According to the evaluation of the three reviewers, your manuscript needs major revisions. I encourage the authors to submit a revised manuscript showing track changes and taking into account all the review comments. The revised manuscript will be sent to the original Reviewers for re-evaluation.

Dear Authors,

Thanks for having submitted a revised manuscript and point-to-point reply to the review comments. Only Reviewer 1 has read and commented on the revised manuscript. You will see that he is not satisfied with the revised manuscript nor with your reply. He thinks that your manuscript still suffers from a lack of clarity and conciseness and your replies to some of his previous comments are unsatisfactory or even contradictory. I strongly recommend you to revisit his comments and to make necessary clarifications and improvements in your manuscript before a final version can be accepted in Climate of the Past. If you submit a revised version, please submit one showing track changes together with a reply to the second report of Reviewer 1.

Sincerely,

Qiuzhen Yin
