Instead, they only tell us about local, relative sea level changes.

For instance, melting ice can cause land to rebound as weight is lifted, causing relative sea level to fall.

The paper by Tamisiea et al. (2010) examines how the exchange of water between the atmosphere, oceans, and continents can contribute to the water cycle, load the Earth and change its geoid, and cause the annual variations in relative sea level over the global ocean.

As relative sea levels rise from land subsidence (sinking and settling of the soil) and rising global ocean levels (due to thermal expansion and ice melt), there is less of a gap between the ocean and our infrastructure.
