Well OK Then

Dozens of luxury condos, hotels in Miami sinking at ‘unexpected’ rates, new study reveals...

Takeaway quote though:

Experts called the study a “game changer” that raises a host of questions about development on vulnerable barrier islands. For starters, experts said, this could be a sign that rising sea levels, caused by the continued emission of greenhouse gases, is accelerating the erosion of the limestone on which South Florida is built.

EVERYTHING is globull warmering. 

Except for the complete lack of measurable sea level rise.

Barrier islands are sand bars.  We didn't use to care about erosion on them and they did what the name said:  They were a barrier to the waves and protected the mainland.  It was only after we started building on them and oceanfront property going stratospheric in value we started noticing how they would be eroded by the water.

I'm willing to bet that building tall buildings on sand is a bad plan regardless of sea level.

PS: They mention that the measured sinkage is within the expectations of the engineers who designed the buildings.
