Flydon Maxima

From Tardis Wiki, the free Doctor Who reference

Flydon Maxima is a part of the Flydon Agglomeration, global warming led to an increase in the already rising 88% water surface coverage and led to the commonly used renaming of the planet as ‘Despair’. The rapid rise of the water level lead to the population leaving the planet. Many choose to settle on the nearby smaller planet of Flydon Minima. Others adapted living in floating cities surviving on fish, seaweed and rainwater.
