Test WG summary module PALSEA2


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. PALSEA2 provides constraints on past sea-level rise ice-sheet change to improve understanding of future sea-level rise.

- Document and synthesize data on rates, patterns, and budgets of sea-level variability during Quaternary/Pliocene warm periods and assess the ability of numerical and semi-empirical models to simulate these observations.
- Estimate the sea-level/ice-sheet response time (and governing processes) to past “warm” climates and use this data-driven information to improve future sea-level rise projections; thus bridging the gap between paleo and historical observations and future predictions.
