Great flood

A great flood marked the end of a planet-wide ice age on Kamino ages before the onslaught of the Clone Wars. The massive increase in thermal energy caused the melting of the Kamino's ice caps, submerging the entire planet under a vast ocean. The native Kaminoans, who had not yet developed sophisticated space travel technology, decided not to petition for aid from the distant Galactic Republic, for fear of colonization. Instead, they turned to engineering to adapt not only their flora and fauna, but also themselves to the new aquatic environment.
