About this event

This event is part of a series of online discussions 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 Lighthouse Activity of World Climate Research Program (WCRP).

Join AIMES, Earth Commission and WCRP for the fifth webinar in a series that aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. This novel event will include presentations on ocean tipping points from world leading researchers. Register to be kept up to date.

Helene Hewitt and Didier Swingedouw will moderate the event.

  • Ocean tipping points – an overview – Christoph Heinze
  • Recent insights on AMOC – Stefan Rahmstorf
  • Q&A/ Discussion

The talks will be followed by 20 minutes of formal discussions and, for those who wish to stay on, a further 25 minutes of informal discussions on the topic.This event is free of charge, but please register. The event will be recorded.

Speaker Information

Prof. Stefan Rahmstorf 

University of Potsdam, Institute of Physics and Astronomy; Head of Earth System Analysis, Potsdam Institute for Climate Impact Research

Prof. Rahmstorf‘s work focuses on the role of the oceans in climate change. Prof. Rahmstorf has been teaching Physics of the Oceans as a professor at Potsdam University since 2000. Rahmstorf is a member of the Academia Europaea and served from 2004-2013 in the German Advisory Council on Global Change (WBGU). He was also one of the lead authors of the 4th Assessment Report of the IPCC. In 2007 he became an Honorary Fellow of the University of Wales and in 2010 a Fellow of the American Geophysical Union. In 2017 he was the first scientist outside the US to be awarded the Climate Communication Prize of the American Geophysical Union.


Prof. Christoph Heinze 
Geophysical Institute and Bjerknes Centre for Climate Research, University of Bergen

Prof. Heinze‘s interest lie in modelling of marine biogeochemical cycles, quantifications of the global carbon cycle, simulation and interpretation of the climatic sediment record, feedbacks between biogeochemistry and climate and ocean tipping points. He served as lead author for IPCC AR4/WG1 and as review editor for IPCC AR5/WG1. Heinze is member of the Norwegian Academy of Science and Letters since 2019.
