Enormous & Accelerating Threats Stacked Up For Florida - Sea Level Rise Just One Of Them
EDIT
Sea level rise
The threat: By any estimation, Florida is drowning. In some scenarios, sea levels will rise up to 31in by 2060, a devastating prediction for a region that already deals regularly with tidal flooding and where an estimated 120,000 properties on or near the water are at risk. The pace of the rise is also hastening, scientists say – it took 31 years for the waters around Miami to rise by six inches, while the next six inches will take only 15 more. At such a rate, many of Miami Beach’s landmarks, the world famous South Beach, and the picturesque art deco hotels of Ocean Drive, will be lost within three decades, according to some studies.
Possible solutions: Dozens of municipalities, the four counties of south-east Florida, and partner groups such as the Nature Conservancy have combined their efforts through the south-east regional action climate plan to tackle the crisis. In Miami Beach, dubbed the “ground zero” of sea rise, a multifaceted and costly Rising Above program is already under way. It includes elevating roads, building new sea walls and installing new and higher capacity pumps and drainage systems to alleviate flooding. In the Florida Keys, the approach will probably tilt more towards managed retreat: abandoning areas too expensive to maintain and focusing on measures with a better cost-benefit ratio. Parts of the Keys are going to simply disappear, some within two decades.
Water contamination
The threat: Saltwater from sea level rise is seeping further inland through Florida’s porous limestone bedrock and contaminating underground freshwater supplies, notably in the Biscayne aquifer, the 4,000-sq mile shallow limestone basin that provides drinking water to millions in southern Florida. Years of over-pumping and toxic runoff from farming and the sugar industry in central Florida and the Everglades have worsened the situation. The Florida department of environmental protection warned in March that “existing sources of water will not adequately meet the reasonable beneficial needs for the next 20 years”. A rising water table, meanwhile, has exacerbated problems with south Florida’s ageing sewage systems. Since December, millions of gallons of toxic, raw sewage have spilled on to Fort Lauderdale’s streets from a series of pipe failures.
Possible solutions: A comprehensive 30-year Everglades restoration plan was authorized by Congress in 2000 to “restore, preserve and protect” the south Florida ecosystem by improving water flows to help flush the salinity, and a 78bn-gallon Everglades agricultural area reservoir (EAA), a key component of the congressional plan, is earmarked for land once leased by big sugar. The restoration plan, however, has stalled amid funding wrangles, and the storage reservoir plan delayed several times.

And, of course . . .
Politics
The threat: Florida has long been plagued by political leadership more in thrall to the interests of big industry than the environment. As governor from 2011 to 2019, Rick Scott, now a US senator, slashed $700m from Florida’s water management budget, rolled back environmental regulations and enforcement, gave a free ride to polluters, and flip-flopped over expanding offshore oil drilling. The politician who came to be known as “Red Tide Rick”, for his perceived inaction over 2018’s toxic algae bloom outbreaks, reportedly banned the words “climate change” and “global warming” from state documents.
