Presentation
TRACCS-PC9-ISCLim aims to investigate any research topic related to the evolution of ice sheets and consequent interactions with climate. In particular, it will aim to better constrain projections of the contribution of ice sheets to sea level rise (including the high end) and the cascading impacts on other components of the climate system.
TRACCS-PC9-ISCLim will establish a hierarchy of numerical approaches to better assess the impacts and feedbacks of ice sheets in the climate system. This requires 4 actions to be implemented:
(i) to develop ice sheet models that can reproduce as closely as possible the currently observed changes and make 100-year projections, but also simulate large Quaternary deglaciations and rapid events.
(ii) to improve the description of ocean circulation in sub-ice-shelf cavities and fjords and its interactions with polar outlet glaciers.
(iii) to improve the description of atmospheric and surface processes and their relationship to the evolution of the physical properties of the snow cover and surface elevation.
(iv) To represent the feedbacks of ice sheets with the ocean and atmosphere through approaches of various levels of complexity, ranging from parameterizations to the explicit coupling of an ice sheet model at any resolution used by the Earth System Models.
