'Doomsday glacier' close to collapse - could raise sea level

Can quickly withdraw
The research shows that Thwaites can retreat quickly, once the glacier breaks free from a seafloor ridge that helps hold it in place.
“Thwaites is really hanging on and we should expect to see big changes in the future – even from one year to the next,” says Robert Larter , one of the study’s co-authors.
Melts from below
Scientists have worried about the glacier for decades because warm ocean currents can melt the glacier from below, which research from 2020 shows is indeed happening. Thwaites, located in West Antarctica, is one of the widest on Earth and is larger than the state of Florida.
The latest research has mapped a huge area and shows that the glacier may be retreating at a much faster rate than previously thought.
The lead author of the study, Alastair Graham , states that the research “truly was a once-in-a-lifetime mission”.
Wants to return to Antarctica
The researchers want to return to Antarctica soon to collect samples from the seabed so they can continue to determine when the previous rapid retreats of the glacier occurred. It will then help to predict future changes to the “doomsday glacier”.
