  1. Even if all ice on earth melted sea level will not rise more than 2 meters. Floating structure does not work for heavy industry nor high density residential. Singapore just don't have enough space for a sprawling floating city. For now importing sand is cheaper if that become a problem then the next less expensive solution is to put their industry underground.

  2.  @volkhen0  There is not enough ice to cover the entire earth with additional water 70 meters high. Ice is less dense than water so if your projection is true then the equator should be covered right now with more than 70meters of ice. Just look at the surface area of the earth covered in ice that is a tiny fraction compared to the entire surface of the earth. Also yes a significant portion of the polar ice cap has melted already. And don't expect the sea level to continue its rise indefinitely the volume of ice on earth is not infinite.
