In fact, outside the realm of popularized alarmism, it is well known that geological processes are more determinative of relative sea level changes than climate factors contributing to sea level rise or fall (i.e., glacier melt or advance).

Piecuch et al. (2018) concluded “the majority of large-scale spatial variation in long-term rates of relative sea-level rise…
