More on why sea level is likely to rise above standard projections within the century:

Doomsday on Ice

Rapid collapse of Antarctic glaciers could flood coastal cities by the end of this century.


By Eric Holthaus on Nov 21, 2017

"The only place in the world where you can see ice-cliff instability in action today is at Jakobshavn glacier in Greenland, one of the fastest-collapsing glaciers in the world. DeConto says that to construct their model, they took the collapse rate of Jakobshavn, cut it in half to be extra conservative, then applied it to Thwaites and Pine Island."

Pine Island Glacier is already shifting to a new regime. A huge iceberg just calved off it..... Once the ice calves behind the grounding line the whole glacier will collapse and rapidly retreat just like Jacobhavn Glacier in Greenland....and then collapse will eat its way into the interior of the West Antarctic Sheet, causing ice drawdown from the entire ice sheet.
