Left unmentioned in this article is the FACT that as a major metropolitan area, Miami and its neighbors has been pumping out ground water for DECADES! Over-pumping beyond recharge rate is a known cause of land subsidence and thus a contributory causation of flooding.
I am not for a minute saying that this is the sole reason for flooding in the area but this reporter failing entirely to mention this little tidbit seems to show a single issue concern, perhaps from some briefing papers?
Indeed it is, and what few people mention is that the more water you pump out, the more dissolution of the underlying limestone which occurs, and therefore more sinkholes, and a lowering of the ground. The general land under Florida is getting lower, not just the sea level rising.
