Eustatic sea level change refers to global changes in sea level caused by changes in the volume of water in the oceans or changes in the shape of the ocean basins. These changes affect the entire planet uniformly. The primary drivers of eustatic change are variations in the amount of water stored in ice sheets and glaciers (thermosteric sea level change due to changes in water temperature), and changes in the volume of ocean basins due to tectonic plate movement. For example, during glacial periods, large volumes of water are locked up in ice sheets, lowering global sea level. When these ice sheets melt, as they are now, sea level rises globally. Similarly, tectonic activity can change the shape of ocean basins which can affect global sea level.
Relative sea level change, on the other hand, refers to local changes in sea level relative to the land. This means that the change is specific to a location and isn't a global phenomenon. Relative sea level change is a consequence of both eustatic change and local factors influencing the vertical position of the land. These local factors include tectonic uplift or subsidence (land rising or falling), isostatic rebound (the rise of land following the removal of ice sheet weight), sediment deposition and compaction, and changes in ground water extraction and storage. For example, land subsidence due to groundwater extraction will result in a relative sea level rise, even if the global sea level remains unchanged. In coastal areas, the effect of eustatic and relative sea level changes can be combined and even amplified.
Eustatic sea-level change is a global phenomenon caused by variations in ocean water volume. This can result from thermal expansion due to increased ocean temperatures, changes in ice sheet mass, or changes to the shape of the ocean basins through tectonic activity. Conversely, relative sea level change is location-specific and reflects the interplay between eustatic change and local land movements. Processes like tectonic subsidence or uplift, isostatic rebound, sediment compaction, and groundwater extraction can significantly influence relative sea level trends. It is essential to distinguish between these two phenomena, as their relative contributions to sea-level change will vary considerably depending on geographic location and specific local conditions.

The prediction of sea level rise at a zip code level requires a sophisticated understanding of local geomorphology, regional oceanographic conditions and sophisticated numerical modeling, incorporating parameters such as glacial isostatic adjustment and thermal expansion. Global models can provide a general picture, but high-resolution projections at a zip code level necessitate the application of advanced computational techniques and in-situ observations. Therefore, access to such specialized data is frequently restricted to governmental agencies or research institutions dedicated to coastal and climate science. Publicly available data often lacks the necessary spatial resolution to provide reliable predictions for individual zip codes.
Sea level rise projections vary significantly depending on location, and precise projections for a specific zip code over such long timeframes require highly localized modeling that's often not publicly available. Factors influencing projections include the rate of global warming, ice sheet melt, and local land subsidence. National and international organizations like the NOAA (National Oceanic and Atmospheric Administration) and the IPCC (Intergovernmental Panel on Climate Change) provide global and regional sea level rise projections, but these are typically at coarser resolutions than the zip code level. To get a more localized estimate, you would need to consult local government agencies, coastal planning organizations, or environmental research institutions in your area. They may possess higher-resolution models or data incorporating local factors specific to your zip code's coastline and geography. Be aware that even these more localized projections come with uncertainties given the complex nature of sea level rise prediction. Always consult multiple sources and interpret the results with caution.
