“If the land ice & semi-floating ice above the Byrd Subglacial Basin start to break & shear, then we can speak of a self-reinforcing effect due to the sea level rise itself, or better due to the lifting & destabilization of all ice shelves, glaciers & high land ice.”

“This would then mean that we are reaching the penultimate phase, which is comparable to the 20 to 25 meters we saw during the last climatological optima in the middle Pliocene & in the middle Miocene, when temperatures in the Arctic Ocean & Southern Ocean were similar to today.”
