New Orleans levees passed their first major test
As the article rightly points out, levees will do nothing for a slow moving hurricane like Harvey that dumps tons of rain or for a large cat5 hurricane with storm level surges that are much higher than Ida. The place is sinking while sea level rise is already locked in with current levels of CO2 in the atmosphere. The only solution is relocation, but nobody wants to hear that. It is an inevitability that New Orleans will be uninhabitable. The only question is when.
