Part of situation: Thwaites Glacier melting and seismic research (9 clusters)

Thwaites Glacier melting faster than previously estimated

Thwaites Glacier sea level rise Antarctica climate change glaciology

New research indicates that the Thwaites Glacier in West Antarctica, often called the ‘Doomsday Glacier,’ is melting more rapidly than previously estimated. Glaciologists from NASA and the University of California have developed a more sophisticated ice sheet model that accounts for complex physical processes occurring beneath the glacier. This new model suggests that the glacier's impact on global sea level rise could be double previous projections.

Key findings reveal that the glacier's grounding line is actually a wide grounding zone where tidal pumping causes seawater to flow in and out, eroding the ice from below. This process contributes to approximately 4% of current global sea level rise. If the Thwaites Glacier were to collapse entirely, it could raise global sea levels by approximately 65 centimeters. Furthermore, because the glacier acts as a stabilizer for the broader Antarctic ice sheet, its loss could potentially trigger a total sea level rise of up to 3 meters.

Additionally, studies from the British Antarctic Survey suggest that the glacier is destined to continue losing ice for at least the next 150 years, even if ocean temperatures were to cool significantly. The accelerated melting poses a severe threat to coastal communities worldwide, from Miami to Manila.
