The article by Darrell Kaufman and Valérie Masson-Delmotte provides a useful Opinion piece on the inclusion of paleoscience in the upcoming IPCC AR7.

This article presents an interesting link between climate and weather patterns, and in particular how this may have impacted recent human history.

This paper is an excellent example of how sophisticated climate reconstructions can be made on the basis of historical documentary data. The authors have not only succeeded in analysing the rich historical descriptions in a very valuable way, they have also applied various statistical approaches very skillfully in a remarkably interdisciplinary approach. The article stands out for its deep understanding of historical sources, drought processes, and various social processes.

The Atlantic Meridional Overturning Circulation (AMOC) is at its weakest of the last millennium and is projected to further weaken over the coming decades, with the risk of a collapse over the coming century non negligible. The geologic record provides examples of rapid and large AMOC variations, with phases of AMOC weakening, preceding an AMOC shutdown. One key question is whether CO2-driven AMOC weakening is reversible, or whether it represents a tipping point, which might lead to an AMOC collapse. The study by Willeit et al. offers a new diagnostic that is simple to implement and allows for comparing AMOC stability between different models, as well as different time periods. This offers a powerful new tool in understanding the conditions for AMOC stability, and thus the AMOC future.

This manuscript deserves to be highlighted as it presents an incredible dataset, analysed using state-of-the-art techniques and summarised in a clear and readable form. As the reviewers pointed out, the content could easily have resulted in two articles (or even more...) - a practice that is sometimes done to increase ‘academic output’. However, the authors have chosen to provide a comprehensive overview and interpretation of the results. In addition, the site studied is of great importance for Icelandic studies of Holocene climate change.

This study employs novel methods to evaluate wildfire activity in southern Siberia during past warm periods, exploring its connections to vegetation and climate. The findings reveal that fire activity was more pronounced during the Last Interglacial than in the Holocene, driven by warmer summers and the prevalence of open forests. These results underscore the compounded influence of both vegetation changes and climate shifts on wildfire activity.
