Lillypad City: The floating city that might be the answer for cities flooded by global warming

Callebaut with designs

Vincent Callebaut, an eco-conscious Belgian designer, proposed this prototype for a floating metropolis he has named Lilypad. These self-contained floating city extensions that could be moved to metropolitan areas losing shoreline due to global warming, to absorb up to 50,000 "climate refugees'. 

Wind, solar and hydropower will most likely supply the energy if the city ever comes to fruition, and one could extrapolate that the diverse plant life on each could help maintain bio-diversity in changing climate conditions.
