Many variables have been used to reconstruct Chilean paleoenvironmental changes during the late Quaternary. In this paper we present an overview of a number of these variables, so-called proxies, that have been inferred from marine sediments from the Chilean continental margin and summarise the results. In general, a glacial-interglacial pattern of climate changes can be recognised in the proxy records with high-frequency variabilities superposed. The synthesis shows that the records in the Southeast Pacific are clearly dominated by a high-latitude climate forcing mechanism and that there is a noticeable gradual increase of tropical forcing moving from south to north along the South American continental margin.
