Scientists and designers are proposing radical ways to "refreeze" the Arctic

Led by 29-year-old architect Faris Rajak Kotahatuhaha, the group envisaged a submersible vessel capable of producing 16-foot-thick, 82-foot wide hexagonal icebergs.

The process would begin with the submarine dipping beneath the surface to fill its central cavity with seawater. Salt would then be filtered out, raising water’s freezing point by more than 3 degrees Fahrenheit, after which a hatch closes over the chamber to protect it from the sun.

An iceberg would then form naturally inside, before being ejected a month later. According to the team behind the project, the hexagonal shape may encourage the icebergs (or “ice babies” as Kotahatuhaha refers to them) to interlock with one another and form larger frozen masses.
