Review of the revised manuscript ``Improving the representation of anthropogenic CO2 emissions in climate models: a new parameterization for the Community Earth System Model (CESM)'' by Andr\'{e}s Navarro, Ra\'{u}l Moreno, and Francisco J. Tapiador, submitted to the Journal Earth System Dynamics, European Geosciences Union (EGU).

---------------------------------------

I would like to express my gratitude to the Authors for addressing the first round of comments from the Reviewers. The manuscript would be ready for publication following the minor changes described below.

1. Page 2, Line 10: Change ``Human activity was a major driver of change in the Earth System in the recent past (Alter et al., 2017; Barnett et al., 2008; Crutzen, 2002), and it now dominates the natural system (Ruth, et al. 2011).''

``Human activity has become a major driver of change in the Earth System, especially over the past several decades (Alter et al., 2017; Barnett et al., 2008; Crutzen, 2002), and it now dominates the natural system in many different ways (Motesharrei et al., 2016; Ruth, et al. 2011).''

4. Page 6, Line 6: Change ``simulating the dynamics of the population'' to ``simulating the observed population''.

5. Page 7, Section 2.3: I think it would be helpful to refer to the newly released CESM2, and mention the possibility of coupling POPEM to CESM2 in the future. See, for example:

Joel, L. (2018), New version of popular climate model released, Eos, 99, https://doi.org/10.1029/2018EO101489. Published on 22 June 2018.

6. Page 15, Line 20: Change ``bidirectional feedback'' to ``bidirectional feedbacks''.

7. Page 15, Line 23: Change ``the counterintuitive feedback that is missing'' to ``the important feedbacks that are missing''.

Short summary

Earth system models provide simplified accounts of human–Earth interactions. Most current models treat CO₂ emissions as a homogeneously distributed forcing. However, this paper presents a new parameterization, POPEM (POpulation Parameterization for Earth Models), that computes anthropogenic CO₂ emissions at a grid point scale. A major advantage of this approach is the increased capacity to understand the potential effects of localized pollutant emissions on long-term global climate statistics.
