Sea Level Rise Hits Florida

Is sea level rising?

With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century. In the United States, almost 40 percent of the population lives in relatively high-population-density coastal areas, where sea level plays a role in flooding, shoreline erosion, and hazards from storms. Globally, eight of the world's 10 largest cities are near a coast, according to the U.N. Atlas of the Oceans.

Global sea levels are and have been increasing at a low rate for several thousand years, since they slowed down at the end of the last ice age, ~12,000 years ago.
Near Miami, Fl the sea level is recorded as increasing at .96 feet per century since before the major CO2 increases on the 1950's.
Were CO2 a major factor in sea level rise, we should see a strong inflection point where the sea level started accelerating, we do not!

[h=2]New Study: Sea Level Rise Doesn’t ‘Spell Doom’ – Little To No Loss Of Coastal Wetlands Projected By 2100[/h]By Kenneth Richard on 17. September 2018
Another new false-alarm paper reveals that coastal wetlands may not only persist well into the 21st century despite present rates of sea level rise, but the coasts may expand and even prosper due to the natural ability for soil to “build up vertically by sediment accretion”. Headline/image source: Sciencenews.org “Coasts are growing all over the world” Two years […]

At the edges of the Glades in salt and marsh waters. First, at the coast, red mangroves. They have the big loopy roots. Then, behind them, black mangroves. These have root nodules that stick up out of the ground like pencils from the mud. Then, behind those, white mangroves and Bay trees. Those are similar but only the leaves of the latter are a spice. After that, we get into fresh water species and the wetlands that are the Glades. No mangroves grow in the interior of the Glades. The salt/marsh and fresh water barrier is maintained by sea level and water flow that constitutes the River of Grass from the Lake to the south.

Mangroves are an important ocean estuary and erosion prevention. They're destroyed large scale for shrimp farms. Though, not in Florida; we have strong environmental laws protecting our natural resources. We also don't off-shore drill, which devastates estuaries elsewhere.

Yep. His comment was ignorant beyond pale. But, that is not surprise anymore.

Actually, his description confirms my recollection.

And, the article describes how something completely different is happening today. Gee...whodda thought?

So where is the required change in slope of sea level rise in the data?

Right around the time on the X-axis when we start seeing more blue above the black line than below it. :roll:

So the 1940's , the 1980's, and starting about 2015?
Nope, Sea level rise is noisy and cyclical, we have no way to tell if the current slight change is any different than the past two changes.
