The streets flood even without storm, rain, wind, even on a calm sunny day. It didn’t used to happen, but now the highest spring tides of the year (around October) bring flood waters, septic systems back up, waste oozes onto streets and lawns, saltwater leaks into groundwater and spoils drinking supplies. It’s not a pretty sight, and it’s not confined to Miami and New Orleans, it’s all along the coast.
It’s an undeniable sign sea level is rising. But one wonders: how fast?
