Editorial comments:
I agree with the reviewers that there is no novelty in this paper. The response by the author is that this is a synthesis from a lecture given at the EGU general assembly. My impression is that this paper would be valuable to a wide community of researchers in climate change. I suggest a note in the manuscript saying that this paper is the synthesis from the Alexander von Humboldt’s medal lecture given by the first author (FG) at the 2018 EGU general assembly.

In some instances, the author responses are directed only at the reviewers. The authors should also include the responses in the main text so that the benefit of review could reach a wider audience. For instance, the response to the comment “why only 10 models are used in the analysis” should be also discussed in the main text. There are 8 new figures in response to reviewer #1. These figures should be included in either the supplemental material or in the main text. The x- and y-axis labels are missing for these new figures. I ask the authors to make sure all the responses to the reviewers’ comments are also discussed in the paper.
