| Zusammenfassung |
| We present a recurrence-based approach to quantify an interacting, directed network of
various global climatic factors that influence global mean temperature. Extending the notion
of an earlier measure based on joint recurrences, we present a new approach to capture
directed influences among structurally different systems such as the El Niño Southern
Oscillation, volcanic activity, and solar irradiance. We find that the various climatic
phenomena interact and influence each other at multiple delays with feedbacks. All
measures estimated in the analysis are tested for significance using twin surrogates. We
stress the need to incorporate multiple, delayed interactions involving feedback
in analyses focussed on understanding and predicting global mean temperature. |
