The reason for a lack of short term correlation is probably that, absent a volcanic eruption, the Atlantic is warmer during an El Nino BUT the wind shear is greater, thus destroying,
on such occasions, the agreement you would normally get with multidecadal changes in SST in the Atlantic RELATIVE to other
ocean basins.
Whether the

We need to be careful focussing upon «trends» — it can lead to serious errors of context — and this underlies the entire «global warming» thesis which relies upon computer models with entirely false (i.e. non-natural) notions of an equilibrium starting point and calculations of trend — this conveniently ignores cycles, and it has to because a) there are several non-orbital cycles in motion (8 - 10 yr, 11, 22, 60, 70, 80, 400 and 1000 - 1500) depending
on ocean basic, hemisphere and global view — all interacting via «teleconnection» of those
ocean basins, some clearly timed by solar cycles, some peaking together; b) because the cycles are not exact, you can not tell in any one decade where you are in the longer cycles.

on stats, including hemispheric & global ones.
b) volumetric effects — change in the volume of water contained in the
oceans and the geometry and areal extent of the
ocean basins c) gravitational effects — change in the gravitational attraction of the earth (induced by deformation), by the change in distribution of ice and by the change in self - attraction of the water d) rotational effects — change in the moment of inertia caused by a change in the distribution of mass within the earth and
on its surface.
