Abstract:Detailed records of past climatic changes, especially those related to water balance, can be used to study regional scale climatic changes associated with both natural and anthropogenic causes. Such ancient records are available from various locations around the globe. The four records presented here have sufficient time resolution to demonstrate short-lived global oscillations in parameters related to water balance during the last 7,000 y. The data indicate that sub-Milankovitch climatic events are not restricted to times of major climatic transitions but occurred throughout the Holocene. Most of the past changes due to natural variability are at least of the same order of magnitude as those predicted by various models to occur during the next century.
