Our research is concerned with the (further) development of statistical instruments for the reconstruction of environmental changes and thus the reliability of climate proxies underlying these reconstructions. The focus is here in the methodological area of recurrence analysis, a method from non-linear physics. In particular, this instrument is intended to further investigate regime transitions in complex systems. The aim is to suit this methodology from the theoretical system research and time series analysis to the special challenges in climatology / paleoclimatology / climate dynamics. Here a major challenge is to deal with partially incomplete, not sufficiently distributed measurements of faulty climate proxies, and the non-stationary they inherent and thus pave the way for a broader application in (Geo)sciences.
