This webinar is part of a series that aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. The event will look at paleo insights on climate change and how it has impacted societies - sometimes leading to their collapse.

The series is a joint activity of the Analysis, Integration, and Modeling of the Earth System (AIMES) global research project of Future Earth, the Earth Commission Working Group 1 Earth and Human Systems Intercomparison Modelling Project (EHSMIP) under the Global Commons Alliance, and the Safe Landing Climates Light House Activity of World Climate Research Program (WCRP). IIASA co-hosts the scientific secretariat of Working Group 1 of the Earth Commission and is one of the organizers of these events.


  • Collapse of complex societies – Joseph Tainter (Utah State University)
  • How climate change impacted ancient civilizations– Ann Kinzig (Arizona State University)
  • Q&A/ Discussion

Moderated by Timothy Lenton (University of Exeter)
