On the Estimation of Natural and Anthropogenic Trends in Climate Records
Institut für Theoretische Physik III, Justus-Liebig-Universität Giessen, Giessen, Germany
This chapter focuses on data that exhibit long-term memory and, in addition, may be influenced by external deterministic trends.
Examples for data with long-term memory are temperature and river runoff records, and deterministic trends may be caused by
the increased emissions of greenhouse gases or increased urbanization, leading to global or urban warming. We show how long-term
correlations can be quantified in the presence of external trends and to which extent external (approximately linear) trends
can be detected in the presence of long-term memory.
