I saw an interview with an urban engineer in Louisiana talking about how climate change is already causing damage across coastal towns down there. The salt water from the ocean is coming farther inland than it's supposed to, contaminating nearby fresh water sources. But what's really a problem is how saltwater gets into cities' pipes, causing corrosion. Entire buildings have become unusable because pipes no longer do their jobs.

Cities don't have enough money to build/repair seawalls/levees nor can they replace pipes. So it's only a matter of time before historical sites in Louisiana are abandoned completely and left to rot. And the problem gets worse as more people leave and fewer tourists visit because the state is in a death spiral.

Any sensible government would step in and help, but of course this is Louisiana so that's a gommunism and the free market will solve the problem on its own.
