Short summary
Short summary
The last deglaciation offers insights into ice-climate interactions, as paleoclimatic records document the retreat of ice sheets through a period of major climate changes. However, current ice-sheet models have difficulties reproducing key aspects of the Greenland Ice Sheet evolution. We present a new reconstruction based on an ensemble of 3000 simulations evaluated against observational constraints, improving upon previous studies, and we identify the parameters controlling model performance.

Short summary
The Antarctic Ice Sheet is subject to hysteresis, i.e. if ice is lost due to warming, a comparatively larger cooling is needed to recover the original state. Here, we show that this effect might be larger than previously assumed, with volume differences of as much as 35 metres of sea-level equivalent between retreat and regrowth. Due to the large population density along the coasts, this stresses the importance of mitigating future sea-level rise, since adapting to it will likely be much harder.

Short summary
We provide practical guidelines for producing weighted ensembles of climate models. We distinguish between two approaches, the individual- and the ensemble performance weighting approach, and formulate both in probabilistic terms, making the underlying assumptions transparent. Using constructed examples, we show the advantage of the ensemble weighting approach to account for model co-dependencies and examine how methodological choices affect the climate projections of the weighted ensemble.

This model study sets out to investigate how the collapse of the Greenland ice sheet to a virtually ice-free state due to increasing temperatures depends on the rate of this increase. We find oscillations in ice volume on millennial timescales that impact the time it takes before the ice sheet collapses, concluding that there is a mode of deterministic chaos internal to the ice sheet dynamics.

Short summary
Projections of Antarctic ice loss and associated sea level contributions over the coming centuries are linked to glacial isostatic adjustment, a process by which changing ice sheets deform the solid Earth and sea surface. We show that FastIsostasy, a computationally efficient glacial isostatic adjustment model, offers a viable approach for ice sheet modellers to accurately capture solid Earth – ice sheet feedbacks at multi-century timescales.

Short summary
Ice calving is a recent inclusion in ice sheet models and there has not been a systematic test of how well it has been implemented. We show that models can accurately represent a given rate of ice calving, properties at the ice front evolve smoothly during calving, and that there are no consistent differences in ice behaviour between various approaches to representing calving in numerical ice models. This gives us confidence in their ability for use in sea level rise prediction simulations.

This study presents a fast, physics-guided machine-learning method that downscales coarse climate fields to fine resolution while enforcing conservation of large-scale totals. Trained on regional climate simulations and driven by Earth system model output, it handles extremes and outperforms linear interpolation, providing realistic, high-resolution forcing for ice-sheet models and improving projections of Greenland’s sea-level contribution.

Short summary
Almost 3 million years ago, the planet began to experience a succession of cold and warm periods every 40,000 years. However, about 1 million years ago, they began to occur every 100,000 years. In this paper we explore how the change in the basal velocity of the ice sheets could have produced this change in behavior. On the other hand, we also see that in our model, decreasing in time the sensitivity of snowfall to temperature is also an effective mechanism with which to reproduce the records.

Tidal-water intrusions can cause warm ocean water to extend beneath grounded Antarctic ice, increasing submarine melting beyond the grounding line. Here, a new parameterization representing this effect is introduced and tested in the Yelmo ice-sheet model, revealing that tides could amplify ice loss and sea-level rise. This new parameterization shows good agreement with inferred grounding zones.

We present the testing and implementation of a calving framework for simulating the evolution of glacier fronts in grounded glacier tongues. The approach is coupled with a level set method to track changes in the glacier front over time and with an eigen-calving law that allows calving to respond to ice flow and stress conditions. The framework is evaluated using a synthetic glacier domain and, when applied to marine-terminating glaciers in Svalbard, reproduces observed calving front patterns.

Antarctica holds enough ice to raise sea levels by many meters, but its future is uncertain. Warm ocean water melts ice shelves from below, letting inland ice flow faster into the sea. By 2300, Antarctica could add 0.6–4.4 m to sea levels. Our study identifies two key factors—how strongly shelves melt and how the ice responds. These explain much of the range, and refining them in models may improve future predictions.

The Northern Patagonian Icefield is the second largest ice mass of South America, located at moderate latitudes. Using an ice-flow model which uses available atmosphere data as input and explicitly models iceberg discharge, we assess its evolution. With present climate, it will lose about 25 % of its mass during this century. Climate change strongly accelerates losses and under Paris Agreement compliance it is 36 % until 2200 and up to 68 % under a business-as-usual fossil fuel scenario.

Supraglacial lakes develop from meltwater collecting on the surface of glaciers. These lakes can drain rapidly, discharging meltwater to the glacier bed. In this study, we assess the spatial and temporal distribution of rapid drainages in Northeast Greenland using optical satellite images. After comparing rapid drainage occurrence with several environmental and geophysical parameters, little indication of the influencing conditions for a rapid drainage was found.

We introduce Nix, an ice-sheet model designed for understanding how large masses of ice behave. Nix is a computer programme that simulates the movement and temperature evolution in ice sheets. It helps us study how ice sheets respond to changes in the atmosphere and ocean. We found that ice temperatures play an essential role in determining the motion and stability of ice sheets. Nix is a useful tool for learning how climate change affects polar ice sheets.

The climate of the last 3 Myr has varied between cold and warm periods. Numerous independent mechanisms have been proposed to explain this; however, no effort has been made to study their competing effects. Here we present a simple but physically motivated model that includes these mechanisms in a modular way. We identify ice-sheet dynamics and lithosphere displacement as main triggers, but reproducing the climate records additionally requires the natural darkening of ice.

We present the open-source model ELSA, which simulates the internal age structure of large ice sheets. It creates layers of snow accumulation at fixed times during the simulation, which are used to model the internal stratification of the ice sheet. Together with reconstructed isochrones from radiostratigraphy data, ELSA can be used to assess ice sheet models and to improve their parameterization. ELSA can be used coupled to an ice sheet model or forced with its output.

We present sea level projections for Antarctica in the context of ISMIP6-2300 with several forcings but extend the simulations to 2500, showing that more than 3 m of sea level contribution could be reached. We also test the sensitivity on a basal melting parameter and determine the timing of the loss of ice in the west region. All the simulations were carried out with the ice sheet model Yelmo.

Short summary
Our study tries to understand how the ice temperature evolves in a large mass as in the case of Antarctica. We found a relation that tells us the ice temperature at any point. These results are important because they also determine how the ice moves. In general, ice moves due to slow deformation (as if pouring honey from a jar). Nevertheless, in some regions the ice base warms enough and melts. The liquid water then serves as lubricant and the ice slides and its velocity increases rapidly.

In this study, we assess Antarctic tipping points which may had been crossed during the mid-Pliocene Warm Period. For this, we use data from the PlioMIP2 ensemble. Additionally, we investigate various sources of uncertainty, like ice dynamics and bedrock configuration. Our research significantly enhances our comprehension of Antarctica's response to a warming climate, shedding light on potential future tipping points that may be surpassed.

Short summary
Ice sheets present a thickness of a few kilometres, leading to a vertical deformation of the crust of up to a kilometre. This process depends on properties of the solid Earth, which can be regionally very different. We propose a model that accounts for this often-ignored heterogeneity and run 100 000 simulation years in minutes. Thus, the evolution of ice sheets is modeled with better accuracy, which is critical for a good mitigation of climate change and, in particular, sea-level rise.

We have reconstructed the Laurentide Ice Sheet, located in North America during the Last Glacial Maximum (21 000 years ago). The absence of direct measurements raises a number of uncertainties. Here we study the impact of different physical laws that describe the friction as the ice slides over its base. We found that the Laurentide Ice Sheet is closest to prior reconstructions when the basal friction takes into account whether the base is frozen or thawed during its motion.

In this paper we present the climate component of the newly developed fast Earth system model CLIMBER-X. It has a horizontal resolution of 5°x5° and is designed to simulate the evolution of the Earth system on temporal scales ranging from decades to >100 000 years. CLIMBER-X is available as open-source code and is expected to be a useful tool for studying past climate changes and for the investigation of the long-term future evolution of the climate.

Here we investigate the numerical stability of several commonly used methods in order to determine which of them are capable of resolving the complex physics of the ice flow and are also computationally efficient. We find that the so-called DIVA solver outperforms the others. Its representation of the physics is consistent with more complex methods, while it remains computationally efficient at high resolution.

Short summary
Ice penetrating radar reflections from the Greenland ice sheet are the best available record of past accumulation and how these layers have been deformed over time by the flow of ice. Direct simulations of this archive hold great promise for improving our models and for uncovering details of ice sheet dynamics that neither models nor data could achieve alone. We present the first three-dimensional ice sheet model that explicitly simulates individual layers of accumulation and how they deform.

Short summary
The Greenland ice sheet is considered a tipping element: if temperatures exceed its threshold, it would transition to a virtually ice-free state and the ice losses could be irreversible on very long timescales. We study its stability across the full range of glacial-interglacial temperatures, as well as those expected in coming centuries. We find a future critical threshold between 1.5-2ºC of global warming, another under colder climates, and persistent hysteresis across the full range of study.
