Dear Felicity and co-authors,

Thank you very much for your considered and careful responses to the reviewers' comments.

I suspect that the modifications you propose to the manuscript will address the key concerns; however, I would like to send this out for a second round of reviews, given a few of the reviewer comments around the modelling framework and overall structure.

Best regards,
Felicity McCormack

Dear Felicity and co-authors,

I have received comments form both referees, who are satisfied with your responses and the changes made to the manuscript. They have a few comments and suggestions in the attached reports.

I look forward to receiving your revised text.

Best regards,
Felicity McCormack

Dear Felicity and co-authors,

Thanks very much for your response to the comments and modifications to the manuscript.

We would be very happy to accept your manuscript for publication in the Cryosphere, subject to the following very minor corrections:
- Abstract Line 1 (and elsewhere throughout manuscript): Greenland ice sheet → Greenland Ice Sheet
- Line 67 (and elsewhere?): “in light of its current stability”. Recommend to avoid using the word stability unless referring to specific, mathematical stability. Perhaps use “persistent grounding line” or “limited recent changes” instead
- Line 437: delete repeated “response”

Thanks again for choosing to submit to the Cryosphere.

Best regards,
Felicity McCormack
