I'm not aware of any change in story.
No calculations exist until someone addresses quantitatively the matters of:
1) Measuring the average net position of the jetstreams on a day to day basis.
2) Measuring the global net effect of all the oceanic oscillations combined on a periodic basis.
I'd happily have a go if I get a suitable budget but that is certainly the direction the research needs to go.
The sun heats the oceans, the oceans heat (or rather maintain the temperature of) the atmosphere.Lean and Rind now seem to think solar variation is rapid and measurable in so far as it affects climate. Quite a shift from previous expert opinion.
I know that my ideas are not mainstream but they work so far. There would be nothing for me to say if I just parrotted the mainstream consensus (which appears to have no predictive capability).
I've edited my previous post to cover the ocean height issue.
