I'd be interested in an explanation as to why sea level would rise more some places than others. It seems to me it should raise pretty much the same everywhere because gravity.
Also, sea level is determined by a number of factors including astronomical and predictable, like moon, sun and other planets gravity influence, or random meteorological events like winds, low or high pressure systems and land mass configuration. All these contribute to the tide cycle and the sea level anywhere in the globle.
For example, there are places in the world with huge tide amplitudes like 12 m or so and other with no tides at all (excluding meteorological events).
The problem is the "mean sea level rise". The "mean sea level" is usually determined by and average of at least 19 years of measurements of the sea level, which is approximately the time it takes to complete a full moon cycle.
Another is that polar ice, through its gravitational pull, pulls water in the direction of the poles. If it melts, it (on average) moves away from the poles, decreasing that pull towards the poles.
For example melting freshwater ice not only adds volume to the ocean, it also adds mass, and changes salinity, which changes temperature, which itself affects volume, and also influences ocean circulation patterns.
And since winds are powered and directed by heat energy in the atmosphere, changing the amount and/or pattern of heat in the atmosphere will also change the wind patterns.
The shape of the ocean floor is slightly affected by the weight of the sea water on top of it. Changes in sea water distribution due to other factors might also result in changes in relative ocean basin depth--areas with more water mass will depress the crust a bit farther into the mantle; while areas with less water mass will rebound slightly.
There are other factors, such as the cold/warm water cycle creating very slow currents that push water towards certain landmasses.
But as I understand it, gravity is the main cause.

Winds and tides are other significant factors, both of which can vary strongly regionally and globally.
"It looks like Kwajalein is affected by a local subsidence induced by building construction (or some sea level “correction” in order to have it going up). The Majuro records, for sure, contradicts any (sic:"and") acceleration claim; even a general “rise”.

Sea surface height (SSH) has been measured from space with great accuracy, using radar altimetry, since 1992. We can now also measure sea surface temperature (SST), salinity (SSS), and surface winds. The winds are knowable because wind ruffles the water surface and this changes the radar scatter properties.
Therefore, somewhat surprisingly, we know more about the ocean than the land.
