Short summary
This work examines how interactions between the ice sheet and the Earth’s evolving surface affect the future of Thwaites Glacier in Antarctica. We find that small features in the bedrock play a major role in these interactions which can delay the glacier’s retreat by decades or even centuries. This can significantly reduce sea-level rise projections. Our study highlights resolution requirements for similar ice–earth models and the importance of bedrock mapping efforts in Antarctica.
