Topic IV: Coastal sea level information

• Providing reliable uncertainties for coastal sea level predictions and projections especially for the selected regions, including those for ice sheets and glacier projections; model uncertainties; missing processes; scenario uncertainties; internal variability
• Analyzing present-day vertical land motion and their incorporation in the interpretation of regional sea level trends and mass redistribution; Correcting models for other processes contributing to regional land motion like groundwater and hydrocarbon extraction, sediment compaction, volcanism and tectonics.
• Communicating results from SeaLevel to use by respective coastal communities; Transitioning sea level variability and uncertainties from regional to local coastal scale, probabilistic information and return-period from combined effects of sea level rise and changes in extremes (e.g., storm surges).
• Downscaling full sea level uncertainty information and upper bound of sea level projections available from WP A to selected coastal locations; Using a multi-method approach to extreme-value sea level statistics.
