For 500 years global temps have followed a regular pattern: thirty years of warming, then thirty of cooling. We're now ten years into a new cooling spell...

Prior to the Little Ice Age, there was a prolonged warming period. (3 degree average, warmer than this recent one) The recent hyper Sun Spot activity over the last 10 years will be offset by the opposite. At least that is the way it is starting to look.

Gee a 2 thirty year cycles...

Could that possibly be related to the reason for the 60 day oriental calendar. Where there are 30 good years and 30 bad years...

And all of that related to the 12 year orbital of Jupiter and the 30 year orbital of Saturn that naturally lines up every 60 years?
