Title Sea-level jumps: evidence from Quaternary proxy records
CommissionCMP
Description

The latest IPCC report and subsequent debate have shown that future sea-level predictions based on computer models have inherent problems. The largest uncertainty is arguably posed by the dynamical instabilities of ice sheets, i.e. processes such as ice-sheet bed lubrication, ice-stream flow and ice-shelf calving that are notoriously difficult to model realistically. In recent years, therefore, several new (semi-) empirical approaches to future sea-level predictions have been suggested, including those based on extrapolating into the future relationships between temperature and rates of sea-level rise from either historical or palaeo-records. These novel ways of predicting future sea-level change have re-invigorated the significance of palaeo-sea level studies and highlight important lessons that can be learnt from the Quaternary record of sea-level change. Quantification of the magnitude, timing, origin and driving mechanisms responsible for periods of rapid sea-level change poses significant challenges for palaeo- and modelling communities. This session addresses these challenges by bringing together scientists working on different aspects of rapid sea-level change, including palaeo- and historic records as well as ocean-atmosphere and ice sheet modelling.
This session will focus on episodes of rapid sea-level rise from Quaternary proxy records on several timescales. In particular we invite papers on: (1) rapid sea-level rise during previous interglacials; (2) deglacial meltwater events; (3) evidence for Holocene sea-level fluctuations and their mechanisms; (4) historical sea-level accelerations; and (5) modelling abrupt sea-level change. Speakers are encouraged to explore how their findings can increase our understanding of the driving mechanisms of sea-level change and how rates of sea-level rise revealed by palaeorecords can constrain predictions of future sea-level change.
