If sea levels are truly falling, can you provide evidence to that claim?
Also the Florida keys have been under a coastal flood advisory for a good portion of the past month, due to higher than predicted tides. This kind of event certainly does not indicate sea levels are falling.

My first evidence as I said already is take yourself to the shore and see where the water comes to. In my case where I've lived for over 50 years there is no decernable change.
Next go to NOAA site and look up sea levels. They give a bunch of readings spanning up to approx 100 years. They concede that their readings do not take account of land movement. So in fact they mean nothing.
100 years is not a long time when talking about sea levels.
For a better picture you need to step back a bit and look at 1000's of years.
When you do that you find that from about 22000 years ago to about 6000 years ago sea levels went up by 140m
Please note there were no carbon emissions by people during that time. VW cars had not been invented yet.
From 6000 years ago to about 1500 years ago levels continued to rise but at slower rate.
From 1500 years ago till now the level has fallen by about 1m.
The highest it ever was was 1500 years ago.

In the period of 1500 years the level is sometimes going up and sometimes is going down.
The reasons given for the ups and downs are many and varied but in truth nobody really fully understands it.
If your going to take the last 100 years and see a miniscule upward trend and then say that proves something I say your wrong. Looking at 1500 years shows a huge reduction in levels.

Doubt any of us will witness this. At a few millimeters a year, or a few more added for acceleration, it is going to take a while.

As you say is not the same as providing actual evidence to your claim.
I really think you may have missed the point of my discussion about Florida's seasonal high water in early fall that has prompted coastal flood advisories every fall since at least 2012.
If anything that might be an indication that there might be some truth in the claim that sea levels are rising.

Abstract
Nile gauge records of variations in Nile floods from the 9th century to the 15th century AD reveal pronounced episodes of low Nile and high Nile flood discharge. Historical data reveal that this period was also characterized by the worst known famines on record. Exploratory comparisons of variations in Nile flood discharge with high-resolution data on sea surface temperature of the North Atlantic climate from three case studies suggest that rainfall at the source of the Nile was influenced by the North Atlantic Oscillation. However, there are apparently flip-flop reversals from periods when variations in Nile flood discharge are positively related to North Atlantic warming to periods where the opposite takes place. The key transitions occur atAD 900, 1010, 1070, 1180, 1350 and 1400. The putative flip-flop junctures, which require further confirmation, appear to be quite rapid and some seem to have had dramatic effects on Nile flood discharge, especially if they recurred at short intervals, characteristic of the period from the 9th to the 14th century, coincident with the so-called Medieval Warm Period. The transition from one state to the other was characterized by incidents of low, high or a succession of both low and high extreme floods. The cluster of extreme floods was detrimental causing famines and economic disasters that are unmatched over the last 2000 years.

But this is a complicated issue. We don't know what will happen. We could get some rapid ice melt and a few feet. Or we could get a few inches or centimeters and that might be enough to cause some bigger more devastating storm surges.

I do believe there are sock puppets whose goal is to make it appear that being in denial of the science behind climate change is more popular than it really is, manufacturing a consensus.
