Past and Present Sea Level Rise and Ice Sheets

PALSEA EPSL special issue. Editorial: Understanding sea-level change is impossible without both insights from paleo studies and working across disciplines Earth and Planetary Science Letters, Volumes 315–316, 15 January 2012, Pages 2-3, Mark Siddall, Glenn A. Milne, pdf.
Overview
A key question for future climate change prediction is the sensitivity of ongoing sea-level rise to increases in temperature. Peak Quaternary temperatures and sea levels were similar to modern (or meters higher) with some interglacials slightly cooler and others significantly warmer so that the paleo data set covers the range of temperature increases and sea level increases suggested for the next century. We will aim to define how we may place empirical constraints on sea-level rise over the next century using paleodata.
PALSEA pursues three closely interwoven threads...
PALSEAdate - Dating of relative sea level (RSL) indicators with a focus on
high stands and glacial terminations. PALSEA is working
towards an open-source, quality controlled RSL database.
***PALSEAdate activity - how to get involved***
PALSEAiso - The use of isostatic models to reconstruct sea level during
warm periods and glacial terminations and fingerprint
which ice sheets are implicated in such changes
PALSEAiso - workshop report on line
PALSEAice - Reconstructing and understanding past ice sheet extent to
place limits on future sea-level rise
PALSEAice - workshop report on line
