I look forward to seeing the revised manuscript, with particular attention to the following points:
1) Clarification and simplification of the abstract
2) Clarify hypothesis 1
3) Discussion of the possible role of calcite or other reactive trace phases on weathering fluxes.
4) With regard to point 4 in RC 2, please describe the relationship between mean annual precipitation and temperature (used in the model) and the range in these values (which may actually be the more relevant drivers of weathering)
5) Briefly explain how PROFILE works
6) Improve presentation of Figure 5
Please explain your decisions with regard to all major comments of the reviewers.

Thank you for attending to comments from the reviewers.
