Understanding sea-level change is impossible without both insights from paleo studies and working across disciplines

In recent years there have been significant advances in the observational and modeling techniques used to reconstruct and interpret paleo records that relate to changes in sea-level and/or ice extent. This special issue, which presents contributions from the PALeo constraints on Sea-level (PALSEA) PAGES/IMAGES/WUN11Past Global Changes/the International Marine Past Global Changes study/World University Network. ng group, reflects a number of these developments. Here, we provide an overview of the papers presented in this special issue. By bringing insights from very different paleo-archives and methodologies together, we hope that this special issue will encourage new ideas and collaborations in this area of climate science.
