Thanks for forwarding this. The article comparing climatic changes with stock market changes was fascinating. (Sorry, couldn't make the link work to post it on the thread). It discusses the mathematical similarities in the difficulties of proper analysis of both fields....it's tough to determine what is normal fluctuation and what is a real change in parameters.
I'm wondering if maybe the cycles in global change might be intensified and the the cycles might have greater frequenty (shorter period or interval) because of environmental issues.
I saw an article last year that had strong evidence that the hole in the ozone layer is actually caused by sunspot activity, and not CFCs as some had previously hypothesized.
IMO, the sunspot causation makes much more sense....
