The beach is much wider now than it was in the 1950’s, and there is no indication of any sea level rise over the last 60 years at Miami Beach.
1950’s
Claims that Florida is drowning are complete nonsense, spread by snake oil salesmen.
Disrupting the Borg is expensive and time consuming!

This is relevant because Al Armist Gore says Florida will sink first
A common theme of alarm is that coastal cities will flood. Observe how much the infrastructure has changed in the period covered by the photos. In 100 years from now, several more infrastructure cycles will have been completed.
It looks like a road was built between the buildings and ocean, likely on landfill. With that said, no visual evidence of sea level rise.
Just found this, it’s actually the boardwalk, there’s only Collins Avenue along the view shown.
Floods are coded into the Jungian methylated genetic memories of everybody’s “junk” DNA. So is the Devil.
Steve has a guilt complex, of some boring sort. But beyond that, he is a PR genius for loudly distinguishing between types of self-proclaimed skeptics, in his own way.
You are a true idiot spouting idiotic things that make no sense to intelligent people. What are you self-proclaiming yourself to be?
A pseudo intellectual who compensates for his ordinary mind by sprouting what he thinks is clever sounding gibberish.
Looks like the 1950’s pic was taken at high tide and modern one at low. Not sure, but I doubt fill was brought in because fill is dirt and dirt washes out to sea immediately. Fill that won’t wash out would be rip-rap or large rocks to protect beaches, with sand on top, but I don’t see any rocks here. This is just a sand bar.
I would guess the opposite, the recent view is at high tide.
I think the breakwaters are somewhat to explain for the retention of sand on the beaches. But. like you, I see no discernible sea level change.
Miami Beach spent $64 million to restore the beaches with offshore sand from 1976-1981.
There are millions of people living near the shore. Don’t you think someone would noticei if there was meaningful sea level riise? Why should there be sea level rise anyhow with worldwide ice very close to long term normal.
Andy, because North America is a plate floating on magma. Until a few thousand years ago there were 2 miles of ice on the upper half of the plate. When the ice melted, the upper half had to rise and the bottom half had to sink to level out. Like a frog jumping off a board.
Europe is doing the same thing. Finland is rising and Italy is sinking.
Except the ice isn’t melting, it’s increasing……dramatically.
FL has countless oceanfront restaurants and hotels. You can visit any 50 y/o restaurant and see for yourself there has been no noticeable encroachment from the sea.
Here’s a NOAA page that includes a map of water depths around Florida

Apparently the tide gauge data stops in 1982:

Steve: Check out the before and after beach replenishment pictures for Miami Beach at this link:
http://en.wikipedia.org/wiki/Beach_nourishment
It’s absurd to draw any conclusions about such pictures. Globally sea level has risen about 10 inches in the last century, but local conditions (settling, pumping water from aquifers, glacial isostatic rebound, plate tectonics, winds) mean that different locations will experience different amounts of SLR.
No change in sea level in La Jolla, CA since 1871
Gravity pulls tide gauges down. You think you know things which you don’t actually know.
Unless you know what time and date those pictures were taken it means absolutely nothing. Oh, and a foot of tide change would be a lot less visible on a steep change like that than a very low ratio drop off on a beach.
Miami Beach is a sand bar or barrier island. Barrier islands shift around faster than Lindsay Lohan. One hurricane can ruin your whole day on a sand bar.
My link above shows that the sea level has NOT risen 10 inches per century in Miami Beach. More like 3 inches. Nobody cares about 3 inches, just ask your wife.
I recommend that you go look all the Florida tide gauge trends. http://www.psmsl.org/products/trends/
Here’s a plot of the 3 PSMSL tide gauges in Miami (Joined using 2 stations from the keys):
(seasonal cycle removed)
They show a sea level rise of 2.3 mm/yr. Individually they also have positive trends and they match up near perfectly with the RSL curves from the keys.
The link to the plot is

Gravity pulls tide gauges down over time.
All these five gauges measures sea level relative to a fixed benchmark. In case of the Miami beach tide gauge record, then it is referenced to this particular benchmark:
http://sflwww.er.usgs.gov/eden/benchmarks/benchmark.php?benchmark=WCA3-BM6
http://www.psmsl.org/data/obtaining/rlr.diagrams/363.php
Nothing is fixed on this planet. Land moves.
4 SL gauge records for the whole Southern Hemisphere. And Fort Denison is showing 0.25 to 0.5 mm per year SL rise. An inch or two per century. The 5 million people in Sydney wil be most relieved after the Tsunami like predictions of Tim Flannery et al and National Geographic.
My father was a seventh generation Floridian, and I have many family members who live there, some on the coast and a couple along the canals of Coral Gables. They have noticed zero sea level rise. They do report shifting beaches, due to erosion, but no evidence of any rising seas. My uncle had condos in the Keys, right on the water, and again reports zero sea level rise.
Subsidence is a real issue along many coastlines, and Florida’s coasts are full of present day and ancient mangrove swamps, which do subside over time. When property values in Key West and Miami Beach plummet, then I will be concerned.
With beaches that wide today, and that short in 1950, either those pictures were taken at opposite tide levels, or they have added sand to the beaches, or seal levels have fallen quite a bit.
Which do you chose?
Apparently you don’t know that Miami Beach was built over a 5 year period from 1976 to 1981. Here is the relevant text:
“The 10 miles (16 km)–long shoreline fronting Miami Beach, Florida was replenished over the period 1976–1981. The project cost approximately $64,000,000 and revitalized the area’s economy. Prior to nourishment, in many places the beach was too narrow to walk along, especially during high tide.”

And here are the before and after photos:

Don’t they look a lot like your photos.
