Antarctic ice loss driven by faster-flowing ice streams and by warmer ocean waves lapping at the bottom of ice shelves

Led by investigators Andrew Shepherd of the University of Leeds and Erik Ivins of NASA, they believe that the loss, now up to 219 billion metric tons per year, is driven both by faster-flowing ice streams and by warmer ocean waves lapping at the bottom of ice shelves.

How Scientists Tracked Antarctica's Stunning Ice Loss
If this is all true as research shows, how much higher will sea levels rise and how fast are sea levels going to rise worldwide? How fast will coastal cities be inundated because all oceans are connected worldwide. Just look at any map of the world. As sea levels rise ALL coastal cities will be inundated equally from the Mediterranean ocean to the Black Sea to New York and Miami, and Dhaka and Chittagong in Bangladesh as well as Venice,Italy.
If Antarctica is now melting many times faster than 5 years ago how fast are all coastal cities worldwide going to be inundated? And should richer countries build cities further inland to compensate in the future while poorer countries just have to abandon their cities completely?
Also, for countries like Bangladesh and for places like Florida this just means it won't be very long before whole countries like Bangladesh and most of states like Florida will be almost completely underwater with places like Miami gone completely except for the taller buildings of two stories or more.
For example, the highest land levels presently in Florida are ONLY 75 feet above sea level. And it only takes about 10 to 20 feet of sea level rise to put the most well traveled roads in Florida underwater at some point in their journeys.
