Dear Dr. Markus Czymzik,

Thank you for submitting your work to Climate of the Past, and for your responses to referees’ comments. Although both referees indicated the importance of chronology studies, they both raised some fundamental issues that would require your considerations through a major revision. The comments from Dr. Simon are particularly detailed. I am not intending to repeat their comments; all are clear and constructive. If you agree to revise the manuscript following these comments, I’d be happy to send a revised version of your revised manuscript to them for a second-round review.

with the best wishes
