I honestly don't know anything past those facts, but if the sea level actually fell, all that water had to go somewhere, either as vapor, liquid, or as solid ice. And it's a hell of a lot of water we are talking about here.
1/3 of an inch of sea rise is enough to swamp all the dry land in Bangla Desh. It's enough to cover the Marshall Islands and most of Guam.
The Earth hasn't lost any of it's water. It's all still here someplace- it's just not in its usual places in its usual amounts.
All the water this planet has was created almost instantaneously when the seas formed, and Earth became a water world, dry no more forever. Earth never creates water, nor loses it- gravity takes care of that. Our planet's water constantly cycles in an endless closed loop between its 3 forms; vapor, liquid, and solid. But none is equally present all the time in one form only. Ice evaporates directly into vapor without ever becoming liquid first when its cold enough.
Because of this inequality, Earth has gone through long periods of ice covering the land, long periods of vapor turning into perpetual rain/snow storms, and long periods of lasting drought over most of the land with extremely lush small belts that lie under the jet stream paths where the vapor condenses into rain.
Historically, any of these drastic shifts happen very quickly after some prolonged unpredictable shiftiness. And then, once a prevailing change happens, it changes very slowly, with short dramatic intervals that keep Earth's climate stabilized over all the planet.
The geologic evidence is abundant on this. What we don't know is what causes the shifts to begin. The only thing we have learned is there are many causes, but how they combine and what happens after a combination is still something we are learning. It's never one thing, it is always a combination of factors. That's very well known, but there are lots of combinations we have not discovered yet.
If if the water left the sea, it's doing something we aren't prepared for, somewhere. That something is big, whatever it is, because it's ALWAYS big. Because Earth is a water planet.
We can't be prepared for them all until we know what they are. Until then, all we can do is be cautious and aware of what we know for a fact, and that's all we can do something about.
But I'm not at all sure the OP report is accurate or even true, so I asked the question. If it is true, someone should have an answer, at least in part.
And twice, I got nothing. That tends to make me think the quoted report was closer to BS than true.

....There was no two year dip....Sea level increased by 6.4 mm. in the last two years...
