South Florida Has A Nightmare Scenario From ‘Climate Change Or Something

Yet another in a long line of carnival barker prophesies

The Nightmare Scenario for Florida’s Coastal Homeowners
Demand and financing could collapse before the sea consumes a single house.

On a predictably gorgeous South Florida afternoon, Coral Gables Mayor Jim Cason sat in his office overlooking the white-linen restaurants of this affluent seaside community and wondered when climate change would bring it all to an end. He figured it would involve a boat.

When Cason first started worrying about sea-level rise, he asked his staff to count not just how much coastline the city had (47 miles) or value of the property along that coast ($3.5 billion). He also told them to find out how many boats dock inland from the bridges that span the city’s canals (302). What matters, he guessed, will be the first time a mast fails to clear the bottom of one of those bridges because the water level had risen too far.

“These boats are going to be the canary in the mine,” said Cason, who became mayor in 2011 after retiring from the U.S. foreign service. “When the boats can’t go out, the property values go down.”

If property values start to fall, Cason said, banks could stop writing 30-year mortgages for coastal homes, shrinking the pool of able buyers and sending prices lower still. Those properties make up a quarter of the city’s tax base; if that revenue fell, the city would struggle to provide the services that make it such a desirable place to live, causing more sales and another drop in revenue.

And all of that could happen before the rising sea consumes a single home.

Oh noes, doom! Even before doom!

Of course, what’s missing from this very long thinly veiled press release from the Cult of Climatology is the data on actual sea rise, which is standard operating procedure. The best data for long term sea rise comes from Mayport, Florida,  which shows just 2.55mm a year, equivalent to .83 feet over 100 years. That’s low for a Holocene warm period.

In fact, it’s damned hard to find any hard measurements on sea rise in the South Florida area, especially long term. It’s almost like they don’t want anyone to know. Realistically, the S. Florida coast isn’t that far above sea level, some reports put it around 3 feet. So, if one is going to build, one might want to think about where they are building.

    From the graph you supplied, the mean sea level has increased 6 inches since 2000. That’s about a foot every 15 years, provided the rate doesn’t increase. We understand why you prefer to use the modeled 100 year average.

    Do you think the politicians, the insurers and the scientists are all wrong?

    Why do you think the sea level is increasing?

    • According to the baseline trend, you’re wrong. At 2.55mm per year, that’s a rise of 1.5 inches in 15 years. Math.

      What’s causing it? It’s a Holocene warm period. The changes are primarily natural, just like during the previous warm periods.

      Why do you think math is so hard, little guy?
      One would guess reading comprehension isn’t your strong suit either.

  2. Jeffery says:

    Teach: As I pointed out, you used the trendline, ignoring the rapid rate increase in the past 15 years or so. Perhaps you’re right and the rate will slow down. Math.

    What are the “natural” causes of the changes? Scientists who study such things disagree with you.
