The same thing happens when the ice cubes in you drink melt, the level stays the same!
Perhaps a few percent, but not the same as the entire volume of ice.“The common misconception that floating ice won’t increase sea level when it melts occurs because the difference in density between fresh water and salt water is not taken into consideration. Archimedes’ Principle states that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid it displaces. However, Noerdlinger notes that because freshwater is not as dense as saltwater, freshwater actually has greater volume than an equivalent weight of saltwater. Thus, when freshwater ice melts in the ocean, it contributes a greater volume of melt water than it originally displaced.”

I agree with the gist of what the paper says. They correctly model the possible tipping point using a hysteresis curve. This however is a perfectly natural cyclical event. Temperature does play a role, but not as much as ice mass changes. This event has almost certainly started already and accelerating.
Does the water height in your glass increase in height when the ice cubes melt?
The effect is very insignificant.“The common misconception that floating ice won’t increase sea level when it melts occurs because the difference in density between fresh water and salt water is not taken into consideration.

Assuming they are correct, if I take a 361 gigaton block of ice, and put it in the ocean, it increases the ocean height by 1 mm. When that block of ice melts, it increases the ocean height an additional 0.026 mm. This is based on an extreme variance to what sea water really is. They uses an extreme percentage of salt in the water to show there was a effect. The problem is, with the comparatively low salt concentration in the oceans to what they used, where would be no observable effect has the used the concentrations of salt found in the oceans. They used only about three times as much saltwater as ice, and the saltwater density was 1.197 gm/ml. Sea water density is only 1.0273 gm/ml.

At what density do you drink your salt water?
Actually you cited article supported the idea that the change in sea level would be minimal,
It does stay the same with fresh water, and the difference between fresh water and sea water is minimal, like your cite says 2.6%.
Not at all, post number 4 was a simple observation that the level in a drinking glass does not change when the ice melts.
The ice would not stick out 6 inches if it were floating!
How so?
I tested it too with a saturated mix. I had a considerable increase in level, which I did expect. Only problem, being saturated at 1.1972 gm/mL, I wondered what thermal expansion is for saltwater that concentrated. I couldn't find the data in a short time, not sure where to look. Consider that as soon as you put that much ice in a small volume of water, the water cools considerable. When you melt it and its at room temperature, how much is due to thermal expansion? I doubt it was significant, but I cannot say that with any certainty.
