1ISMASS workshop 2017 peopleAn Ice Sheet Mass Balance and Sea Level (ISMASS) workshop was organized in Brussels from 11-13 January 2017 with the purpose of preparing a review paper on the contribution of Greenland and Antarctic ice sheets to future sea level under a 1.5 degree warmer climate (in line with the Paris agreement).

Discussions at the meeting led to the conclusion that the review paper would address the following: Forcing (non-linearities, SMB, circulation changes, feedbacks, ...), Advances in understanding processes - uncertainties since IPCC Assessment Report 5 (calving, GIA, basal processes, ...), Expected centennial response for Greenland and Antarctica, and Expected long-term response (including commitment). The resulting review paper is planned to feed into the IPCC Special Report on 1.5 degrees.

Participants at the meeting were Frank Pattyn (organizer), Lionel Favier, Gael Durand, Catherine Ritz (co-organizer and chair of ISMASS), Xavier Fettweis, Edward Hanna, Michiel van den Broeke, Heiko Goelzer, Xylar Asay-Davis, Alexander Robinson, Tony Payne, Helene Seroussi and Sophie Nowicki. Rob DeConto joined by Skype.
