Is it possible that the LOD correlation to multidecadal global temperature variations is just an example of a forcing response to an ocean basin’s sloshing behavior?
Changes in LOD are angular momentum changes and those get directly translated to forcing inputs to the precarious thermocline stability. The ~4 year lag between forcing and response may be explained by the thermal mass in the system.
Once the SOI Model is integrated into CSALT, the only unknowns left to natural variability are LOD and volcanic impact. Since multi-year LOD is slowly varying, that may be relatively easy to forecast a few years in advance, which only leaves volcanoes as an unknown.

I know that you are busy man but you may want to consider the following publications about lunar tides, LOD and their link to ENSO/PDO. The first link in particular questions your assumption that C02 was responsible for most of the warming in the latter 20th century:

A SIMPLE MODEL FOR THE 18.6 YEAR ATMOSPHERIC TIDAL OSCILLATION

Hypothesis: The -12.57 μsec change in the length-of-day
(LOD) associated with the 18.6 year Draconic lunar tides,
is a direct result of a systematic one degree shift to the
South/North by the Southern/Northern Summer Sub-Tropical
High Pressure Ridge that is produced by lunar atmospheric
tides.

Paul, I am not attempting to convert you over to the “dark-side”. Even skeptics like me are truly impressed the quality of research that you are doing. What I am doing is try to show you the some of the work that I have done in order to stimulate your thought processes in the (humble) hope that it may help to expand the boundaries of scientific discovery.

Ian, I queued a comment on your latest blog post.

Perhaps it’s informative to explain the multipliers of 9 and 2 to get at the 2.33 number.

It looks like the comment of September 30, 2015 at 9:54 am got stuck in automatic moderation for a few days, probably because of its length.

Actually, it says nothing about the 20th century’s global warming trend. The use of *detrended* global temperature anomalies pretty much makes it impossible to explain a trend that has been removed.
Vis a vis global temperatures, all it shows is that anomalies go up duriing El Ninos and down during La Ninas. I don’t think that has ever been questioned.

Kevin,
Yes, its funny how selective some people can be when it comes to analysis of time-series. I know the reason that Ian is looking at this topic is to hopefully find an alternate explanation for global warming.
In contrast, I am just looking at it as interesting science.
Yet Ian isn’t anywhere close to the worst of the lot when it comes to desperation tactics. He is pretty mild compared to many I have come across.
