will, hopefully, be OK. The fate of any grandchildren is very uncertain and I would not want to be one of their generation.
