«The sun causes latitudinal climate zone shifting with changes in the degree of jetstream zonality / meridionality by altering the ozone creation / destruction balance differentially at different heights above the tropopause.

My own view is that the initiating mechanism is not small shifts in insolation hitting some kind of trigger related to snow albedo (the land - sea snow - ice area is relatively small compared to potential shifts in cloud amount and spatial distribution)-- rather it is shifts in global winds which likely relate to shifts in the jetstream (linked to...?

The poleward shift of the Southern Hemisphere middle latitude jetstream in response to increasing carbon dioxide is one of the most robust circulation responses found in climate change experiments, and is predicted to occur during all seasons (IPCC, 2007c).
