G51B:
Regional and Global Sea Level Variability and Projections II


Session ID#: 8515

Session Description:
Sea level varies across a wide range of timescales due to a variety of geodetic, oceanographic, and climatological processes. As a result, attributing past sea level change and predicting future change requires the integration of multiple data sources, including in situ observations, remote sensing, and Earth system models.  However, limitations in spatial and temporal data coverage present a formidable challenge in projecting sea level over the coming decades and centuries. This session seeks papers that combine multiple datasets and/or models to improve prediction and physical attribution of interannual and longer variability in regional and global mean sea level change. Of particular interest are papers that provide new insights into overcoming sampling issues in the historical data record, narrow the existing large spread in future sea level projections, or provide new estimates of detection and attribution of anthropogenic signals over natural variability.
