“The thing with the real beaches is, you got to pay flood insurance. I don’t have to pay flood insurance in the middle of Florida here, so it’s a lot cheaper,” said Svoboda.

We live beachside 800 feet from the Atlantic Ocean and we don't have flood insurance and our mortgage lender does not require it. You need flood insurance when you live in a flood zone (other than X). Your flood zone depends on your likelihood to flood.

Building a giant swimming pool is an interesting idea, what could possibly go wrong?

So some “leading expert”, Harold Wanless, whoever he is, thinks things will be bad, we all better start stocking up on life preservers now...

We’re not gonna all drown for crying out loud, even if this expert happens to be right.

Don’t get me wrong, it’s hard to argue that man is negatively impacting the planet and the impact gets faster as the bodies multiply. But, if you think we have any reason to believe this guys assertion that the sea level rise will be “x” feet in 50 years, that’s crazy and won’t matter to the vast majority of us anyway. So why is any one worrying about it?

But for those that think this guy actually has this right, you can take comfort in knowing that walls work and I am quite sure that if we need walls, we’ll build walls so we all stay high and dry.

Even if the water rises 3 feet, it will not breach the sea wall at my house which is under construction now. My wall will still be working just fine in 50 years. Worry? Not me.

Wanless analyzes the empirical data that shows sea level rise is accelerating. Only in recent years have temperatures in Arctic and Antarctic increasingly exceeded the melting point of ice. Oceans absorb over 90 percent of the excess heat associated with fossil fuel consumption. Warming oceans in the cryosphere especially are wreaking havoc on not only sea ice, but also on land-based glaciers.


Note the steepening of the curve here after 2010.

<<The total heat content of the world’s oceans (OHC) in 2019 was the warmest in recorded human history, according to a January 13 paper by Cheng et al., Record-Setting Ocean Warmth Continued in 2019, published in Advances in Atmospheric Sciences. In the uppermost 2000 meters of the oceans, there were 228 Zetta Joules more heat in 2019 than the 1981−2010 average; 2019 had 25 Zetta Joules more OHC than 2018 (a Zetta Joule is one sextillion Joules-- ten to the 21st power).



“We found that 2019 was not only the warmest year on record, it displayed the largest single-year increase of the entire decade, a sobering reminder that human-caused heating of our planet continues unabated,” said Penn State’s Dr. Michael Mann, one of the co-authors. The gain in ocean heat between 2018 and 2019 was about 44 times as great as all the energy used by humans in one year.

More than 90% of the increasing heat from human-caused global warming accumulates in the ocean because of its large heat capacity.>>

The accelerating calving of Antarctic glaciers will accelerate sea level rise even further.

Wanless has reported his analysis of the facts. E.g., the NOAA's high forecast calls for a foot of sea level rise by 2030, implying levels of sea level rise in this decade much greater than currently.


Sea level rise acceleration already is obvious (90 days of sunny day ocean flooding in Key Largo this past autumn), and will become more obvious with each passing year. We are witnessing record Antarctic temperatures and the Antarctic is in the midst of its summer ice melt season. The resulting sea level rise measurements reported by NASA later this year may confirm Wanless' dire warnings; Wanless' estimates may become widely accepted over this decade.

So the future impacts of sea level rise, whether coastal inundation or higher storm surges, soon no longer will be theory as much as observed reality. And given the federal government's nascent budgetary crisis, it's unlikely that Congress will much longer continue, let alone increase, massive FEMA flood insurance subsidies.


So lagoon developments increasingly may become popular in Florida as alternative to living on or even near the coast.

"The sea-level acceleration rate measured at 0.03 mm and 0.05 mm"

that's 0.0011811 inch to 0.0019685 inch.....1/10th of an inch in 100 years

and here's the actual source....self published....and not peer reviewed > https://scholarworks.wm.edu/reports/1111/

1/10th of an inch in 100 years is impossible to claim....when their error bars are over 100 times greater

It's only been in recent years that temperatures in the cryosphere, especially ocean temperatures, have been continuously increasing above the melting point of ice. So the 100-, 50-, and even 20-year averages are meaningless.


NASA satellite measurements show that sea level increase has been averaging through early October 2019 over 5 millimeters, about 1/5th of an inch, annually for the last 8 years. With record temperatures now occurring in Antarctica and increased glacier calving during the ongoing Antarctic ice melt season, sea level rise may accelerate rapidly through May, with NASA global sea level measurements reflecting this current Antarctic summer ice melt season reported this summer. NASA reports global averages, and as Wanless has explained, due to thermal expansion and gravitational changes as polar ice mass dissipates, sea level rise is higher around Florida.

NOAA's high forecast of a 12-inch sea level rise by 2030 implies well over an inch of annual sea level rise by the end of this decade given the current 1/5th inch rate. So the acceleration of sea level rise should be patently obvious over the next several years. Due to natural feedback loops, not yet comprehended in most projections of sea level rise, possibly overwhelming the impact of mankind's fossil fuel consumption, some expect NOAA and other projections to be too low.

Won't the catastrophic and obvious inundation implied by an inch of sea level rise annually make lagoons developments on higher elevations well away from the shore much more desirable relative to beachfront property?


Home values already are falling in Miami Beach where hundreds of millions are being spent to raise roads and build a massive network of pumping stations in an effort to "adapt" to rising sea levels.

The lagoons technology treats the water, supposedly very efficiently. Also, reportedly foreign objects such as reptiles also are easily detected, according to the marketing materials.


If the marketing hype is accurate -- no bacteria, no amoebas, no reptiles, no red tide or toxic algal blooms -- these artificial lagoons may become preferred residential developments in Florida.
