Observations and modeling of permafrost

AIMES, Earth Commission, Future Earth and the WCRP Safe Landing Climates Lighthouse Activity hosted the fourth webinar in a series that aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system (MIRO board).


  • Permafrost and climate change – what are we observing ? – Hanne Hvidtfeld Christiansen
  • The Permafrost Carbon Feedback and potential tipping points - Gustaf Hugelius
  • Q&A/ Discussion

Moderated by Claire Treat (Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research) and Victor Brovkin (Max-Planck Institute for Meteorology and University of Hamburg).

The MIRO board can be accessed here.

The event recording is provided below.

All you need to know

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).

Professor Hanne H. Christiansen

Hanne H. Christiansen is a professor in Physical Geography at the University Centre in Svalbard (UNIS). Her research is within periglacial geomorphology, focusing on active layer – permafrost dynamics including the ground thermal regime, cryostratigraphy, and climatic and meteorological control on periglacial landforms, processes and sediments. She has field experience from Greenland, Svalbard and former cold climatic landscapes of Scandinavia from the last 25 years.
