If all ice melted sea levels would rise 270 feet ! That’s not taking into account affect of currents , in which case it would rise more in some areas and less in others . However , for the sake of arguments let’s say it’s a uniform 270. My house elevation is 280 and elevation here varies , dropping under 200 only a few miles east and south east. I would literally be an island on the coast ! Raleigh would be the new coastline . Of course that’s not taking into account the fact rivers would flood and make sounds and estuaries so it’s possible Raleigh would be underwater too. Ocean however would be around here ! Man oh man dream come true !
