Summary
Beyond 2100, the Greenland Ice Sheet enters a new regime. We explored scenarios over 200 years, showing that even if warming stabilizes, the 'melt-elevation feedback' can trigger irreversible mass loss. This work emphasizes that current 2100 targets might hide the long-term commitment of ice sheet retreat.
Key Takeaway
"Atmospheric warming thresholds are likely to be exceeded long-term, leading to a sustained and accelerating contribution to sea-level rise."
