The melting of Thwaites is dominated by what’s happening underneath, where warmer water nibbles at the bottom, something called basal melting, said Peter Davis, an oceanographer at British An…
Scientists got their first up-close look at what’s eating away part of Antarctica’s Thwaites ice shelf, nicknamed the Doomsday Glacier because of its massive melt and sea rise potential, and it’s both good and bad news.
That fracturing “potentially accelerates the overall demise of that ice shelf,” said Paul Cutler, the Thwaites program director for the National Science Foundation who returned from the ice last week. “It’s eventual mode of failure may be through falling apart.” “Thwaites is a rapidly changing system, much more rapidly changing than when we started this work five years ago and even since we were in the field three years ago,” said Oregon State University ice researcher Erin Pettit, who wasn’t part of either study. “I am definitely expecting the rapid change to continue and accelerate over the next few years.”
Davis said the melting isn’t nearly the problem at Thwaites that glacier retreat is. The more the glacier breaks up or retreats, the more ice floats in water. When ice is on ground as part of the glacier it isn’t part of sea rise, but when it breaks off land and then goes onto water it adds to the overall water level by displacement, just as ice added to a glass of water raises water level.

Doomsday Glacier is melting slower than previously thought — but it's still in big troubleThwaites Glacier in West Antarctica, known as the Doomsday Glacier for the role its melt could play in global sea level rise, is melting more slowly than previously estimated, new research finds. But the glacier is still in trouble.
