The paper presents a comprehensive analysis of the diagnosed values of effective radiative forcing (ERF) for the CMIP6 models, and breaks down the contributions of this forcing from greenhouse gases, aerosols, and land-use.The use of ERF has continued to grow and it is now at least as widely-used, if not more so, than traditional metrics of forcing such as instantaneous forcing or stratospheric-adjusted forcing.It is an important paper for benchmarking the performance of CMIP6 models, and its findings will hopefully be used in upcoming assessment reports.That being said, there
