Coastal flooding created thousands of climate refugees.

As the oceans rose, it brought many problems.   Hundreds of cities were rendered uninhabitable as saltwater seeped into the water tables. The declining population flocked inland to communities that were still liveable, a migration known as the coastal exodus.  This precipitated overly dense residential zones, a breeding ground for drug abuse, violence and other forms of urban decay.

Although most cities fell into disorder and chaos, a few communities thrived in this period of anarchy, most notably those in Scottsdale and Alpine.
