A glacier in Antarctica the size of Florida that could dramatically raise global sea levels is disintegrating faster than previously predicted, according to a study published Monday in the journal Nature Geoscience.
A glacier in Antarctica the size of Florida that could dramatically raise global sea levels is disintegrating faster than previously predicted, according to a study published Monday in the journalA group of international researchers mapped the historical footprint of western Antarctica’s Thwaites Glacier — nicknamed the “doomsday glacier” because of the massive impact its collapse due to warmer temperatures would have.
“Thwaites is really holding on today by its fingernails, and we should expect to see big changes over small time scales in the future — even from one year to the next — once the glacier retreats beyond a shallow ridge in its bed,” British Antarctic Survey’s Robert Larter, a co-author of the study, said in aThe reverberations of that melting could be huge, according to the scientists involved in the research.
The research vessel the Nathaniel B. Palmer working along the edge of the Thwaites Eastern Ice Shelf in Antarctica in 2019. The Thwaites Glacier is one of the widest on Earth, but it’s just a small piece of the West Antarctic Ice Sheet, which contains enough ice to raise sea level by up to 16 feet if it were to melt, according to NASA.
Thwaites is grounded in the ocean floor, rather than land, making it especially prone to melting due to warming waters. In 2020, scientists found that warm water

Florida-sized 'doomsday glacier' in Antarctica is melting faster than thought, study saysAntarctica’s “doomsday glacier” — given the nickname because of its high risk of collapse and threat to global sea levels + the economy — has the potential to retreat within five years. The glacier is capable of pushing up sea levels by several feet.
