A protocol for calibrating basal melt rates in the ISMIP7 Antarctic ice sheet projections

Ronja Reese, Nicolas C. Jourdain, Xylar Asay‐Davis, Clara Burgard et autres

Abstract. Ocean-driven melting at the base of the floating ice shelves of the Antarctic Ice Sheet is an important driver of current and future ice losses. Ocean models that resolve sub-shelf melt rates at sufficient resolution are too expensive to run in …

Abstract. The glaciers of the Amundsen Sea Embayment (ASE) are some of the fastest-thinning in Antarctica. Future ice loss from this region depends on the trajectory of ocean warming. However, the response of glaciers to this warming depends to some extent on …

Ice‐Sheet–Ocean Interactions and the Reversibility of a Regime Shift Beneath Filchner‐Ronne Ice Shelf

Ronja Reese, Jan De Rydt, Kaitlin A. Naughten

Abstract Future atmospheric warming could cause an abrupt increase in ocean temperature beneath the Filchner–Ronne Ice Shelf, Antarctica, from −2.2°C to more than 0°C in a few decades. In simulations, such a transition leads to a twenty‐fold increase in sub‐shelf melt rates, …

Response of ice sheets, sea-ice and sea level in climate stabilisation and reversibility simulations using a state-of-the-art Earth System Model

Robin S. Smith, Tarkan Bilge, Thomas J. Bracegirdle, Paul Richard Holland et autres

Abstract. We have conducted an ensemble of idealised climate overshoot simulations in a state-of-the-art Earth system model in which global mean temperature is increased at a constant rate to various global warming levels (GWLs) by prescribing constant CO2 emissions, followed by a …

Comment on egusphere-2026-931

Brad Reed, Jan De Rydt, Kaitlin A. Naughten, Daniel N. Goldberg

Abstract. Coupled ice sheet-ocean models are increasingly used to investigate the complex interactions between ice dynamics and ocean forcing in West Antarctica, yet uncertainties in model parameters limit confidence in long-term sea-level projections. Among these parameters, ocean-model melt rates are typically calibrated …

Towards ocean model simulations of the Southern Ocean and Antarctic ice shelf cavities forced by CMIP historical climate data

Alethea Sara Mountford, Ronja Reese, Adrian Jenkins, Christopher Y. S. Bull et autres

Ocean-driven melting of ice shelves is the primary cause of ice loss in Antarctica, ultimately leading to global sea-level rise. However, there is still much uncertainty over the interactions between physical processes that lead to this ocean-driven melting, such as the role …
