Climate change could bring flooding throughout Fort Lauderdale in next century

FORT LAUDERDALE The city that calls itself the Venice of America will become increasingly like its namesake as sea levels rise over the coming decades, experts predict.More and more residents will find their neighborhoods and streets flooded, environmental officials warned city commissioners Tuesday. Low-lying areas like posh Las Olas Isles will experience the brunt first, but much of the eastern portion of the city as well as downtown will be affected within the next century.
Environmental agencies project the ocean will rise in the region between 2 and 5 feet by 2100 as a result of global climate change.
Sea level has scarcely changed in Miami this millennium.
Yep, and notice the discontinuity. I’m not sure, but I’d say there are 3 different gauges. And just eyeballing, I’d say from 2000-2006 the overall trend would be nil or lowering. But, something changes. Suddenly, the temp gauge starts at the lower end of the spectrum…….naw…. I’m sure it was all on the up and up.
bingo….you win!
This was the gauge at Virginia Key, you know the Seaquarium….
Bernie Lavine moved parrot jungle from south Miami out of Virginia Key and bought that property. They had to move the gauge.
In 2006 they moved the gauge from the VK location back to Rosenthiel.
Which, because of where it’s sitting, gets huge tide changes…..
Sometimes, I hate being right. No caveat to the new starting point, Nothing…..well, it may be documented in some obscure text file that I haven’t read yet,………….
This tidal study…………. they are as bad as the thermometers…… worse.
Thanks Lat.
I thought Florida was swamp and sand bars. That would make it susceptible to soil compaction.
The average elevation in Florida is said to be 98 ft but the mean of the elevation in Florida is also said to be 100 ft. The highest point in Florida being 345 ft is lower than from the road in front of my yard and my back property line.
I have a 640 ft elevation change from the lowest point to the highest point on my property.
Latitude:
Maybe you can help here with the true average elevation.
Most of the cities I found there have elevations lower than the grade from my house to the road!
Mike, I have no idea what the average it….
Britton is the highest, 345, but that way up in the pan handle, south Alabama.
The highest on the peninsula is at Bok tower, I think that’s about 300.
Compaction depends on where you are, there’s a limestone ridge that runs down the center west of the state, and even most of the everglades river of grass is also on limestone.
I had though Florida to be built from eroded material that was washed from the Appalachians like many of the coastal regions are. The possible projection maps for sea level rise tend to show a more dramatic loss of land in Florida as if most of the state is near sea level.
The sea level rise maps are a flat out lie…..you knew that LOL
The next island south of us is 19ft above, yet they show a 2 ft rise covering it.
Most of Florida is limestone, coral reef
Thanks for that!
to give you an idea…
We as as far out on the edge of this island as you can get and only about 20 ft back from the edge of the water…..
….yet our foundation is 11 feet above mean high tide.
We’re sitting on an old solid coral reef……………
I thought the Keys were like the Barrier Islands or were a part of the Barrier Islands but I looked up the Geology for both types of “Islands” and now see the difference!
Speaking of Venice, I was there in 1977 and the water lapped at all of the doorstoops with high tide causing areas to be under several inches of water.
Since I haven’t heard reports of Venice installing moorings for submarines, I wonder how their sea-level situation is?
I’ve owned waterfront property for the last 48 years on the Gold Coast [Australia] which is modelled on FL [only a cheaper] and a 60 meter, estuarine sea wall I built on alluvial sand [still straight and true], I check at the highest astronomical tide each year to see if these SLR predictions are observable.
In spite of channel widening and deepening between the wall and the ocean over that period which would only increase these tide levels, these HATs are actually falling.
I don’t claim that this is very scientific but if my SLR hasn’t done anything observable in around 50 years, FL hasn’t got too much to worry about.
When they dredged the channel you were supposed to add the additional depth to show the true height. Deeper channels mean higher sea level!
It is a GIA Science thing! š
There was actually a peer reviewed paper claiming this!
Oh NO!
I’m 0.3 mm out!
But actually, if I multiply that by 48 [about 5/8 of an inch] I’m still down near a foot.
To do it right you do not take the global average you would have to use the actual at your location. Example: If they dredged the Channel 3 meters lower you need to add 3 meters to the sea level. Got it? š
I have relatives who live along the canals of Coral Gables and they have seen zero change in water levels in over sixty years. Not one home has been abandoned or bulldozed.
Gator, tell them where they can really tell is at the old concrete dock on Riviera.
It was built in the mid ’20s, only 6 inches above high tide, so the ladies didn’t have to step high to get out of the boats……
….it’s still 6 inches above high tide, almost a century later
It is magically rising to keep pace with the expected sea level rise so you need to apply GIA to figure the real sea level at that location! š
Just like the float in a toilet bowl but it does not go down!
