New Orleans had long been in decline.

It boomed in the 1830s and 1840s

It recovered from Civil War but was in decline in 1950-1960s.

Much of the city was built on drained swamp land. The land sank and was then below sea level. Nothing to do with climate change. It was swamp land 250 years ago before combustible engines.
