Dear authors,

First, I would like to apologize for the delay.

Your contribution has been seen by two reviewers, whose reports are both positive. They emphasized the high quality of your method and the high interest of your results (CO2 levels during the late Eocene). Based on those reports and on my own reading, I think that your paper is an important contribution, clearly deserving publication in Clim. Past.

I strongly suggest that you submit a revised version of your ms, accounting for all the reviewers comments, as you did in your 'answer to rev' document. As both reviewers, I also think that the discussion related to the relative timing of the CO2 and temperature changes must be removed, given the time resolution of your study.

Best regards

Dear authors,

Thanks for submitting a revised version of your manuscript. I think you answered all the concerns raised by the reviewers. I'm glad to accept your contribution for publication in Clim. Past.

Best regards
