Natalie J. Burls, Nicky M. Wright, R. Paul Acosta, Catherine D. Bradshaw et autres

Abstract. The Miocene Epoch has emerged as an important paleoclimate model intercomparison target due to its dynamic nature, global warmth, and reconstructed atmospheric CO2 concentrations. Miocene CO2 estimates range from as low as 300–600 ppmv to as high as 800–1100 ppmv. The …

High-impact climate events and tipping dynamics: assessing scientific understanding and future challenges

Gabriele Clarissa Hegerl, Sabina Abba Omar, Alaa Al Khourdajie, Annett Bartsch et autres

This paper is motivated by growing concern about tipping dynamics and processes that can cause abrupt, self-amplifying, and irreversible changes across the Earth system and societies. It assesses current scientific understanding of the most severe climate outcomes, and proposes ways to address …

Antarctica's uncertain contribution to sea level rise

Florence Colleoni, Tim Naish, Mathieu Casado, Joanne Johnson et autres

Global mean sea level (GMSL) rise is accelerating, with rates more than doubling since the early 20th century (~2 mm yr⁻¹) to reach ~4.7 mm yr⁻¹ in recent years. By 2100, GMSL is projected to rise by 0.28–1.01 m depending on emissions …

Numerical modeling of the past stability of the Wilkes Subglacial Basin (East Antarctica) continental margin: interplay between glacio-isostatic adjustment and ice-sheet dynamics.

Mattia Di Pauli, Laura De Santis, Florence Colleoni, Paolo Stocchi et autres

The continental margin of the Wilkes Subglacial Basin (WSB) in East Antarctica presents a complex morphology, with overdeepened basins and articulated sedimentary architectures, which reflect an evolutionary history controlled by interactions between ice-sheet dynamics, ocean circulation, isostatic response, and sedimentary processes. The …

Basal Melting Variability of the Ross Ice Shelf From Mixing Ratios of Simulated Water Masses (1993–2018) and Potential Climatic Drivers

Enrico Pochini, Andrea Bergamasco, Florence Colleoni, Manuel Bensi et autres

Abstract Several water masses circulate under the Ross Ice Shelf (RIS), the largest ice shelf in Antarctica, each causing basal melting with a specific spatio‐temporal pattern. To investigate these patterns and their variability, we applied a mixing ratio analysis to simulated water …

Antarctica InSync Scientific Theme 7 - Variability, extremes, and tipping in a changing Antarctic climate

Mathieu Casado, Irina Valerievna Gorodetskaya, Louise Claire Sime, Martin Werner et autres

Antarctica is changing faster than our current observation networks can robustly assess or predict. Recent extreme events – major ice-shelf collapse, unprecedented heatwaves and abrupt, record-low winter sea ice – show that rare extremes can rapidly reshape the Antarctic system. These changes …

Antarctica InSync Science Plan

Stefanie Arndt, F. Alexander Haumann, Antje Boëtius, Signe Aaboe et autres

Antarctica InSync is a global effort to synchronise research across Antarctica and the Southern Ocean, connecting ice, ocean, land, climate, and life to protect this vital region. This roadmap paper introduces the scientific and technological motivation and action plan to build an …
