Antarctica's "Doomsday Glacier" update

(CNN)-- Ocean water is pushing miles beneath Antarctica’s “Doomsday Glacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space to perform an X-ray of the crucial glacier.

As the salty, relatively warm ocean water meets the ice, it’s causing “vigorous melting” underneath the glacier and could mean global sea level rise projections are being underestimated, according to the study published Monday in the Proceedings of the National Academy of Sciences.

The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida. It’s also Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice.

Thwaites, which already contributes 4% to global sea level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world’s coastal communities.

I'm 59 in Florida, will I be shuffled off this mortal coilby the time it melts?

I share those thoughts. We just might miss all the real action!
