We settled on Wagner and Weitzman because it is well known and also because they were kind enough to provide us with their data and code. It is indeed true that other probability curves might paint a more optimistic picture. However, the differences are so large that I would be surprised if it would change the conclusion of our paper.
We looked at the complete IPCC reports, because we wanted to understand the overall focus of policy relevant research. But it is indeed true that the research gap differs between the working groups and the research gap is larger when it comes to the impact focused reports.
