Dutch Polar Climate and Cryosphere Change Consortium

Samenvatting

Climate change in the polar regions is amplified and leads to a reduction in sea ice, changes in ocean circulation and ice volume. Mass loss of the Greenland ice sheet doubled over the last decade compared to the decade before and for Antarctica it even tripled. As a result, coastal risks will increase strongly if no further adaptation measures are taken. Against this background our aim is to form a Dutch Polar and Climate Community that addresses the key questions within the international science field, giving credibility to the results and implications when translated to the national policy agenda. We will do so by contributing to modelling efforts, in particular by using CESM2 and EC-Earth as tools for coupled ice-sheet climate simulations through participating in the ice sheet modelling intercomparison project (ISMIP) and the climate modelling intercomparison project (CMIP6) activities. In addition, we plan to contribute to observing physical changes in the polar regions, both by field observations as well as by using remote sensing data. We plan to do measurements along the K-transect in Greenland and at the super site on the Larsen-C ice shelf, and use gravimetry and elevation measurements to track changes in ice sheet mass. Finally, we will translate what how observed and modelled changes in the cryosphere affect regional sea level and extreme sea-level along the Dutch coast.
