报告摘要：
The Earth system is a very complex and dynamical one basing on various feedbacks. This makes predictions and risk analysis even of very strong (sometime extreme) events as floods, landslides, heatwaves, and earthquakes etc. a challenging task. After introducing physical models for weather forecast already in 1922 by L.F. Richardson, a fundamental open problem has been the understanding of basic physical mechanisms and exploring anthropogenic influences on climate. A highlight was the pioneering studies by Hasselmann and Manabe who got the Physics Nobel Price in 2021.
Next, I will introduce a recently developed approach via complex networks mainly to analyze (hidden) long-range interactions in the climate system. This leads to an inverse problem: Is there a backbone-like structure underlying the climate system? To treat this problem, we have proposed a method to reconstruct and analyze a complex network from spatio-temporal data. This approach enables us to uncover teleconnections among tipping elements, in particular between Amazon Rainforest and the Tibetan Plateau, but also between the Arctic and Southwest China and California. Implications of these findings in particular for forecasting extreme events as the onset of the Indian Summer Monsoon, the Indian Ocean Dipole, or heat waves in Europe are discussed.

Jürgen Kurths is a mathematician and a physicist. He received the Ph.D.degree from the GDR Academy of Sciences and his Dr. habil. from the university of Rostock. He is a Professor of Nonlinear Dynamics at the Humboldt University, Berlin, and a Senior Advisor of the Research Domain Complexity Science of the Potsdam Institute for Climate Impact Research.
He is a Fellow of the American Physical Society, of the Royal Society of Edinburgh and of the Network Science Society and a member of the Academia Europaea. He received an Alexander von Humboldt Research Award in 2005 and 2021, the Richardson award from the European Geoscience Union in 2013, the Lagrange Award in 2022, the Chime Bell Price of the Hubei Province and the SigmaPhi Prize of the European Physical Society in 2023 (together with Nobel Price winner Michael Kosterlitz). He is Chapman Chair of the university of Fairbanks, Distinguished Professor at Fudan University, and Distinguished Adjunct Professor at KENTECH (Korea). He is a highly-cited researcher (Clarivate) since 2017 without interruptions and got eight Honorary Doctorates and Honorary Professors. He was Editor-in-chief of CHAOS – A Journal of Nonlinear Science (2015-2025) and editor of further journals.
The primary research interests of Jürgen Kurths include complex systems science, in particular synchronization, complex networks, extreme events and time series analysis and its applications in Earth Sciences, physiology, neuroscience, engineering and others.
