Warm Water Under The 'Doomsday Glacier' Threatens to Melt It Faster Than We Predicted - ScienceAlert

The first measurements ever performed below the icy tongue of Antarctica's Thwaites Glacier have now revealed a previously underestimated flow of warm water from the east. .

Right now, the Thwaites Glacier makes up about 10 percent of the current sea-level rise, but because warm and salty waters tend to converge underneath it, the ice shelf holds the potential to contribute much, much more as the planet warms

Ultimately, this means warm, salty waters are entering the cavity beneath the Thwaites Ice Shelf from both sides of its main pinning point in the north, possibly destabilizing the entire structure. 

That's equivalent to the total basal melt of the entire Thwaites Ice Shelf between 2010 and 2018, which indicates these warm inflows are likely impacting the entire system's melting pattern
