Dear authors,

thank you for your detailed response to the reviewer comments, which overall meet the points of criticism very well. Accordingly, I would ask you to carry out the final changes in the manuscript and upload it after these revisions preferably also in a version where all your changes are clearly marked.

In addition to your planned changes indicated in your reply, I would like to stress the following issues to be implemented in your revisions:

- The work by Goelzer et al., 2015 appears to be most important for your paper and it is published in CPD and therefore citable (it has a doi and will continue to be available on the web). Please include it in your revised version.

- reviewer #2 makes an important point on alternative processes that could lead to millennial-scale cooling of the northern hemisphere. Please elaborate shortly on those in your introduction.

- please state in your text that the data uncertainties have not been included in your RSME (see also annotated pdf attached to this editor's reply)

- you may want to cite Goelzer et al. (CPD 2015) and DeConto and Pollard (Nature, 2016) on the issue of WAIS collapse in models

- a few minor language issues have been annotated in the file attached.

Looking forward to the revised version of this interesting manuscript

Regards Hubertus Fischer
