Nonlocal, Pattern-aware Response and Feedback Framework for Regional Climate Change
Parvathi Kooloth, Jian Lu, Yi Huang +4
We devise a pattern-aware feedback framework for representing the forced climate response using a suite of Green's function experiments with solar radiation perturbations. By consi…

Causal Discovery in Nonlinear Dynamical Systems using Koopman Operators
Adam Rupe, Derek DeSantis, Craig Bakker +2
We present a theory of causality in dynamical systems using Koopman operators. Our theory is grounded on a rigorous definition of causal mechanism in dynamical systems given in ter…

How optimal control of polar sea-ice depends on its tipping points
Parvathi Kooloth, Jian Lu, Craig Bakker +2
Several Earth system components are at a high risk of undergoing rapid and irreversible qualitative changes or `tipping', due to increasing climate warming. Potential tipping eleme…
