Fiona Turner is a post-doctoral research associate at King’s College London, interested in uncertainty quantification in climate and ice sheet models. Currently she is working as part of the H2020 funded PROTECT project, using Gaussian process and random forest emulators to build multi-centennial probabilistic projections of the Antarctic ice sheets contributions to global sea level rise.

Building probabilistic projections of the Antarctic contribution to global sea level rise using a random forest emulator

24-Apr-24

We present results from a random forest emulator simultaneously trained on two ice sheet models, Kori and PISM, forced by multiple climate models, producing multi-centennial time series of sea level contribution under two Shared Socioeconomic Pathways (SSPs), SSP1-2.6 and SSP5-8.5. We emulate the relationship between inputs, namely climate change and ice sheet model settings, and an output, sea level contribution. The emulator allows us to interpolate (and extrapolate slightly) in order to build probabilistic projections of sea level contribution to 2300 that include climate and ice sheet modelling uncertainties under all five Shared Socioeconomic Pathways (SSPs), despite only two being used in the ensemble of simulations.
