" 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 On Tuesday, November 21, 2017 at 7:01:59 PM UTC-5, Andrew Lockley wrote: > > > https://grist.org/article/antarctica-doomsday-glaciers-could-flood-coastal-cities/ > > I very rarely share something that's aimed at the lay reader, or off > topic.
