Sea-level rise can mean that saltwater intrudes into groundwater drinking supplies, contaminates irrigation supplies, or overruns agricultural fields low-lying, gently sloping coastal areas are particularly vulnerable to contamination of freshwater supplies. Understanding past sea level is important for the analysis of current and future changes in the recent geological past changes in land ice and thermal expansion from increased temperatures are the dominant reasons of sea level rise. Projections of sea-level rise global sea-level rise is caused by two main factors: thermal expansion (ocean water warms and expands), and the contribution of ice sheets (eg, from glaciers, land-based, ice sheets, and sea ice) due to increased melting.

The terms local or relative sea level refer to both the global change in sea level and the effects of land motion where the land is sinking, the rate of relative sea level rise is larger than the global rate. Other human impacts can decrease sea level rise, such as building dams and artificial reservoirs to store water when people use wells to pump water from underground reservoirs, that water eventually reaches the ocean but none of these are capable of influencing sea level to the same extent as thermal expansion and the melting of large.
