NHC concluded that it is likely that much of the city experienced sustained winds of Category 1 or Category 2 strength. - Wikipedia.
First of all, hurricanes are possible there. There is no connection between global warming and hurricanes.
Hurricane Category 1 or Category 2 brings the mess, but not the mass tragedy. I've been in Miami thru Wilma and Catharina, we lost poser, lost some trees and some people got the house damaged.
The real tragedy came from the flooding, which was a result of broken levees. The government was supposed to properly build and maintain the levees.
The real tragedy comes from is ignorant people, who did not care about taking care about their city, not the whole planet.
This tragedy would happen regardless of the pollution.
