Worst case in 50 years is a rise of about 3 feet. There are various maps online that show what that means to geography; this one gives additional info. You can play with different amounts of rise but remember that the higher numbers are based on further into the future.

Also remember that these types of maps show areas that can become permanently flooded. Additional areas will fall into 100-year flood zones and become more susceptible to occasional flooding and higher insurance costs.
It will be many decades before there can be several feet of sea level rise.
It will also be many decades before we could stop that sea level rise if we stopped adding CO2 to the atmosphere today, because of the 40% increase that's already occurred.
The problem that exists is that nobody knows how sensitive the various environments will be to rising temperatures. It's unrealistic to make a prediction. That does not mean that, if we can't prove what the effects will be, then we shouldn't do anything.
Here's a cool world map, that you can zero in on Florida, or wherever, to see what would result from a sea level rise that you can specify.

It doesn't take much. One reason that FL has so many unique animals is that it used to be an island. What is now the Okefenokee Swamp used to be a shallow sea, cutting peninsular FL off from the rest of North America.
Same as for the last 50 years. In fact, the same as it has for centuries. The sea level at St. Augustine is virtually the same as when they founded the city. St. Augustine is the oldest continuous city on our continent.
Now that is as factual as you can get. As far as the rise by tidal gauges, they definitely are not reliable. One example is San Francisco. They showed a rise of 5 inches in a century. However across the bay in Oakland they had no increase. (A mere 11 miles away.) That is what happens when you smoke pot and take measurements.
There has been no effective rise in sea level in centuries and that can be proven.
I've lived in Florida, and I think the worst case scenario is that it DOESN'T get submerged. The tourist areas of Florida are okay, but the "real Florida" is terrifying.
We have many historical records on sea level rise, taken on tide gauges throughout the world dating back to the mid 1800's they show that sea levels since 1841 have risen 13.5cm (5.3 inches) according to the best tide gauges (those that isostatic rebound is not a factor) show that current sea level rise is 1.78mm per year.
That works out at 3.5inches in 50yrs time at historical sea rise rate, however there is some evidence that sea level rise has slowed since 2004
But look for yourself http://www.jcronline.org/doi/pdf/10.2112...
Keep in mind that the projected maps are only based on elevations and do not account for subsidence and erosion. We really have no idea what the changes will be.
Worst case scenario is that the world will explode long before Florida even begins to be submerged in water due to global warming considering how long it will take that much ice to melt from the poles.
Worst case scenario is that Florida could be completely submerged. Like the skeptics, and unlike Baccheus, I don't trust computer climate models Unlike "skeptics" I fail to see how questions about climate models are good news. Global warming could be worse than suggested by climate models. 50 feet sea level rise in the next 50 years is not close to the worst case scenario.

Where can I see a worst case model that shows annual increase for the next 50 years?
in Florida,
it will sink what else do you want look at the countries near equitor for eaxmples
worst case scenario is this, florida could be one third its size, the mississippe river will be ten miles wide at its widest and everything on west and east coast will be under at leat 20 feet of water. but for this to happen would take a catostrophic event ie. a caldera explosion, a large meteor, or Hillary clinton running for president.
My guess is that it will look rather like this:
