Part of situation: Thwaites Glacier melting and seismic research (8 clusters)

Thwaites Glacier melting faster than previously projected

Thwaites Glacier sea level rise West Antarctica glaciology climate change

New research indicates that the Thwaites Glacier in West Antarctica, often referred to as the ‘Doomsday Glacier’, is melting more aggressively than previous models suggested. A study published in Nature Communications by researchers from UC Irvine and NASA Jet Propulsion Laboratory reveals that the glacier could contribute up to 30 mm to global sea level rise by 2100, a figure approximately twice as large as earlier projections.

The discrepancy arises from how models account for the grounding zone—the area where ice transitions from resting on the seabed to floating. While older models treated this as a sharp line, new data shows a broad zone, several kilometers wide, where warm seawater penetrates deep beneath the ice shelf during tidal cycles, accelerating melting from below.

Additionally, international researchers from ETH Zurich and Vrije Universiteit Brussel found that traditional climate models often underestimate ice loss by using monthly averages. By incorporating daily meteorological data, such as extreme heatwaves and sudden temperature shifts, the Global Glacier Evolution Model (GloGEM) provides more accurate simulations of glacier behavior.

Currently, the Thwaites Glacier contributes about 4 percent to global sea level rise. Scientists warn there is a 60 percent chance the glacier will disconnect from the Mouginot Ridge, an underwater feature currently stabilizing it, by the end of the century.
