Just how fast would the Pine Island and Thwaite glaciers  have to advance 
to reify Grist's fear that :

" Minute-by-minute, huge skyscraper-sized shards of ice cliffs would 
crumble into the sea, " ?

As huge skyscrapers tend to be tens of meters wide,  the article  implies 
that the rate of Antarctic glacial  advance is about to accelerate  to  the 
 un-glacial  pace  of   > 10  x  60 x 24 =   ~ 1.4  kilometers a day or 
more.

Some explicit dimensional analysis  would seem  in order if  the  authors 
expect to change the minds of those who have seen far steeper  bergschrunds 
 ( Like the  Nanga Parbat massif's Raikot glacier ) clanking along  at far 
lower speeds and higher temperatures
