A melting glacier in Antarctica has experts worried.
The Thwaites Glacier, nicknamed the "doomsday glacier," might raise global sea level by many feet if it collapsed.
Scientists have concerned about the Florida-sized icecap's disappearance for years.
Since 1973, scientists have feared Thwaites.

Doomsday glacier is wider than Florida.
NASA says melting would raise sea levels 16 feet.
The glacier's "fast-flowing trunk has sped up, thinned, and broadened" since 2011, according to satellite studies.
This frail structure has worried scientists for decades, earning it the nickname "West Antarctica's weak underbelly."
