“So their volume is already accounted for in total volume of water of the oceans. Just like a glass full of ice-cubes and water doesn’t overflow when it melts. “
Yup. 90% of the Ross ice shelf is already under water.
Their ‘theory’ is: if it melts then the land ice will flood into the ocean.
The problem with that theory is...actual science: The Antarctic land ice, because of its weight, sits in a bowl. Ice doesn’t flow uphill.

Their theory also depends on the ice never getting replenished on the continent. Just like how rain and snow fall on mountains, only to collect into rivers which flow down hill to the oceans, ice does the same thing in glaciers. All ice that breaks off Antarctica is replaced by new snow on the continent.
