If all this really is happening so fast how do we still have people living below sea level.
That appears to defy all logic and reason.
Global sea level has been constant for 11,000-years,until relatively recent times.Global sea level,by definition,defines an Interglacial.The ocean temperature observed today reflects a heat input from 100-years ago.There's that much time lag involved due to the enormous mass of ocean water involved as a heat sink.
As to living below sea level,as long as the crust,between the locality of interest and coastline is impermeable,any topographical boundary in between,will hold the water back.
The 'Queen's Bath',on the big island of Hawaii,would be an example of a permeable coastal area,as with Miami,where seawater can migrate inland,directly through the porous substrate.
