A line of makeshift shelters fringed the hillsides above the city. Outside crude shacks groups of people sat facing the sea, looking out at ominous signs of turbulence which been a familiar part of earlier lives. Many had experienced rapid costal land erosion where homes had once been.  Some had been fortunate escapees from rogue tides and surging waves that had wiped out people, dwellings and, often, all means of surviving. People had fled for their lives, joining the worldwide population of climate refugees in search of safety and clean water.
