Sorry for the delay, but NOMADS was off line for a few days early in the week and I got sidetracked with a few other posts.
I’ve elected to eliminate the Southern Oscillation Index (SOI) updates. At times, NINO3.4 SST anomalies don’t follow the SOI precisely, so the SOI can be misleading with respect to the overall direction of NINO3.4 SST. In its place, I’ve added the weekly Optimally Interpolated Sea Surface Temperature (OI.v2 SST) data for the NINO3.4 region.

Bob,
Superb effort, and very fascinating.
If you look at this:
http://www.freerepublic.com/focus/f-bloggers/1806245/posts
in particular at the atmospheric CO2 graph for 1920 to 1961, (from almost forgotten old data) and then splice on Keeling's Mauna Loa CO2 curve to bring it up to date, I suspect it is fairly similar to the SST graphs you have supplied.
The 1940 peak is there, anyway.
Implication: ocean warming may be releasing CO2 and we may be a bit irrelevant?
Suspect you are right, El Nino is the main driver. For another, perhaps working in tandem, that explains the geography of the main areas of global surface warming as per GISS etc., see

I think deep geomagnetic flux shifts (of core-mantle boundary origin)may be the driver there, simply on the maps match.
Ian Plimer thinks El Nino may be driven by bottom heat. Maybe? Up current in the South Pacific Gyre is the hottest seabed region we have, by seismic velocity data. Get back if so inclined. Anyone else, ditto.
