By the same token, a city like Phoenix living on borrowed time due to increasing water insecurity (not to mention an urban form that is so flaccid that you could build single family houses around its downtown and people would clap their hands that the boom has finally returned).
You can't isolate the most epic challenge facing humankind - climate change - from predictions of future urban splendor. At some point, you have to account for something that is already a big black cloud on the horizon. Obviously, it's not just the Sunbelt cities facing this existential threat. But it is in the Sunbelt where too much or too little water will be most pronounced.
Just curious if anyone is concerned about this....

Absolutely, there will be huge effects. Even a few feet of ocean level rise would wreak havoc on much of Florida for starters, and levees wouldn't cover the whole state. Drought conditions will affect water tables and river flows, though Phoenicians(?) say the city itself isn't having a problem. Some areas will get more precipitation. Some more storms.
The common theme will be "different." Crops, trees, and fish that do well in yesterday's climate might not if rain drops 15% and temps go up a few degrees. Ski areas are obviously doing a lot of planning as things have already changed substantially for many of them. In my region that translates to problems with the mountain snowpack that we rely upon melting slowly to create the drinking water we need for the dry summer. And so on.
For cities, this will impact where people want to live, and the financial costs of doing so, which will affect population trends. Much like every penny creates a clear, predictable change in cigarette sales, population migration is affected by every few bucks in the AC bill for example.
