Estimates of recent sea-level rise and projections of future change are subject to considerable uncertainty, associated with gaps in observations, an imperfect understanding of earth system processes, and internal variability in the
Earth system. Robust estimates and projections of sea level are critical for stakeholders and communities developing strategies to adapt to ongoing changes and mitigate future risks. This session focuses on understanding the sources of uncertainty in estimates
of sea-level rise during the instrumental era and in projections of future sea-level change. We invite contributions that use statistical, computational, mathematical, or observational approaches to understand, quantify, or decrease uncertainties in estimates
and projections of sea-level change at local, regional or global scales, and associated with processes in the ocean, cryosphere, solid Earth, atmosphere, and/or on land. We especially encourage contributions that explore new methods for reconstructing 20th
century sea-level change and probabilistic projections of future sea-level change.
