WebBackground: In dendroclimatology, tree ring chronology is typically established to elucidate the fluctuation law of climate change on interannual, interdecadal, and centennial scales.However, the environmental-related information reflected by traditional width chronology is often one-dimensional and insufficient. Consequently, only a fraction of all … WebThe Paleoclimate Modelling Group within the Paleoceanography research unit uses a hierarchy of climate and biogeochemical models to investigate the underlying mechanisms of past climate states. Numeric models help us to gain insights into the mechanisms and processes controlling and linking the various compartments of Earth’s climate system.
