Warming sea water due to decreased salinity and infractions through the circumpolar current result in increased precipitation, which as you say results in an increase in volume of land ice - however this volume is accruing inland, while the coastal feet of glaciers and ice shelves continue to be undercut by said warmer water, which then allows their collapse, which allows increased flow, which allows retreat. Now - the worrying possibility which arises is that the combination of more on shore mass and less off/near shore buttressing will result in a net increase in flow, which will then contribute further to the positive feedback loop.
Honestly, nobody knows, our models are nowhere near granular enough. I prefer to err on the side of caution, and take a pessimistic view, but that’s just me.
All that you say is true, but:
