A new analysis of global tidal gauge data by Jevrejeva et al (2014) suggests that the increase is less than 2 mm per year since 1970. That is an inch every 13 or 14 years or 7 inches per century. There are definitely substantial regional variations and there is even more local variation due to land settling or rising - isostatic changes. I believe what is more significant for Miami is waterfront development and the diverting of tidal flows from some areas into others, extraction of groundwater and the sheer mass of structures on the shoreline.
