What occurs after the "Doomsday Glacier" melts away?

The "doomsday" symbolised by the name "Doomsday Glacier," according to many climate change activists, may be approaching soon.

What we now know: New research examined ridges on the seafloor. These rib-like formations demonstrate how the glacier was pushed for aeons by the sea.

This is distinct from earlier information gleaned from satellite images of the glacier as it approaches a full (or nearly full) collapse into the ocean.

The consequences of this glacier's impending collapse are severe. 4% of climate change is caused, according to the International Thwaites Glacier Collaboration.

Thwaites has been the source of sea level rise so far, and a sudden catastrophic collapse would raise sea levels by 25 inches. 

Mississippi's and Louisiana's southern regions would be destroyed. Although Hudson Yards may flood, Manhattan would just be sprayed. Venice Beach would be the only part of Los Angeles spared.
