Not the point. It's merely used as an indicator of climate instability in a region with a lot of above-sea-level ice that has, for the last few hundred millenia, held that ice in stasis. If the sea-level ice shelves that took many centuries to form suddenly un-form in a short period, it shows rapid warming of the sea in the region.
