Maurice - I disagree with the oceanc current theory [flipping to a new flow process]. The ocean flows are driven not by temperature differences as hurricanes are, but by Coriolis forces resulting from earth's rotation.

Coriolis force cannot act on a still object, and in fact the slower the innate velocity, the less the force. Thus, thermal flows and salinity flows are the driving forces behind ocean currents. Both of these are strongly effected (affected?) by the global weather. But of course, no one is claiming that the currents will start flowing clockwise in the Northern Hemisphere. The concern is that some of the currents may start welling up in new locations, or may spawn smaller flows, or may merge or ... and that the new configuration may be relatively stable. As we know from El Nino, it doesn't take a large ocean temperature change to have a large impact on weather.

I'm pretty sure that insolation changes are the dominant effect and the expansion and shrinkage of forests [light absorbing greenery], ice cover and cloud cover.

Possible. I've never seen a good study of sun-type star variability in output.
