Fractal and topological dynamics for the analysis of paleoclimatic records

The paper focuses on the investigation of time series of paleoclimatic proxy records of Finlandʹs temperature and the ratio of oxygen isotope in ice cores of Greenland. Joint study of these records should improve the understanding of the climatic variability over the entire North Atlantic sector. Paleoclimatic proxy records are analyzed with the help of multifractal formalism, wavelet analysis and topological dynamics methods to reveal scaling features as well as their nonlinear dynamics and interrelationship.
