Monday, September 20, 2021. 6:00 AM (12:00 PM CEST). Webinar: Tipping Elements, Irreversibility and Abrupt Change in the Earth System. Tim Lenton, University of Exeter; Sonia I. Seneviratne, ETH Zurich. Sponsored by the Analysis, Integration, and Modeling of the Earth System (AIMES), the Earth Commission, and The World Climate Research Programme (WCRP) The Safe Landing Climates Lighthouse Activity. Register here.

This discussion series aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. It supports efforts to increase consistency in treatment of tipping elements in the scientific community, develop a research agenda, and design joint experiments and ideas for a Tipping Element Model Intercomparison Project (TipMip).

This discussion 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).

The first event in the series provides an overall introduction. The next discussions will then dive into one Earth system tipping element in detail, i.e., Amazon rainforest, ice sheets. The events (60-90min each) will be held monthly and are open to the public.

Introduction and objectives of the webinar series – Steven Sherwood and Ricarda Winkelmann (5min)

An update on tipping elements in the climate system – Tim Lenton (20min)

Extreme events in a changing climate. Insights from IPCC AR6 - Sonia Seneviratne (20min)

Questions and discussion (20min)

The final 25min have been reserved for informal discussions on the research agenda and the development of a Tipping Element Model Intercomparison Project (TipMip).
