Dear Dr. Buchanan,

Thank you for submitting your manuscript entitled "The simulated climate of the Last Glacial Maximum and insights into the global carbon cycle” [Paper #cp-2016-73] to Climate of the Past. I have now received an assessment by two reviewers who found moderate issues that will need to be addressed before we can finally accept the paper. The first reviewer suggested an additional simulation to evaluate the attribution of changes in the carbon content and I agree with him that this would make the paper stronger. I also noticed that the paper misses a discussion about feedbacks associated with marine sediments (as e.g. discussed in Archer et al., Rev. Geophysics, 2000) which should be included in the revised version.
I suggest to change the title of the paper to "The simulated climate of the Last Glacial Maximum and insights into the global marine carbon cycle” since it focuses on the marine carbon cycle.

The feedback to your manuscript provided by the reviewer assessments is important and should be taken into account as you complete your revision. Please include a point-by-point reply to the reviewer comments, consider the reviewers’ concerns in the revision, and submit a marked-up manuscript version showing the changes made in your revision. I encourage you to submit a suitably revised version of your manuscript, if possible, by November 25, 2016.

Sincerely,
Arne Winguth

Dear Dr. Buchanan,

Thank you for addressing the comments raised by the referees in this revision; I am pleased to accept your manuscript, "The simulated climate of the Last Glacial Maximum and insights into the global carbon cycle" [Paper #cp-2016-73], for publication in Climate of the Past.

Please consider the following minor changes in the text:
Avoid the word "good" throughout the text (Pg. 7 L. 23, Pg. 8 L. 11, Pg. 9 L. 27, Pg. 12 L. 25, Pg. 15 L. 29, Pg. 16 L. 4)
Page 1 Line 15 add Pg C: "192 +/- 2 Pg C"
Page 10 Line 4. I recommend to replace elemental form of carbon in this section to either one of the following: carbon dioxide, dissolved inorganic carbon, or particulate organic carbon. Inventories can be given in Pg C.
Page 11 Line 1 delete "Clearly though"

Sincerely,
Arne Winguth
Editor
