A simple test for causality in complex systems
We show that the evolution of any dynamical system is related to a predictive asymmetry that quantifies causal connections from limited …
Eurasian ice sheet collapse was a major source of Meltwater Pulse 1A 14,600 years ago
We show that marine-based sectors of the Eurasian ice sheet complex collapsed at the Bølling transition and contributed significantly …
Transfer entropy computation using the Perron-Frobenius operator
We compute transfer entropy by estimating the invariant measure from the invariant distribution of the transfer operator approximated …
Forcing of Late Pleistocene ice volume by spatially variable summer energy
We leverage the intrinsic dynamical information in empirical records to show that the external forcing of ice volume encompasses …
Causality from palaeontological time series
We review some of the ways in which causal connections can be extracted from palaeontological time series and provide an overview of …
Common species link global ecosystems to climate change: dynamical evidence in the planktonic fossil record
We use common and widespread species of planktonic foraminifera in deep-sea sediments and show that the observed global occupancy of …
