The development of new quantitative paleoclimate proxies and chronological techniques continue to improve our understanding of natural climate variability prior to the instrumental record. The quality of the information provided by spatial networks of paleoclimate records is contingent upon the fidelity of the proxies and the chronological control of the record. This session will bring together researchers aimed at developing new paleoclimate proxies, improving the fidelity of existing proxies, extending marine proxies to terrestrial archives (e.g., alkenone and tetra-ether paleothermometry) and/or improving the accuracy of age models for terrestrial paleoclimate archives. Studies using lake sediment, peat, ice cores and speleothems are all appropriate for this session. Research that relies on multiple proxies or modern calibration approaches to validate climate reconstructions are particularly encouraged.
