Understanding and quantifying Planetary Boundaries

Convener: Johan Rockström | Co-conveners: Simon Felix FahrländerECSECS, Sarah Cornell, Lauren Andersen
The Planetary Boundaries framework defines a safe operating space for humanity by identifying precautionary limits to nine critical global environmental change processes that together regulate the state of the Earth system and maintain resilience of the world’s ‘life support systems’. The framework has been widely discussed in global change science contexts, and it is increasingly being referred to in policy and business contexts, where its quantified boundaries are seen as a basis for guiding the trajectories of collective human activities. For this reason, solid scientific understanding of the interacting atmospheric, oceanic and terrestrial processes underlying Planetary Boundaries dynamics is essential.
This session invites contributions from the geophysical, biogeochemical and Earth system science communities to delve into the latest conceptual advancements, modelling techniques and research insights regarding the nine Planetary Boundaries.
We aim to bring together experts to present and discuss state-of-the-art research on the definition, quantification and analysis of the Planetary Boundaries. Oral and poster contributions are invited on studies assessing the status of single or multiple Planetary Boundaries, their spatio-temporal patterns, and their interactions. We welcome inputs on regional and global changes in major Earth system processes involved in such status changes, feedbacks that determine interactions between Planetary Boundaries, uncertainty analysis, and impacts of boundary transgressions. We also welcome conceptual proposals on how to improve assessment and application of the framework through modelling and integration of observation data, as well as cross-disciplinary discussions of the Planetary Boundaries framework.
