CAPSizing ICE caps: identifying tipping points through global modelling

Objective

Ice caps have been major contributors to sea-level rise over the past decades and also in the coming century they are projected to further lose a substantial part of their volume, maintaining their position as one of the main sea-level rise contributors. One of the drawbacks of these projections, however, is that they are based on approaches that strongly simplify ice cap processes by relying on volume-area scaling methods or parameterisations derived from observations on mountain glaciers. Consequently, these projections fail to provide insights on feedback processes that can have an important impact on the future evolution of ice caps.

Within this project, I want to implement GloCAP3D, the first global 3-D ice cap evolution model in which surface mass balance and ice dynamics are explicitly accounted for, in order to improve future projections of ice caps. Firstly, I will focus on calibrating GloCAP3D, which is a crucial step to ensure accurate future ice cap projections. For this, remote sensing products and other increasingly available datasets will be included. Secondly, I will assess the role of tipping points in the future evolution of ice caps and identify potential points-of-no-return, beyond which the loss of individual ice caps is irreversible. Particular focus will be on tipping points related to the surface mass balance - elevation feedback and on tipping points resulting from a potential strong reduction in the refreezing potential. The incorporation of ice dynamics will also allow to further quantify the mass loss through frontal calving, which can regionally be a major annual mass loss driver. Finally, through this novel interdisciplinary approach it will be possible to provide improved estimates on the future sea-level contribution from ice caps. Given project’s unique nature, its outcome is anticipated to be pivotal for a number of future works, including the upcoming Intergovernmental Panel on Climate Change Assessment Report.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

MSCA-IF-EF-ST - Standard EF

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
