It can absolutely happen, yes, but note that this is nothing that anyone alive today will witness (barring progress in life extension technology). Sea level rise is projected to be around 2.4 meters by 2100 in the worst scenarios. Maybe it'll be a bit higher than that but not by much. And by the time the oceans do rise by that level, maybe we'll have reclaimed most of the continental shelves anyways by building dams, so we'll have a firm grip on the technology needed to build dams at scale. There are far graver consequences of climate change that affect humans immediately, this decade, this year, this century.
