Summary:
We present some results on our analysis of speleothem climate proxies. We analyzed the data of about a dozen caves covering the main monsoon regions of Asia and North Australia as well as South America. From a paleo-climate perspective our aim is to identify changes in the coupling of the major areas, especially in the Indo- Australian Monsoon region, over the last 10,000 years. Using standard techniques like event synchronization, mutual information and cross-correlation to determine the network, we analyze changes in several intervals of the given time series. We are only going to mention the main results of this analysis in passing. The main point of the talk is to present the challenges climate proxy data offers and we will give a first hand report on the fun resulting from a collaboration between geologists and mathematicians.
