One estimate predicted that the total loss of Thwaites could cause average global sea levels to surge by more than 2 feet and could cause sea levels to rise even more in some parts of the U.S.
They found that seawater flows in and away from the glacier with the tides, mixing with freshwater, but some of that warm ocean water also travels deep beneath the ice formation, going "through natural conduits" or collecting "in cavities" and becoming trapped.
"The water is then squeezed enough to jack up a column of more than half a mile of ice."
"This work will help people adapt to changing ocean levels, along with focusing on reducing carbon emissions to prevent the worst-case scenario," Dow says.
