Analyses of ice cores from polar and mountain regions have contributed to the reconstruction and understanding of the past environmental changes on timescales from years to several hundred thousand years. In this session, we welcome paleoenvironmental studies using ice cores and other methods (e.g. sediments and models). Studies on reconstruction methods, recording processes and new paleoenvironmental proxies are also welcomed. Studies with deep-sea cores, terrestrial sediment cores, tree-rings and numerical modelings on similar time and spatial scales are also important and welcomed, to discuss past environmental changes from multidisciplinary viewpoints.
