The population decline would represent 12–23% of the population of these cities, the study states. The aftermath of such a decline will bring “unprecedented challenges,” the study explains further.
These cities could face a loss in basic services like transit, clean water, electricity, and internet access. Furthermore, an issue depopulation poses is a “dwindling tax base” that would certainly impact basic city services.
raise taxes on the dwindlers
I think they’ll have to.
Imagination
They are going to be under water by then anyway

The second part was a climate joke
As the rest of it. Urban flight isn’t a permanent thing. It comes in waves. Once baby boomers selling homes becomes a thing, city prices will start to drop

Or cut unnecessary/ineffective programs.
Poor political leadership, allowing the quality of life to degrade to the point that citizens are motivated to seek a better option.
The cockroaches are abandoning motel! 
Either Road Warrior or WaterWorld.
DC will be the second city to sink. (NOLA will be first.) Both are swamps waiting to get filled.

Cool cheese-eating urban libs finally admitting to themselves
“I’ve been lying to myself all these years. City life basically sucks. Always has. Always will.”
I wish there was a way to measure attitude based demographics. I think there may be character traits that align with who stays vs who leaves.
Visigoths, Vandals, Barbarian Kings.
