The research aims to quantify the impact of vertical land motion on relative sea-level rise in densely populated coastal areas.
Synergized diverse vertical land motion data covering 65% of coastal population
Analyzed subsidence rates in densely populated cities and deltaic regions
Studied global relative sea-level rise from 1995 to 2020
Average global relative sea-level rise for coastal populations is 6 mm/year
71% of the coastal population resides in regions experiencing subsidence
Observed rates of subsidence are about twice the climate-driven absolute sea-level rise
