Antarctic ice shelf could crack, raise seas by feet within decade, scientists warn

An Antarctic ice shelf could crack and disintegrate within the next decade, allowing a Florida-sized glacier to slide into the ocean and raising sea levels by feet, scientists warned Wednesday.

A dramatic chain reaction in the ice could occur by 2031, starting with the Thwaites Glacier, said Erin Pettit, a professor at Oregon State University who studies glacier and ice sheet dynamics.

New research Pettit presented to a meeting of the American Geophysical Union in New Orleans suggests the final collapse of the ice shelf may occur "within as little as 5 years" and mark the beginning of the end of the Thwaites Glacier.

Thwaites is the “widest glacier in the world” and has “doubled its outflow speed within the last 30 years,” said Ted Scambos, a senior research scientist at the Cooperative Institute for Research in Environmental Sciences and a contributor to the research.

All the water in the Thwaites Glacier would raise sea levels by 2 feet — but if its collapse triggers nearby glaciers to fall, the global sea level could rise by up to 10 feet, Scambos said.

A series of scientific studies of Thwaites in recent years has shown the enormous glacier is melting more quickly and in ways scientists never expected.

Very big and long cables attached to sky hooks or Dirigibles.

AND! It would create that 3 letter word “JOBS”.

This magnitude of sea level rise for this very reason has happened multiple times in the geological past the evidence is clearly in the stratagraphic record in many Paleo shorelines around the world. It is not clearly understood why catastrophic ice shelf release happens but it does and certainly will again. Adaptation is the only course of action mitigation is out of the question. If the data shows that this ice sheet is entering collapse there is nothing humans can do to stop it. Eustatic sea level changed is part of earth’s history. If it does go people will have a few years to move to higher ground as it takes time for the ice to flow down hill to enter the sea once it’s floating melting doesn’t matter it’s already displacing the water it will melt too.
