Abstract

Eduard Brückner, an active climate scientist 125 years ago, studied climatic changes back to 1700. He found that the climate system exhibits variations on multidecadal time scales—a bold statement to make at that time. However, he could not see inside the machinery; the mechanisms remained hidden. Considerable progress has been made since Brückner’s time, particularly in recent years. Thanks to new analytical and sampling techniques, new proxies have emerged that provide information on poorly understood aspects of the climate state. Modelling capabilities have improved and the use of simulations to study past climate has become commonplace. Furthermore, the increasing use of powerful numerical techniques such as data assimilation has triggered new data recovery efforts (see Chap. 2). If this momentum continues, we may soon be able to study continental- to hemispheric-scale weather back to the 1780s.
