Exactly when that will happen is the big unknown.

After all the global climate has warmed less than one degree C overall. Or is this just a model of what might happen?
My quesation was this: The climate has warmed in the past. From ~1880 to ~1940. Did these Antarctic ice shelves start to collapse back then? Or at any time in the past?
Yes, you read that correctly: "at least 1 mm of sea-level rise over a few decades." Batten the hatches, we're all gonna drown!"Loss of buttressing offsetting half of the tendency for ice‐stream/ice‐shelf spreading for an ice stream similar to Pine Island Glacier, West Antarctica is modeled to contribute at least 1 mm of sea‐level rise over a few decades." https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2004GL022024
90 % of the sea ice shelves breaks off yearly never a boost to sea level. Think on it put some ice in a glass with some water mark the level. When the ice melts does the water in the glass rise, does it over flow. Displacement, it stays the same. Give me something tangible to believe in on man made climate change, other than we need a tax administered by the UN who backs this climate change hocus pocus
A response to Chem721. It is important to distinguish between glacial ice and polar ice shelves as Mogoso pointed out. The back and forth growth and retreat of glaciers is well known. My question was about the polar ice caps, not glaciers.
"To capture and permanently remove and bury just one part-per-million of oxidized carbon (at the source or directly from the air) means the safe burial of 7.8 Gt, or 7,800 million metric tons. At today's burial rates that ONE ppm would take about 200 years."
Totally impossible.
There is no imminent danger of island countries or shorelines being inundated that are not otherwise subsiding.
Do the math.
