Dear authors,
Thank you very much for the revised version that you submitted. I sent the new version to the two reviewers who both agree that you have seriously improved the initial version of your manuscript and they both propose publication. However, they also both require minor revisions of your manuscript and I am following their request. I invite you therefore to revise once more your manuscript before final acceptance, taking into account the last comments.
Looking forward to reading your revised version

Dear authors,
Thank you for following the second round of comments and reviews. Your revised manuscript seems ready for publication. I just have a final request.
In one of your replies to the second main point raised by reviewer#2 you replied:" Your suggestion about using the modern shell is really good to support our argumentation. In fact, we do use a modern Tridacna, collected in Xisha Islands with an accurate daily time-scale, to analyze the growth rate change under daily increments by using laser scanning confocal microscope. The result shows it is true that Tridacna from Xisha Islands grows fast in warm while relative slow in cold temperature. However, this paper is accepted by PNAS and will be published soon. We apologize here that we cannot cite right now.".
However, if the manuscript your refer to is accepted by PNAS, therefore you have all the elements to cite it without any problem, there is a DOI to protect it. Therefore, please do so in a final correction.
Thank you for choosing Climate of the Past to publish your interesting results.
All the very best
