The authors are to be commended for their clear and cogent report on a very large body of work. The conclusions are well presented and state clearly the reasons for the large range in projections. The discussion points to key areas of ongoing development. On my view, the authors have responded reasonably and well to the issues raised by the two reviewers (who are also to be thanked for their clear and helpful reviews).

If it is possible for the figures to be presented using more universally accessible colour schemes, that would be a useful improvement to make. This may be hard to do in cases like Figures 1 and 4, where so many models are presented together without an explicit ordering (Figure 5, in contrast , has an explicit ordering which helps). But in figures like 8, 10, and 11, different intensities for the different categories could add another visual cue to help the reader whose colour perception is different from most.
