Dear Dr Ladant

your manuscript submitted to Climate of the Past has been evaluated by two reviewers. Both of them are enthusiastic about your contribution, and found your results particularly relevant in the context of the Cretaceous climate and oceanic circulation. From their reviews and from my own reading, I think that the point raised by the first reviewer asking you to add a strong and well documented discussion about the sensitivity of the climate and oceanic patterns to the CO2 level is important. From your answer to the reviewer, I realize that this can be done easily. The point raised by the second reviewer about the length of the paper can be solved, as you suggested, by improving the structure of the paper, adding clear subsections. I appreciate also your efforts in shortening the article as far as possible.
Overall, I think that you already have done a great job in answering the reviewers, and I'm sure that you can improve the ms. I would be happy to receive the revised version, that I will check before definitive acceptance.

Dear author,

Having checked you revised version, I'm glad to accept formally your contribution for publication in Climate of the Past.

Best regards.
