> "Thwaites is really holding on today by its fingernails, and we should expect to see big changes over small timescales in the future -- even from one year to the next -- once the glacier retreats beyond a shallow ridge in its bed," Robert Larter, a marine geophysicist and one of the study's co-authors from the British Antarctic Survey, said in the release.

The actual number is 25 inches, and most consensus suggests collapse over centuries.

There is some concern that a bracing portion of the glacier may collapse soon, which would take Thwaites from 4 to 6% of contribution to sea level rise.
