Antarctic ice shelf crack is moving at record speeds, poised to cleave off massive iceberg any minute

A crack spreading inexorably across the Larsen C Ice Shelf in northwest Antarctica has surged forward at record rates, bringing the ice shelf closer to cleaving off an iceberg roughly the size of Delaware.

If this occurs, it would be one of the largest icebergs ever observed and could leave the ice shelf behind it in a precarious state, more vulnerable to melting from both relatively mild ocean waters encroaching on the ice from underneath, as well as increasing air temperatures melting ice from above.
