Please see uploaded comments. I hope they help improve the manuscript.

My apologies to the editor and authors that this was a few days late.

I read with attention and interest the article by Bonsoms et al "Projected climate change will double the late Holocene maximum...", and found it well written and organized, full of results relevant not only to cryosphere/paleoclimate specialists, but also to those dealing with the impacts of climate warming on the Arctic ecosystem in general.

My opinion is positive and I have not found any formal or substantial weaknesses.

It is a modelling paper, and therefore it is not easy to read for those who are not into this subject. The data are many, the text constantly refers to acronyms, and rightly some methodological aspects are not discussed in depth. I believe that this is the only way to write papers of this type, and in any case the results in terms of glacial extension and paleoclimate are clearly expressed and usable in other scientific contexts. The use of chronological data (CRE ages) relating to glacial landforms is a point of merit, which makes the modeling even more robust.

The results are discussed in light of other data available for the same area and for the Arctic region in general, and the conclusions are concise. The authors may consider adding a short list of the main results at the beginning, to help the reader to recap before reading the final comments.

Best wishes
