A new Seminar Series on sea-level changes, GIA and ice sheets will run from 9 March to 13 July 2021.


All events will have a start time somewhere between 16:00-18:00 UTC.


As a group under the combined auspices of the WCRP, PAGES' PALSEA working group, SERCE and the IAG sub-commission 3.4, group leaders are starting a once-a-month virtual seminar series dealing with sea-level changes, GIA, and ice sheets.

This monthly seminar series is intended to engage a broad community in advance of future workshops organized by PALSEA-SERCE and the WCRP, and to stimulate discussion and ideas for collaboration and synthesis in this multidisciplinary community.


Seminars are scheduled for the second Tuesday of each month and nominally will fall within the time window of 16:00-18:00 UTC, depending on the schedule and time zones of the speakers.

9 March at 16:30 UTC
For the inaugural meeting on 9 March at 16:30 UTC, Bob Kopp of Rutgers University will talk about the IPCC AR6 process, including the topic "What is needed from the paleo and GIA community to help refine projections of future sea-level change?" The talk will be followed by a discussion period, and this first session will also introduce the broader goals of the series.
