You make a very big assumption - that people don't care about Miami, a city with global name recognition and so on...

I also assume you are not on Instagram, where Miami is huge - it's the 6th global instagrammed city, second US one (London, NY, Paris, Dubai, Istanbul, Miami, LA) - https://www.statista.com/statistics/655550/most-hashtagged-c...

Instead of shorting it you might want to long "defending it".

Please help me understand how care and instagram pictures are going to stop rising water?

The only thing that may help is quickly lowering CO2 emissions worldwide. I think no amount of care, willpower or even unlimited amounts of federal money can save Miami otherwise.

You say that as if Miami's current popularity will preserve through global climate change. I don't think Miami can "defend" against the earth's inevitable climate change for better or worse.

It's going to be pretty hard to defend it. It's built on porous limestone. So water's going to bubble up everywhere - not like defending NYC

I think he means invest in seawall manufacturing companies, as opposed to some bizarre financial instrument that allows you to profit from the demise of an entire city.

As parent mentioned Miami can’t be protected with sea walls because the geology allows water to seep up and will drown the first floor of buildings with any sea level rise

I read an article the other day about how Miami residents are mostly not concerned and seem to hold up other places such as Rotterdam who are doing a good job dealing with these issues but not understanding that Miami's geology and hydrology is vastly different and is going to leave them seriously screwed.
