Exploring shifts in biogeochemical cycles and mass extinction events through slow-fast dynamical systems

Description

Through data analysis and modeling, this Interdisciplinary Research Cluster (IRC) seeks to establish a connection between substantial shifts in biogeochemical cycles and mass extinction events. The challenge lies in reconciling the “fast” ecological timescales, typically ranging from 1 to 100 years, with the “slow” timescale of global biogeochemical cycles, which operate on the order of 10,000 years or more. The temporal discord between ecological dynamics and climate systems, influenced by feedback loops, necessitates the development of a mathematical framework for studying (paleo)climate tipping points related to mass extinction events. This framework specifically addresses the dynamics of “slow-fast” systems.

This project represents a continuation of the research conducted in our previous IRC, ‘Climate Tipping Phenomena in Non-autonomous Paleoecosystems,’ and involves collaboration across the Mathematics of Mass Extinctions Network.
