Those tou speak of are Silyrian period, so like abput 350 million years old!
There was a large area of the US underwater in what was called the western inland sea. This took place in the cretaceous period. Lower Alabama and all of Miss and La were submerged during this period 100 million years ago. It was due to tectonics and not climate.

It's ridiculous how politicized the fricking weather has become. One side thinks we're destroying the environment with every breath, and the other thinks nothing we do has any effect. As usual, reality is somewhere in the middle. We can stop treating our planet like shite without being told we're assholes for filling up at the pump.

Well...kinda.
And I studied this seaway for my graduate work.
There were multiple seas that covered North America, especially that part of North America.
The one you are referencing is yes, due to plate tectonics (back basin made when Farrallon Plate collided with North American plate forming the Sevier Mountains to the west), but it was also during the Cretaceous, so there was very high temperatures and CO2 levels then, which caused global sea level to rise.
This is called steric sea level rise. Meaning that the ocean molecules are warmer and spread apart (contract for colder). That at there was far less ice on land during this greenhouse period, so sea levels were higher.
What you are referencing in your post, however, is relative sea level rise. It is happening in one part of the continent that you are studying.
What global warming can result in is global sea level rise.
Examples of relative sea level rise? Deepen a river to a canal on linking one sea to another and watch the canal fill with water. Or, in the case of Louisiana, put more and more sediment (and water) on a plate and watch the plate subside due to buoyancy of that plate and the slightly solid matter below it (asthenosphere).

Miami Beach flooding? Called erosion, subsidence due to building on top of unstable earth.
.
If you build on sea shores, swamps and alluvial areas you can expect them to sink and flood.
Human intervention causes this.

That was over 10000 years ago. That's not recent.
The above is sarcasm; however, it is the expected response of the warming acolytes who are ignorant of the paleoclimatic history of this planet and do not realize that 10000 years (much less 150 years [the period of "recorded temperature data"]) is not even a sliver of the Earth's history.

Thats all you needed to say.

South Pole making more ice...
That may make sense when you think about it, since 90% of people live above the equator. You would expect more melting in the north in this case.

How much do you think global temps have risen since humans have been keeping records for the last 150 years?

You would have to be a real idiot not to believe in manmade climate change.

I miss seeing the millions of ducks and geese at The Wheeler Wildlife Refuge like we use to see. The sky would be covered with them,now,not very much.They will never be back.
Pretty sure this was caused by DDT dumping in the river.
The pity is,there is no unpolitical research.All the studies are done with an agenda,by both sides,so for an average person to learn the real truth..that's impossible.
There is nothing wrong though,with us all trying to lower our impact where practical...just in case.
Waterfowl numbers are way up with most species being far beyond their environment's carrying capacity. I read recently where mallards are up about 50% over their carrying capacity and Blue Wing Teal, of all things, are like 600% over theirs (BWT are migrating later and later due to warmer falls....thus most states BWT seasons are missing the largest part of the migration....we used to never see BWT in Georgia during the regular duck season...now they are fairly common because they are migrating later and later).
If anyone doubts any of this take a look at conservation snow goose seasons....we are on the brink of a total disaster in snow goose populations because they are 1000's of times over their carrying capacity. It is so bad that spring hunting is allowed with no limits, no plugged shotguns and electronic callers....and we (hunters) are still not making a dent in the numbers....and the things are destroying grain fields wherever they are...it is only a matter of time before they die off by the millions due to some sort of disease but in the meantime they are reducing the amount of grain produced for years due to their destruction of grain fields. It is getting so bad that even the NWR system is considering spring hunting ON THE REFUGE!!!!
The ducks and geese are still here....they just aren't making it North Alabama because there is enough food and not enough ice in the midwest to keep them from coming that far south. People used to kill snow geese in South Georgia and Florida...now very few ever make it that far south because the cheseapeake bay area never gets cold enough AND there is plenty of grain left in the fields...

A few millimeters a year with a slight increase since the early 2000s

JBE and gang thinks its oil and gas industry. We know own otherwise.

The question is whether or not humans have a significant impact on the degree and haste with which it occurs.
That's the question climate scientists don't want answered. We will have to deal with a changing climate as climate always changes over time. The issue we have with climate scientists parallels the issue we have had with nutrition studies.

most of the ice is on greenland and the antarctic landmass
Since the ice in Antarctica is increasing, we must fear Greenland?
How much of Greenland ice has been melting? I'm scared.
Funny fact...for every inch the sea level rises, the circumference..or area..of the water surface increases requiring that much more melted ice to increase it another inch, etc etc.
