Location Online
Discussion series of discussions on tipping elements, irreversibility, and abrupt change in the Earth system, focus on permafrost.

Mon, January 17, 2022 - 4:00 PM – 5:30 PM CET

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 events (60-90min each) will be held monthly and are open to the public.

This event in the series focuses on permafrost.

  • Introduction and objectives of the webinar – Victor Brovkin and Claire Treat (5min)
  • Permafrost and climate change – what are we observing ? – Hanne Hvidtfeld Christiansen (20min)
  • The Permafrost Carbon Feedback and potential tipping points - Gustaf Hugelius (20min)
  • Questions and moderated 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).
