Good news!

$1:

As warm water melts the ice between the glacier's surface and the bedrock, the glacier retreats and the ice on top is more likely to break off.

More land!

Err, actually that ice would lead to 3 feet of sea rise, meaning 1,300 square miles of coastline is lost forever. And the land under the glacier would still remain unusable tundra, it would just lack that giant ice cube stuck to it today

How do you know that?
Forever is a long time. Are you a magically divine prophet???

I know what you're getting at. Kind of like lost cost line when the Ice age ended. More polar ice = less ocean water = more land mass / cost line

Not arguing per say just wondering why it can not be used for something?

"Records" in Antarctica cover a remarkably short time period and the records of water temps under any ice sheet down there only go back at best two or three decades.

This one's from 2014 and originates at the University of texas:

AUSTIN, Texas — Thwaites Glacier, the large, rapidly changing outlet of the West Antarctic Ice Sheet, is not only being eroded by the ocean, it’s being melted from below by geothermal heat, researchers at the Institute for Geophysics at The University of Texas at Austin (UTIG) report in the current edition of the Proceedings of the National Academy of Sciences.

Antarctica would still be incredibly cold for almost the entire year, and never receives a lot of light. So if the glaciers were to completely melt away they would just reveal scrub land. Like far northern Canada. It would take eons for the soil to change from rocky to something you can farm on as well.

Basically Antarctica doesn't have to warm up a lot for the glaciers to fall apart, and it still leaves the land as a frozen wasteland.
