Scientists warn Antarctica's "doomsday glacier," termed for its high risk of collapse and danger to global sea level,
might swiftly recede in the next years, heightening fears about catastrophic sea level rise.
As the world warms, the Thwaites Glacier's underwater foundation is dissolving.
In a research published Monday in Nature Geoscience, scientists traced the glacier's history retreat to predict its future.
In the previous two centuries, the glacier base detached from the seafloor and receded 1.3 miles (2.1 km) every year.
This rapid collapse may have happened as recently as the mid-20th century, research author Alastair Graham said.
