I've recently read that sea level is rising about 2.6-2.9 millimeters per year.  in 84 years, that would be 0.231 meters, or a bit less than one half foot.  Where do you get the "a minimum of 3 feet"?   

A book called The Flooded Earth by Peter Ward, an astrobiologist with NASA.  But there are lots of places on the net that quote similar numbers -
