People really don’t understand how large these metros are. Millions of people, millions of homes. Billions in the economy. New Orleans was much smaller.
Just checked. Metro Miami is 6200 sq. mi. with an average elevation of 6ft and the highest point of land is 42ft above sea level and a population of 6 million. That's really really bad.
Swiss Re did a study where they estimated that if Hurricane Andrew happened again and hit Miami, it would cost in the neighborhood of a quarter trillion dollars.
That was in 2017, so that number has gone nowhere but up.
Cons are gonna deny climate change all the way up until the Port of Houston takes a direct hit from a Cat 5. And even then they’ll still argue against it from underneath a 20 ft storm swell.
