Dear Authors,

Thanks for addressing most of the reviewers' comments in the revision. However, one reviewer still has comments, regarding the uncertainty of representing cloud forcing in GCMs specifically, and more general the limitation of models in the climate prediction and geoengineering. some of these limitations need to be made clearer in the abstract, introduction and conclusion sections.

Best regards,
Xiaohong Liu

Dear Authors,

Thanks for making revision of your manuscript in response to the reviewer's comments. There is one more change that is needed:

Line 201: "From these findings, we can conclude that results obtained over the past 20 years of study have not been overturned". Please change "20 years of study" to "two generations of models" to be consistent with changes in other places of text.
