Sea Level Rise
The ongoing increase in global mean sea level caused by thermal expansion of warming ocean water and meltwater input from glaciers and ice sheets.
Governing formula
Δh_sea = Δh_thermosteric + Δh_eustatic (Thermal Expansion + Meltwater)
SI unit
mm/year (Rate of Rise)
In depth
Global warming causes sea level rise through two primary mechanisms: thermosteric expansion (~40%, warming water expands) and eustatic mass addition (~60%, melting land ice from Greenland and Antarctica).
Examples in the real world
Current global mean sea level rising at an accelerated rate of ~3.4 mm/year measured by satellite radar altimeters.
