Test WG summary module PALSEA2

Summary

The greatest uncertainty in future sea-level rise is the responses of Earth’s remaining ice sheets. The geologic record provides archives of how ice sheets and sea level responded to past climate warming. PALSEA provides constraints on past sea-level rise ice-sheet change to improve understanding of future sea-level rise.

Goals

- Develop and refine dataset of relative sea level with improved age and elevation uncertainties, from which rates of sea-level change may be estimated.
- Develop a better understanding of the physical processes involved in ice sheet collapse and its solid earth response.
- Provide constraints on the timing, and drivers, of ice-sheet contribution to periods of Quaternary and Pliocene sea-level rise, to provide validating constraints for future developments in coupled climate-ice sheet models.
