Accurately representing the complex interactions between ice sheet and atmosphere remains a challenge for projections of future sea-level rise. In this study, the authors demonstrate the importance of capturing the two-way feedback between the systems. The study shows that, in model simulations that include feedback, the Greenland ice sheet loses significantly more mass than in simulations without feedback.

To study Greenland ice sheet–atmosphere interactions, we coupled an ice sheet model to a regional climate model and performed simulations of differing coupling complexity over 1000 years under a high-warming climate scenario. They reveal that at first melt at the ice sheet margin is reduced by changing wind patterns. But over time, as the ice sheet melts and its surface lowers, precipitation patterns and cloudiness also change and amplify ice mass loss over the entire ice sheet.
