The depth on the map was over 100 meters. It would multily to about 400 feet lower than it is today. With the ice that is left to melt, it could go 30 feet higher. Goodbye Miami, Keys, Naples, Tampa, etc. Even 6 more feet would be a disaster. A friend sold their property in Miami and moved to Orlando which will be above water for several hundred more years.
But all the current evidence is pointing to a cooling Sun. That means more ice and a receding sea level.
