Workshop on ice-sheet future projections
The objective was to stimulate the ice-sheet community to improve methods and agree on common framework when producing ice-sheet mass balance model projections for the next 100 years.
This meeting included a report by Ryan Walker on the outputs of the “Ice sheet MIP for CMIP6” workshop that was in July 2014 and initiated ISMIP6.
Projections of ice sheets mass balance over the next centuries strongly depend on the atmospheric and oceanic forcings. During the previous IPCC assessment (AR5), several groups produced projections but the methods to force the ice sheets models differed substantially. One difficulty comes from the fact that, in the framework of IPCC, atmospheric and oceanic fields from coupled AOGCMs are necessary but are available only by the end of an IPCC Assessment, too late to be used by ice sheet modelers for their own simulations in the corresponding report. For the last IPCC (AR5) report, this reduced for instance the number of ice sheet simulations done with an RCP8.5 scenario. Methods used to initialize ice sheet models, to downscale AOGCM fields, to take into account surface mass balance-elevation feedbacks and to use ocean characteristics to initiate dynamic response of the ice sheets (calving and grounding line retreat) are other examples that have been treated very differently by the various groups. We should now take advantage of the variety of methods applied during IPCC AR5 to compare them and evaluate their impact on the results. The objective is to improve the methods and agree on common framework when producing ice-sheet mass balance model projections for the next 100 years. This should help to derive realistic ranges of uncertainties in ice sheet projections.
