The strong warming in the polar regions is related to changes in the thermohaline circulation.

The issue with the Mauritsen and Stevens piece is that it tries to go well beyond a «what if» modeling experiment, and attempts to make contact with a lot of other issues related to historical climate change (the hiatus, changes in the hydrologic cycle, observed tropical lapse rate «hotspot» stuff, changes in the atmsopheric circulation, etc) by means of what the «iris» should look like in other climate signals.

Spatial variability of the rates of sea level rise is mostly due to non-uniform changes in temperature and salinity and related to changes in the ocean circulation.

I agree that the application of higher resolution model equipment does not help to reduce the uncertainty range of the sea level in the Amsterdam harbours: assumptions about changes in the heat storage, icecap melting and changes in the gravity field dominate this uncertainty range (although some regiona features related to oceanic circulation and heat redistribution may be better resolved in higher resolution models).

ENSO is ultimately driven by change in sea surface pressure at high latitudes due to the coupled circulation of the stratosphere and troposphere and the inter annual variations in ENSO relate to what we know as the Southern Annular Mode and the Northern Annular Mode.

One last point related to my last post, is the extent / degree of magnitude of a more meridional atmospheric circulation pattern (N.H. especially) could influence snow cover, cloud cover, and precipitation amounts which could set up stronger positive climatic feedbacks, which could then result in an even more significant climatic change going forward.
